14.Cell Phones:Hang Up or Keep Talking
Millions of people are using cell phones today.In many places,it is actually considered unusual not to use one.(36)BThey find that the phones are more than a means of communication-having mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professionals worried.Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones.Mobile phone companies are worried about the negative publicity(负面报道)of such ideas.(37)E
On the other hand,signs of change in the issues of the brain and head can be detected with modern scanning equipment.In one case,a traveling salesman had to retire at a young age because of serious memory loss.(38)FThis man used to talk on his mobile phone for about six hours a day,every day of his working week,for a couple of years.
(39)DThe answer is radiation(辐射).High-tech machines can detect very small amounts of radiation from mobile phones.Mobile phone companies agree that there is some radiation,but they say the amount is too small to worry about.
As the discussion about the safety continues,it appears that it's best to use mobile phones less often.
(40)GUse your mobile phone only when you really need it.In the future,mobile phones may have a warning label that says they are bad for your health.So for now,it's wise not to use your mobile phone too often.

A.They will possibly affect their benefits.
B.In many countries,cell phones are very popular with young people.
C.What do the doctors worry about?
D.What is it that makes mobile phones potentially harmful?
E.They say that there is no proof that mobile phones are bad for your health.
F.He couldn't remember even simple tasks.
G.Use your regular phone if you want to talk for a long time.

5.I want to be a writer,an inventor,a social worker,and mayor of New York City.My future is no great mystery (谜) to me,and yours doesn't have to be a mystery either!All it takes is a goal,a little planning,and a lot of self-confidence.
I get excited when I think about what I can do,and so should you.Every dream can become a reality if you work at it.You don't have to limit yourself to doing just one thing.I want to do lots of things,like Benjamin Franklin.He was a writer,an inventor,a politician,and a scientist.

Be realistic when you make your goals but allow a little room for dreaming.Remember,it's OK you're your future to be a little mysterious.That's what makes it so exciting.Someday you may be an astronaut,a carpenter,an ambassador,a writer,a ballet dancer,or whatever else interests you.You may even do it all!

4.The movies just wouldn't be the same without the warm buttery taste of popcorn.Amazingly,this delicious treat started its life as a corn kernel(玉米粒)-and not from just any corn.Popcorn is a type of sweet corn that was originally grown in Mexico and spread to China,India and elsewhere.It is the only kind of corn that will pop.Today,most of the world's popcorn is grown in the United States.
Every popcorn kernel contains a tiny drop of water,surrounded by soft starch(淀粉).When the popcorn is heated,the water turns into steam.This puts pressure on the surrounding hard kernel,forcing it to explode.The soft starch increases about 40times in size as the corn kernel turns itself inside out.
In the 1500s popcorn was an important food source for the Aztec Indians of central and southern Mexico.But it wasn't only food.It was also used in ceremonies or in headdresses and necklaces.By the time the Europeans arrived in America,popcorn had spread through most of the American Indians.
Some early American settlers ate popcorn with cream and sugar for breakfast.But it wasn't until the late 1800s that popcorn became popular.The demand for popcorn increased and farmers began farming popcorn.The first mobile popping machine was invented in 1885,and popcorn was sold by street sellers much like hot dogs are sold today.
During the Great Depression of the 1930s,the popcorn business still thrived as people could still afford it.Then in the 1950s television arrived and popcorn consumption decreased.People stayed home and stopped going to the theatre.But the link between movies and popcorn had already existed.Soon people began making popcorn at home on the stove.Later,microwave popcorn was introduced.
Today the movies have regained popularity and popcorn has once again become the favorite.
1.Popcorn was first planted inD.
A.China  
B.America
C.India  
D.Mexico
2.Why does the corn kernel pop when heated?B
A.Because it is covered with soft starch.
B.Because the pressure inside is too big.
C.Because the starch becomes bigger in size.
D.Because there is water inside the kernel.
3.We can know from the passage thatA.
A.popcorn began to be farmed in the late 1800s
B.popcorn was only a kind of food in the 1500s
C.hot dogs used to be sold by street sellers
D.people stopped going to the movies without popcorn
4.The underlined word"thrived"in the fifth paragraph probably means"D".
A.started to be popular
B.was seriously affected
C.suffered a lot
D.developed very well.
