【題目】根據(jù)短文內(nèi)容，選擇最佳答案。
One of my first memories as a child in the 1950s was a discussion I had with my brother in our tiny bedroom in the family house in Bethlehem, Pennsylvania.
We had heard in school about a planet called Pluto. It was the farthest, coldest, and darkest thing a child could imagine. We guessed how long it would take to die if we stood on the surface of such a frozen place wearing only the clothes we had on. We tried to figure out how much colder Pluto was than Antarctica, or than the coldest day we had ever experienced in Pennsylvania.
Pluto, which famously was downgraded from a “major planet” to a “dwarf planet”(矮星) in 2006, captured our imagination because it was a mystery that could complete our picture of what it was like at the most remote corners of our solar system
Pluto's underdog discovery story is part of what makes it so attractive. Clyde Tombaugh was a Kansas farm boy who built telescopes out of spare auto parts, old farm equipment and self-ground lenses. As an assistant at Lowell Observatory in Flagstaff, Arizona, Tombaugh's task was to search millions of stars for a moving point of light, a planet that the observatory's founder thought existed beyond the orbit of Neptune. On February 18, 1930, Tombaugh found it. Pluto was the first planet discovered by an American, and represented a moment of light in the midst of the Great Depression's dark encroachment(入侵).
Pluto is much more than something that is not a planet. It's a reminder that there are many worlds out there beyond our own and that the sky isn't the limit at all. We don't know what kinds of fantastic variations on a theme nature is capable of making until we get there to look.
（1）Why did Pluto become famous in 2006 according to the passage?
A.Because it lost its major planet status
B.Because it disappeared in the sky
C.Because it was discovered by an American
D.Because it was proved to be the coldest planet in the universe
（2）What can be a suitable title for the text?
A.An American Scientist: Clyde Tombaugh
B.Pluto was First Discovered by a Boy
C.Pluto's Strange Romance
D.The Days I Spent with My Brother in Pennsylvania
（3）What can we learn from the fourth paragraph?
A.Clyde Tombaugh discovered the darkness in the Great Depression
B.Pluto was the only planet that was discovered by Clyde Tombaugh
C.Clyde Tombaugh's job was to build telescopes for Lowell Observatory
D.Clyde Tombaugh's telescopes used for searching stars were very simple

【答案】
（1）A
（2）C
（3）D
【解析】作者童年時期從學(xué)校里聽說了一顆名叫“冥王星”的行星。它是一個孩童所能想象到的最遠(yuǎn)、最冷、最黑暗的東西。后來這顆行星遭遇降級。但對作者來說，冥王星帶來的科學(xué)興趣并沒有減弱。冥王星的意義遠(yuǎn)不只在于它不是一顆行星。它在提醒著我們，我們的世界之外還存在許多世界。除非我們到那里親眼得見，否則我們根本不知道大自然能把一個主題幻化出多少種精彩絕倫的變奏曲。
（1）A 細(xì)節(jié)題。根據(jù)第三段，冥王星之所以為人所知，是由于2006年它從“大行星”被降級為“矮行星”。
（2）C 主旨題。根據(jù)文章的整體內(nèi)容并結(jié)合文中反復(fù)出現(xiàn)的中心詞"Pluto"可推知，本文主要介紹了冥王星被發(fā)現(xiàn)的過程以及對人類的意義，故"冥王星的傳奇故事"適合作文章的標(biāo)題。
（3）D 細(xì)節(jié)題。從第四段得知，Clyde Tombaugh用于搜索恒星的望遠(yuǎn)鏡非常簡單，是用汽車部件、農(nóng)場的舊設(shè)備和自己磨成的透鏡制成的。

I used to be a physician at a hospital. I often treated children who had poisoned by medicine with older family members. The children didn’t know the medicine was danger; they just knew it tasted sweetly. Children easily open the bottle what we now use in China.

Some days before, I talked about medicines with an American. He showed me a sort of plastic bottle. The design was quite simple and I’m sure our Chinese factories can produce these bottles. The top of the bottle can be opened by pressing down on them while turning, which is difficult for most young children to do so, though grown-up can open these bottles very easily. I’m certain that the expense of making such tops would be very small. As a doctor, I’d love to see this doing. And most parents would be grateful.

Sincerely yours

Last Friday, Just before the 66th National Day holiday, I conducted interview with James Watson, a famous American scientist, talk about how to become a successful scientist. On his opinion, to be a scientist, we needed to be very fond of science. What's most, we have to keep practicing as well as learn from other successful scientist. If we want to be a successful one, besides hard-working, we are supposing to set up for a clear goal as well. James Watson also suggest that every child who is curiously about science should make your effort to realize the dream of becoming a scientist.

【題目】根據(jù)短文內(nèi)容，選擇最佳答案。
“Did you hear what happened to Adam Last Friday?” Lindsey whispers to Tori.
With her eyes shining, Tori brags, “You bet I did, Sean told me two days ago.”
Who are Lindsey and Tori talking about? It just happened to be yours truly, Adam Freedman. I can tell you that what they are saying is (a) not nice and (b) not even true. Still, Lindsey and Tori aren't very different from most students here at Linton High School, including me. Many of our conversations are gossip(閑話). I have noticed three effects of gossip: it can hurt people, it can give gossipers a strange kind of satisfaction, and it can cause social pressures in a group.
An important negative effect of gossip is that it can hurt the person being talked about. Usually, gossip spreads information about a topic-breakups, trouble at home, even dropping out-that a person would rather keep secret. The more embarrassing or shameful the secret is, the juicier the gossip it makes. Probably the worst type of gossip is the absolute lie. People often think of gossipers as harmless, but cruel lies can cause pain.
If we know that gossip can be harmful, then why do so many of us do it? Theanswer lies in another effect of gossip: the satisfaction it gives us. Sharing the latest rumor(傳言) can make a person feel important because he or she knows something that others don't. Similarly, hearing the latest rumor can make a person feel like part of the “in group.” In other words, gossip is satisfying because it gives people a sense of belonging or even superiority(優(yōu)越感).
Gossip also can have a third effect: it strengthens unwritten, unspoken rules about how people should act. Professor David Wilson explains that gossip is important in policing behaviors in a group. Translated into high school terms, this means that if everybody you hang around with is laughing at what John wore or what Jane said, then you can bet that wearing or saying something similar will get you the same kind of negative attention. The dos and don'ts conveyed through gossip will never show up in any student handbook.
The effects of gossip vary depending on the situation. The next time you feel the urge to spread the latest news, thing about why you want to gossip and what effects your “juicy story” might have.
（1）The author uses a conversation at the beginning of the passage to .
A.introduce a topic
B.present an argument
C.describe the characters
D.clarify his writing purpose
（2）Professor David Wilson thinks that gossip can .
A.provide students with written rules
B.help people watch their own behaviors
C.force schools to improve student handbooks
D.attract the police's attention to group behaviors
（3）What advice does the author give in the passage?
A.Never become a gossiper
B.Stay away from gossipers
C.Don't let gossip turn into lies
D.Think twice before you gossip.

【題目】When others get off the train to finally go home, Leonie Muller stays behind. That’s because she is already home: The train is her apartment, and she says she likes it that way. The German college student gave up her apartment in spring.“It all started with an argument I had with my landlord,” Muller told The Washington Post via e-mail.“I immediately decided I didn't want to live there anymore and then I realized: Actually,I didn’t want to live anywhere anymore.”

Instead, she bought a subscription (會員費) that allows her to board every train in the country for free. Now, Muller washes her hair in the train bathroom and writes her college papers while traveling at a speed of up to 190 mph.She says that she enjoys the freedom since she gave up her apartment.“I really feel at home on trains.It’s like being on vacation all the time,”Muller said.

Last summer holiday, I took part in a teaching project and volunteered(teach) in a countryside primary school for two weeks.
When we arrived at the school, though shocked by the poor living conditions, we quickly adapted to the life there. My good friend Tom and I were in charge of the third year students, (consist) of just 18 boys and girls. We not only taught them English and maths, but also organized some after-school (activity) for them. Gradually, I found that many of the students were actually quite 6(talent). But some had to leave school early, which is(large) because their families were under heavy financial pressure, and they had to find a job to support the family.
As well as giving lessons, we also helped set up a reading room in the school students hardly had any access good reading materials except textbooks. With the help of school staff and students, we cleaned out an abandoned classroom. When we placed the books students and teachers in my high school (donate) onto the shelves, I found the students were more than excited and (dive) into reading there.
Two weeks quickly passed and we had to leave. I did not know how much we had actually taught them, but for me I learned a great deal—cherish what I possess and study harder.

【題目】D

Would You Pay To Eat In A Dumpster(垃圾箱)?

Most of us don’t reach for that gnarled(多瘤的) carrot when selecting our produce at the local supermarket. That’s exactly why Americans waste up to 40% of edible food every year. This unbelievable number has sparked the ＂ugly food＂ movement, inspiring many companies to sell ugly fruit and vegetables to consumers, rather than throwing them in the trash.

One San Francisco organization is taking a unique approach. The Salvage Supperclub hosts fancy dinners inside dumpsters where they serve dishes entirely prepared with food that would have otherwise gone to waste.

Josh Treuhaft, founder of these ugly food dinners, originally came up with the idea to bring about the awareness of America’s food waste problem. ＂There is undeveloped potential in their food that for some reason, not to their own fault, is going to waste,＂ he told Seeker’s Laura Ling.

Treuhaft isn’t alone in his effort to reduce America’s food waste. A change.org petition last year called for Whole Foods to become part of the ugly food movement. They sold misshapen fruits and vegetables in Northern California stores.

Selling imperfect produce is still relatively rare right now, which can be partially attributed to a supply issue rather than a lack of willing participants. Raley’s, a Sacramento-based grocery chain, started an ugly food pilot program called ＂Real Good＂, but discontinued it after 90 days saying they had ＂some challenges sourcing the product＂. A grower might have large amounts of ugly produce one year due to terrible weather, but much less the next year if the weather is better. Harvests constantly vary and retailers are more likely to buy ugly produce in large number rather than just a few pounds at a time.

This is why organizations like the Salvage Supperclub are playing an important role in the prevention of food waste. The Salvage Supperclub takes it a step further by not only buying the ugly produce, but turning it into a good dining experience as well.

【題文1】What does the underlined words ＂edible food＂ in Paragraph 1 refer to?

A. Healthy food. B. Expensive food.

C. Food suitable to eat. D. Food grown locally.

【題文2】Why does the Salvage Supperclub have dinners inside the dumpsters?

A. To share their fancy ideas. B. To warn people not to waste.

C. To show waste should be reused. D. To advise people not to throw dumpsters.

【題文3】What’s Josh Treuhaft’s advice to reduce America’s food waste?

A. People should make full use of ugly food.

B. People should join in the ugly food movement.

C. People should be more aware of food shortage.

D. People should develop their potential in producing food.

【題文4】What makes Raley’s stop its ＂Real Good＂ after 90 days of its operation?

A. Lack of sources of product. B. Retailers’ pursuing larger profit.

C. Bad harvests due to bad weather. D. People’s unwillingness to buy imperfect produce.
