阅读理解。     MIT researchers and their colleagues are working tofind out whether energy from trees
can power a network ofsensors(传感器)to prevent spreading forest fires.
     What they learn could also raise the possibility of usingtrees as silent guards along the
nation"s borders to discoverpotential threatssuchassmuggled (走私的 ) radioactivematerials.
     The U. S. Forest Service currently predicts and tracksfires with a variety of tools,
including remotc automatcdweather stations. But these stations arc expcnsive andsparsely
(稀疏地) distributed. Additionalsensors could savetrees by providing better local climate
data to be used in fireprediction models and earlier warnings. However,rechargingor
replacing batteries by hand at very hard-to-reach locationsmakes it impractical and costly.
     The new sensor system seeks to avoid this problem bydeveloping trees into a
self-sustaining power supply. Eachsensor is equipped with a battery that can be slowly
recharged using electricity produced by the tree. "A singletree doesn"t generate a lot of
power, but over time thetrickle (细流 ) chargeaddsup, justlike "-", saidShuguang Zhang,
one of the researchers on the project andthe associate director of the MIT" s Center for
Biomedica}Engineering( CBE). "
     The system produces enough electricity to allow the temperature and humidity sensors
to wirelessly send outsignals four times a day,or immediately if there"s a fire.Each signal
spreads from one sensor to another, until itreaches an existing weather station that sends
the data bysatellite to a forestry command center in Boise,Idaho. Scientists have long
known that trees can produceextremely small amounts of electricity. But no one knew
exactly how the energy was produced or how to takeadvantage of the power.1. What are the disadvantages of the remote automatedweather stations?
a. They cost too much.
b. They are of poor quality.
c. They are not enough.
d. They can"t reach remote places. A. a,b
B. b,d
C. a,c
D. b,c2. Which of the following is the best sentence to fill in theblank?

A. Far water does not put out near fire.
B. All rivers run into sea.
C. Many a little makes a miracle.
D. It never rains but it pours.

3. What would be the best title for the passage? A. Preventing forest fires with tree power
B. Trees can produce electricity
C. Tree power in daily life
D. Developing new energy

     There is no denying that students should learn something about how computers work, just
as we expect them at least to understand that the internal-combustion engine (内燃机) has
something to do with burning fuel, expanding gases and pistons (活塞) being driven. For
people should have some basic idea of how the things that they use do what they do. Further,
students might be helped by a course that considers the computer"s impact on society. But
that is not what is meant by computer literacy. For computer literacy is not a form of literacy
(读写能力); it is a trade skill that should not be taught as a liberal art.
      Learning how to use a computer and learning how to program one are two distinct
activities. A case might be made that the competent citizens of tomorrow should free
themselves from their fear of computers. But this is quite different from saying that all ought
to know how to program one. Leave that to people who have chosen programming as a
career. While programming can be lots of fun, and while our society needs some people
who are experts at it, the same is true of auto repair and violin-making.
Learning how to use a computer is not that difficu1t, and it gets easier all the time as
programs become more "user-friendly". Let us assume that in the future everyone is
going to have to know how to use a computer to be a competent citizen. What does the
phrase "learning to use a computer" mean? It sounds like "learning to drive a car", that is,
it sounds as if there is some set of definite skills that, once acquired, enable one to use a
computer.
     In fact, "learning to use a computer" is much more like "learning to play a game", but
learning the rules of one game may not he1p you play a second game, whose rules may
not be the same. There is no such a thing as teaching someone how to use a computer.
One can only teach people to use this or that program and generally that is easily accomplished.

1. To be the competent citizens of tomorrow, people should.A. try to lay a solid foundation in computer science
B. be aware of how the things that they use do what they do
C. learn to use a computer by acquiring a certain set of skills
D. understand that programming a computer is more essential than repairing a car.2. In the second paragraph "violin-making" is mentioned to show that .A. programming a computer is as interesting as making a violin
B. our society needs experts in different fields
C. violin-making requires as much skill as computer programming
D. people who can use a computer don"t necessarily have to know computer programming3. Learning to use a computer is getting easier all the time because .A. programs are becoming 1ess complicated
B. programs are designed to be convenient to users
C. programming is becoming easier and easier
D. programs are becoming readily available to computer users4. According to the author, the phrase "learning to use a computer" in Para. 3means learning.A. a set of rules
B. the fundamentals of computer science
C. specific programs
D. general principles of programming5. The author"s purpose in writing this passage is .A. to stress the impact of the computer on society
B. to explain the concept of computer literacy
C. to illustrate the requirements for being competent citizens of tomorrow
D. to emphasize that computer programming is an interesting and challenging job.

阅读理解     The secret of carrier pigeons" unbelievable ability to find their way home has been discovered by
scientists: the feathered navigators follow the roads just like we do.
     Scientists now believe the phrase "as the crow (乌鸦) flies" no longer means the shortest most
direct route between two points. They say it is likely that crows and other day birds also choose
AA-suggested routes, even though it makes their journeys longer.
     Scientists at Oxford University  spent 10 years studying homing pigeons using global positioning
satellite (GPS) and got a surprising result. The birds often don"t use the sun to decide their directions.
     Instead they fly along motorways, turn at crossing and even go around roundabouts (绕道) , adding
miles to their journeys.
     "It really has knocked our research team sideways to find that after a decade-long international
study, pigeons appear to ignore their inbuilt directional instincts (本能) and follow the road system,"
said Prof Tim Guilford, reader in animal behavior at Oxford University"s Department of Zoology.
    Guilford said pigeons use their own navigational system (导航系统) when doing long distance trips
or when a bird does a journey for the first time.
     "But once homing pigeons have flown a journey more than once, they can fly home on a habitual
route, much as we do when we are driving or walking home from work," said Guilford.
      "In short, it looks like it is mentally easier for a bird to fly down a road. They are just making their
journey as simpl e as possible." 1.What would be the best title of the passage? A. Birds Follow Roads as We do.
B. Why Pigeons Can Fly long Distance?
C. How Pigeons Find Their Ways Home?
D. Why Crows Fly the Shortest Distance? 2.What does the words "the feathered navigators" refer to? A. The pigeons.
B. The crows.
C. Day birds.
D. Animals that can fly. 3.Scientists used to think that homing pigeons often find their directions _______. A. by global positioning satellite
B. by the sun
C. by the road system
D. by following other birds 4.Why do homing pigeons tend to follow the road system during the journey? A. Because they don"t have their inbuilt directional instincts now.
B. Because their own navigational system doesn"t work.
C. Because it is too hard to use their own navigational system.
D. Because it is easier to make journey simple by following road system.

cream, or the pool-and have your child draw pictures of it or cut out pictures from magazines.Stick the
pictures onto paper to make a booklet and write text for it.When you"re done, read the book together.
Reread it whenever you like!
     Keep in touch.Kids don"t have to go away to write about summer vacation.Even if your family stays
home, they can send postcards to tell friends and relatives about their adventures.Ask a relative to be
your child"s pen pal and encourage them to write each week.
