A

Children are hooked on computers. Some spend up to six hours a day on their gadgets（小游戏）. They can be playing games live with others elsewhere in the world, updating their status on social media, texting friends or looking for the latest app to download to their tablets or smart phones.

This worried Martin Strott, headmaster of the Old Hall School in Wellington, in the west of England. He was so concerned that he challenged his students to take part in a week of ‘digital detox（戒瘾诊所）’. Strott told the local newspaper, the Shropshire Star, that he encourages the pupils to have a good knowledge of the computer from a young age, but is concerned that too much screen time will affect the development of their social skills. He said that this over-reliance on digital devices erodes（侵蚀）family time and they’re missing out on messages from body language and facial expressions from those around them”.

According to the headmaster, the parents are happy with the movement. But what about the children? Nine-year-old Fred usually spends around two hours on his gadgets at home after school and around 12 hours on weekends. For him, the digital detox experience was “really hard”. Fred spent it playing outside, especially basketball. He said that he’ll probably engage in different activities from now on but he did miss his phone and online games.

The idea of keeping children away from their tech for a while to prevent ‘addiction’ is not particularly new. There have been similar movements in the US. But are they effective in the long run? Well, even if kids go back to their gadgets, the hope is that at least they’ll think about how they use their time.

B

The government of Norway is planning to build an unusual storage center on an island in the Arctic Ocean. The place would be large enough to hold about two million seeds. The goal is to present all crops known to scientists. The British magazine New Scientist published details of the plan last month. The structure will be designed to protect the world’s food supply against nuclear war, climate change and other possible threats. It will be built in a mountain on the Norwegian

邢台二中题库英语必修三单元检测出题人：康丽艳审核人：王晨island of Spitsbergen. The mountain is less than one thousand kilometers from the North Pole, the northernmost position on earth.

An international group called the Global Crop Diversity Trust is working on the project. The director of the group, Cary Fowler, spoke to New Scientist. He said the project would let the world rebuild agriculture if, in his word, “the world came to the worst”. Norway is expected to start work next year. The project is expected to cost three million dollars. Workers will drill（钻孔）deep in the side of a sandstone mountain. Temperatures in the area never rise above 0ºC. The seeds will be protected behind walls a meter thick and high-security door.

The magazine report says the collection will represent the products of ten thousand years of farming. Most of the seeds at first will come from collections at seed banks in Africa, Asia and Latin America. To last a long time, seeds need to be kept in very low temperatures. Workers will not be present all the time. But they plan to replace the air inside the storage space each winter. Winter temperatures on the island are about eighteen degrees below 0ºC. The cold weather would protect the seeds even if the air could not be replaced.

Mr. Fowler says the proposed structure will be the world’s safest gene bank. He says the plant seeds would only be used when all other seeds are gone for some reason. Norway first put forward the idea in the 1980s. But safety concerns delayed the plan. At that time, the Soviet Union（苏联）was meeting in Rome of the Food and Agriculture Organization.

A．increase the world’s food output in the future

B．carry out some scientific experiments on plant genes

C．build an exhibition centre of the world’s plant seeds

D．protect crop seeds from dying out in case of possible disasters

6．Which of the following statements is TRUE according to the above passage?

A．The government of Norway will perform the project alone.

B．Seeds to be collected there were produced ten thousand years ago.

C．Spitsbergen is chosen because it is free of the nuclear war forever.
