Put the pencil in the water. Fill the bottle with water, bend the straw and put its short end in th

2、e mouth of the bottle. Hold your finger over the mouth of the bottle, turn the bottle upside down and rest it on the pencil. Move the pencil so it holds up the weight of the bottle and keeps the bottle from squeezing(擠壓)the straw closed. Take a deep breath and blow into the straw. Keep blowing until

3、 you run out of breath. What happened? When you blow into the straw, the air rises to the top and forces water out the mouth of the bottle and into the pan. Have different people blow into the bottle and mark the water level each time; that will show you who has the largest lung volume and who has t

4、he smallest. 【語(yǔ)篇解讀】本文通過(guò)具體步驟展開(kāi)如何測(cè)試一個(gè)人的肺活量。1The purpose of doing this experiment is to .

According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret “unseen” language. For their experi

10、ment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the luciferase(熒光素酶), which is what makes fireflies(螢火蟲(chóng))glow in the dark. When the changed cabbage plant w

11、as in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciferase, they could see the plant sending out “methyl jasmonate(茉莉酸甲酯)”. While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbag

12、e plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep enemies like caterpillars(毛蟲(chóng))away. What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the dangersomething that will require furt

13、her research. However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other. 【語(yǔ)篇解讀】本文講述的是植物也有自己的語(yǔ)言。5What's the

14、 best title of the passage? APlants Can Send Some GasBPlants Can Communicate with Each OtherCThe “Unseen” Language of PlantsDPlants Can't Feel PainC主旨大意題。本文講述的是以前園丁認(rèn)為與植物說(shuō)話， 會(huì)讓它們長(zhǎng)得更好， 現(xiàn)在科學(xué)表明植物之間也是有語(yǔ)言的， 可以進(jìn)行溝通和交流。6What does the underlined word “they” in Paragraph 1 mean? AGardeners. BPlants. CScie

15、ntists. DFireflies. A推理判斷題。根據(jù)第一段提到Many gardeners believe that“talking”to their plants helps them growit turns out that they may not be crazy after all. 許多的園丁認(rèn)為與植物說(shuō)話， 能幫助它們生長(zhǎng)， 事實(shí)證明園丁沒(méi)有在說(shuō)謊。7When the plant sent out methyl jasmonate, which of the following statements is NOT true? AThe nearby cabbage pla

16、nts seemed to sense some kind of danger. BThe nearby cabbage plants started to send out a gas. CThe nearby cabbage plants tried to warn the near plants. DThe nearby cabbage plants communicated through a secret language. C細(xì)節(jié)理解題。根據(jù)第四段提到the nearby cabbage plants seemed to sense some kind of danger and

17、started to send out a gas that they normally have to keep enemies like caterpillars(毛蟲(chóng)) away.附近的圓白菜會(huì)發(fā)出一種危險(xiǎn)氣體， 使捕食者遠(yuǎn)離， 故C項(xiàng)錯(cuò)誤。8According to the experiment, plants . Adon't live a passive lifeBcan feel pain when they are cutCcan warn the other leaves about dangerDcan talk with each otherA推理判斷題。根據(jù)最后

18、一段提到this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other. 證明植物不會(huì)過(guò)著被動(dòng)的生活， 而是會(huì)移動(dòng)， 感覺(jué)甚至能彼此交流。.閱讀七選五Do you want to be a scientist？If you'd like to be one，you should lay the foundation(基礎(chǔ)) for the task ahead. 1
