【題目】 Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru,South America. However, things went from bad to worse in March 2015 after heavy rains damaged the only power cables(電力電纜) in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.
Luckily, researchers at the University of Technology(UT)in Lima, Peru heard about their problem and found a wonderful solution. They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. The lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.
While that may sound amazing and even impossible, the science behind the ides is quite simple. As plants create their food (using the sun’s energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons—the building blocks of electrical energy. The UT team put special sticks inside the soil to capture the energy and keep it in the lamp’s batteries for later use. The researchers say a single charge can power a 50-watt Led light for two hours-enough time for local villagers to get their evening work done.
The university gave ten Plant Lamps to the villagers of Nuevo Saposoa in October 2015. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.

本文介紹了一項(xiàng)新發(fā)明——“植物電燈”,它的發(fā)明者認(rèn)為這種燈能改善熱帶雨林國(guó)家的人們的生活,因?yàn)槟抢?/span>42%的社區(qū)沒(méi)有電。
【1】
細(xì)節(jié)理解題。根據(jù)第一段中“The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.”可知,村民們被迫使用油燈,而油燈的問(wèn)題是昂貴而且危險(xiǎn),因?yàn)樗鼈儠?huì)產(chǎn)生有害氣體,對(duì)健康有害。故選D。
【2】
細(xì)節(jié)理解題。根據(jù)第3段中“As plants …, they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons—the building blocks of electrical energy.”可知,土壤里面的微生物吃掉了植物產(chǎn)生的廢物并生成了電子,電子是電能的組成部分,因此這種植物燈所產(chǎn)生的電來(lái)源于植物產(chǎn)生的廢物。故選B。
【3】
細(xì)節(jié)理解題。It can be made by local people.它可以由當(dāng)?shù)厝酥谱鳌8鶕?jù)第二段中“Luckily, researchers at the University of Technology(UT)in Lima, Peru heard about their problem and found a wonderful solution. They made a lamp that can be powered by plants and soil…”可知,植物電燈是由科技大學(xué)的研究人員制作的,當(dāng)?shù)厝瞬粫?huì)制作,所以A項(xiàng)錯(cuò)誤;It is much easier to use than oil lamps.它比油燈更容易使用。根據(jù)第三段中“The UT team put special sticks inside the soil to capture the energy and keep it in the lamp’s batteries for later use.”可知,紐約大學(xué)的研究小組在土壤中放置了特殊的樹(shù)枝來(lái)獲取能量,并將其保存在燈的電池中以備日后使用,過(guò)程比較繁瑣,而油燈只需要點(diǎn)燃就可以使用,所以植物電燈不如油燈更容易使用,所以B項(xiàng)錯(cuò)誤;It can produce all the electricity the village need.它可以提供村子所需的所有電力。根據(jù)第三段中“The researchers say a single charge can power a 50-watt Led light for two hours-enough time for local villagers to get their evening work done.”可知,研究人員說(shuō),一次充電可以為一盞50瓦的燈提供兩個(gè)小時(shí)的電力,足夠當(dāng)?shù)卮迕裢瓿赏砩系墓ぷ,但并沒(méi)有提及可以提供村子里所需的所有電力,所以C項(xiàng)錯(cuò)誤;The things it needs to make electricity are easy to find.它發(fā)電所需的東西很容易找到。根據(jù)第三段中“They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies.”可知,植物燈生電的材料主要是植物和土壤,而這些東西在雨林地區(qū)很容易找到,所以D項(xiàng)正確。故選D。
【4】
細(xì)節(jié)理解題。根據(jù)最后一段中“…believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities…”可知,植物電燈可以改善許多人們的生活,特別是一些熱帶雨林地區(qū)可以從中受益。故選A。
【5】
主旨大意題。根據(jù)文意可知,這篇短文中給我們介紹的是利馬科技大學(xué)的研究人員們發(fā)明的一種可以用植物和土壤提供的能量來(lái)照明的燈,解決了一個(gè)村莊的用電問(wèn)題,所以這篇文章的目的是為了報(bào)道這項(xiàng)新發(fā)明。故選A。

【題目】Dear Carol,
How are you? I know it's been months since I wrote you. Since I'm at college, I seem to spend a lot of time reading, and sometimes I'm too tired to write letters. The good news is that I will graduate this July.
It was great to hear that you went on that trip to Singapore. It was great! I've never been to an Asian country. Have you heard anything from that artist you met there? He sounded fun.
My life has not been very exciting, but I did do one thing interesting last week. I went to a Lenine concert with some friends. We got the cheapest seats right at the top, but the acoustics(音效) were really good, so being far away didn't matter. The audience(觀眾) were a mixture of young people and old fans of the great singer.
Lenine is a Brazilian singer, about 25 years old, with very long hair. His music is a cross between rock and New Age. He does a lot of songs about environmental problems in Brazil, So he uses instruments that sound just like birds singing in the rainforests. He did some solo(獨(dú)唱) songs and others with his group. He has a fantastic voice. The music was great, but I didn't think much of the lighting, and the setting was too formal for his kind of music.
Well, I must go now, as I have to hand in a paper tomorrow, and I haven't even started it yet!
Best wishes!
Vanessa
根據(jù)短文內(nèi)容,判斷句子正(T),誤(F)。
【1】Vanessa writes to Carol every month.
【2】Carol met an artist in Singapore who was really fun.
【3】The audience of the Lenine concert were mostly young people.
【4】Many of Lenine's songs are about the environment.
【5】Vanessa liked everything about the concert.

【題目】 Has anyone ever told you that eating carrots will help you see in the dark?This is just one of many incorrect beliefs you may have heard. Below, TEENS has picked out scientific explanations for three mistakes that people make about their eyes. Let’s take a look.
Can eating carrots improve your eyesight?
Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places.However, eating more carrots won’t help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.
If your parents have bad eyesight, will you have bad eyesight, too?
Myopia(近視)can be passed from parents to children. A study by the American Optometric Association found that if both parents are myopic, there’s a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent, and it’s down to 6 to 15 percent for kids with non-myopic parents. So if your eyesight is bad, your children might still have good vision.
Do color blind people see the world in black and white?
Color blindness doesn’t usually mean that people see the world like an old movie. They usually can’t tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue.Our eyes have cone cells(視錐細(xì)胞)that sense different wavelengths (波長(zhǎng))of light. If these cells don’t work properly, color blindness occurs.
There are different levels of color blindness. Some people are only color blind in low light.
However, in the most serious form of color blindness, everything is shades of gray.
【1】Which can help the eyes to turn light into information for the brain?
A.vitamin AB.vitamin BC.vitamin CD.vitamin D
【2】According to the article, eating carrots_____.
A.stops the brain from seeing
B.doesn’t help you see better at all
C.will give you superhuman vision.
D.is good for your eyes to some degree
【3】If both parents have myopia, their child’s chance of having good eyesight is_____.
A.40-67%B.33-60%C.23-40%D.6-15%
【4】What is the cause of color blindness, according to the text?
A.Watching movies for too long.
B.Getting too little exercise.
C.Cone cells not working properly.
D.Changes in the wavelength of light.
【5】What is the purpose of the article?
A.To offer some advice on protecting your eyes.
B.To clear up some misunderstandings about our eyes.
C.To provide help for improving your vision.
D.To explain how bad eyesight and color blindness form.
