You probably use them to 1 lots of things, such as soybean milk (豆浆) , cola or milk tea. Plastic straws are small 2 they are a big problem. They are made in 10 minutes, used in 20 3 and normally remain on the earth for over 100 years since they cannot be 4 easily. But how do plastic straws get into the 5 ? Because of human mistakes, they are often thrown away, left on beaches, or blown out of bins. The waste management (管理) in some areas are so poor and remember, all gutters (排水沟) lead to our ocean. 6 , plastic straws kill ocean life. Once a 7 was found bleeding because a 12-centimeter-long plastic straw was pushed into 8 nose. How terrible! In fact, around 500 million plastic straws are used every day in the US alone. That is enough to circle 9 two-and-a-half times around our planet! If we don’t take action now, there will be 10 plastic in the ocean than fish by 2050. Luckily, more and more people around the world have realized this problem. They begin to think about 11 plastic straws are necessary or not when drinking drinks. So what can we do right now to reduce plastic pollution? The simplest way is to say “ 12 ” to single-use plastic, like straws. For example, next time if you go to a restaurant, make sure you order your drink without a straw. What if people need to use a straw? There are reusable (可再用的) straws instead. These straws can be used, 13 , and reused over and over again. Coffee house chain Starbucks (星巴克) has started to 14 lids (盖子) without straws and paper straws instead of plastic straws in almost 1000 stores in Shanghai and Shenzhen. Starbucks is not alone. McDonald’s has 15 taken action to reduce the use of plastic straws. It is hoped that more businesses and customers will work together to protect our environment. （ ）1．A．drink B．eat C．tie D．make （ ）2．A．so B．and C．or D．but （ ）3．A．seconds B．minutes C．hours D．days （ ）4．A．cut down B．written down C．broken down D．put down （ ）5．A．earth B．air C．water D．ocean （ ）6．A．For example B．Such as C．Even worse D．For one thing （ ）7．A．camel B．monkey C．turtle D．giraffe （ ）8．A．their B．its C．her D．his （ ）9．A．closely B．nearly C．specially D．particularly （ ）10．A．more B．fewer C．less D．better （ ）11．A．whether B．if C．why D．what （ ）12．A．hello B．sorry C．yes D．no （ ）13．A．repaired B．burned C．picked D．cleaned （ ）14．A．offer B．afford C．affect D．instruct （ ）15．A．still B．also C．ever D．just 五、阅读表达 Giant panda Ya Ya returned to her home in Beijing Zoo early on Monday after spending 20 years in the United States, according to the National Forestry and Grassland Administration.

It provides life (1).________ plants, animals, and people here on Earth. But how does the sun do that? It's the sun's energy that makes life on our planet possible. What is solar energy? Energy from the sun is (2).________(call) solar energy. It comes in the form of light or heat(热量). Solar energy is what makes you feel hot when you sit in the sunlight. Houses are (3).________(build) with windows, so sunlight can get inside and it can also provide heat. The sun's energy can also be used (4).________(heat) water and even food. If you have a magnifying glass(放大镜), your parents have probably warned you not (5).________(leave) it in the sun. Solar energy can make the magnifying glass burn things under it.

Using this technology, we can run a calculator(计算器) and even power cars. But what happens when clouds keep the solar panels (6).________ working?

Green is more than just a color. It also means taking special steps to protect the environment. Buying a green product is a small step everyone can take. Deciding whether a product is green, however, isn’t always easy. We need to consider the whole life cycle of the product, even after it’s of no use. Here is what we may keep in mind. The materials of a product are usually our first focus.What is it made of? Are there any harmful chemicals in it? Green products are made of more natural materials which are free from harmful chemicals, so they can be good for our physical health. Packing is important. How is a product packed? Is it over-packed? We’d better choose glass, metal and paper packing, as these can be reused or more easily recycled. We can also look for less packing or even choose unbagged products whenever possible. Location matters. Where was a product produced? Where are we buying it? Think about how much energy was used to get it to us. Try to choose local products. When it comes to food, it is a good idea to order directly from local farmers, shop at markets and buy fruits in season. Buying from stores near our houses is also a good choice, because we can go there without driving a car. Look into what the company tells us about their product. It’s easy to say that a product is “green” or “all natural”, but the words may be too good to be true. So, much of the information about a product should be taken with a grain of salt. After all, companies try to make us believe that their products are environmentally responsible. The greenest thing is certainly the one we don’t buy. Things like food and clothing are necessary for life. But many others are not. Better than buying is choosing to leave an unnecessary product in the store and doing without. It sends a message to the producer, keeps money in our pockets, reduces waste and keeps the planet healthy. （ ）1. What do we know from Paragraph 1? A. Green is just a kind of color. B. Green also means taking actions to protect the environment. C. Deciding if a product is green is easy. D. It is a big step to buy a green product. （ ）2. What is talked about in Paragraph 2? A.

We’d better choose this kind of packing except _______. A. glass B. metal C. paper D. plastic （ ）4. According to the writer, we should choose a product that is ______. A. made of unnatural materials B. produced abroad C. locally produced D. over packed （ ）5. What is the best title for the passage? A. Reducing Energy Use. B. Keeping Healthy. C. Recycling Waste. D.
