Next fall when you see geese heading south for the winter or flying in “ V” formation (队形), you might consider what science has discovered as to why they fly that way.
As each bird spreads its wings，it creates an uplift (上升力) for bird immediately following. By flying in “ V” formation the whole flock (鸟群) adds at least 71% greater flying range, than if each bird flies on its own. People who share a common direction arid sense of community can get where they are going more quickly and easily because they are traveling on the thrust (推动力) of one another.
When a goose falls out of the formation, it suddenly feels the drag and resistance of trying to go it alone and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we have as much sense as a goose, we will stay in formation with those who are headed the same way we are. When the head goose gets tired, it flies backwards and another goose flies point. It is sensible to take turns doing demanding jobs, whether it is with people or with geese flying south.
Geese honk (雁叫) from behind to encourage those up front to keep up their speed. What do we say when we honk from behind?
Finally and this is important, when a goose gets sick or is wounded by gunshots, and falls out of formation, two other geese fall out with that goose and follow it down to lend help and protection. They stay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on their own, or with another formation to catch up with their group. If we have the sense of a goose, we will stand by each other like that.
1.The first three paragraphs chiefly deal with .
A. scientific discovery about geese.
B. the importance of flight formation.
C. the advantages of “V” formation.
D. the reasons for geese’s flight.
2.The phrase which can best replace “stand by” in the last sentence is “ ”.
A. be against. B. support.
C. sit by. D. obey.
3.What does the author want us to learn from the geese?
A. Teamwork. B. Sympathy.
C. Kindness. D. Intelligence.

A new smart phone system under development can locate you even when you’re inside a building, which GPS can't do. While the concept sounds powerful, it’s not yet clear how practical it might be.
The set-up, called SurroundSense, sends information from cameras and microphones—gear in the latest smart phones—to a server that produces a fingerprint of the location.
“You can’t tell much from any of the measurements individually, but when combined, the optical (光学的), acoustic (声学的) and motion information creates a unique fingerprint of the space,” said Ionut Constandache, a student in computer science.
The system distinguishes between two indoor spaces in this manner: It knows that a bar is likely to be dark and noisy and people move little, sit a lot, whereas a department store will be brightly lit, contain vibrant colors, and will see a lot of people moving up and down passages. The more the system is used, the more it learns about specific places.
More work is needed before the set-up would be ready for prime time, however. For now, it can’t work if a person’s cellphone is in a handbag or otherwise unable to employ the camera. Finally it would be best served if paired with phones that were worn on the wrist or hung around the neck. Batteries, too, are a problem.
Students on the research team went out across Durham, North Carolina, with their cellphones collecting data in different types of businesses. The students mirrored the actions of the selected customers so that they would not prejudice the measurements.
“We went to 51 different stores and found that SurroundSense achieved an average accuracy (精确性) of about 87 percent," Constandache said.
“As the system collects and analyzes more and more information about a particular site, the fingerprint becomes more precise,” said Romit Roy Choudhury, professor of computer engineering. “Not only is the ambience different at different locations, but also can be different at different time at the same location.”
1.We can infer from the first paragraph that GPS .
A. can find you wherever you are
B. can make too much loud noise
C. can only find outside things
D. isn’t really practical yet
2.Why did students mirror the actions of the selected customers?
A. To get a reasonable result.
B. To collect data in different ways.
C. To receive information about a particular site.
D. To learn more about specific places.
3.The underlined word “ambience” in the last paragraph may mean .
A. the fingerprint of the location
B. the character of a place
C. the existence of people
D. the area of store
4.The main idea of the passage is about .
A. comparing GPS with a smart cellphone
B. the development of cellphones
C. a cellphone knowing where you are
D. what kind of future cellphones face

March 16th is World Sleep Day. This year’s slogan (标语) is “Breathe Easily, Sleep Well”. Its aim is to celebrate the benefits of good and healthy sleep.
Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.
But many students don’t get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others, they may even have insomnia which might keep them awake (醒着的)all night.
These sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, the lack of sleep may make them depressed (沮丧的).
Luckily, with good sleeping habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.
1.If Li Hong is 15years old, how much sleep does she need every night?
A. 10-12 hours. B. 8-9 hours.
C. 7 hours. D. Less than 7 hours.
2.What might happen if teenagers don’t get enough sleep?
A. They might do well in sports.
B. Their bodies and brains might grow better.
C. They might feel depressed.
D. They might not be able to finish their schoolwork.
3.The underlined word “insomnia” means “_______” in Chinese.
A. 健忘症 B. 肥胖症
C. 多动症 D. 失眠症
4.Which of the following are good sleeping habits?
a. Sleeping in a bright place.
b. Going to bed at the same time.
c. Sleeping in a dark and quiet place.
d. Drinking something that makes you excited.
A. a-b B. a-c
C. b-c D. b-d
