Have you ever missed something in your life?

The wife asked the husband when she was 25. Upset, the husband replied:“I missed a new job opportunity.”When she was 35,the husband angily told her that he had just missed the bus. At 45, the husband sadly said:“I missed the opportunity to see my relative before his last breath." At 55,the husband said disappointingly: “I missed a good chance to retire.” At 65, the husband hurriedly replied:“I missed a dental appointment.”At 75, the wife did not ask the husband any more, and the husband was kneeling in front of the very sick wife. Remembering the question the wife used to ask him, this time he asked the wife the same question. The wife, with a smile and peaceful look, replied: “In this life, I did not miss having you!" The husband was full of tears. He always thought that they could be together forever. He was always busy with work. So he had never been circumspect to his wife. The husband hugged the wife tightly and said: “Over 50 years, how 1 had allowed myself to miss your deep love for me !”

In the busy city life, there are many people who are always busy with work. These people focus on their jobs, and these people sacrifice all their time and health to meet the social expectations. They are unwilling to spend time on health care. They miss the opportunity to be with their children in their growing up. They neglect the loved ones who care for them, and also their health. Nobody knows what is going to happen one year from now.

Life is not permanent, so always live in the now. Express your gratitude to your loved ones in words. Show your care with actions. Treat everyday as the last day of life. In this way, when you are gone, your loved ones would have nothing to feel sorry about.

1.What did the husband miss when his wife was 65?

A.He missed the bus.

B.He missed a dental appointment.

C.He missed a good chance to retire.

D.' He missed the opportunity to see his relative.

2.The underlined word“circumspect" ( in Paragraph 2) is closest in meaning to“_____”.

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. 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 conducting 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 a reality," said Mark Ayre of the European Space Agency last month.

What seems like science fiction is not completely unlikely. 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 by the end of 2004.

A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.

"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 (新陈代谢) 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 shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.

According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的卫星) 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.

1.European researchers are conducting hibernation experiments to ________.

A. ensure astronauts to get a complete sleep　

B. find the secret of some creatures

C. make preparations for the journey to Jupiter’s moon Callisto

D. know if man can sleep for years

2.The sentence “What seems like science fiction is not completely unlikely” means ______.

A. Science fiction is people’s imagination.

B. Science fiction is imaginative, but it can be realized.

C. Things seem impossible may come true.

D. Things described in science fiction are sure to become true.

3.The passage implies that ________.

A. putting living cells into a sleep-like state is full of failure

B. Biggiogera is confident with the experiment

C. human’s hibernation needs no energy

D. medical research is the key to space flight hibernation system

4.What’s the best title for the passage?

A. Six humans to fly to Callisto　

B. Human hibernation improves health

C. Space travel attracts people　　

D. Deep sleep for deep space travel
