  Many people catch a cold in the springtime and/or fall.It makes us wonder., if scientists can send a man to the moon, why can't they find a cure for the common cold.The answer is easy.There are literally hundreds of kinds of cold viruses out there.You never know which one you will get, so there isn't a cure for each one.

  When a virus attacks your body, your body works hard to get rid of it.Blood rushes to your nose and brings congestion with it.You feel terrible because you can't breathe well, but your body is actually "eating" the virus.Your temperature rises and you get a fever, but the heat of your body is killing the virus.You also have a runny nose to stop the virus from getting to your cells.You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold.

  Different people have different remedies for colds.In the United States and some other countries, for example, people might eat chicken soup to feel better.Some people take hot baths and drink warm liquids.Other people take medicines to stop the fever, congestion, and runny nose.

  There is one interesting thing to note--some scientists say taking medicines when you have a cold is actually bad for you.The virus stays in you longer because your body doesn't have a way to fight it and kill it.Bodies can do an amazing job on their own.There is a joke, however, on taking medicine when you have a cold.It goes like this:

  If takes about one week to get over a cold if you don't take medicine, but only seven days to get over a cold if you take medicine.

The reason that scientists cannot cure a common cold is __________.

A.we don’t know how we get cold
B.  we aren’t sure the exact kind of cold viruses
C.we don’t know when we will catch cold
D. we aren’t sure the exact scientific method

  Families separated by the Florida Straits were overjoyed Tuesday and Miami-based charter companies rushed to add seats and flights to their Havana routes after the Obama administration decided to let more Americans visit Cuba as often as they want, and spend as much as they like.

  The policy changes are sure to put more money into Cuba's dying economy, and many would-be travelers are already call for still more barriers to fall. Even Fidel Castro (菲德尔卡斯特罗) , who had belittled the changes Monday, yielded Tuesday that they were "positive, although minimal".

  The United States still doesn't let most Americans without ties to Cuba visit the island or send in money.But the change, announced Monday by the Obama administration, was among the most significant openings in the half-century of hostilities between the two countries.

  During the Bush administration, Americans with immediate family members on the island could visit once every three years and send up to $100 a month to their families.

  Now, there are no limits to travel or expense, and the definition of family is expanded to include relatives as distant as second cousins, as well as anyone else who lives as "family" in the home of the authorized traveler.

According to the article, what will this change in policy do for Cuba

A.It will boost the Cuban econom
B.It will help defeat Fidel Castr
C.It will make more Cubans come to the United State
D.It will decrease the number of Cubans coming to the United State

  People need to be active to be healthy.Our modem lifestyle and all the conveniences we've become used to have made us sitting much of the time - and that's dangerous for our health.Sitting around in front of the TV or the computer, riding in the car for even a short trip to the store and using elevators instead of stairs, all contribute to our inactivity.Physical inactivity is as dangerous to our health as smoking!

  Add up your activities during the day in periods of at least 10 minutes each.Start slowly ...and build up.If you're already doing some light activities move up to more moderate ones.A little is good, but more is better if you want to achieve health benefits.

  Scientists say add up 60 minutes of physical activity every day to stay healthy or improve your health.Time needed depends on effort - as you progress to moderate activities, you can cut down to thirty minutes, four days a week.

  Physical activity doesn't have to be very hard to improve your health.This goal can be reached by building physical activities into your daily routine.Just add up in periods of at least ten minutes each throughout the day.After three months of regular physical activity, you will notice a difference - people often say getting started is the hardest part.

  The winter in Iceland has been one of the worst ever.An animal that was born in Iceland and just returned there has enjoyed the weather.Keiko is a killer whale who is now living in a hidden bay.

  When Keiko was one or two years old, he was captured.This was in 1979.In 1982 he was moved to an amusement part in Ontario, Canada.Three years later another park took him to Mexico City.There, the 6.4-meter (21-foot) whale lived in a small pen with water that was too warm.In1993 the "Free Willy" movie made people aware of his state.In 1996 the Free Willy Keiko Foundation moved him to a pool in an aquarium in Newport, Oregon.

  The foundation has spent over $12 million to return Keiko to Iceland, his home.Late last year the 40,000-pound (18,100-kilogram) whale was flown on a C-17 transport plane to pen near the Wesman Islands.

  Critics thought Keiko would suffer in the cold water.Instead, he is enjoying the cold and becomes more active.He likes to jump out of the water to get sprayed by the salt spray.Since his return, he acts more like a wild whale.He dives more often, eats more live fish, and is more active.

  Keiko still isn't ready to go out alone into the open sea.Trainers hope to put him in a larger bay.They also hope to train him to follow a boat.They don't know what Keiko will do when he meets other sea animals.So far the only animals who have come near Keiko's cage left when they saw him.

  They would like to let Keiko free this summer.No one knows if he will be ready.If he isn't, the Keiko Foundation is ready to take care of him.It will cost about $1 million a year.

Critics thought that Keiko would __________.

A.die from the cold water in Iceland
B.be happy to return home
C.want to be free
D.be less active

单项选择题

根据以下资料,回答下面试题。

  The winter in Iceland has been one of the worst ever.An animal that was born in Iceland and just returned there has enjoyed the weather.Keiko is a killer whale who is now living in a hidden bay.

  When Keiko was one or two years old, he was captured.This was in 1979.In 1982 he was moved to an amusement part in Ontario, Canada.Three years later another park took him to Mexico City.There, the 6.4-meter (21-foot) whale lived in a small pen with water that was too warm.In1993 the "Free Willy" movie made people aware of his state.In 1996 the Free Willy Keiko Foundation moved him to a pool in an aquarium in Newport, Oregon.

  The foundation has spent over $12 million to return Keiko to Iceland, his home.Late last year the 40,000-pound (18,100-kilogram) whale was flown on a C-17 transport plane to pen near the Wesman Islands.

  Critics thought Keiko would suffer in the cold water.Instead, he is enjoying the cold and becomes more active.He likes to jump out of the water to get sprayed by the salt spray.Since his return, he acts more like a wild whale.He dives more often, eats more live fish, and is more active.

  Keiko still isn't ready to go out alone into the open sea.Trainers hope to put him in a larger bay.They also hope to train him to follow a boat.They don't know what Keiko will do when he meets other sea animals.So far the only animals who have come near Keiko's cage left when they saw him.

  They would like to let Keiko free this summer.No one knows if he will be ready.If he isn't, the Keiko Foundation is ready to take care of him.It will cost about $1 million a year.

If  Keiko can't adjust to the wild, the foundation __________.

A.will set him free anyway
B.will bring him back to the United States
C.will take care of him for the rest of his life
D.won’t be able to take care of him
