Researchers have developed new software using smart phones’GPS and imaging abilities that determine the exact location of distant objects as well as monitor the speed and direction of moving objects.The software could eventually allow smart phone-armed soldiers to target the location of their enemies.On the home front,the software could be used by everyone,including golfers judging distance to the green and biologists documenting the location of a rare animal without disturbing it.
“The great advantage of a Smartphone is that it provides so many tools in a single,readily available,relatively inexpensive package,”said Qia Wang,a doctoral student who led the development of the software.“For example,on the battlefield,a soldier needs a rangefinder,compass,GPS and other tools to get information before calling in an air strike.With our software,the soldier can have all those instruments in one device that can be purchased off the shelf.When that soldier returns from War,she can use the same Software to protect her family by clocking a speeder near her children’s school and catching the criminal on video.”
Wang and his colleagues developed their software to locate and track:
Targets of known size—when the size of the target is known.a single image is enough to pinpoint the target’s location.
Targets of unknown size—If the exact size of a target is unknown,the software uses two images to triangulate the location of the target·
Moving targets—By taking a short video of a moving target,the smartphone software can calculate how fast the target is moving and in what direction it is going.
“Currently,our software is limited by the physical abilities of smartphone hardware,but the devices are improving rapidly,”Wang said.“We expect that improvements in GPS accuracy,battery  life  and  camera  resolution  will  allow  our  software to  make  even  more  accurate observations.”
.From Paragraph 1 we can know that the new software can_______.

A.determine the speed of moving objects
B.1ocate objects in the distance exactly
C.defend soldiers against their enemies
D.help biologists protect rare animal

.The example given by Qia Wang is meant to ________________.

A.make an advertisement
B.describe the software briefly
C.show the benefits of the software
D.present the functions of smartphones

.How does the software calculate the speed of a moving object?

A.By taking a short video. B.By locating its position.
C.By taking a single image. D.By measuring real-life size.

.What’s Qia Wang’s attitude towards the future of the software?

A.Casual. B.Optimistic.
C.Cautious. D.Flexible

.What is the best title of the text?

A.Qia Wang,a Talented Doctoral Student
B.Use Smartphones to Their Full Potential
C.Targeting and Tracking With Smartphones
D.Smartphone-armed Soldiers on the Battlefield

Five years ago, I was sent to a better middle school. For me, everything there was new and strange. After I had been there for two months, there was an important test in the middle of the term. It covered all my courses. In that test, I didn’t get a good grade, but most of my classmates got an A or A’.
It made me upset for a long time. I felt everything in the world was changing. I thought my classmates were all better than me. During those days I was very unhappy.
One day, my aunt, after talking with my teachers, talked to me. She told me to think about what I had done in the past and what I should do in the future. I was shocked by her words. I thought about what I had done during the past months, and I found I had done nothing to improve my grades. I thought I should work harder.
After that, I paid more attention to the teachers’ talking in the classes, and I asked my teachers or my classmates when I didn’t understand something. I studied very late at night when I met with difficult problems. Most of all, I came to understand the importance of taking notes in class. As a result, I did better in some tests.
About three months later, the most important test came at the end of the term. This time, I stood out not only in my class but also in the grade. From then on, I have tried to do my best when I do something because I know if I want something, I should work hard for it.

One of the most difficult things for children to deal with when moving to a new town is leaving their friends and making new ones.
We once moved and one of our new neighbors told us about a summer camp at the Recreation Center all the kids went to. My husband and I looked into it and we found it was unbelievably cheap. I had the kids sign up (报名) the next day so that they could know more kids there.
Another thing we did was to have them sign up for sports when school started. They were happy to be on teams with new friends they made. This also gave me a chance to meet new people and from them I sometimes got some useful ideas for my new books.
If you’re just moving to a new house in the same city you live in now, it won’t really be a problem unless your kids are changing schools. If they are, it is a great idea to have them take the address book to school. Thus, your children won’t feel “lost” without their old friends.
If you’re able to, over the summer vacation, try inviting the friend your child misses most to come and visit your new home for a week, or even a few weeks. I know this can be difficult if that child has to fly, but maybe you can work out a plan with the child’s parents. Think how happy the kids will be when they meet!
The author had her kids sign up for the summer camp mainly because _____.

A.she could afford the cost B.she was asked to do so by her kids
C.it could give her kids a chance to meet more kids
D.it could make the summer holiday not so boring

A.a summer camp at the Recreation Center was very cheap
B.having the kids take part in sports is good for both the author and her kids
C.parents should ask their children not to think of their old friends
D.parents should create more chances for children to make new friends

C.get along with their new neighbors
D.help their children get used to the new school life

When people in the U.S. have company or when they're invited to (formal or informal)get-together, they usually make a point of trying to make others feel comfortable and relaxed.On the whole, they tend to be informal. Men shake hands, but usually only when they're introduced. Male friends and business associate who haven't seen each other in a while may shake hands when they say hello. Women usually don't shake hands when being introduced to each other. When a woman and man are introduced, shaking hands is up to the woman. Americans rarely shake hands to say goodbye, except on business occasions. American women are used to being independent. They are used to going to places by themselves, making their own money, and often living alone. Sometimes they will ask men for help, but they usually don't want to be protected. Since the women's movement started, it's not always clear whether women expect men to open doors or help them into their coats. American women may start conversations with men or even ask them to dance.
There are a lot of Americans who don't smoke or drink, and many who don't want people to do those things in their houses. It's always best to ask for permission before you,bring alcohol to a dinner or before you light up a cigarette, if you are with people you don't ,know very well. Non-smokers have become more militant (好战的) about smoking in public places. Many restaurants, for example, have set up special areas for smokers.
House guests may bring gifts when they come to visit, and they often offer to help in some way. As a guest, you may want to ask your host or hostess if there's anything you can do to help in the kitchen. In many cases, the gesture is more important than actually helping.
"…the gesture is more important than actually helping." Here "gesture" means_________.

A.态度 B.话题 C.姿态 D.言行

In the United States, 30 percent of the people have a “weight problem”。To many people the cause is obvious (明显的): they eat too much. But scientific evidence (证据) does little to support this idea. Going back to America of 1910, we find that people were thinner than today, yet they ate more food. In those days people worked harder physically, walked more, used machines much less, and didn’t watch television.
Several modern studies, moreover, have shown that fatter people don’t eat more on average than thinner people. A 1979 study of 3,545 London office workers showed that fat people eat less than slim (苗条的) people.
Studies also show that slim people are more active than fat people. A study by a research group at Stanford University found the following interesting facts:
The more the man ran, the greater loss of the body fat
The more they ran, the greater increase in food intake.
Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
Nowadays many Americans have the problem that ______.

A.they are too slim B.they work too hard C.they are too fat D.they lose too much body fat

According to the passage, how many people in 900 Americans have a “weight problem”?
