Do you know how to be green?We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you.ReduceReduce means "use less". Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary—or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.ReuseReuse means "use again". Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup of a paper bag. It's better to use a china(陶瓷) cup and a lunch box because you can use them again.RecycleRecycle means "change things into something else". Though it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighborhood and take part in recycling programs. We should also buy products made from recycled materials, such as recycled paper, to help save trees.So please remember these three words: reduce, reuse and recycle.26.What is the passage about?A. How to produce things.B. How to help others.C. How to be green.27.Which of the following is right?A. Don't waste things.B. Always throw away old things.C. Buy too many things from abroad.28.Why is it better to use a china cup and a lunch box?A. You can burn them.B．You can use them again.C. You can change them into something else.29.To protect the environment, we should remember these three words: _______.A. waste, reuse and recycleB. repair, burn and recycleC. reduce, reuse and recycle30.Where may the passage come from?A. A dictionary.B. A magazine.C. A storybook.BIt's a popular idea that fish can't remember anything for longer than seven seconds(秒). But these days, a study found that fish have much better memories than we thought. Some kinds of fish can even remember things from as long as 12 days ago, BBC reported.In the study, researchers from MacEwan University in Canada trained African cichlids to go to a certain(具体的) area of their tank(鱼缸) to get food. They then waited for 12 days before putting them back in the tank again.This showed that they could remember their past experiences. Researchers also found that after such a long break, the fish still went to the same place as before. Finally, scientists think that African cichlids might have a good memory.An earlier study showed that they acted aggressively(有侵略性地) in front of certain fish, probably because they remembered their past fights. But until now, there was no clear evidence(证据)."If fish are able to remember a certain area with safe food, they can go back to that area without putting their lives in danger," lead researcher Trevor Hamilton told Live Science.For a long time, people numbered fish far behind monkeys, dolphins(海豚) and mice on the list of smart animals. But this study gave scientists a new understanding of their intelligence(智商).So next time you are watching your pet fish, you might feel closer to them—they may remember who you are.31.What is the popular idea about fish?A. Fish can remember things for a very short time.B. Fish can remember part of their experiences.C. Fish can remember things that happened 12 days ago.32.What did the study from MacEwan University show?①Fish may remember their past experiences.②Fish would fight for food with others.③Fish could remember where they first got food.④Fish could sleep with their eyes open.A. ①②B. ③④C. ①③33.What does the underlined word "it" in Paragraph 5 refer to?A. a living place.B. a good memory.C. special food.34.Which of the following is TRUE according to the passage?A. Researchers try to train fish how to live in the wild.B. People placed fish third on the list of clever animals.C. Your pet fish in the tank may not forget who you are.35.What's the purpose(目的) of the passage?A. To ask people to do some research on fish by themselves.B. To show that fish have better memories than people thought.C. To tell people that it is important to have a good memory.四、情景交际（共5小题；每小题2分，满分10分）A: What were you doing last night, Linda? I called at seven and you didn't pick up.A: I see. I called again at eight and you didn't answer then either.B: Oh, I was sleeping at that time.B: Yeah, I was tired. Why did you call so many times?A.

But you must go there yourself to feel its true size and beauty. The Grand Canyon is one of the greatest natural wonders of the world.The Colorado River formed the Grand Canyon over millions of years. Slowly, the river cut down through hard rock. At the same time, the land was rising. Today the canyon is 1.5 kilometers and 445 kilometers long. The oldest rocks at the bottom of the canyon are more than 1 billion years old. The width varies（改变）from about 200 metersto 29 kilometers across. The top of the canyon is about 2,300 meters above sea level on the South Rim, and about 3,000 meters on the other side. As a result, there are different kinds of plants and animals on opposite sides of the canyon. The South Rim is dry desert country. The North Rim has tall forests.The canyon looks different at different times of day, and in different seasons and weather. At sunrise and sunset the red, gold, brown and orange colors of the rocks are especially clear and bright. In winter, the canyon is partly covered with snow.The view from the South Rim of the Grand Canyon is the best. Most visitors come here and stay in campgrounds or hotels. Every point along the canyon’s edge offers a different view.The North Rim of the Canyon is quieter. It takes all day to drive there from the South Rim because there is only one bridge across the Colorado River. On the way, you go through Navado Indian lands, and a colorful pink desert called “t he Painted Desert”.31.The best way to feel the true beauty of the Grand Canyon is to .A.see its photographsB.listen to the report about itC.watch its introduction on TVD.go there yourself and visit it32.What made of the Grand Canyon?A.The earth.B.The water from the Colorado River.C.The American people.D.The strong wind.33.From the passage we can know that the of the canyon is different at different times.A.lengthB.scenery（风景）C.widthD.height34.

If you want to have a visit to the Grand Canyon, you’d better go to _______.A.the North RimB.the South RimC.the bottomD.Navado Indian LandsCWhen I was fourteen years old, I made my first visit to the United States. It wasn’t the f irst time I had been abroad (Like many English children, I had often been to France). So when I went to America I thought I wouldhave a nice easy holiday without any language problem.How wrong I was! The misunderstanding（误解）began at the airport. I was looking for a public telephone to tell my American friend Danny that I had arrived. A friendly old man saw me looking lost and asked if he could help me.“Yes,” I said, “I want to give my friend a ring.”“Well, that’s nice,” he said, “Are you getting married? But aren’t you too young?”“Who is talking about marriage（婚姻）?” I replied, “I only want to give my friend a ring to tell him I’ve arrived. Can you tell me where there is a phone box?”“Oh,” he said, “there is a phone downstairs.”When at last we met, Danny explained the misunderstanding to me.“Don’t worry,” he said to me, “I had so many difficulties at first. There are lots of words which Americans use differently in meaning from British people. You’ll soon get used to all the funny things they say. Most of the time, British and American people understand each other.”36.The writer was from .A.JapanB.FranceC.AmericaD.England37.The writer thought in America at first.A.he wouldn’t have any language problemsB.he would be lost and he had to call the police for helpC.he wouldn’t understand the AmericansD.he would have a terrible holiday38.The writer wanted to at the airport.A.have a mealB.buy a mapC.call his friendD.find an old man39.According to the friendly old man, “give somebody a ring” means “”.A.make a telephone call to somebodyB.be going to get marriedC.buy a telephone for somebodyD.ask somebody to wear a ring40.The underlined word “they” refers to .A.the old man and the boyB.the BritishC.the FrenchD.the Americans第II卷（主观题共45分）Ⅳ.词汇运用（10）（一）根据汉语提示或句意，写出句中所缺单词。

人教版八年级上册期中测试卷B卷（能力提升卷）班级：姓名：学号：分数：（考试时间：90分钟面卷分值：100分）一．选择题（共20小题，满分40分，每小题2分）1．（2分）（2019•杭州二模）房屋上的炊烟和甲、乙两车上小旗的飘动方向如图，如下判断合理的是（）A．风相对于房子是向东吹的B．甲车相对于房子一定是向东行驶的C．乙车相对于房子一定是向西行驶的D．乙车与房子的距离变大【答案】C。

【解析】由图中的信息可以判断出：因为房子的烟向左飘，所以风是向西吹；所以甲车运动状态有三种可能1、向东运动；2、静止；3、向西运动，但速度小于风速；因为乙车旗向右飘，所以乙车只能向西运动，且速度要大于风的速度，故乙车与房子的距离变小。

2．（2分）（2019•杭州一模）对一个匀速直线运动来说，下列说法正确的是（）A．速度与通过的路程成正比B．速度与运动时间成反比C．路程与运动时间成正比D．速度既与通过的路程成正比，与运动时间成反比【答案】C。

【解析】ABD、匀速直线运动的速度等于路程与所用时间的比值，它的速度保持不变，是一个定值，匀速直线运动的速度与路程和时间无关，取决它们的比值，故ABD错误；C、路程s＝vt，对于一个匀速直线运动，路程与运动时间成正比，故C正确。

3．（2分）（2019秋•深圳月考）在“测量物体运动的平均速度”实验中，当小车自斜面顶端滑下时开始计时，滑至斜面底端时停止计时。

如图所示，此过程中小车的平均速度是（）A．10cm/s B．9cm/s C．8cm/s D．7cm/s【答案】B。
