Question

【題目】 Scientists think that there has been life on the earth for hundreds of millions of years. However, we haven't found life on other plants yet. Why not?

The Earth is a planet and it goes around the Sun. Seven other planets also go around the sun. None of them has an environment with air, so people and living things cannot grow. The Sun and its planets are called the solar system(太陽系). The solar system is a small part of our galaxy（星系）.

But scientists have discovered many other galaxies in the universe. But they are far away and their light has to travel for many years to reach us. It is hard to understand how large the universe is.

So far, scientists have sent lots of spaceships to look at other plants in our solar system, and some spaceships have gone beyond the solar system. However, no one has discovered any life in space yet.

But why has no one from other plants sent us a message? Have they tried to send information to us? With so many stars in the universe, are we alone, or is there life out there in space? We don't know yet.

文章主要介紹了太陽系的相關(guān)內(nèi)容。

【1】細(xì)節(jié)理解題。根據(jù)文章第二段第一行“The Earth is a planet and it goes around the Sun. Seven other planets also go around the sun”“地球是一顆行星，繞著太陽轉(zhuǎn)。其他七顆行星也繞著太陽轉(zhuǎn)”可知，除了地球之外還有七顆行星圍繞著太陽轉(zhuǎn)，所以共有8顆行星圍繞著太陽，故選B。

【2】細(xì)節(jié)理解題。根據(jù)文章倒數(shù)第二段第一行“scientists have sent lots of spaceships to look at other plants in our solar system”“科學(xué)家們已經(jīng)發(fā)射了許多宇宙飛船來觀測太陽系中的其他行星”，故選C。

【3】細(xì)節(jié)理解題。根據(jù)文章第一段第二行“However, we haven't found life on other plants yet”“然而，我們還沒有在其他行星上發(fā)現(xiàn)生命”，故選A。

【4】細(xì)節(jié)理解題。根據(jù)文章第二段第二行“None of them has an environment with air”“他們都沒有空氣環(huán)境”可知，A說法是錯誤的；根據(jù)文章第三段第二行“It is hard to understand how large the universe is”“很難理解宇宙有多大”可知，B說法是錯誤的；根據(jù)文章第三段第一行“But scientists have discovered many other galaxies in the universe”“但是科學(xué)家在宇宙中發(fā)現(xiàn)了許多其他星系”可知，C說法是錯誤的；根據(jù)文章第二段第二、三行“The Sun and its planets are called the solar system”“太陽及其行星被稱為太陽系”可知，D說法是正確的，故選D。

【5】主旨大意題。通讀全文可知，本文主要介紹了太陽系的相關(guān)內(nèi)容，故選B。
