but a faster network loads Web pages more quickly, true GPS functionality allows it to easily
find places nearby, and the new $199 price (down from $400) makes it an affordable luxury.
Before deciding whether to buy, however, make sure you can actually take advantage of
the iPhone 3G"s high-speed data network. 3G stands for third-generation, which in non-geek
speak translates to Web pages and mail messages that, ideally, load about three times faster
than on the original iPhone. Even better, 3G coverage enables you to make a phone call and surf
the Web at the same time. That"s great, if you live or work in a place where the 3G network of
AT&T (美国电话电报公司) (the sole wireless carrier of the iPhone) is active. That"s not so
great in cities like New York where AT&T"s cellular coverage is awful. As one of my colleagues
in New York City, who bought the original iPhone, commented, "It"s just a toy. You can"t make
phone calls on it, so I carry my Verizon phone with me all the time."
The real fun begins when you tap on the icon called "App Store" and start browsing the hundreds
of add-on applications that have been developed just for the iPhone. You"ll find tons of games (I like
JirboBreak, a free game inspired by the Atari classic Breakout) and mobile versions of popular
websites like Pandora, Facebook, MySpace and the New York Times. Most apps will cost you,
but the vast majority are $9.99 or less. The apps work on the old iPhones too, but you"ll enjoy them
a lot more on the iPhone 3G because many of the programs, including Yelp (local business reviews),
Whrrl (mobile social networking) and UrbanSpoon (restaurant reviews), use your exact location-
provided by the iPhone 3G"s GPS chip-to make recommendations. The apps also load much faster
over the 3G network.
B. It has a faster network
C. It is easy to locate a place
D. It is too expensive for people to buy
B. ecause he prefers Verizon phone better.
C. Because AT&T"s cellular coverage is terrible there.
D. Because Verizon phone enables him make a phone call and surf the Web at the same time.
B. many apps have been developed for the iPhone.
C. Most apps are very expensive.
D. Pandora, Facebook, MySpace and the New York Times are popular websites.
B. appreciative
C. optimistic
D. pessimistic
New rules and behavior standards for middle school students came out in March. Middle school is going
to use a new way to decide who the top students are. The best students won"t only have high marks. They
will also be kids who don"t dye (color) their hair, smoke or drink. The following are some of the new rules.
Tell the truth. Have you ever copied someone else"s work on an exam? Don"t do it again! That"s not
something an honest student should do. If you have played computer games for two hours in your room,
don"t tell your parents you have done homework.
Do more at school. Good students love animals and care for other people. April is Bird-Loving Month in
China. Is your school doing anything to celebrate? You should join! That way, you can learn more about
animals and how to protect them. When more people work together, it makes more fun for everyone.
Have you ever quarreled with your teammates when your basketball team lost? Only working together
can make your team stronger. Be friendly to the people you are with. Try to think of others not only yourself.
Be open to new ideas. Have you ever thought that people could live on the moon? Maybe you"ll discover
Earth II someday. Don"t look down on new ideas. Everyone"s ideas are important. You should welcome them,
because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates? Don"t let it happen to you.
If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for your studies. But some things on the Internet
aren"t for kids, so try to look at Web pages that are good for you. You can use the Web for fun or homework.
Can"t you find any good Web sites for children? Here are some: http://kids.eastday.com;http://chinakids.com;
http://www.cycnet.com
B. what they should do at school
C. what is right and what is wrong
D. how they can protect themselves
B. working together with others
C. being a good friend to others
D. getting on well with others
B. do more at school
C. care for others
D. use the Internet
Sometimes it is helpful if you know what common proverbs mean. Here are a few examples.
1) "Once bitten, twice shy." If a dog bites me, I shall be twice as careful in future when I see it. This
proverb is also used to apply to many things and not only to dogs. If you have been cheated at a shop, you
will not go the same shop again.
2) "A bird in the hand is worth two in the bush." If I am a hunter, trying to catch birds, it is better to
catch one than to see two birds in a bush but not able to catch them. Thus this means that what you have
already got is better than the chance of being able to get something bigger in future.
3) "Too many cooks spoil the broth (soup)". When too many people do something, they get in each other"s
way and do a bad job.
4) "To pour oil on troubled waters" is to try to calm things down. Oil is lighter than water. If a ship is in
trouble at sea, another ship may come to help it. The second ship can send small boats to rescue people.
However, it may first pour oil on the sea to make the sea less rough.
5) "Don"t be a dog in a manger( 槽 )" means " Don"t be selfish." In a stable ( 马房 ), the manger is the
place where the horse"s food is put. Sometimes a dog will sleep in the manger and bark when a horse comes
to get its food. The dog does want to eat the lay in the manger but it will not let the horse eat it.
6) "He is sitting on the fence" means that somebody will not say whether he is in favor of a plan or against
it. He is sitting on a fence between two opposing sides, perhaps waiting to see which side will win.
7) "He who pays the piper calls the tune." A piper is a musician. The man who employs or pays a musician
can say what tunes the man will play. Thus this means that if a man provides the money for a plan, he can say
how it will be carried out.
8) "You can"t get blood out of a stone" means that you cannot get something from a person who has not
got any of the things you want. e. g. you cannot get a million dollars from a poor man.

the passage.
Write NO MORE THAN THREE WORDS for each answer.
1. Plan your time carefully. When you plan your week, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don"t forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.
2. Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television! When you sit down to study, concentrate on the subject.
3. Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what the teacher says.
4. Study regularly. When you get home from school, go over your notes. Review the important points that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read that material will become more meaningful, and you will remember it longer.
5. Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won"t end if you don"t pass a test, so don"t be overly worried. There are other methods that might help you with your studying. You will probably discover many others after you have tried these.
At 2:30 December 5, 1945, five US Navy training planes took off in clear weather from the base Lauderdale, Florida. The planes flew east over the coast… and disappeared. The group was Flight 19, on a run between
Florida and Bahamas. Tailor was the group leader. At about 3:40, Tailor reported that his compasses (指南针)
were not reading properly. The other planes followed their leaders aimlessly, first east, then west, then
northeast over the ocean, as Tailor tried to make sure of the direction by radio. Then, suddenly Tailor was
heard to give orders to dive…
Quickly, two giant Martin seaplanes were sent up to search for Flight 19. Several hours later, the wind
became strong and visibility (能见度) dropped. A return to base was ordered. But only one of the Martin
seaplanes landed. Four days later, the Navy and Coast Guard combed a 100,000 square-mile area with more
than 100 planes and ships. No sign was ever shown of the missing planes.
Today, people have noted the disappearance of many ships and planes in the southwest part of the North
Atlantic and began to call this area the Bermuda Triangle.
The points of the triangle are Bermuda, Puerto Rico and a particular place in the Gulf of Mexico, west of
Florida. It is a two-faced water world of tiny islands, bright beaches and beautiful waters. Yet thick fogs,
powerful currents (激流) and sudden storms are hidden behind this smiling surface.
B. In the northeast part of the Atlantic Ocean.
C. To the southwest of Bermuda in the Atlantic Ocean.
D. To the northeast of Bermuda in the Atlantic Ocean.
B. Six
C. Two
D. Only one.
B. fly over
C. do up one"s hair with a comb
D. search all over
(F = Florida, Bm = Bermuda, PR = Puerto Rico, Bh = Barhamas, MG =the Gulf of Mexico,
Atl = the Atlantic Ocean, B=Base)
Houston, a professor of the University of Massachusetts Medical School, led a group of scientists that
investigated how pre-recorded videos of hypertension (高血压) patients" talking about their medical histories
helped another group of patients with high blood pressure to control their condition over several months.
Houston was surprised by their studies that suggested that communication can be a powerful tool in
medicine. They showed that those who had had similar experiences, when talking to someone with a similar
background, could help change their behavior to become healthier. Hypertension is difficult to control, since
it is dependent on diet, exercise and mental state. Medical treatments with drugs, and lifestyle therapies(疗法)
have been relatively ineffective because people find it hard to follow those medical requirements.
In the test, his team carefully chose their story-tellers from 230 members of a patients" community with
whom they could most easily relate. Next, they divided their study population into two groups. One received
three interactive (互动) DVDs containing the tellers" stories of their experiences in living with and treating their
hypertension. The other were given educational discs on an unrelated health topic. The study volunteers
reported that they had listened to the DVDs, and after three months, those who heard the stories of the
hypertensive patients lowered their blood pressure.
While the study did not address how the story-telling influenced the patients" behavior, Houston suspects
that watching patients of similar backgrounds who had a similar medical experience helped to motivate them
to seek medical help to their hypertension. They found that after six months the difference in blood pressure
between those who watched the story-tellers and those who observed the unrelated videos remained,
suggesting that the story-telling continued to have an effect.
B. introduce some medical treatments of hypertension
C. introduce a good lifestyle for hypertensive patients
D. tell scientific discoveries of the scientist group
B. communication has some medical effects
C. medical treatments have no effect at all
D. people don"t follow the medical requirements
B. Both the groups used the same videos about health topic.
C. The two groups lowered blood pressure in different degrees.
D. The story-tellers were hypertension patients as well.
B. Medical treatments of blood pressure.
C. Storytelling may help lower blood pressure.
D. Suggestions about how to lower blood pressure.
