Climate change has caused a rise in sea levels.This has increased an amount of salt in fresh water used on farms near the sea.As a result farmers are unable to use fields close to the sea.Scientists call this process “salinization(盐碱化)”,which is reducing the world’s farm lands by 1 to 2 percent every year.

But a farmer in Holland,Marc Van Rijsselberghe started with an experiment,using a mixture of sea and fresh water to grow healthy and tasty vegetables.He put several kinds of plants in the fields.Mr.Van Rijsselberghe worked on the project with scientists from the Free University of Amsterdam.He divided a farm into eight areas.Every area was watered by different water.“We put in a lot of plants in the fields and then we put them in fresh water and in sea water with all the varieties(变化) between them,and then we saw which variety was surviving and which variety was dying.”A computer program created water with eight levels of salinity(盐度).Computerized measuring devices(测量仪器)controlled the water levels and the levels of salinity.

Mr.Van Rijsselberghe said he was able to harvest vegetables from most of the eight test areas.He said the vegetables were smaller than those grown in fresh water.But he said they had more sugar and salt,so they tasted better.

The farmer grew carrots,potatoes,cabbage and onions.He found that potatoes grew better than the other vegetables in the combination of sea and fresh water.Mr.Van Rijsselberghe said four kinds of these potatoes were recently sent to Pakistan,where thousands of hectares(公顷)of land have been damaged by salinization.Farmers in Pakistan will test the Dutch potatoes to see if they can be grown in those fields.

Many years ago，when I was fresh out of school and working in Denver，I was driving to my parents’ home in Missouri for Christmas. I stopped at a gas station about 50 miles from Oklahoma City，where I was planning to stop and visit a friend. While I was standing in line at the cash register(收款台)，I said hello to an older couple who were also paying for gas.

I took off，but had gone only a few miles when black smoke poured from the back of my car. I stopped and wondered what I should do. A car pulled up behind me. It was the couple I had spoken to at the gas station. They said they would take me to my friend’s. We chatted on the way into the city，and when I got out of the car，the husband gave me his business card.

I wrote him and his wife a thank?you note for helping me. Soon afterward，I received a Christmas present from them. Their note that came with it said that helping me had made their holidays meaningful.

Years later，I drove to a meeting in a nearby town in the morning. In late afternoon，I returned to my car and found that I’d left the lights on all day，and the battery(电池) was dead. Then I noticed that the Friendly Ford dealership—a shop selling cars—was right next door. I walked over and found two salesmen in the showroom. “Just how friendly is Friendly Ford？” I asked and explained my trouble. They quickly drove a pickup truck to my car and started it. They would accept no payment，so when I got home，I wrote them a note to say thanks. I received a letter back from one of the salesmen. No one had ever taken the time to write him and say thank you，and it meant a lot，he said.

“Thank you”—two powerful words. They’re easy to say and mean so much.

At the end of the president’s speech,1,200 school leaders attending the event signed the Future Ready District Pledge on their iPads.It promises the education leaders to help develop a culture of learning through technology at their schools,and to support teachers and students in using technology.

Most of the sandstorms that had swept China last year originated from foreign land,a Chinese official in charge of desertification control said Monday.And the invasions(入侵)could partly explain the frequent sandstorms in the country in recent years despite its achievements in desertification control.

Since the start of last spring,the north and northwestern Chinese regions had been hit by 17 sandstorms,of which,a dozen came from foreign land.

Situated in the central-Asia sandstorm region,one of the world’s four largest sandstorm sources,China also suffers from sandstorms from outside the country while being blamed as a sand source to northeast Asia.The other three major sources are in Africa,North America and Australia.

The land suffering from desertification has been decreasing by 7,585 sq.km annually in China,and the area of sandy land has also been falling by 1,284 sq.km a year.

The shrinkage(收缩)forms a clear contrast to the fact that the land suffering from desertification and sandy feature was added by 10,400 sq.km and 3,436 sq.km late last century,respectively.

Currently,the desertification land in China makes up 2.64 million sq.km,accounting for 27.46 percent of the nation’s land,and its sandy land totals 1.74 million sq.km,accounting for 18.1 percent of the country’s total.

1.What does the underlined word “decreasing” mean in Paragraph 4?

A.Going down. B.Going up.

C.Coming from. D.Taking up.

2.Where do most of the sandstorms in China come from?

A.The northern Chinese regions.

B.The northwestern Chinese regions.

C.Foreign countries.

D.The western part of China.

3.Which of the following is believed to be the sand source to northeast Asia?

A.China. B.Africa.

C.Mongolia. D.Australia.

4.From the passage,we can infer that .

A.the land in China suffering from desertification has been increasing greatly

C.the desertification land makes up nearly half of China’s territory

D.little progress has been made in controlling desertification in China

Everyone needs a break, and vacations are not meant for serious study. 1. The Spring Festival is coming up so this is the perfect time to discuss some great English language literature to take on a long train journey.

Before getting into the recommendations, you need to determine your English reading comprehension level. If you’re at the beginner level, there are two options: reading a children’s book or reading a book that you’ve read in Chinese translation. 2.If you’re at the intermediate level, popular books like pop fiction, mysteries and thrillers are good options. For advanced readers, classic works of literature or modern prize winners (Nobel, Pulitzer) are good options.

3. When I pick up a book I like, even though the first few chapters are really hard to get through, I would try to get accustomed to the language the author uses. Generally, after the first few chapters, things get a lot easier, especially if I get involved in the story.

Another great way to keep yourself motivated is to find a friend who’s interested in reading the same book. You can make goals that you both want to achieve. 4.

Some quick recommendations: Harry Potter, start with the first book and go on from there; the Narnia series; anything by US writer Michael Crichton; and if you like horror, US writer Stephen King is always unusual and fun. 5. Happy reading!

A. If you pick a book which is so challenging, it will be too stressful.

B. The most important thing is to pick a book that you’re really interested in.

C. You may also enjoy your reading when hanging out with your family.

D. You should just find a topic or author you’re interested in, and the rest will go from there.

E. You can also discuss plot lines or vocabulary issues with each other by SMS or e-mail.

F. Instead, they’re a great way to take a break and enjoy a good book.

G. This will help you get over any unfamiliar words or phrases, since you’re already familiar with the story.
