【題目】Forest are amazing and so are the animals that live in them. We enjoy watching TV shows about bears, bats or monkeys. We know a lot about their lives: how they find food or what they do at different times of the year. But what about smaller animals that are more difficult to see or film?

Many small animals that live in forests are very important for the soil. A French scientist, Francois Xavier Joly, is studying one of them — the millipede(千足蟲(chóng)).

The importance of leaves

When the leaves begin to die in fall, they turn from green to yellow and fall from the trees. As they decompose on the ground, nutrients(營(yíng)養(yǎng)物質(zhì)) are returned to the soil and carbon dioxide to the air. Life in the forest needs these nutrients. Without them, plants could not grow and there would be no food for animals such as the millipede.

Food on the forest floor

Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to be broken down than others. Sometimes it takes years. So what happens to these? This is where the millipede can help.

More on the menu

The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind. This is how the millipede turns dead leaves into food for others and helps life continue.

So next time you are walking through a forest, remember that something may be having a meal right under your feet.

【1】According to the passage, what can we learn about the millipede?

A. It can often be seen on TV shows.

B. It mostly feeds on the nutrients in the soil.

C. It is too small to be noticed by people.

D. It lives under mushrooms in the forest.

【2】What does the underlined word "decompose" in Paragraph 3 mean?

A. Break down.

B. Dry up.

C. Dig in.

D. Make out.

【3】What does the author want to tell us by mentioning mushrooms?

A. The millipede eats mushrooms in the forest.

B. The millipede helps to provide food for mushrooms.

C. Mushrooms play an important part in helping millipedes out.

D. Mushrooms decide what types of leaves the millipede will eat.

【4】According to the author, the millipede is ________.

A. poisonous

B. rare

C. unimportant

D. amazing

【答案】

【1】C

【2】A

【3】B

【4】D

【解析】文章介紹森林里的一種小生物，對(duì)森林土壤非常重要的千足蟲(chóng)。

【1】推理判斷題。根據(jù)文章第一段的句子But what about smaller animals that are more difficult to see or film?但是那些很難被看到或者被拍到的更小動(dòng)物呢？下文舉了千足蟲(chóng)的例子，可知千足蟲(chóng)太小了以至于不容易被人們看到。故選C。

【2】詞義猜測(cè)題。本段說(shuō)到，秋天樹(shù)葉變黃，從樹(shù)上落下來(lái)。這里當(dāng)它們?cè)诘孛嫔?/span>decompose，營(yíng)養(yǎng)物質(zhì)回到土壤里。以及結(jié)合下文This means that some leaves take much longer to be broken down than others.可知這里decompose的意思是“Break down分解”，故選A。

【3】細(xì)節(jié)理解題。根據(jù)文章倒數(shù)第二段的內(nèi)容But when it has finished, it produces waste.This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types but when they eat waste, they will eat any kind.千足蟲(chóng)吃完樹(shù)葉會(huì)產(chǎn)生糞便。這種糞便成為了mushrooms的食物，當(dāng)mushrooms吃樹(shù)葉時(shí)，它們選擇特定的類型，但是當(dāng)它們吃糞便時(shí)，任何種類都可以。可知文章提到mushrooms，是為了說(shuō)明千足蟲(chóng)給mushrooms提供食物。故選B。

【4】推理判斷題。根據(jù)文章第一句Forest are amazing and so are the animals that live in them.森林“amazing”，住在森林里的動(dòng)物也很“amazing”。下文作者介紹了森林中很重要的小動(dòng)物—千足蟲(chóng)，可推斷，在作者看來(lái)，千足蟲(chóng)是很“amazing”的生物。故選D。

【題目】For the Travel section, writers and editors selected special items to profile from a dozen cities.

Brussels: Chocolate.

Nearly half the chocolate consumed in the world is eaten in Europe, and Belgium—with average consumption of 14.99 pounds per person a year—certainly covers its fair share. While Brussels, the country’s capital, is home to hundreds of chocolate makers, what makes a visit necessary is the rich heritage of traditional chocolate makers.

Budapest: Paprika(紅辣椒)

The job of preparing Hungarian paprika was once considered too dangerous for mothers to do. A woman who touched her children upon returning from work risked burning them, so only the elderly and unmarried were allowed the delicate task of separating the skin from the flesh. But by the early 20th century, sweeter varieties and a machine turned paprika into a common feature of all Hungarian cuisine.

Lisbon: Tiles(瓷磚)

Is there a bluer country than Portugal? The blue sky and Atlantic Ocean embrace the land. The blue moods of Fado, the dark folk music, form the national soundtrack. And all across Portugal, the typically—blue designs of azulejos—ceramic tiles—are spread across churches, castles, palaces, university halls, parks. The result is a beautiful land of Christian saints, Portuguese kings, historical glories, aristocrats(貴族) at leisure, seascapes and so on.

Madrid: Guitars

Walking into one the Madrid’s storied guitar makers’ workshops can feel like stepping into the past. Curly wood shavings, from the palest pine to ebony, fall onto the floor as artisans(工匠) turn some humble wood into works of art. It’s painstaking work—all done by hand—with classical guitar models and the methods of making them changing little over the last century.

【1】What does the job of preparing Hungarian paprika suggest?

A. The popularity of Hungarian peppers.

B. The difficult of processing peppers.

C. The unique tradition in Budapest.

D. The hot level of Hungarian peppers.

【2】Which city can be a splendid setting for a film?

A. Brussels.B. Budapest.C. Lisbon. D. Madrid.

【3】What’s the similarity of the four items?

A. They’re all treasures of a city.

B. They all date back several centuries.

C. Their production processes are all painstaking.

D. They all win popularity in most European countries.

【題目】I recently ran into an old friend who I hadn't seen for two years. She looked tired and was talking in a loud voice. She is a headhunter, and had just finished interviewing a candidate but failed to impress him.

Then she started to complain about her health problems. One year ago, she began to notice a ringing in her ears. She went to the hospital and was told that her problem might have resulted from stress. The doctor gave her pills for her nerves.

At night, she has to listen to loud music to quiet the noise in her head and fall asleep. Her life has become a twopoint routine of work and home. Even while she was vacationing in Thailand, she found herself searching for the right candidate.

She suffers from the same workaholic depression as another friend who works for an advertising company. This friend has to work overtime almost every day. If she's lucky, she can leave at 9 p．m.; otherwise it's midnight. For her, working on weekends has become normal. Each time I see her, she seems down.

My two friends share something in common: They don't want to escape their misery, believing that if you don't work hard when you are young, you will regret it. That may be true, but there are limits. If every day you wake up feeling down, then it may be time to move on.

As important as finding a job that you really like, is finding a company with a healthy atmosphere. The right company should lift your spirits and have a team working toward a common goal. As for the employees, they should work hard and play hard. If you can enjoy life, you will have more passion to bring to your work.

【題目】On the day of college graduation, I told my friends and family the news:I was leaving the country I had lived in since childhood. “I just need a change,”I told them, but there was more. I was running from heartbreak. My relationship with the United States is the toughest one I have ever had, as a country I loved and believed in did not love me back.

Back in the 90’s, my mother brought me from our home in the Caribbean islands to the U.S.when I was 4 years old. She worked as a live-in nanny(保姆)for two years, playing mommy for white kids whose parents had better things to do. She didn’t believe that nanny meant maid, and did whatever was asked of her. She was thirsty to embrace her American dream, hoping that her children would be educated and she might have nannies of her own.

Those were our path to get a “good education.”When the neighborhoods with quality schools became too expensive for my mom to afford as a single parent, we went across the United States with Great Schools. net as our compass: New Jersey, elementary school; Texas, middle school; Florida, high school; New York City, private university

For a long time I survived by covering myself in all kinds of labels so that people would ignore the color of my skin, yet I existed on the edge of ugly, ignorant and uncultured. “Black people don’t really know how to swim, “a white lady told me when I worked as a swim instructor at my neighborhood’s pool. “The black children don’t like to read very much, “I overheard one librarian discussing with another while l sat down reading a book a couple feet away.

I was never able to make America my home. When I stripped myself of the labels painfully one by one, beneath them there is a wounded colored woman who refuses to be faceless anymore. My face may be disgusting to some since it bears proof that race continues to be a problem. My hope is that it will force Americans to re-examine their “post-racial” beliefs.

【1】What was the real reason that made the author leave the United States?

A. It couldn’t provide her with good education.

B. She just needed a challenge in her way of life.

C. The way she was treated there broke her heart.

D. She was tired of living in a strange country.

【2】What can we infer about the author’s mother from Paragraphs 2 and 3 ?

A. She sacrificed a lot to live a better life in America.

B. She was quite content to work as a live-in nanny.

C. She was particular about the schools her daughter attended.

D. She liked visiting all kinds of schools with the author.

【3】The author gives two examples in Paragraph 4 to show that_____ .

A. how ignorant and uncultured many people are in US

B. she needed to cover herself in all kinds of labels

C. the race problem is still serious in the United States

D. black children often have no interest in reading books

【4】The author’s attitude towards the United States on race problem is_____ .

A. supportive

B. positive

C. neutral

D. negative

We all wish we had just a bit more time. Just think what you could do with an extra hour or two each day: you could finally stick to an exercise routine, or spring-clean the house, or write your novel, or learn the guitar and so on.

____【1】__ But I can help you find more hours in your day for the things that really matter.

Get Out of Bed Earlier

If you normally get up at 7:30 am, try getting up at 7:00 am．That half-hour might not sound like much, but it could be time that you use to exercise, to read that book you've been meaning to finish. ____【2】_______

Do the Important Tasks First

Once you get to work, get the important ones done first （not the easy ones, or even the urgent（緊急的） ones）. You can afford to spend at least an hour working on big, important tasks rather than on all those little urgent ones.

_____【3】_____ The urgent tasks will still get done, and you won't miss the important ones.

Reduce Interruptions

If colleagues have a habit of hanging around your desk to chat, or if the phone is constantly ringing, you might find that it takes you half the day to finish a simple task like writing a letter. Constant interruptions don't just eat up time, they also break your concentration.

When you've got a big task to focus on, let your calls go to voicemail．______【4】_____ Wearing headphones makes it less likely that people will try to strike up a conversation．

_____【5】_____

A few minutes chatting, browsing the web, and so on, can easily turn into hours of wasted time over the course of a day.

When you’re working, work. If your concentration is slipping, take a proper break, go and get a glass of water, or stretch your legs a bit. And if you’re facing a difficult task, try breaking it into small steps or stages so that it’s easier to deal with.

A. Stay Focused On Your Work.

B. Take Breaks When Necessary.

C. If you have an office door, close it.

D. If you work like this, you’ll usually save time.
