Before astronauts can go into space, they have to have the right suit. That’s why NASA（美國(guó)國(guó)家航天和航空局）scientists are developing a new kind of space suit——lighter and more flexible than before. These new space suits will have lots of mobility(靈活性) for the astronauts, but will not need much maintenance. NASA wants the suits to include new technology that can help astronauts be safe in outer space.
Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.
“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.
Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.
These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(證明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.
1. What characteristic does the new space suit have?
A. The new space suit will need much maintenance.
B. The new space suit will be heavier than before.
C. The new space suit will have less mobility than before.
D. The new suit will use new technology to help astronauts be safe in outer space.
2.What’s the disadvantage of the Russian space suit?
A. The Russian space suit is big and massive.
B. The Russian space suit is much complicated.
C. The Russian space suit is merely used a few times.
D. The Russian space suit is easy to work in for long periods of time.
3.The underlined word “shield” in the third paragraph might mean_______.
A. harm B. protect C. help D. warn
4.Why can scientists test the design out before actually making the new space suits?
A. Because designing the new space suit is not a complex task.
B. Because computers are being used to help scientists design the new space suits.
C. Because it needs little knowledge to design the new space suits.
D. Because the scientists only change the old space suits a little and make them into the new ones.
5.How long will it take scientists to put the new space suits from prototypes into the first practical use?
A. Two years. B. Three years. C. Four years. D. Six years.
The ocean contains many strange and surprising creatures. One such creature is the puffer fish. This very strange fish is probably the most poisonous creature in the ocean. The poison that this fish produces is 275 times more poisonous than the chemical which is usually used to kill rats.
The puffer fish gets its name from the way the fish protects itself from enemies. Whenever it is attacked, the fish blows up its body to three times bigger than its normal size!
Another strange thing about this fish is the fact that it can swim like other fish. Because it does not have bones like oth
er fish, the puffer fish can only move slowly through the water as it is carried by waves.
The puffer fish also has funny teeth. These teeth stick out of the fish’s mouth and are used by the fish to open the shells of the creatures that live on the ocean floor.
This strange, ugly, and very poisonous fish is actually a very expensive kind of food in Japan. The Japanese call this fish “fugu”, and people have been known to pay $150 per person to eat a fugu meal (usually eight servings)!
Very brave people want to eat the most poisonous part of the fugu fish on purpose. They think that this part of the fish tastes the best! Strict laws have been passed to control restaurants which serve fugu; however, quite a few people have still died from eating fugu.Almost 200 people have died over the past 25 years.
When people eat fugu poison, they do not die on the spot. First, they feel a strange tickle on their lips and in their mouth. Then they can not feel anything with their fingers. Finally, they cannot move or speak. Death follows when they can no longer breathe. The poison may take only a few minutes or up to six hours to kill a person. There is no known cure for fugu poisoning.

Some places in the world have strange laws. It’s important for you to know about them before going there.
People who like to chew gum(口香糖) may have to leave Singapore. The government really wants to keep the city clean and will fine you for chewing gum.
Before you leave for the United Arab Emirates you’d better make sure you aren’t visiting during Ramadan(齋月). During that time you aren’t allowed to eat or drink in public. Tourists have been fined up to $275 for drinking in public.
Lovers spend so much time kissing each other goodbye at train stations that trains often start late. This law — no kissing your lover goodbye at train stations – is rather old, and is
n’t in use today in France.
In Thailand it’s against the law to drive a car or motorcycle without a shirt on, no matter how hot it is. Punishments are different in different areas and can include warnings and tickets costing about $10. No joke -- the local police will stop you.
Studies in Denmark have shown that cars with their headlights on are more noticeable by other drivers than those with their headlights off. Drivers there are required to leave their headlights on even during the day, or they may face a fine up to $100.
Do you often buy things using coins? Don’t do it in Canada. The Currency Law of 1985 doesn’t allow using only coins to buy things. Even the use of the dollar-coin is limited (受限制的). The shop owner has the right to choose whether to take your coins or not.
Make sure you know about these laws before your next trip. Better safe than sorry.

Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by caloric-expenditure（熱量消耗）charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜餅). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.
Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
If you have been sedentary (極少活動(dòng)的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.

2."Even exercise professionals accept half a point here" means "They ".

B. partially believe diet plays a supporting role in weight reduction
C. are not fully convinced that dieting can help maintain one's new weight
D. are not sufficiently informed of the positive role of exercise in losing weight
3.What was confirmed by the Boston University Medical Center's study?
A. Controlling one's calorie intake is more important than doing exercise.
B. Even occasional exercise can help reduce weight.
C. Weight reduction is impossible without exercise.
D. One could lose ten pounds in a year's time if there's no increase in food intake.
