解答 答案:66.B  細(xì)節(jié)理解題.根據(jù)第一段句子It seems to be strange to you that there is a blind spot (盲點(diǎn))on the eyes.你似乎覺(jué)得很奇怪,在眼睛上有個(gè)盲點(diǎn),可知很少有人知道眼睛上有盲點(diǎn).故選B.
67.D   詞義猜測(cè)題.根據(jù)下文But if you move the card nearer to your face,the letter will be seen again,但如果你移動(dòng)卡片靠近你的臉,將再次看到字母,可知上文說(shuō)的是當(dāng)你慢慢地向你移動(dòng)卡片,會(huì)發(fā)現(xiàn)字母L消失.所以此處disappear指的是讓某物消失,故選D.
68.C   細(xì)節(jié)理解題.根據(jù)最后一段第一行句子When the image (影像) of the letter falls on the blind spot,it won't be seen.當(dāng)這個(gè)字母落在盲點(diǎn)上的時(shí)候,它將不能被看到.故選C.
69.⑥④①③⑤②細(xì)節(jié)排序題.根據(jù)第二段內(nèi)容及其第一、二行句子Make a card about the size of a postcard and write two English letters L and R on it,做一個(gè)明信片大小的卡片,然后寫(xiě)上兩個(gè)英文字母L和R.hold the card about 80 cm away.控制卡片大約80厘米遠(yuǎn).Then close your right eye and look at the letter R only with your left eye.然后閉上你的右眼只用左眼看這個(gè)字母R.a(chǎn)s you move the card slowly towards you.你慢慢的朝你移動(dòng)卡片.可知正確順序是⑥④①③⑤②.故答案為⑥④①③⑤②.

12.At present,too much carbon dioxide(二氧化碳) makes the earth warmer and causes terrible effect to human beings.To save our planet,to save ourselves,a new lifestyle called low-carbon life(低碳生活) becomes popular.Low carbon means low energy and no waste.It is necessary for everybody to learn to live a low-carbon life.
To live a low-carbon life,we'd better save energy as much as possible.Turn off the lights and TV whenever they are not needed.If possible,use cold water to wash clothes or dishes.Take a short shower and try to take a cold one when the weather gets warm.Don't do the cooking with electricity.

14.FIFTEEN YEAR-OLD  Liu Xuyang said he has more than 30 pairs of shoes.But some are old.He doesn't want them any more.
Where should these old shoes go?To the garbage or to be recycled?
This is bow Liu began to care about old shoes.He shared his thoughts with his classmates at Beijing No.35 Middle School,Luo Hao and Yang Mengwei.The three then decided to do some research.They found out that old shoes can pollute the environment if not recycled properly.Earlier this month,their research paper won second prize in the Beijing Youth Science and Invention Competition.
The three first spent two weeks designing a questionnaire on how people deal with old shoes and how the shoes are treated.They gave over 100 questionnaires to the public,to shoemakers,garbage stations and recycling stations.
Doing the survey,they found that on average(平均),a family throws away 5.17 pairs of shoes each year.That means millions of old shoes are thrown away a year around the country.
However,most old shoes are not treated properly,according to the students.
"Usually.the old shoes are just burnt or buried(填埋)with other garbage,"said Luo.
Most of the shoes are made of chemical materials.If they are burnt or buried,they can give off gas(氣)or other things that pollute the air and rivers,said the students.
They suggest there should be big boxes in cities for people to put old shoes in.The shoes could then be taken to recycling stations to be treated.
On the other hand,the shoemakers,said the students,could use more environment-friendly material to make shoes.

61.Liu XuyangD.
A.has fifteen pairs of old shoes
B.has more than thirty pairs of old shoes
C.has more than thirty classmates in his class

A.because he decided to do some research
B.when he wanted to throw away his old shoes
C.because his thirty pairs of shoes were all very old
D.when he sent the shoes to the recycling factory
63.What does the word"questionnaire"mean in the underlined sentenceD?
A.A station to deal with the waste materials.

65.Which of the following is NOT true according to the passageA?

11.The Little ants is a special shadow puppetry performing troupe(皮影戲演出團(tuán)).Its members'average(平均的) height(身高) is 1.28 metres.Li Ming created The Little Ants in 2009.He said he started the troupe to help little people like himself who had difficulty finding other jobs.
Li's team now has about twenty members.Like most of the members,Yang Suxuan found about The Little Ants on the internet.The village girl contacted(聯(lián)系) Li Ming and decided to join the troupe,which now she calls home.
"In the past,I didn't want to communicate with others.I always felt they would laugh at me,"she recalled."Now all my family members told me I've changed.I don't know how,but I am really glad that I found a job that can support myself."
At first Yang and her workmates took the job only for a living.But gradually they have also come to understand the importance and responsibility of their job-to keep an old folk art(民間藝術(shù))alive.
Shadow puppetry was widely popular in the past,      later people gradually lost interest in it.Promoting(推廣) folk art in a modern city is not an easy job.Several times,the troupe had no money to pay the staff.In 2011,shadow puppetry was listed as a world-class cultural heritage(世界文化遺產(chǎn)).Since then,the situation for The Little Ants has got much better,and Li's small business has become successful.
"My dream is to continue promoting shadow puppetry and providing more jobs to little people,"Li said."I hope more people will understand shadow puppetry through us,and know that we little people are able to do something great too."

71.When was The Little Ants started?In 2009.
72.將文中劃線句子翻譯成漢語(yǔ).他說(shuō)他建立劇團(tuán)是為了幫助像他這樣很難找到其他工作的小人物.
73.在文中第五段空白處填上一個(gè)適當(dāng)?shù)倪B詞,使句意完整通順.but
74.What does the underlined phrase in the fifth paragraph mean?B
A.表演皮影  B.支付員工工資  C.付清債務(wù)  D.支付賬單
