【正文】 er and you see a single image in the center. Seeing in stereo （立體） means seeing with two eyes working tighter, which is called stereoscopic sight. This allows you to see the world in 3D. Seeing depth helps you to judge how far it is between you and the objects you see, and then adjust to the changing angle so that you can see something clearly when you move closer or farther away. If images are ing from a single eye, however, only height and width can be perceived. So if you see with one eye, you will get a 2D image, as in a photograph. Now consider why your two eyes are on the front of your face. Think of other animals just like you. They are all hunting animals, like lions and tigers. This provides a field of sight about 180 degree wide, which is called binocular sight. On the other hand, animals that are hunted have eyes on the sides of the head, which provides nearly 360degree field of sight. However, they don39。t have stereoscopic sight. It is difficult for them to judge how far a danger is. With both stereoscopic and binocular sight, humans and hunting animals share the ability to see from side to side and to judge how far it is from other objects. If you think it would be great to have another kind of sight, perhaps with hundreds of tiny eyes like many insects do, think again! Each tiny insect eye sees only a tiny part. Besides, what if you needed glasses? Be glad for the eyesight that you have.（1）In Paragraph 2, the writer wants to. A.tell us how our two eyes worksB.show the importance of eyesC.pare our eyes with camerasD.suggest using two eyes properly（2）The underlined word perceived in Paragraph 3 means. A.setB.takenC.seenD.made（3）Which of the following statement is TRUE? A.Your right and left eyes gain the same image when looking at the same object.B.2D images can always show depth, height and width.C.Animals that are hunted usually see the world through stereoscopic sight.D.Fish with eyes on the sides of their heads have nearly 360degree field of sight.（4）In the last paragraph, the writer thinks that seeing in stereo ________. A.is similar to the way a camera worksB.is an ability humans are lucky to haveC.would be better for a wilder field of sightD.helps people to have better sight than animals（5）What is probably the best title for this passage? A.Seeing in stereoB.Protecting your eyesC.Treasuring your eyesD.Seeing with eyes【答案】 （1）A（2）C（3）D（4）B（5）A 【解析】【分析】文章大意：這是一篇說(shuō)明文，作者通過(guò)對(duì)這篇文章向他們描述了人類(lèi)所擁有的看到立體圖象的能力，人類(lèi)的眼睛就像照相機(jī)，首先捕獲到物體，然后記錄視網(wǎng)膜上，兩只眼睛從同一高度的不同的角度看物體，相互靠近一起工作，才能看到立體的圖象。 （1）細(xì)節(jié)理解題。根據(jù)our eyes are like two small cameras我們的眼睛就像兩個(gè)小相機(jī)．及Working as a team作為一個(gè)團(tuán)隊(duì)工作?？芍饕嬖V我們眼睛如何工作，故選A。 （2）詞義猜測(cè)題。文章第三段介紹了兩只眼睛看物體的話(huà)是三維立體的，而一只眼睛看的世界就是二維的，由此推斷該詞意為see，故選C。 （3）理解判斷題。根據(jù)文中的語(yǔ)句On the other hand, animals that are hunted have eyes on the sides of the head, which provides nearly 360degree field of ，魚(yú)有近360度的視野的描述是正確的，故選D。 （4）推理判斷題。根據(jù)最后一段Besides，what if you needed glasses？Be glad for the eyesight that you have，此外，如果你需要眼鏡呢？為你所擁有的視力而高興吧。可知，作者認(rèn)為看立體圖象是人類(lèi)擁有的幸運(yùn)的能力，故選B。 （5）標(biāo)題猜測(cè)題。根據(jù)Seeing in stereo means seeing with two eyes working together，which is called stereoscopic sight立體視覺(jué)是指用兩只眼睛一起工作，稱(chēng)為立體視覺(jué)。 及文章大意可知，主要講立體視覺(jué)，故選A。 【點(diǎn)評(píng)】考查閱讀理解，要注重句子與句子之間、段落與段落之間邏輯關(guān)系以及對(duì)篇章的整體理解；根據(jù)要求，結(jié)合語(yǔ)境，運(yùn)用正確的語(yǔ)法寫(xiě)出答案。10．閱讀理解 There are many colours in nature. But do you think that colour has weight? I think you39。ll say No. But I39。m afraid you are wrong. If you don39。t believe it, you may do a small experiment（實(shí)驗(yàn)）. First, put two objects with the same weight into two boxes. Then cover the boxes. Then, rap（包裹） one box with a red piece of paper, the other one with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why do you think so? A scientist found that different colours have different weights in man39。s mind. That is to say, every colour has its own weight in our mind. The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so. That is because every colour stands for（代表） a kind of light with a certain wavelength（波長(zhǎng)）. It reaches our brain through sense organs. According to this discovery, scientists say that people accept the coloursthey like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like. Or you39。ll be nervous or even get ill. For example, you 39。like blue and hate red. If you stay in a room with red windows, wallpaper and furniture（家具） for two hours, you39。ll feel you have been there for four hours, you39。ll fed you have been there for four hours. But if the room is blue, you39。I1 feel you have been there for only an hour. And, if a person walks out of a blue room and into a red room, his temperature will rise. That means our body temperature will change with different colours.（1）From the experiment, we know that . A.the two boxes have the same weightB.colours can change the weight of an objectC.the red paper is heavier than the white paperD.colours have different weights in people39。s mind（2）From the fourth paragraph, we can infer（推斷） A.the smell of colours is changeable（可變的）B.people can sense the light from coloursC.people can smell the colors through the noseD.all the colours have the same smell for the blind（3）Which of the following is TRUE? A.White colour is heavier than red colour.B.People may get ill if they refuse the colours they don39。t like.C.People can stay longer in red rooms than in blue rooms.D.People39。s body temperature will change with different colours.（4）We can infer from the last paragraph that . A.red colour is bad for our healthB.people may get nervous in a red roomC.blue colour can raise（提升） our body temperatureD.colours can influence our mood（情緒） and health（5）The passage is probably . A.a short novelB.a news reportC.a science reportD.an advertisement【答案】 （1）D（2）B（3）D（4）D（5）C 【解析】【分析】文章大意：本文介紹了自然界有許多顏色?？茖W(xué)家發(fā)現(xiàn)不同的顏色在人的頭腦中有著不同的重量。也就是說(shuō)不同的顏色重量不一樣。 （1）細(xì)節(jié)題。根據(jù) A scientist found that different colours have different weights in man39。s 。故選D。
