17．A kind of little cars may be seen in the streets in the future．People will like this kind of small cars better than the big ones．The car is as small as a bike．But it can carry two people in it．Everybody can drive it easily，just like riding a bike．Even children and old people can drive them to schools or parks．
If everyone drives such cars in the future，there will be less pollution in the air．
There will be more space for all the cars in cities，and there will also be more space for people to walk in the streets．
The little cars of the future will cost less money to buy and to drive．These little cars can go only 65kilometers an hour，so driving will be safer．The cars of the future will be fine for going around the city，but they will not be useful for a long trip．
This kind of cars can save a lot of gas．They will go 450kilometers，then they have to stop for more gas．They are nice cars，aren't they？

46．If you drive this kind of little cars for four hours，you can probably goAat most．
A.260kilometers      B.65kilometers        C.450kilometers       D.130kilometers

5．閱讀下列短文，從每題所給出的四個選項中，選出最佳選項．
The size of animals is directly connected（聯(lián)系）to the Earth's temperature．The hotter it gets，the smaller animals become．It suggests that humans could shrink（縮�。﹊f the Earth continues its warmer steps．
Scientists studied Sifrhippus，a 56-million-year-old ancestor of the modern-day horse．When Sifrhippus first appeared，he weighed only 12 pounds．Scientists used the teeth of the Sifrhippus fossils （化石）to judge its size over time．Then they compared its change of size with climate（氣候）changes．
What did the study show？During a period of 175 000 years，Sifrhippus shrank to about 8.5 pounds （just the weight of a little dog） before it increased to its original 12-pound size．Its funny change in size was well connected with the great changes of the Earth's temperature．The horse shrank as the Earth heated up by 5°C to 10°C，and grew as the Earth cooled again．
Why did heat cause the horse to shrink？Scientists think that smaller animals can throw off their body heat more easily．So they can live more successfully in warm climates．That shows a rule known as Bergmann，s rule（伯格曼定律），which says that animals of the same kind are smaller in warmer climates and larger in colder climates．（The polar bear，for example，is the largest member of the bear family．） Scientists also believe that global warming makes it difficult for animals to get enough food，which makes animals live in smaller size．
Could humans shrink，too？Quite possibly．But scientists say a lot more research has to be done before making any final conclusions．
63．From th e passage we know that the Earth's temperatureD，
A．a(chǎn)lways stays the same             B．is becoming lower
C．will rise by 10°C                     D．is becoming higher
64．What do you know about Sifrhippus？D
A．It s the biggest horse．B．It's the smallest horse．
C．It's a kind of modern horse．D．It's the earliest horse．
65．The study has shown that SifrhippusA．
A．changed it s size with climate changes
B．a(chǎn)lways had the same size
C．grew bigger in hotter environment
D．couldn't have enough food to eat
66．Which of the following would be the best title for the passage？D
A．A conclusion about horse       B．Why did the horse shrink？
C．How a horse became smaller   D．Will global warming make us shorter？

12．What does it feel like to break a bone （骨頭）？It's different for everyone，but the pain is often sharp （嚴(yán)重）．If the break is small，however，the person may not feel much pain at all．If you think that you or someone else has broken a bone，the most important things to do are to stay calm，make the hurt person comfortable，and call the doctor．Do not move the injured body part since movement could make it worse．
To treat the break，the doctor will need to take an X-ray．This gives the doctor the information he or she needs to set （接上） the bone：to put it back to its normal place．If the bone is large or it is broken in more than one place，the doctor may need to use metal pins （鋼釘） to set it．After the bone has been set，the next step is usually putting on a cast，the special，hard thing that will keep the bone in place for a month or two．
Your bones are excellent at healing themselves．Broken bones will produce many new cells （細(xì)胞） and tiny blood vessels （血脈）．These cover both ends of the broken part，and close up the break until the bone is as whole and strong as before．

61．Which of the following is the best title for the passage？D
A．How to Know if a Bone is Broken
B．How Broken Bones Heal Themselves
C．Common Causes （原因） of Broken Bones
D．What You Should Know about Broken Bones
62．When someone breaks his bone，the following should be done exceptC．
A．a(chǎn)sking the doctor for help       
B．comforting the hurt person
C．moving the injured part    
D．staying calm
63．Which is the correct order to treat the break？B
a．take an x-ray  b．use metal pins to set it  c．put it back to its normal place  d．put on cast
A．a(chǎn)→b→c→d   
B．a(chǎn)→c→b→d
C．a(chǎn)→d→c→b  
D．d→a→b→c
64．The underlined word"heal"in Paragraph 3is closest in meaning to"D"．
A．break again  
B．become worse 
C．wound or hurt    
D．become healthy again
65．Where would you probably read this passage？C
A．In a story book．

2．School is not the safe place as it used to be．How to be safer in school？How can students stay away from danger？There are many activities that students can do to learn safety in an easy way．Here are some stories from the students who have had safety classes in Xuri Middle School．
Wang Lin：About Sports Safety
Once we made up a story about sports safety．All we needed to do was to point out safe and unsafe sports behaviors in the story．From this lesson，we knew we should always do warmup（熱身）activities before playing sports and drink some water after that．
Liu Ying：About Classroom Safety
Putting on short plays is a good way to learn and enjoy ourselves．We once put on a short play about a boy called Little Naughty．He always did something naughty（淘氣的） in the classroom and got himself into trouble．In this way，we learned to behave well and get on well with each other．
Zhou Weilun：About Fire Safety
In our school，we have a fire emergency response practice（火警應(yīng)急演習(xí)） in September every year．So we know where to go if there is a fire in school．We learn to use the fire extinguisher（滅火器），too．But I don't think we should be allowed to put out the fire alone，it's too dangerous for young students like us．

根據(jù)短文內(nèi)容，選擇最佳答案．

59．The passage is probably written forC．
A．the athletes  B．the firefighters  C．the students

9．There are over 37，000 known species（種） of spiders in different shapes and sizes in the world．The largest spiders live in the rain forests of South America and are known as the"bird-eating"spiders．These spiders can grow up to 28cm long and they eat small birds．The smallest spiders are from Western Samoa．These tiny spiders are less than 0.5mm long．They live in the plants that grow on mountain rocks．
    Some people like to keep spiders as pets，but most people don't like touching them．A great number of people are afraid of them，mainly because of their poison-something will cause death or harm．However，only thirty species of spiders are very dangerous to humans．Spiders provide benefits for humans by catching and eating insects，such as flies and mosquitoes （蚊子）．
    Spiders are different from other animals，because they make webs to catch the small insects for food．The special silk of a spider's web is light and strong-five times stronger than steel．Some people have tried to raise spiders in order to collect their silk，but no one has ever succeeded in doing it．One reason is that it takes 670，000 spiders to produce half a kilo of silk，and all of these spiders need living insects for their food．Besides，spiders are usually solitary （獨自的） animals，and need to be kept alone．
    All in all，people are amazed to learn that there are so many secrets in spiders!
