Imagine a perfect day: the weather is good and everything seems fine. When, suddenly, your mobile phone loses its signal, the television has no programs, and you can’t get online with your computer.

What has happened? These are just the types of problems a solar storm（太阳风暴）might cause. You may not think of storms as putting our society in danger. But today, a solar storm is as serious as other bad events, such as earthquakes.

A solar storm is caused by solar flares（太阳耀斑）: large explosions（爆炸) near the sun that can give off lots of energy. The strong energy can stop the satellite systems（卫星系统）that control our computers, telecom networks and so on. These storms can even cause the power to go out for weeks or months.

In the past of months, scientists have recorded some of the strongest sun flares in years. The most recent one happened around Valentine's Day, 2011. It caused radio and satellite signals to go down in some northern cities in China.

“Solar Flare activity is going to be much worse than what we’ve seen in the past. We’re not talking about a few cities losing power. It could be half of the country, maybe more.” SolarStormWarning. com, a US website about space weather, warned.

Scientists say that little can be done to predict such a storm. Governments around the world are trying to work together before the next storm, although they are not sure when that may happen.

1.According to the passage, a solar storm can cause many problems EXCEPT that________.

A.earthquakes happen B.mobile phones have no signals

C.people cannot get online D.the power may go out

2.According to the passage, solar flares are________.

A.telecom networks B.solar storms

3.From the passage, the right order of the following is________.

a. solar flares give off lots of energy　　　 b. people can’t get online with their computers

c. solar storms happen　　　　　　　　　　 d. satellite systems are stopped

A.a-b-c-d B.a-c-d-b C.c-a-b-d D.c-b-a-d

4.The writer wrote the passage mainly to________.

A.call for scientists to predict when the next solar storm will happen

B.tell people how to solve the problems caused by solar storms

C.introduce what solar storms are to people

3D printing is becoming more and more popular. We are now able to print things such as clothing, prosthetic limbs(假肢), musical instruments(乐器) and so on. People and businesses are able to create the things they need very quickly and easily using 3D printers.

But can you imagine printing food? Some scientists are trying to revolutionize our eating experience by doing this. They hope that having a 3D printer in the kitchen will become as usual as the microwave or blender. Scientists say that they are easy to use: You simply have to choose a recipe and put the food “inks” into the printer. You can also change the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create delicious meals.

Using 3D printers to create your meals would also be saving the environment. There would be less need for traditional growing, transporting(运输) and packaging as food production would be quicker and easier.

Printing food could also help people who suffer from dysphasia(吞咽障碍症). They could program(为……编程) the printer to print softer versions of their favorite foods so that they would not have trouble eating them.

However, some people think that the future of 3D ­printed food would be a disaster. It could take away many jobs, including those for growing, transporting and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes could be printed from a raw “food ink”. Similarly, traditional cafes and restaurants might lose business. Also, there are worries about the printed food: Is it really possible to get the nutrients(营养物) we need from food­based inks and gels?

What's more, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the fun of cooking is dead and meals can be done at the touch of a button.

1.What should we do first if we want to print food?

A.Choose a recipe. B.Program the printer.

C.Change the instructions. D.Put food “inks” into the printer.

2.What does the underlined word “revolutionize” in Paragraph 2 probably mean?

A.Remember clearly. B.Take seriously.

C.Change completely. D.Teach carefully.

3.Which could be the advantage(好处) of 3D food printing?

A.Saving the environment. B.Giving people nutrients.

C.Helping with traditional farming. D.Offering more job chances.

4.Which is the best title for　 the passage?

A.Why is 3D printing so popular? B.Will 3D printing be the future of food?

C.3D Food Printers in the Kitchens D.Different Opinions on 3D Printing

English is becoming more and more popular in China. It can be used in every field, such as on some signs and restaurant menus. But there are some problems when people use it. Perhaps you've seen the English letters “WC” in your city. They show public toilets. But do you know it is far from native(地道的) English? In fact, foreigners from English­speaking countries seldom use the letters.

Workers in our city are changing “WC” signs all over the city. The government is spending much money changing all the bad English on signs and restaurant menus. Many other places in China are following our pace．

“WC, or water closet, is old­fashioned English. It sounds dirty to me.” says Nancy, a young woman from the US. The old sign will become “Gents/Men”and “Ladies/Women”．“I see much poor English in everyday life, and not only on signs，” she says, “I know what they mean, but they are Chinglish, not real English. For example, when someone says to me ‘My hometown is Guizhou Province', I know he or she should say ‘My hometown is in Guizhou Province'. Hometown is a smaller place in a province.” The common mistakes that Nancy picked up include “Not Entry”， which should be “No Entry”， “Direction of Airport” should be changed to “To the Airport”. And it is “Room Rate”， not “Room Price”. And remember to “Keep off the Grass” rather than “Care of the Green”．

The next time you walk on the street or eat in the restaurant, you can go and see if the expressions are right.

1.Who seldom uses letters of “WC” according to the passage?

A.Chinese students.

B.Foreigners from other countries.

C.Teachers in China.

D.English­speaking foreigners.

2.What's the attitude(态度) of the government towards the bad English on signs?

A.It's native.

B.It should be changed.

C.It doesn't matter.

D.It can be used on signs.

3.What does the underlined word “pace” mean in this passage?

A.steps B.habits C.chances D.dreams

4.Which of the following signs is Right?

A.Not Entry B.Room Price

C.To the Airport D.Care of the Green

5.What is the main idea of the passage?

A.Chinglish on menus.

B.Money spent on Chinglish.

C.Usages of native English.

D.Letters of “WC”．
