You know, no plastic bottles, no plastic bags, and definitely no plastic straws. It sounded exciting. However, it was quite a c 1 ! My morning kicked off with a homemade breakfast packed in reusable glass containers. But when I tried to order my u 2 takeout juice, I had to give up because of those plastic cups and lids. As I went about my day, I faced a big problem at the grocery store. Almost everything was wrapped in plastic—from fruits and vegetables to dairy and meat. It made me realize that plastic is e 3 , making it hard to stick to my no-plastic plan. A 4 plastic turned out to be much harder than I had thought. Our world is so full of plastic products. It can’t be denied that plastic has its advantages—it can be shaped into all kinds of things. It’s tough and long-lasting and it’s really light. Making it handy for many of the products we use every day. It provides us with so much convenience that we rely h 5 on it. But here’s the thing: Using too much plastic can be harmful to the environment. The world p 6 about 400 million metric tons of plastic waste each year. According to a United Nations report, this huge amount of plastic ends up in the oceans and landfills, hurting animals and nature. My little experiment showed me how important it is to do something about it. To make a difference, we can start with simple changes. Using reusable things like cloth bags and metal straws can help us cut down on plastic. It is also cool to s 7 businesses that use eco-friendly packaging and we can join volunteer activities like cleaning up beaches. By using less plastic and encouraging others to do the same, we’re helping our planet stay healthy and happy. 【答案】1．(c)hallenge 2．(u)sual 3．(e)verywhere 4．(A)voiding 5．(h)eavily 6．(p)roduces 7．(s)upport 【导语】本文通过“无塑料日”实验，揭示塑料制品的无处不在和高度依赖性，强调其便利性背后对环境的危害，最后呼吁采取行动：减少使用、支持环保企业、参与志愿活动。 1．句意：然而，这是一个很大的挑战。根据“You know, no plastic bottles, no plastic bags, and definitely no plastic straws.

The first letters are given (在短文的空格内填入适当的词，使其内容通顺。每空格限填一词，首字母已给) In November 2007, a ship bound for South Korea struck a tower supporting the San Francisco-Oakland Bay Bridge. More than 53,000 gallons of oil were released into the San Francisco Bay. Then t 1 carried the engine fuel into the Pacific Ocean. The accident was the region’s worst oil spill in many years. More than 50 beach areas had to close. One biologist said it was the kind of event that can “push a species into extinction”. This was not the case. But the oil spill greatly harmed area’s wildlife, including birds and fish. It also d 2 the area’s fishing industry for several years. Environmentalists scrambled to save the bay’s wildlife. Michael Ziccardi is the director of a wildlife care group. He said that more than 1,000 oil-soaked birds were taken to a treatment centre. Most of the birds were sea ducks called surf scoters. They live on the water’s surface. Ziccardi explained that the oil seeps into the birds’ skin. This makes them unable to control their body temperature. It also forces them to move onto land, where they are at r 3 of starving. Fish, particularly Pacific herring, were also severely affected. The spill happened a month b 4 the start of their spawning season. That’s when herring return from the ocean to the bay to lay their eggs. Scientists figure that 14 to 29 percent of the herring spawned that season was lost due to the oil spill. And almost no herring hatched in these areas. As a result, the bay’s herring population from 2008 to 2009 was the l 5 ever recorded. The ship’s pilot pled guilty to carelessness. The companies that owned and operated the ship were fined. They had to pay more than $44 million. Most of the money was used for three p 6 . It helped restore areas affected by the spill. It improved wildlife habitats. And it upgraded recreational spaces around the bay. 【答案】1．(t)ides 2．(d)estoyed 3．(r)isk 4．(b)efore 5．(l)owest 6．(p)urposes 【导语】本文讲述了2007年一艘驶往韩国的船只撞击了支撑旧金山-奥克兰海湾大桥的塔架，导致大量石油泄漏到旧金山湾，并进一步流入太平洋，对当地生态环境和渔业造成了严重影响的事件。 1．句意：然后潮水把发动机燃料带进了太平洋。根据“carried the engine fuel into the Pacific Ocean”以及常识可知，潮水能将东西带进海洋，结合首字母提示，此处用tide“潮水”，此处表示泛指，用复数形式。故填(t)ides。 2．句意：它还破坏了该地区的渔业数年。根据“the oil spill greatly harmed area’s wildlife, including birds and fish.”可知，此处说的是石油泄漏的危害，结合首字母提示，应是破坏了该地区的渔业，destroy“破坏”，动词，结合前句可知句子是一般过去时，动词用过去式，故填(d)estoyed。 3．句意：这也迫使它们迁移到陆地上，在那里它们有挨饿的风险。根据“It also forces them to move onto land”及常识可知，迁移到陆地上，会有挨饿的风险，at risk of“有……的风险”，故填(r)isk。 4．句意：泄漏发生在鲱鱼产卵季节开始前一个月。根据“The spill happened a month...the start of their spawning season”可知，此处指在产卵季节开始前一个月，before“在……之前”，故填(b)efore。 5．句意：因此，2008年至2009年海湾的鲱鱼数量是迄今为止记录最低的。根据“Scientists figure that 14 to 29 percent of the herring spawned that season was lost due to the oil spill. And almost no herring hatched in these areas”可知，由于石油泄漏，那个季节产卵的鲱鱼中有14%到29%死亡，而且这些地区几乎没有鲱鱼孵化出来，所以数量是最低的，lowest“最低的”，故填(l)owest。 6．句意：大部分资金用于三个目的。根据“It helped restore areas affected by the spill. It improved wildlife habitats. And it upgraded recreational spaces around the bay.”可知，此处指资金用于三个目的，purpose“目的”，three修饰名词的复数形式，故填(p)urposes。 Water Park Safety Water parks can be a lot of fun for kids, as long as you keep safety in mind. Before you go, make sure the park is monitored by qualified (有资质的) lifeguards. Once there, read all posted s 300 before letting your child on any rides (many rides have age, height, weight, or health requirements, and each has a different depth of water). Teach your kids to follow all rules and directions, such as walking i 301 of running and always going down the water slide in the right position—feet first and face up. A Coast-Guard approved life jacket is a good idea, too. Know which rides are appropriate for your child’s a 302 and development. For example, wave pools can quickly go from calm to rough, putting even a good swimmer in over his or her head. Younger children can be f 303 by older kids’ splashing and roughhousing. What to Do in an Emergency Whenever a child is missing, always check the pool first. Survival d 304 on a quick rescue and restarting breathing as soon as possible. If you find a child in the water, immediately get the child out while calling 1 305 for help. If someone else is around you, have them call 911. CPR should be b 306 done by someone who is trained in CPR. When the emergency number is called, follow the instructions the emergency operators provide. If you think the child may have suffered a neck injury, such as with diving, then keep the child on his or her back and brace the neck and shoulders with your hands and forearms to help keep the neck immobilized, until emergency help arrives. Don’t let the child move. Speak in calm tones to keep the child comforted. 【答案】1．(s)igns 2．(i)nstead 3．(a)ge 4．(f)rightened 5．(d)epends 6．(l)oudly 7．(b)est/(b)etter 【导语】本文是一篇说明文，主要讲述了当带孩子去水上公园玩时，要有安全意识，以及当遇到紧急情况时该如何处理。 1．句意：到那里之后，在让孩子乘坐任何游乐设施之前，请阅读所有张贴的标志（许多游乐设施都有年龄、身高、体重或健康要求，并且每个游乐设施的水深不同）。根据句子结构可知，此处需填一个名词。根据“many rides have age, height, weight, or health requirements, and each has a different depth of water”可知，在让孩子乘坐游乐设施之前，应该阅读张贴的标志，看看这些设施适不适合你孩子玩。sign表示“标志”，是可数名词，根据前面all可知这里用复数。故填(s)igns。 2．句意：教你的孩子遵守所有的规则和指示，比如走路而不是跑步，总是以正确的姿势下滑梯——脚先着地，面朝上。根据语境“Teach your kids to follow all rules and directions, such as walking i...of running”及首字母可知，安全起见要教孩子走路而不是跑步，instead of表示“而不是”。故填(i)nstead。 3．句意：知道哪些游乐设施是适合你孩子的年龄和发育。根据句子结构可知，此处需填一个名词。根据“For example, wave pools can quickly go from calm to rough, putting even a good swimmer in over his or her head.”可知，即使是非常擅长游泳的人也可能被淹没在造浪池这样的设施里，因此，要了解哪些设施是适合你孩子年龄段的。结合首字母应用age“年龄”。故填(a)ge。 4．句意：年龄较小的孩子可能会被年龄较大的孩子溅起的水和大吵大闹吓到。根据句子结构可知此处需填一个谓语动词。根据“by older kids’ splashing and roughhousing”及首字母可知，年龄较小的孩子可能会被年龄较大的孩子吓到，frighten表示“使惊吓”，结合该空前的be动词可知，这里用被动语态，故填(f)rightened。 5．句意：幸存取决于快速救援和尽快重新开始呼吸。根据句子结构可知，此处需填一个谓语动词。结合语境“Survival d... on a quick rescue and restarting breathing as soon as possible.”及首字母，以及该空后的on，可知depend on“取决于”符合语境；因为survival作“幸存”为不可数名词，因此这里谓语动词要用三单形式。故填(d)epends。 6．句意：如果你发现有孩子溺水，立即把孩子救出来，同时大声呼救。根据句子结构可知，此处需填一个副词修饰动词calling。结合首字母及上文“If you find a child in the water”可知，loudly“大声地”符合语境。故填(l)oudly。 7．句意：心肺复苏术应该由受过心肺复苏训练的人来做最好。根据句子结构可知，此处需填一个副词来修饰done。结合首字母及下文“done by someone who is trained in CPR”可知best“最好”和better“更好”都符合语境。故填(b)est/(b)etter。 在短文的空格内填入适当的词，使其内容通顺，每空格限填一词，首字母已给 A Letter from 2070 Hi, This is the year 2070.

Free time is rare in modern life. You can see adults are always busy. You might think new technologies would give us more free time. But if you look back through h 1 , you will find it is not that simple. Back in the early 1900s in America, homes didn’t have much technology. There was no electricity, and most homes didn’t have indoor pipes for water. People had to carry water in and out by themselves. Then new useful things like toilets, fridges, and electric irons were i 2 . These were supposed to save people time. But housewives actually spent more time on housework from the 1920s to the 1960s. Why? Well, better technology makes us want more. Take washing clothes as an e 3 . Before washing machines, people washed clothes only a few times a year. With washing machines, people wash clothes more o 4 and also buy more clothes. So, there’s more work. What’s more, a 5 technology cuts time for some housework, people spend more time on other things, like taking care of children. American parents now spend almost twice as much time on their kids as they did in the 1980s. In the end, even if technology can make life a bit e 6 , it often makes us take on more work as we try to meet what society e 7 of us. 【答案】1．(h)istory 2．(i)nvented 3．(e)xample 4．(o)ften 5．(a)lthough 6．(e)asier 7．(e)xpects 【导语】本文围绕“技术进步与工作量的关系”展开，指出尽管新技术本应节省时间、增加闲暇，但实际上由于人们对生活品质的要求提高、社会期待的变化等原因，技术进步反而可能让人们承担更多工作，说明“更多技术未必带来更少工作”这一核心观点。 1．句意：但如果你回顾历史，会发现事情并非那么简单。根据下文“Back in the early 1900s in America”和首字母“h”提示可知，20世纪初的美国，所以此处是指回顾历史；考查history“历史”，不可数名词。故填(h)istory。 2．句意：后来，像马桶、冰箱和电熨斗这样有用的新东西被发明出来了。根据上文“toilets, fridges, and electric irons”和首字母“i”提示可知，马桶、冰箱、电熨斗等，这些都是被发明的物品；考查invent“发明”，动词；主语“new useful things”与动词“invent”是被动关系，应用被动语态，其结构为be done；又根据空前“were”可知，这里应用invent的过去分词invented。故填(i)nvented。 3．句意：以洗衣服为例。根据“Take washing clothes as an”和首字母“e”提示可知，此处考查take...as an example“以……为例”，动词短语。故填(e)xample。 4．句意：有了洗衣机，人们洗衣服更频繁，也买更多衣服。根据上文“people washed clothes only a few times a year”和首字母“o”提示可知，洗衣机发明前，人们一年只洗几次衣服，而有了洗衣机后，洗衣服却更频繁；考查often“常常，时常”，副词。故填(o)ften。 5．句意：此外，尽管技术减少了某些家务的时间，但人们会花更多时间在其他事情上，比如照顾孩子。分析句子结构可知，前后句子存在让步关系，结合首字母“a”提示可知，此处考查although“尽管”，连词，引导让步状语从句。故填(a)lthough。 6．句意：最后，即使技术能让生活轻松一点，但当我们试图满足社会对我们的期待时，它往往会让我们承担更多工作。根据上文“These were supposed to save people time.”和首字母“e”提示可知，技术本应能为人们节省时间，所以此处是指技术能让生活更容易些；考查easy“容易的”，形容词；又根据空后“and buy more clothes”可知，这里应用其比较级形式easier“更容易”，符合语境。故填(e)asier。 7．句意：最后，即使技术能让生活轻松一点，但当我们试图满足社会对我们的期待时，它往往会让我们承担更多工作。根据“what society … of us”和首字母“e”提示可知，此处是指社会对我们有何期望；考查expect sth. of sb.“对某人期望某事”，固定搭配；主语“society”是第三人称单数，句子时态为一般现在时，所以谓语动词应用三单形式expects。故填(e)xpects。 学科网（北京）股份有限公司 $ 期中复习之短文首字母填空10篇 （Units1-3单元话题） 单元 单元话题 Unit 1 Water 水资源与环境保护 Unit 2 Digital life 科学技术与发明创造 Unit 3 Curious minds 好奇心 本资料共10篇专题训练，从上到下每单元依次对应3-4篇单元话题专题训练 Read the passage and fill in the blanks with proper words. （在短文的空格内填入适当的词，使其内容通顺，每空格限填一词，首字母已给） Today, I decided to try something different: a whole day without using any plastic. You know, no plastic bottles, no plastic bags, and definitely no plastic straws. It sounded exciting. However, it was quite a c 1 ! My morning kicked off with a homemade breakfast packed in reusable glass containers. But when I tried to order my u 2 takeout juice, I had to give up because of those plastic cups and lids. As I went about my day, I faced a big problem at the grocery store. Almost everything was wrapped in plastic—from fruits and vegetables to dairy and meat. It made me realize that plastic is e 3 , making it hard to stick to my no-plastic plan. A 4 plastic turned out to be much harder than I had thought. Our world is so full of plastic products. It can’t be denied that plastic has its advantages—it can be shaped into all kinds of things. It’s tough and long-lasting and it’s really light. Making it handy for many of the products we use every day. It provides us with so much convenience that we rely h 5 on it. But here’s the thing: Using too much plastic can be harmful to the environment. The world p 6 about 400 million metric tons of plastic waste each year. According to a United Nations report, this huge amount of plastic ends up in the oceans and landfills, hurting animals and nature. My little experiment showed me how important it is to do something about it. To make a difference, we can start with simple changes. Using reusable things like cloth bags and metal straws can help us cut down on plastic. It is also cool to s 7 businesses that use eco-friendly packaging and we can join volunteer activities like cleaning up beaches. By using less plastic and encouraging others to do the same, we’re helping our planet stay healthy and happy. Fill in the blanks with proper words. The first letters are given (在短文的空格内填入适当的词，使其内容通顺。每空格限填一词，首字母已给) In November 2007, a ship bound for South Korea struck a tower supporting the San Francisco-Oakland Bay Bridge. More than 53,000 gallons of oil were released into the San Francisco Bay. Then t 1 carried the engine fuel into the Pacific Ocean. The accident was the region’s worst oil spill in many years. More than 50 beach areas had to close. One biologist said it was the kind of event that can “push a species into extinction”. This was not the case. But the oil spill greatly harmed area’s wildlife, including birds and fish. It also d 2 the area’s fishing industry for several years. Environmentalists scrambled to save the bay’s wildlife. Michael Ziccardi is the director of a wildlife care group. He said that more than 1,000 oil-soaked birds were taken to a treatment centre. Most of the birds were sea ducks called surf scoters. They live on the water’s surface. Ziccardi explained that the oil seeps into the birds’ skin. This makes them unable to control their body temperature. It also forces them to move onto land, where they are at r 3 of starving. Fish, particularly Pacific herring, were also severely affected. The spill happened a month b 4 the start of their spawning season. That’s when herring return from the ocean to the bay to lay their eggs. Scientists figure that 14 to 29 percent of the herring spawned that season was lost due to the oil spill. And almost no herring hatched in these areas. As a result, the bay’s herring population from 2008 to 2009 was the l 5 ever recorded. The ship’s pilot pled guilty to carelessness. The companies that owned and operated the ship were fined. They had to pay more than $44 million. Most of the money was used for three p 6 . It helped restore areas affected by the spill. It improved wildlife habitats. And it upgraded recreational spaces around the bay. Water Park Safety Water parks can be a lot of fun for kids, as long as you keep safety in mind. Before you go, make sure the park is monitored by qualified (有资质的) lifeguards. Once there, read all posted s 300 before letting your child on any rides (many rides have age, height, weight, or health requirements, and each has a different depth of water). Teach your kids to follow all rules and directions, such as walking i 301 of running and always going down the water slide in the right position—feet first and face up. A Coast-Guard approved life jacket is a good idea, too. Know which rides are appropriate for your child’s a 302 and development. For example, wave pools can quickly go from calm to rough, putting even a good swimmer in over his or her head. Younger children can be f 303 by older kids’ splashing and roughhousing. What to Do in an Emergency Whenever a child is missing, always check the pool first. Survival d 304 on a quick rescue and restarting breathing as soon as possible. If you find a child in the water, immediately get the child out while calling 1 305 for help. If someone else is around you, have them call 911. CPR should be b 306 done by someone who is trained in CPR. When the emergency number is called, follow the instructions the emergency operators provide. If you think the child may have suffered a neck injury, such as with diving, then keep the child on his or her back and brace the neck and shoulders with your hands and forearms to help keep the neck immobilized, until emergency help arrives. Don’t let the child move. Speak in calm tones to keep the child comforted. 在短文的空格内填入适当的词，使其内容通顺，每空格限填一词，首字母已给 A Letter from 2070 Hi, This is the year 2070.

I am already one of the o 1 people in this society. I remember when I was five years old, everything was very different. There were lots of trees in the parks. I could enjoy a shower for half an hour. At that time, women had beautiful hair. But now we have to shave our heads to keep them clean w 2 the use of water. I remember there were “Save Water” warnings in many public places, but nobody paid a 3 . We believed water would last forever. Now, all the rivers and lakes are either dry or polluted. Water is much more expensive than gold and diamonds. In the past, doctors s 4 adults drink eight glasses of water a day. Nowadays, I am only allowed half a glass. Most people are weak. Young people in their early 20s look as if they were in their 40s. We don’t have enough oxygen because there are f 5 trees. We have to pay for air. The air is not of very good quality, but at least we can breathe. Poor people die young. The average life expectancy (预期寿命) is 40 years.
