( ) He gave his mother a new mobile phone for her birthday, which pleased her a lot.( ) × √ 值得注意的是， 不少同学误认为只有which 才能引导非限制性定语从句， 这个观点是不正确的。使用非限制性定语从句时， 如果先行词指人，则用who, whom或whose引导； 先行词指物可用which引导； 先行词表时间或地点且在从句中作时间状语或地点状语时， 可用when, where引导。　　 名师点津 We'll graduate in July, when we will be free. 我们将于七月份毕业，那时我们就自由了。 Last Sunday they reached Nanjing, where a conference was to be held. 他们上周日到达了南京， 有个会议要在那里举行。 (2)关系代词替代情况不同 关系代词whom在限制性定语从句中作宾语时可用who代替， 但whom在非限制性定语从句中作宾语时不可用who来代替。 This is the girl (whom/who) I met in the street. 这是我在街上遇到的那个女孩。 This is Jack, whom you haven't met before. 这是杰克，你以前没见过。 在限制性定语从句中， 先行词指人时可用that 代替who/whom, 但在非限制性定语从句中先行词指人时， 不可用that 代替who/whom.　　 名师点津 She has a sister, that is a teacher.( ) She has a sister, who is a teacher.( ) × √ (3)关系代词省略情况不同 关系代词在限制性定语从句中作宾语时可以省去， 非限制性定语从句的所有关系词均不可省略。 This is the book (which/that) he lost yesterday. 这就是他昨天丢的那本书。 The book, which he lost yesterday, has been found. 他昨天丢了这本书，但现在已找到了。 5．翻译顺序不同 含限制性定语从句的句子先译从句，后译先行词，即将从句放在先行词前译；而非限制性定语从句的句子一般先译先行词，后译从句，形成两个并列分句。 Lucy has an elder brother who works in a hospital. 露西有一个在医院工作的哥哥。 Lucy has an elder brother，who works in a hospital. 露西有个哥哥，他在医院工作。 巧学活用2 用关系代词或关系副词填空 ①(2022•全国甲卷)On the 1，100-kilometer journey，the man Cao Shengkang，_____ lost his eyesight at the age of eight in a car accident，crossed 40 cities and counties in three provinces. ②(2022•新高考Ⅰ卷)The GPNP is intended to provide stronger protection for all the species ______ live within the Giant Panda Range and significantly improve the health of the ecosystem in the area. ③The performances, _______ carried forward the theme of global peace and shared future for humankind, focused on environmental protection. ④All the neighbors admire this family, _______ the parents are treating their child like a friend. who that which where which和as引导非限制性定语从句的异同 1．相同点 两者引导非限制性定语从句时，可指代主句中的部分或整个句子的内容，在从句中作主语、宾语或表语，位于主句之后，有时可互换。 The meeting was put off, as/which was exactly what we wanted. 会议被推迟了，这正是我们所希望的。　 名师点津 2．不同点 (1)as可以放在主句前或后，也可插入主句之中；而which引导的非限制性从句只能位于主句之后。 As is known to all, fish can't live without water. 众所周知，离开了水，鱼儿无法生存。 She told me she won the match, which was a lie. 她告诉我她赢得了比赛，这是一个谎言。 名师点津 (2)as常用“正如”含义，常用的结构有as we know/as is known to all(众所周知)；as often happens(正如常发生的那样)；as is often the case(情况常常如此)；as we all can see(正如我们看到的)；as is announced/expected/imagined/mentioned/said/shown/reported, as the saying goes (俗话说)等。这些结构常放在句首，偶尔也可以放在句中或句末。 As is known to all, China is a developing country. 众所周知，中国是一个发展中国家。 As the saying goes, “All roads lead to Rome”. 俗话说，“条条大路通罗马”。 名师点津 体系建构 索引 课　时　精　练 索引 基础达标 维度一　单句语法填空 1．The play, _______ style is rigidly formal，is typical of the period. 2．Mrs Smith, _____ has a lot of teaching experience, will join the school in September. 3．Actually, he is an honest and reliable person, ______ you can rely on. 4．Every student can be in harmony with foreign friends, _______ makes it easy for you to get along with them. 5．_____ is known to us, body language can give away a lot about your mood. 6．There are different stands _______ artists demonstrate their skills and teach the visitors. whose who whom which As where 7．The colorless gas without _______ we can't live is called oxygen. 8．He failed in the match，_______ was a great pity. 9．He is absorbed in work, ____ is often the case. 10．The car _____________ crashed into me belonged to Paul. which which as which/that 维度二　语法与写作 1．欢迎任何有兴趣的学生参加。 Any student _____________ is welcome to participate. 2．作为一名学生，你每天早晨应当做的第一件事就是制定适当的计划。 As a student, the first thing ______________________________ is to make a proper plan. 3．只要你坚持下去，你梦想成真的那一刻一定会到来。 So long as you stick to it, the moment ________________________________ _____________． who is interested that you should do every morning when your dream comes true will definitely come 4．这次文化活动将在艺术大厦举行，为期一周。 This cultural event is scheduled to be held in the Art Building, ______________ ___________． 5．众所周知，如果你能从失败中吸取教训，你就能避免重蹈覆辙。 _________________ , if you can learn lessons from failure, you can avoid repeating the same mistakes. which will last for a week As is known to all 维度三　语法与语篇 My sister is a college student, 1._____ is studying in Peking University.

Covered by rainforest and cloud forest, filled with 129 volcanoes and washed by both the Pacific Ocean and the Caribbean Sea, it is a dream destination for visitors. In the cloud forest, hundreds of orchid (兰花) species bloom, beautiful birds sing and butterflies flash their colorful wings, while on the Caribbean coast, four species of turtle choose the warm sands as their annual nesting sites. If you love adventure, try hiking through the lava fields of Arenal Volcano, which is among the ten most active in the world and standing at 5，437 feet tall, or walk through the cloud forest on a series of zip lines in Monteverde. And you are happy with the choice when it comes to accommodation. Will you stay in a tree house or a hotel on the beach? The options are endless. Now it is easier to get to Costa Rica. In 2016, British Airways launched a direct flight from London Gatwick to San Jose, so you can now reach the nation in less than 11 hours. Once you arrive, touring the country is simple. There are domestic flights if you are short of time. Many hotels and tour operators put together good packages to visit local highlights, or if you prefer, you can even rent a car. Costa Rica is a year-round destination, with the driest period between December and April. For the rest of the year, the scenery looks more green and amazing, with sunny mornings and showers in the afternoon. A beautiful rainforest country in Central America, Costa Rica has coastlines on both the Caribbean and Pacific Ocean and some of the world's best beaches.

Producing food that people don't consume swallows up roughly 20% of America's cropland and agricultural water, and produces greenhouse gas emissions(排放物) equal to 37 million passenger vehicles each year. Yet, 37 million Americans lack consistent access to adequate and nutritious food. NRDC's Food Matters Initiative partners cities to confront food waste. Food Matters is piloting all-round, cutting-edge strategies that are easy to follow and share. The first two strategies—and arguably the most critical ones—are to estimate a local baseline level of food waste and then assess the potential for rescuing surplus food. A baseline is necessary in order to understand the scale and natural of the problem. It is also a prerequisite(先决条件) to assessing any progress made, which will help inform future program development. Using a calculator tool NRDC developed based on the Food Matters research models，the Atlanta's Mayor's Office of Resilience had a better understanding of the qualities of wasted food and where it was likely occurring. This allowed the city to focus the attention on the solutions that were more closely related to the situation in Atlanta. As in many cities across the U．S., much of the food wasted in Atlanta occurs in households and consumer-facing businesses such as restaurants. Armed with this information, the Mayor's Office of Resilience, creates a restaurant challenge encouraging restaurants to work on the entire system of reduction, rescue, and recycling. After 90 days and participation from 6 restaurants at Atlanta's Hartsfield Jackson airport, the program rescue a 21，000 meals and saved owners over $62，000. Atlanta's restaurant challenge is one of a handful of examples where cities have engaged(吸引) consumer-facing food businesses to reduce their food waste. New York led the charge with a Mayor's challenge to restaurants.Denver recently completed a series of neighborhood restaurant challenges. Nashville has an ongoing Mayor's Food Saver Challenge including not just restaurants but other food businesses as well. Several other cities and countries throughout the country have similar business engagement success stories. 语篇解读　本文是一篇说明文。文章主要介绍了美国一些城市为应对食品浪费所作出的努力。 5．What are the data mainly about in Paragraph 1?

How much food do you buy each week? Are you someone who fills your fridge and cupboards with treats so that you'll always have something to eat and so that you'll never go hungry? 1 Throwing away unwanted food has become a big issue in the developed world. While some of us throw away unwanted items, people in other parts of world face food shortages and are starving. 2 The actual figure is 1.3 billion tons of food, which is enough to feed a billion hungry people. You may think supermarkets are mainly to blame for this mountain of food. After all, they do cast stuff that's past its sell-by date. They've also been criticized for encouraging customers to buy more than they need. 3 In Europe an incredible 53% of food waste comes from households, which results in 88 million tons of food waste a year. So instead of filling our bellies, our food is filling up landfill sites. Unfortunately, this causes greenhouse gases which eventually leads to global warming and climate change. In Denmark, a woman called Selina Juul has been working hard to tackle this problem. She convinced some supermarkets to stop selling their items in quantity so that people bought only what they needed. She's set up an education program in schools. 4 5 And when we're at home we should make the most of the food we have — using recipes that use up our leftovers or even sharing our extra food with our friends and neighbours. 语篇解读　本文是一篇说明文。文章主要介绍了近年来，发达国家正面临愈演愈烈的食品浪费现象，生活在这些国家的人们扔掉大量的食物，与其对比，另有一些国家的人们面临食物紧缺的情况。本文讨论了导致食物浪费的原因和减少浪费的办法。 A．People buy more than they need and throw too much away. B．Or maybe, you're efficient with your shopping, only buying what you need. C．But the biggest contributor to food waste is us. D．Clearly, we need to think twice when shopping. E．We simply need to stop throwing away food and enjoy it instead. F．This has helped create a 25% reduction in food waste. G．It's shocking that a third of the world's food is wasted each year.

So instead of filling our bellies, our food is filling up landfill sites. Unfortunately, this causes greenhouse gases which eventually leads to global warming and climate change. C 解析：由下一句讲到53%的食物浪费来自家庭可知，是我们(消费者自己)造成了食物浪费，承接下文。故选C项。 In Denmark, a woman called Selina Juul has been working hard to tackle this problem. She convinced some supermarkets to stop selling their items in quantity so that people bought only what they needed. She's set up an education program in schools. 4 F 解析：由上三句可知，Selina Juul女士采取措施来解决食物浪费问题，可得出她设立的教育计划也是为了减少食物浪费问题，承接上文。故选F项。 5 And when we're at home we should make the most of the food we have — using recipes that use up our leftovers or even sharing our extra food with our friends and neighbours. D 解析：此处是总结句。由上文的“食物浪费问题严重”和下一句可知，食物浪费问题很严重，下文建议读者不要浪费食物，想办法吃完拥有的食物，说明为了不浪费食物，我们买食物时，要多多思考自己到底需要多少食物，承接上下文。故选D项。 Ⅲ.完形填空 In October 2015，Shah began picking up rubbish from the beach every Sunday morning.At first，it was just him and a neighbour，and then he began 1 others to join in.Word spread and with help from social media，more volunteers got involved.
