8.Dolphins are not fish,but warm-blooded animals.They live in groups,and speak to each other in their own language.In this way they are like other animals,such as bees and birds.But dolphins are very different from almost all land animals.Their brain is nearly the same size as our own,and they live a long time---at least twenty or thirty years.
Like some animals,dolphins use sound to help them find their way around.They also make these sounds to talk to each other and to help them find food.We now know they do not use their ears to receive these sounds,but the lower part of the mouth,called the jaw.
Strangely,dolphins seem to like man,and for thousands of years there have been stories about the dolphin and its friendship with people.
There is a story about sailors in the 19th century.In a dangerous part of the sea off the coast of New Zealand,they learnt to look for a dolphin called Jack.From 1871to 1903Jack met every boat in the area and showed it the way.Then in 1903a passenger on a boat called The Penguin shot and wounded Jack.He recovered and for nine years more continued to guide all ships through the area-except for The Penguin.
Today,some people continue to kill dolphins,but many countries of the world now protect them and in these places it is against the law to kill them.

21.By telling the story of Jack the writer wanted to show thatC.
A.Jack is different from other dolphins  
B.dolphins should be protected by law
C.dolphins are friendly and clever  
D.people are cruel to animals
22.Dolphins are different from many other animals because theyA.
A.have large brains               
B.have their own language
C.are warm-blooded             
D.live in groups
23.Which of the following does the dolphin use to help it find its way around?D
A.Its ears.  B.Its nose.
C.Its eyes.   D.Its mouth.
24.Why did the sailors off the coast of New Zealand look for Jack?B
A.They enjoyed playing with him.
B.They wanted his help.
C.He was seriously wounded.
D.He was lonely and liked to be with people.

19.In the United States alone,over 100 million cell-phones are thrown away each year.Cell-phones are part of a growing mountain of electronic waste like computers and personal digital assistants.The electronic waste stream is increasing three times faster than traditional garbage as a whole.
Electronic devices contain valuable metals such as gold and silver.A Swiss study reported that while the weight of electronic goods represented by precious metals was relatively small in comparison to total waste,the concentration (含量) of gold and other precious metals was higher in So-called e-waste than in naturally occurring minerals.
   Electronic wastes also contain many poisonous metals.Even when the machines are recycled and the harmful metals removed,the recycling process often is carried out in poor countries,in practically uncontrolled ways which allow many poisonous substances to escape into the environment.
Creating products out of raw materials creates much more waste material,up to 100 times more,than the material contained in the finished products.Consider again the cell-phone,and imagine the mines that produced those metals,the factories needed to make the box and packaging(包装) it came in.Many wastes produced in the producing process are harmful as well.
  The U.S.Environmental Protection Agency notes that most waste is dangerous in that"the production,distribution,and use of products-as well as management of the resulting waste-all result in greenhouse gas release."Individuals can reduce their contribution by creating less waste at the start-for instance,buying reusable products and recycling.
  In many countries the concept of extended producer responsibility is being considered or has been put in place as an incentive (动机) for reducing waste.If producers are required to take back packaging they use to sell their products,would they reduce the packaging in the first place
Governments'incentive to require producers to take responsibility for the packaging they produce is usually based on money.Why,they ask,should cities or towns be responsible for paying to deal with the bubble wrap (气泡垫) that encased your television
   From the governments'point of view,a primary goal of laws requiring extended producer responsibility is to transfer both the costs and the physical responsibility of waste management from the government and tax-payers back to the producers.
32.Which does NOT belong to electronic waste?C
A.cell-phones    B.computers    C.television    D.personal digital assistant
33.What's the author's purpose to mention the Swiss study?C.
A.the weight of e-goods is rather small
B.natural minerals contain more precious metals
C.E-waste deserves to be made good use of
D.the percentage of precious metals is heavy in e-waste
34.The responsibility of e-waste treatment should be extendedD.
A.from producers to governments      
B.from government to individuals
C.from individuals to distributors      
D.from governments to producers
35.What does the passage mainly talk aboutB
A.how to increase e-waste.
B.how to manage e-waste.
C.what's the result of e-waste.
D.how serious the e-waste is.
3.Nothing could stop Dad.After he was put on disability for a bad back,he bought a small farm in the country,just enough to grow food for the family.He planted vegetables,fruit trees and even kept bees for honey.
And every week he cleaned Old Man McColgin's chicken house in exchange for manure(肥料).The Smell really burned the inside of your nose.When we complained about the terrible smell,Dad said the stronger the manure,the healthier the crops,and he was right.For example,just one of his cantaloupes filled the entire house with its sweet smell,and the taste was even sweeter.
As the vegetables started coming in,Dad threw himself into cooking.One day,armed with a basket of vegetables,he announced he was going to make stew(炖菜).Dad pulled out a pressure cooker and filled it up with cabbages,eggplants,potatoes,corns,onions and carrots.For about half an hour,the pressure built and the vegetables cooked.Finally,Dad turned off the stove,the pot began to cool and the pressure relief valve sprayed out a cloud of steam.If we thought Dad's pile of chicken manure was bad,this was 10times worse.When Dad took off the lid,the smell nearly knocked us out.
Dad carried the pot out and we opened doors and windows to air out the house.Just how bad was it?The neighbors came out of their houses to see if we had a gas leak!
Determined,Dad filled our plates with steaming stew and passed them around.It didn't look that bad,and after the first wave had shut down my ability to smell,it didn't offend the nose so much,either.I took a taste.It would never win a prize in a cooking competition,but it was surprisingly edible and we drank up every last drop of soup.

25.Why did Dad clean Old Man Mocolgin's chicken house regularly?D
A.To earn some money for the family.
C.To get rid of the terrible smell.
B.To set a good example to us.
D.To collect manure for his crops.
26.What can we infer about Dad's stew?B
A.It is popular among the neighbors.
C.It looks very wonderful.
B.It tastes quite delicious.
D.It contains honey and vegetables.
27.What does the underlined word"offend"in the last paragraph mean?C
A.To attract B.To airC.To upset D.To shut
28.What can we learn about Dad form the text?B
A.He is an experienced cook.
B.He has a positive attitude to life.C.He is a troublesome father.
D.He suffers a lot from his disability.
13.As shocking as the idea of baby birds growing up in a cigarette-filled home sounds,a new study suggests that some birds may benefit from putting the stuff from cigarette butts (烟蒂) into their nests.The nicotine remaining in smoked filters (滤嘴) may serve as a natural insecticide (杀虫剂),driving harmful insects away from the nests and the baby birds living within.Tobacco plants produce nicotine because it defends against insects that would otherwise eat the plants.
The butts are undoubtedly smelly.But birds are actually quite fond of smelly chemicals,such as those found in aromatic (芳香的) plants.Some nest-building species regularly fill their nests with fresh aromatics,possibly because the chemicals are good for the immune system or the development of the chicks.Alternatively,the plant chemicals might act as insecticides.
In the study,researchers at the Autonomous University of Tlaxcala in Mexico set up heat traps,which attract harmful insects,in 55nests around Mexico City.Some traps were lined with the stuff in smoked cigarette filters.The others were lined with the stuff from unsmoked cigarette filters,which did not contain nicotine and other smoking by-products.Whether the nest held eggs,chicks or nothing,the unsmoked cigarette traps collected more harmful insects,suggesting that it is the chemicals that drove harmful insects away.
In a second experiment,the researchers collected 28house sparrow nests and 29house finch (朱雀) nests from Mexico City immediately after the chicks flew out for food.They found that the more smoked filter stuff filled a nest,the fewer harmful insects it had.
The missing piece of the puzzle is whether the reduced number of harmful insects in the nests actually provided any benefit to the chicks.It is also unclear if nicotine or another chemical found in cigarettes may have turned the harmful insects out of the nests.
If the results hold,then this study is an example of wildlife adaptation to urbanization-or at least evidence that birds are smart and can still follow their noses in urban environments.
67.What may be the function of nicotine in cigarette butts for birds?B
A.To provide building materials for bird nests.
B.To drive harmful insects away from bird nests.
C.To protect the plants from being eaten by insects.
D.To attract baby birds to stay in the nests.
68.What is the first experiment aimed at?D
A.Proving that heat traps attract harmful insects in Mexico City.
B.Comparing smoked cigarette filters with unsmoked ones.
C.Analyzing what is produced from smoked cigarette filters.
D.Studying what it is that drives harmful insects away.
69.What can you infer from the passage?C
A.Birds tend to use insecticide to protect the baby birds.
B.Nicotine is the only chemical that drives harmful insects away.
C.Some insects are afraid of smelly chemicals in aromatic plants.
D.Unsmoked cigarette traps attract more harmful insects.
70.Where could you possibly see the passage?A
A.In a science report      
B.In an urbanization essay
C.In a tobacco advertisement   
D.In an anti-smoking brochure.
20.People have long noted the importance of physical activity.It can not only improve your appearance but also help to reduce the risk of some diseases,including heart disease,diabetes and even some kinds of cancer.But many people don't know how to do exercise.
Earlier this year,the Centers for Disease Control released its first ever Physical Activity Guidelines for Americans.To get the most from your exercise plan,experts say adults should get at least two and a half hours of exercise each week.More intense(剧烈的) activities reduce the suggested amount of time to one hour and fifteen minutes.And it doesn't matter whether you exercise for short periods in five days or longer time in two or three days.
Most importantly,experts say people should choose physical activity that they find fun.This helps toguaranteethat they stay with the program.According to them,walking tops the list.More than 79 million Americans walk to stay physically fit.Another popular form of exercise is jogging(慢跑).Jogging provides great physical conditioning for the heart and lungs.And it increases the flow of blood and oxygen in the body.Swimming is a third most popular sports activity in the United States.Swimming also presents less risk of muscle and joint injury because of the body's weightlessness in water.This makes it a great choice of exercise for people with special needs,like persons who are overweight.Dancing can also be a fun way to exercise.This is especially true for those who see exercise as a necessary evil.(坏事)
Whatever kind of exercise you choose,experts agree that you should start small and work your way up.Start by exercising ten minutes a day two times a week.After a few weeks,increase your time to fifteen or twenty minutes,and increase the number of days.
66.What is the author's purpose in writing the text?(no more than 15 words)To give readers some advice on how to do exercise.
67.Why should people do physical activity according to the first paragraph?(no more than 20 words)
Because physical activity can improve their appearance and help to reduce the risk of some diseases.
68.The underlined word"guarantee"in paragraph 3 probably meansensure/make sure.(no more than 2 words)
69.According to the text,which is the best choice for fat people to do exercise?(no more than 5 words)Swimming
70.What kind of physical activity do you like?Why?(no more than 20 words)(open)I like climbing because it can not only build my body,but also improve my willpower..
17.Laughing is the farthest from our minds when things are not going good.We consume ourselves in sadness,tears and anger.Laughter is healthy.(36)C Why can't we learn to laugh?It is okay to do so.Here are some ways to make that happen:
1.Call or visit your best friend
(37)G Reminisce(追忆) on funny times together and laugh a hearty laugh.If your best friend is not available,sit in your living room or in your bedroom and remember all the funny things you have experienced throughout your life.Laugh as loud as you can.
2.Surround yourself with positive people
Ask your siblings or closest friends to join you for a comedy night out.(38)E If the movie or show turns out disappointing,don't let that turn you down.Make some innocent fun about the movie or show.Your friends or siblings will join the conversation.
3.(39)B
If you have dogs,you know how it feels to see them run towards you when you come home from work.(40)F And now that you are back,it's play time.That will definitely put a smile on your face.
Laughter does not reduce the pain you are experiencing.It lends a hand to deal with the tough times with a more positive outlook.Don't fear laughter.Embrace it.

A.Spend time with your children.
B.Play with your pets.
