Question

【題目】 If you stay in space for a long time, will your body change? Mark Kelly and Scott Kelly from the United States will show you the answer.

Mark and Scott are twins. They are both retired(退休的）NASA（美國(guó)國(guó)家航天航空局）astronauts. From 2015 to 2016,Scott spent 340 days at the international space station, while Mark stayed on the earth. People took measures of both men before, during and after the flight. They were helping with a NASA project which studies how long-term space travel influences the human body.

The full results of the study will come out in a year or two. But scientists are sharing some findings in the journal Nature.

A change in appearance was easy to see. Scott, when he returned to the earth, was 5cm taller before. Another change was that Scott's eyesight declined after he came back. He found he couldn't see clearly. He also found that he couldn't move his legs so easily like before. Scientist found that after coming back to the earth, he took a little longer to understand things and make decisions.

There were also changes that were much harder to see. As someone grows older, his telomeres(端粒）get shorter and become less effective to stop DNA from getting damaged. But during Scott's stay in space, his telomeres got longer while Mark's kept getting shorter.

Further tests on the twins are still going on.NASA plans to send people to Mars in the 2030s,and the twins' research could help them prepare for those space trips.

【1】Which of the following is Not true about Scott?

A.He has a twin brother.B.He is from the United States.

C.He has never been to space before.D.He was once a NASA astronaut.

【2】We can know that scientists did the research between the twins in order to_______.

A.see who is a better astronaut.

B.learn more about the twins' daily life

C.study how twin brothers act diferently in life

D.study how long-term space travel influences the human body

【3】What does the underlined word“declined”mean in Chinese?

【4】What didn't Scott experience while he returned to the earth?

A.He couldn't understand others as well as before.B.He could walk faster than before.

C.His telomeres became longer.D.He grew taller than before.

【5】The last paragraph mainly tells us ____________.

【解析】

文章大意：本文主要介紹了美國(guó)國(guó)家航天航空局在2015年至2016年期間做了一次實(shí)驗(yàn)，將一對(duì)退休的雙胞胎宇航員中的一個(gè)送入太空，他在太空中呆了340天，回到地球之后，科學(xué)家發(fā)現(xiàn)他身體發(fā)生了一些變化�？茖W(xué)家希望通過(guò)對(duì)他們兄弟兩人的身體變化狀況進(jìn)行對(duì)比分析，研究長(zhǎng)期太空旅行對(duì)人體的影響，從而為載人去火星的任務(wù)提前做好準(zhǔn)備。

【1】細(xì)節(jié)理解題。根據(jù)第二段第二、三行From 2015 to 2016,Scott spent 340 days at the international space station, while Mark stayed on the earth.“從2015年到2016年，斯科特在國(guó)際空間站呆了340天，馬克則留在地球上。”所以C是錯(cuò)誤的，故選C。

【2】細(xì)節(jié)理解題。根據(jù)第二段第三、四、五行They were helping with a NASA project which studies how long-term space travel influences the human body.“他們正在幫助美國(guó)宇航局的一個(gè)項(xiàng)目，該項(xiàng)目研究長(zhǎng)期太空旅行對(duì)人體的影響。”故選D。

【3】詞句推測(cè)題。根據(jù)第四段第二、三行He found he couldn't see clearly.“他發(fā)現(xiàn)他看不清楚�！笨芍�，他的視力下降了，故選A。

【4】細(xì)節(jié)理解題。根據(jù)第四段第三行He also found that he couldn't move his legs so easily like before. “他還發(fā)現(xiàn)他不能像以前那樣輕易地移動(dòng)他的腿�！惫蔬xB。

【5】主旨大意題。根據(jù)最后一段第一、二行NASA plans to send people to Mars in the 2030s,and the twins' research could help them prepare for those space trips.“美國(guó)航天局計(jì)劃在20世紀(jì)30年代將人類(lèi)送上火星，這對(duì)雙胞胎的研究可以幫助他們?yōu)檫@些太空旅行做準(zhǔn)備�！惫蔬xD。

閱讀理解題中的細(xì)節(jié)理解題，首先找出問(wèn)句中的關(guān)鍵詞，然后定位到文章具體位置，選出正確答案即可。

例如題目4中，關(guān)鍵詞是didn't Scott experience while he returned to the earth，可定位到第四段第三行He also found that he couldn't move his legs so easily like before. “他還發(fā)現(xiàn)他不能像以前那樣輕易地移動(dòng)他的腿。”故選B。
