Have you ever dreamed of visiting a planet in the Milky Way? While the trip sounds exciting, it would take years and years to reach the place that we are going to. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.

European researchers are now doing hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. “If there was an effective technology, it could make deep-space travel come true,” said Mark Ayer of the European Space Agency last month.

What seems like science fiction is not completely impossible. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don’t age. They have now moved on to small, non-hibernating mammals like rats. The results will be out soon.

A major challenge is the fact that cells can be very simple systems, but body organs are far more complex(復(fù)雜的).

“It's like moving from a simple Apple computer to a supercomputer,” said Marco Biggiogera, a hibernation researcher at Italy’s University of Pavia.

Just like bears and frogs, the hibernation of human beings would cause a person’s metabolism (新陳代謝) to lower so they would need less energy.

Medical research, however, is just half of a space flight hibernation system.

There is the challenge of designing a suitable protective place to live. Such a place would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (監(jiān)控) life functions and serve the physiological needs of the hibernator.

According to Ayer, the six-person Human Outer Planets Exploration Mission to Jupiter’s moon (木星的衛(wèi)星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.

根據(jù)材料內(nèi)容選擇最佳答案, 將其標號填入題前括號內(nèi)。

There are different ways to store fish. One way to keep fish for future use is canning it. We’ll have this article describing, step by step, how to prepare dried fish.

Begin with fish that are out of the water. If the fish are small, leave their heads on. Cut off the heads if the fish are longer than twenty centimeters or weigh more than one hundred fifteen grams.

Now clean the freshly caught fish. Cut off the scales and cut open the stomach. Remove everything inside. Then wash the fish in clean water and fill salt into them.

Next, put the fish in a container with a solution (溶液) of three hundred grams of salt and one liter of water. This will remove the blood from the meat. Keep the fish in the saltwater for about thirty minutes. After that , wash them again in clean water.

Next, put the fish in a solution that has more salt in the water. The water should be salty enough so that the fish can float to the top. If the fish sink to the bottom of the container, add more salt to the water.

Cover the container with a clean piece of wood. Place a heavy stone on the wood to hold it down. Leave the fish there for about six hours.

After that, remove them from the saltwater and place them on a clean surface. Cover the fish with a clean piece of white cloth and let them dry.

根據(jù)短文內(nèi)容選擇最佳答案,并將其標號填入題前括號內(nèi)。

B. Cut off the heads if the fish are very small.

D. Leave all the heads of the fishes on.

3.What is the solution of salt and water for?

A. To make the fish clean and dry.

B. To make the meat more delicious.

C. To keep the meat fresh.

D. To remove the blood from the fish.

4.If the solution is not salty enough, __________________.

A. The fish can not float to the top.

B. The fish can float to the top.

C. The fish will dry.
