7.A long-term American study shows the importance of early education for poor children.The study is known as the Abecedarian Project.It involved more than one-hundred young children from poor families in North Carolina.
Half of the children attended an all-day program at a high-quality child-care center.The center offered educational,health and social programs.Children took part in games and activities to increase their thinking and language skills and social and emotional development.The program also included health foods for the children.
The children attended the program from when they were a few weeks old until the age of five years.The other group of children did not attend the child-care center.After the age of five,both groups attended public school.
Researchers compared the two groups of children.When they were babies,both groups had similar results in tests for mental and physical skills.However,from the age of eighteen months,the children in the educational child-care program did much better in tests.
The researchers tested the children again when they were twelve and fifteen years old.The tests found that the children who had been in the child-care center continued to have higher average test results.These children did much better on tests of reading and mathematics.
A few years ago,organizers of the Abecedarian Project tested the students again.At the time,each student was twenty-one years old.They were tested for thinking and educational ability,employment,parenting and social skills.The researchers found that the young adults who had the early education still did better in reading and mathematics tests.They were more than two times as likely to be attending college or to have completed college.In addition,the children who received early education were older on average,when their first child was born.
The study offers more evidence that learning during the first months and years of life is important for all later development.
The researchers of the Abecedarian Project believe their study shows a need for lawmakers to spend money on public early education.They believe these kinds of programs could reduce the number of children who do not complete school and are unemployed.

77.The Abecedarian Project has lastedC.
A.almost one year
B.about five years
C.more than 20 years
D.no more than 15 years

A.have their children at later ages
B.get more help from other people
C.have no parenting or social skills
D.are poorer at reading and mathematics
79.What don't we know about the Abecedarian Project after reading the text?D
A.What the children learned at the child-care center.
B.How important early education is for poor children.
C.How many children are involved in the Abecedarian Project.
D.Whether lawmakers will spend money on public early education.
80.The study of the Abecedarian Project shows that early educationC.
A.costs a lot of money
B.leads to a lower birthrate
C.can improve the life of poor children
D.is not important for later development.

3.Move Earth-It's Not Science FictionLONDON-Scientists have found an unusual way to prevent our planet from overheating:move it to a cooler spot.All you have to do is send a few comets(彗星)in the direction of Earth,and its orbit will be changed.Our world will then be sent spinning into a safer,colder part of the solar system.
This idea for improving our climate comes from a group of US National Aeronautics and Space Administration (NASA) engineers and American astronomers.They say their plan could add another six billion years to the useful lifetime of our planet-effectively doubling its working life.
The plan put forward by Dr.Laughlin,and his colleagues Don Kory can sky and Fred Adams,needs carefully directing a comet or asteroid (小行星)so that it passes close by our planet and sends some of its gravitational energy to Earth.
"Earth's orbital speed w ould increase as a result and we would move to a higher orbit away from the Sun,"Laughlin said.
Engineers would then direct their comet so that it passed close to Jupiter or Saturn.The comet would pick up energy from one of these giant planets.Later its orbit would bring it back to Earth,and the process would be repeated.
In the short term,the plan provides an ideal way to global warming,although the team was actually concerned with a much greater danger.The Sun is certain to heat up in about a billion years and so"seriously compromise"our biosphere(生物圈)-by cooking us.
That's why the group decided to try to save Earth.
The plan has one or two worrying aspects,however.For a start,space engineers would have to be very careful about how they directed their asteroid or comet towards Earth.The smallest miscalculation(误算)in orbit could fire it straight at Earth-with deadly results.
There is also the question of the Moon.As the current issue of Scientific American magazine points out,if Earth was pushed out of its current position,it is"most likely the Moon would be stripped away from Earth".This would greatly change our planet's climate.

67.What makes the scientists plan to move Earth?C
A.A few comets are moving to the direction of Earth.
B.Earth's working life is coming to an end soon.
C.Earth will become too hot for mankind to keep alive.
D.The moon is moving farther and farther away from Earth.
68.If the plan is successful,Earth will have a working life ofAyears.
A.12 billion B.6 billion C.18 billion D.24 billion
69.What serious problems might the plan cause according to the passage?A
A.The comet might hit Earth and man might lose the Moon.
B.Earth might be moved too far away and man might be frozen to death.
C.The comet might hit Jupiter or Saturn and never return to Earth.
D.Earth's working life might be greatly shortened.
70.What does the underlined word"compromise"mean?D
A.Surround.B.Benefit.C.Share.D.Endanger.

15.No one can deny that buttons are an important device.Whenever we see a button,we are eager to press it because we know something will happen.This is true in most cases,for example on a doorbell and on the"on/off"button on the TV.But some buttons are actually fake,like the"close"button on a lift.
Many people are in the habit of pressing the"close"button because they don't have the patience to wait for the lift doors to shut.But lifts'"close"buttons are a complete scam (骗局),at least in the US-the doors will not close any faster no matter how hard you press.
It started in the 1990s when the Americans with Disabilities Act was passed in the US,making sure that all lifts stayed open long enough so that people with disabilities could enter.Only US firefighters and repairmen can use the buttons to speed up the door-closing process if they have a code or special keys.
But to normal lift riders,the buttons aren't completely useless.According to psychologists,fake buttons can actually make you feel better by offering you a sense of control.
"Perceived (能够感知的) control is very important.It reduces stress and increases well-being,"Ellen J.Langer,a psychology professor,said,"having a lack of control is associated with depression."
Experts have revealed that a lot of buttons that don't do anything exist in our lives for this same purpose.For example,many offices in the US have fake thermostats (温度调节器) because people tend to feel better when they think they can control the temperature in their workspace.
But psychologists found it interesting that even when people are aware of these little"white lies",they still continue to push fake buttons because as long as the doors eventually close,it is considered to be worth the effort.
"That habit is here to stay,"John Kounios,a psychology professor,said."Even though I have real doubts about the traffic light buttons,I always press them.After all,I've got nothing else to do while waiting.So why not press the button in the hope that this one will work?"

25.What was the author's main purpose in writing the article?D
A.To explore people's different habits when it comes to pushing buttons.
B.To describe some different kinds of fake buttons.
C.To explain the advantages and disadvantages of fake buttons.
D.To analyze the functions of fake buttons.
26.In America,the"close"buttons on liftsA.
A.are fake for the convenience of disabled people
B.work only when people press them hard for a while
C.were specially designed to give people a sense of control
D.cannot speed up the process of closing the door in any case
27.The underlined part"for this same purpose"in Paragraph 6 refers toB.
A.making people more patient              
B.giving people perceived control
C.helping people to build up confidence      
D.making people with depression feel better
28.According to John Kounios,people who press fake buttonsC.
A.should give up this habit
B.consider what they do to be meaningless
C.probably do so to kill time
D.don't know that what they press is fake.

2.Maybe you are an ordinary student.(36)BThis is not necessarily so.Anyone can become a better student if he or she wants to.Here's how:
Plan your time carefully.When planning your work,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 arrange your time for eating,sleeping,dressing,etc,then decide a good,regular time for studying.(37)CA weekly schedule may not solve all your problems,but it will force you realize what is happening to your time.
Make good use of your time in class.(38)FListening carefully in class means less work later.Taking notes will help you remember what the teacher says.
Study regularly.When you get home from school,go over your notes,review the important points that your teacher is going to discuss the next day,read that material.(39)AIf you do these things regularly,the material will become more meaningful,and you will remember it longer.
Develop a good attitude towards tests.The purpose of a test is to show what you have learned about a subject.The world won't end if you don't pass a test,so don't be over-worried.
(40)EYou will probably discover many others after you have tried these.

A.This will help you understand the next class.
B.You probably think you will never be a top student.
C.Don't forget to set aside enough time for entertainment.
D.No one can become a top student unless he or she works hard.
E.There are other methods that might help you with your study.
F.Take advantage of class time to listen to everything the teacher says.
G.Make full use of spare time to take note of what the teacher says in class.
