He then showed the policeman that he copied in his notebook. It was read: “One-way street”.

【题目】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 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 worst 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 0C. 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 0C. 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 was meeting in Rome of the Food and Agriculture Organization.

【题目】Is there something that you’ve always wanted to try but just never had the time？Well, make plans to try it now since you are on summer vacation. Not all vacations call for taking a tour bus to take photos of famous landmarks. Some vacations allow you plenty of opportunities to learn.

The most difficult aspect of a learning vacation may be choosing one because the possibilities are endless. If you enjoy cooking，various companies can take you to Italy, France, Spain, Mexico or even Peru. Once there, you can learn to prepare the local cuisine(烹饪). Trips are often planned to fit in with local food festivals or special events.

The term “learning vacation” often brings language to mind. The best way to learn a language is in an environment where it’s spoken. Study Spanish, French or English. Or attempt a more unusual language like Polish, Estonian or Thai. You’ll be able to learn about the country and absorb the culture at the same time. In that case, you can really learn the authentic foreign language.

If you are fond of sports, you can polish your skills or learn new ones. Golf and tennis schools welcome players of all levels. If you want a bigger thrill, you can learn to surf, go climbing or race cars. It’s even possible to learn the art and techniques of bull fighting while on vacation!

You can also discover your inner artist. Many places offer painting classes in different mediums. The scenic locations of the schools offer plenty of subjects that provide inspiration for practice.

If you prefer capturing the world on film, take a photography vacation. Travel with a small group to photograph beautiful animals or scenery. You can also practice your technique on people or at historical sights.

Once you decide on a vacation, choose a company carefully. Request names of recent customers you can contact, and then ask them for an evaluation. The more you know before you go, the better prepared you’ll be. Then go out and learn something!

【1】Why is it hard for you to decide on a learning vacation?
