Question

【題目】 Not too big, not too small. Not too hot, not too cold. A newly discovered planet looks just right for life as we know it, according to an international group of astronomers.

Circling a star about 500 light years away, the planet called Kepler-186f is about the same size as Earth. It goes round its star at the right distance for liquid water on the surface. That is a necessary condition for life. But it is not exactly like Earth, it’s more of an Earth’s cousin. It’s not an Earth’s twin. It shares the same characteristics as Earth, but their parent stars are very different.

Kepler-186f circles a star that is smaller and cooler than our sun. But the planet appears to be a closer relative than most of the hundreds of others discovered so far. Some are huge gas-covered giants with thick atmospheres. Others circle too closely to their stars and are too hot for life. For the first time, we can actually say we now have a planet that is both Earth-sized and circles in its star’s livable zone.

The next step would be to look for signs of life in the atmospheres of these distant world. That would take a more advanced telescope. But budget cuts threaten that task, says University of California at Los Angeles astrophysicist Ben.

“In theory, we could do this in the next couple of decades. But in practice, because there’s no money, it’s not going to happen. It’s not going to happen in my lifetime, for example, ”said Ben. However, NASA’s Elisa Quintana believes that when the next-generation space telescope is used, it will find that we are not alone in the universe. In the meantime, the search continues for other worlds where life may find a home. 。

【1】What do we know about the newly discovered planet?

A. It was discovered by chance.

B. It has some form of life on it.

C. It has suitable conditions for life.

D. It is an ordinary planet like others.

【2】The difference between Earth and Kepler-186f is that　　　.

A. they circle different parent stars

B. they came into being at different times

C. they move in space at a different speed

D. they orbit their stars at a different distance

【3】The discovery of Kepler-186f is remarkable because　　　.

A. man has discovered a new home

B. it caused people’s interest in the universe

C. man has found a familiar planet like Earth

D. it can help man know more about Earth

【4】What does Ben worry about in the future research?

A. Lack of money. B. No cooperation.

C. His coming old age. D. His weak influence.

【3】C

【4】A

【解析】

本文是一篇科學(xué)報(bào)道。文章講了天文學(xué)家發(fā)現(xiàn)了一顆類似地球的行星，上面有適合生命存在的條件，從此地球或許不再孤單。

【1】細(xì)節(jié)理解題。答案定位在第一段Not too big, not too small. Not too hot, not too cold. A newly discovered planet looks just right for life as we know it, according to an international group of astronomers. 可知新發(fā)現(xiàn)的星球很適合生命生存，故選C。

【2】細(xì)節(jié)理解題。答案定位在第二段It shares the same characteristics as Earth, but their parent stars are very different. 可知地球和Kepler-186f的不同之處在于它們環(huán)繞的恒星不同，故選A。

【3】細(xì)節(jié)理解題。答案定位在第三段For the first time, we can actually say we now have a planet that is both Earth-sized and circles in its star’s livable zone.可知Kepler-186f的發(fā)現(xiàn)非常的舉世矚目是因?yàn)槿祟惏l(fā)現(xiàn)了一顆和地球很類似的星球，故選C。

【4】細(xì)節(jié)理解題。答案定位在最后一段“In theory, we could do this in the next couple of decades. But in practice, because there’s no money, it’s not going to happen. It’s not going to happen in my lifetime, for example, ”said Ben.可知Ben對于未來的研究很擔(dān)憂是因?yàn)橘Y金短缺，故選A。

細(xì)節(jié)理解題具體方法與步驟如下：

1.略讀材料，大概了解原文，掌握中心或主旨。文章講了天文學(xué)家發(fā)現(xiàn)了一顆類似地球的行星，上面有適合生命存在的條件，從此地球或許不再孤單。

2.按文章的體裁，作者寫作的組織模式及有關(guān)的信息詞。如for example, first, second…等預(yù)測應(yīng)該到何處尋找自己所需要的事實(shí)。

3.將精力放在尋找你所需要的細(xì)節(jié)上。快速通篇跳讀，全文掃視，找到細(xì)節(jié)出處，待找到含細(xì)節(jié)句子時(shí)，放慢速度，仔細(xì)核對比較內(nèi)容，直至找到答案。如小題1根據(jù)第一段Not too big, not too small. Not too hot, not too cold. A newly discovered planet looks just right for life as we know it, according to an international group of astronomers. 可知新發(fā)現(xiàn)的星球很適合生命生存，故選C。小題2根據(jù)第二段It shares the same characteristics as Earth, but their parent stars are very different. 可知地球和Kepler-186f的不同之處在于它們環(huán)繞的恒星不同，故選A。
