【题目】Farming is moving indoors,where the sun never shines,where rainfall is irrelevant and where the climate is always right.The perfect crop field could be inside a windowless building with controlled light,temperature,wetness,air quality and nutrition.It could be in a New York highrise or a sprawling complex in the Saudi desert.It may be an answer to the world's food problems.

The world already is having trouble feeding itself.Half the people on Earth live in cities,and nearly half of those- about 3 billion-are hungry or illfed.Foodprices,currently increasing,are buffeted by dryness,floods and the cost of energy required to plant,harvestand transport.And prices will only get more unstable.Climate change makes longterm crop planning uncertain.Farmers in many parts of the world already are using water available to the last drop.And the world is getting more crowded:by midcentury,the global population will grow from 6.8 billion to 9 billion.

To feed so many people may require expanding farmland at the expense of forests and wilderness,or finding ways to completely increase crop output.

Gertjan Meeuws has taken the concept of a greenhouse a step further,growing vegetables and house plants in enclosed (封闭的) and regulated environments.In their research station,water flows into the pans when needed,and the temperature is kept constant.Lights go on and off,creating similar day and night,but according to the rhythm of the plant.

A building of 100 square meters and layers () of plants could provide a daily diet of 200 grams of fresh fruit and vegetables to the entire population of Den Bosch,about 140,000 people.Their idea isn't to grow foods that require much space,like corn or potatoes.

Here sunlight is not only unnecessary but can be harmful.Plants need only specific wavelengths of light to grow.Their growth rate is three times faster than under greenhouse conditions.They use about 90 percent less water than outdoor agriculture.And city farming means producing food near the consumer,and there's no need to transport it long distances.

1What can we mainly learn from Paragraph 2?

A. The climate is worse and worse.

B. The city people live a hard life.

C. The world has difficulty feeding its people.

D. The world's population is increasing fast.

2Which of the following is true of the environments in the research station?

A. The temperature is often changed.

B. Sunshine is in great need for plants.

C. Day and night depends on plants.

D. Air quality is controlled by plants.

3It can be inferred from the text that Gertjan Meeuws's farming________.

A. helps save sea water a lot

B. is highly adaptable

C. resembles greenhouse agriculture

D. suits the production of corn

4What is the text mainly about?

A. Development of indoor farming.

B. Great Revolution in farming.

C. Advantages of indoor farming.

D. Sunless,rainless indoor farming.

【题目】阅读理解。

A lot of us lose life’s tough battles by starting a frontal attack—when a touch of humor might well enable us to win.Consider the case of a young friend of mine,who hit a traffic jam on his way to work shortly after receiving an ultimatum about being late on the job.Although there was a good reason for Sam’s a being late—serious illness at home—he decided that this by-now-familiar excuse wouldn’t work any longer.His supervisor was probably already pacing up and down preparing a dismissal speech.

Yes,the boss was.Sam entered the office at 9:35.The place was as quiet as a locker room;everyone was hard at work.Sam’s supervisor came up to him.Suddenly,Sam forced a grin and stretched out his hand.“How do you do!” he said.“I’m Sam Maynard.I’m applying for a job,which,I understand,became available just 35 minutes ago.Does the early bird get the worm?”

The room exploded in laughter.The supervisor clamped off a smile and walked back to his office.Sam Maynard had saved his job—with the only tool that could win,a laugh.

Humor is a most effective,yet frequently neglected,means of handling the difficult situations in our lives.It can be used for patching up differences,apologizing,saying “no”,criticizing,getting the other fellow to do what you want without his losing face.For some jobs,it’s the only tool that can succeed.It is a way to discuss subjects so sensitive that serious dialog may start a quarrel.For example,many believe that comedians on television are doing more today for racial and religious tolerance than people in any other forum.

【1】Why was Sam late for his job?

A.Because he was ill.

B.Because he got up late.

C.Because he was caught in a traffic jam.

D.He was busy applying for a new job.

【2】The main idea of this passage is ________.

A.Sam Maynard saved his job with humor

B.humor is important in our lives

C.early bird gets the worm

D.humor can solve racial discriminations

【3】The phrase clamped off in Paragraph 3 means ________.

A.tried to hold back B.tried to set

C.charged D.gave out

【4】Which of the following statements can we infer from the passage?

A.Many lose life’s battles for they are lacking in a sense of humor.

B.It wasn’t the first time that Sam came late for his work.

C.Sam was supposed to come to his office at 8:30.

D.Humor is the most effective way of solving problems.

【题目】In the wild, lions tend to pick on the animals that are weak, old, sick or hurt. Even with the strength of their numbers they will go after the easy prey(捕猎).

The lions picked their prey of choice for this poor Gazelle. The Gazelle, surrounded by lions, looks as if she were crying when the camera closed up on her face.

The lions were faster than the Gazelle, and my goodness they were smart. When the lions got close enough to the Gazelle, even while running at speed, they would trip the running animal.

This Gazelle was moving. When pressure came from a different angle she changed directions. When she could feel the breath of the lions on her neck she changed direction. When they tried to trip her, stop her, trick her, block her, she changed direction. She ran until they stopped chasing after her. It was pointless to the lions. This Gazelle had purpose. She was running for her life.

I do not care what, who, when, where, or how often life tries to take you down a path you have not intended to go. If you feel the pressure and things are not going the way they should, change direction.

【题目】More than 30,000 people went to the White House on Monday for the 136th Easter Egg Roll (复活节滚彩蛋). President Barack Obama and First Lady Michelle Obama held the event by inviting thousands of kids to color and look for eggs. The theme of the day was “Hop Into Healthy, Swing Into Shape.” It was part of the First Lady’s “Let’s Move!” program to reduce obesity rates (肥胖率) among American kids. Mrs. Obama spoke to young reporters about her goal to get children to eat right and keep moving.

“We are working to make sure that kids born today grow up healthy, learn how to have balanced meals, and get more physical activity into their lives,” she said.

Mrs. Obama said she wants children across the nation to understand that “exercise isn’t just hard work, it’s play. If you’re running around with your dog, you’re getting exercise. If you walk up the stairs, that’s exercise. But if you’re sitting in front of the TV or on a computer game, you’re not exercising.”

The First Lady said that for kids who have balanced meals most of the time, having a special snack, like chocolate, will not hurt. “And if you are active, you can splurge (挥霍) a little more,” she said. Mrs. Obama’s favorite “splurge food” is French fries. But she balances her splurging by exercising almost every day. She loves to play tennis and she practices yoga.

“A lot of kids look up to athletes, and I think it’s important for athletes to share their good habits,” Mrs. Obama said. “Kids aren’t just going to wake up and be LeBron James. He’s practicing and eating right and working out and training. Our athletes can be really good messengers to kids who look up to them — they can say to kids, ‘If you really want to be like me, then you really do need to eat your vegetables.’”

1The purpose of the “Let’s Move!” program is to _____.

A. help kids keep healthy

B. train more young reporters

C. encourage kids to eat more eggs

D. invite kids to visit the White House

2In Mrs. Obama’s opinion, exercise _____.

A. can be fun to do

B. means hard work

C. should be done outdoors

D. requires special equipment

3“Splurge food” is allowed to be eaten when _____.

A. you don’t hurt yourself

B. you have a special snack

C. you never eat French fries

D. you eat right and stay active

4What can we learn from the last paragraph?

A. All kids want to be LeBron James.

B. It is very easy to form good habits.

C. Athletes can set a good example for kids.

D. Kids like the messages the athletes give them.

5In which part of a newspaper will the text most probably appear?

A. Business. B. Health.

C. Culture. D. Education.
