分析 這是一篇科普類的閱讀理解,包含介紹科學(xué)知識、社會知識等.本文主要介紹光線的原理,以及人們?yōu)槭裁茨軌蚩匆娢矬w?是因為物體能夠反射光線.
解答 25 D 細(xì)節(jié)理解題; 從文章的第一段的句子:You can not see any object unless light from that object gets into your eyes你不能看到任何對象,除非從對象的光進(jìn)入你的眼睛:文章第二段第一行When you look at a book,it sends to your eyes some of the light which falls on it,and you see the book.可知書本反射光線是人看清書的主要原因.故推測:光線反射到我們的眼睛才能看見東西.同時本題也可以視為同義句的相互轉(zhuǎn)換.
26 C 詞義理解題;根據(jù)前文The sun,the stars,a lighted lamp are examples that can be seen by their own light太陽、星星、一盞燈都是他們自己的光可以看到的例子.Such things 指的是太陽、星星、一盞燈可以發(fā)光的東西,故推測答案為C.give off light 散發(fā)光,熱,線等.
27 D 推理題:從最后一段的Light travels so fast that the time in which it travels from the book you are reading to your eyes is so short as if there were no time at all光傳播得如此之快,以至于它從你讀到的那本書中讀到的時間是如此短暫,仿佛根本就沒有時間.說明光的速度很快,你一睜開眼,光線就到你眼中了.故推測正確答案選D.
點評 科普類的閱讀理解包含介紹科學(xué)知識、社會知識的短文.閱讀這類短文時,要以事實為中心進(jìn)行思考,抓住事物的特征、用途、相互關(guān)系等.
