Entering Space, astronauts can give us a fascinating account of a shuttle flight, describing the pressure of a countdown and launch, the complexities of living the days in the strange weightless environment, the challenges of working in space, the emotional effect of seeing earth from space, the drama of the meteoric landing.

However, there are also plenty of things that astronauts can’t do because of their weightless environment, and that’s very sad. What’s more, they can’t even let their sadness show, because it’s impossible to cry in zero gravity.

Of course, astronauts can still produce tears. But crying is much more difficult in space, reported The Atlantic in January. Without gravity, tears don’t flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go – they just stick to your eyes.

In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks. “Tears,” he said, “don’t fall off of your eye... They just kind of stay there.”

Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes. But that’s not the case in space. The space environment dries out astronauts’ eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. “My right eye is painful like crazy.” Feustel told his teammate during the walk.

Since gravity doesn’t work in space, astronauts need some extra help to get rid of the tears. Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait – “When the tears get big enough they simply break free of the eye and float around,” astronaut Ron Parise told The Atlantic.

There are lots of small things – things like crying – that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment, like space. There, astronauts can’t talk to each other directly. They also can’t eat or drink in normal ways. They can’t even burp (打嗝), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up (嘔吐) everything in their stomach, according to the UK National Space Center.

Thus, perhaps it’s only space explorers who can honestly say: “Gravity, you’re the best.”

If you could take a large snapshot (照片) of everyone in the United States today, it would contain six million more females than males. In this country, women outlive men by about seven years. Throughout the modern world, cultures are different, diets are different, ways of life and causes of death are different, but one thing is the same--- women outlive men.

It starts before birth. At conception, male fetuses(胎兒) outnumber female by about 110 to 100; at birth, the rate has already fallen to about 105 boys to every 100 girls. By the age of 30, there are only enough men left to match the number of women. Then women start taking a lead. Beyond the age of 80, there are nearly twice as many women as men.

“If you look at the top ten or twelve causes of death,” said Deborah Wingard, a disease expert at the University of California at San Diego, “every single one kills more men.” She listed out one sad fate after another – heart disease, lung cancer and so on. Each kills men at roughly twice the rate of that it does women.

More than a century ago American men surpassed and outlived the women. But in the 20th century, women began living longer, primarily because pregnancy（懷孕) and giving birth to children had become less dangerous. The gap grew steadily. In 1946, for the first time ever in the United States, females outnumbered males.

Parts of the reasons are self-made. Men smoke more, drink more and take more life-threatening chances than women. Men are murdered (usually by other men) three times as often as women are. They commit suicide at a higher rate and have more than twice as many fatal car accidents as women do. Men are likely to be involved in alcohol-related deaths.

But behavior doesn’t explain away the longevity gap.

Today, some scientists studying the gender gap believe that the data point to one conclusion: Mother Nature may be partial(偏袒) to women.

Every living thing is assembled according to instructions on its chromosomes (染色體), and humans have 23 pairs of them. But in males, one of these is a weak non-matching pair, expressed by “xy”. The agreement pair in females is “xx”, and its genetic “backup” power is sometimes listed as a clue to woman’s superior restoring force. If the male’s single “x” chromosome isn’t perfect, it is possible for a serious genetic disorder to appear. Some blood diseases, for instance, are diseases caused by a shortcoming in a single gene on the “x” chromosome. They are far more common in males than females.

1.What may the underlined word “outlive” in Paragraph1 mean?

A. Become stronger than.

B. Live longer than.

C. Be wiser than.

D. Be born more earlier than.

2. What can we infer from the second paragraph?

A. Female fetuses are more than male.

B. The female are surpassing the male with age increasing.

C. By the age of 30, the female are more than the male.

D. Over 90, men are more than women in the United States.

3.How many exact diseases are mentioned as examples killing twice men than women?

A. Two. B. Three. C. Ten. D. Five.

4.The best title for this passage is _____

A. Why women live longer than men

B. Women are different from men

C. American men once lived longer than the women

D. Men smoke and drank more than women

When computer salesman Li Guang and his girlfriend Huang Minxia saw on TV the destruction caused by the unexpected earthquake,they quickly filled their car with bottled water and instant noodles and drove more than 160 miles to lend a hand.

“It’s a small car,but we just wanted to help,” said Li,from Chongqing,a city next to the hardest-hit Sichuan province.

Donations (捐贈(zèng)) are flooding in,more money than charities (慈善) in China collected all of last year,and so are volunteers.

In the week since the quake,donations have totaled $1.3 billion—85 percent raised within China.

Many,like Li,are taking advantage of growing private car ownership and a new,expanding highway system to join the line of government and army assistance toward the epicenter.

Across the disaster region,thousands of cars decorated with large handwritten signs—“Hardship comes from one direction,help comes from everywhere” and “For the people,for the Beijing Olympics”—were coming from as far as the capital,Beijing,more than 900 miles away.

Private cars crowded so thickly on roads that the police set up donation drop-off points outside cities and towns to clear the way for army and government assistance.People living in tents along the roads posted handwritten signs asking for urgently needed items—water,rice,vegetables.Cars paused to hand out a box or two and then drove on.

Instead of waiting for government-organized charity drives,people quickly acted on their own.Bank account (銀行賬戶) numbers for making earthquake donations flashed on Web logs and mobile phones.Blood donation centers were overwhelmed (使應(yīng)接不暇) by offers and began asking citizens to register (登記) in advance.

“People are really united this time,and they’re acting on their own without waiting to be asked.It sounds corny,but we’re taught in schools and from our parents about helping others,” said Ge Jian,the company’s general manager.

1.What did Li Guang and his girlfriend Huang Minxia intend to do soon after the earthquake?( )

A.They intended to help the victims in the quake-hit areas.

B.They were on the way to a pleasant journey in Sichuan.

C.They were told to do something for the disaster.

D.They wanted to find their friends in the epicenter.

2.What does the underlined word “corny” most probably mean?( )

A.Out of date. B.Heart-broken.

C.Funny. D.Disappointing.

3.According to the passage,all the following statements are true EXCEPT .

A.The good road system made it possible for more private car owners to rush to help.

B.The local people in the quake zone were short of food and drinks.

C.More money was collected from overseas than within China for the earthquake.

D.People across China were taking active part in the rescue work.

4.Why did Blood donation centers advise people to register ahead of time?( )

A.Because they were expecting more money rather than blood.

B.Because they had collected enough blood for the disaster.

C.Because they were ready to go to the epicenter and they were much too busy.

D.Because too many people were offering to donate blood.
