The 100-kilogram blue solar car invented by 10 students at Southwest University"s College of Engineering
and Technology in Chongqing has a top with four solar panels that charge the battery that powers the auto.
Its speed is between 30-40 kilometers per hour and when fully powered the car can be driven as far as 50
kilometers. "The car is easy to drive. A person without any driving experiences could learn to use it in several
minutes. It fits for campus and the golf course," said He Daijie, the leader of the invention team and a senior
at the college. Or if one prefers it can be turned into moped scooter (电动助力车), he said.
Four students at Shenyang University of Technology in Liaoning Province invented a door light powered
by electrical energy produced by opening and closing a door. When people open or close a door, the door
produces mechanical energy that could be turned into electrical energy. After numerous tests for several
months, the students fixed a joint lever above the door that connects the door and a speeding gear case to drive
a generator attached to the door and send energy to storage cells. The storage cells provide electrical energy
for the light.
A college student"s dorm door is opened and closed about 60-100 times a day, which could produce 160-
280 milliamps of electrical energy. It takes 160 milliamps to keep a light working for at least 10 hours, said
Xia Yingbiao, one of the invention team members and a mechanical designer and manufacturing and automation
junior. If these lights were used with the invention at the entrances in Shenyang schools, about 700,000
kilowatt hours a year would be saved, the team said. The university is applying patents for the invention.

make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important
to give your child the space he needs to grow while gently letting him know that you you"ll still be there for
him when he needs you.
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use
or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something,
don"t insist he tell you what"s on his mind. The more you insist, the more likely that he"ll clam up. Instead, let
him attempt to solve (解决) things by himself. At the same time, remind him that you"re always there for him
should he seek advice or help. Show respect for your teenager"s privacy (隐私). Never read him his mail or
listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family"s
telephone for too long, tell him he can talk for15 minutes, but then he must stay off the phone for at least an
equal period of time. This not only frees up the line so that other family members can make and receive calls,
but teaches your teenager moderation (节制). Or if you are open to the idea, allow your teenager his own
phone that he pays for with his own pocket money or a part-time job

global economic crisis awakening a public thirst for knowledge about how the financial system works.
Applications for degree courses beginning this autumn were up by 15% this January, according to
UCAS, the Universities and Colleges Admissions Service. A spokesman for the Royal Economic Society
said applications to do economics at A-level were also up.
Professor John Beath, the president of the society and a leading lecture at St Andrews University,
said his first-year lectures-which are open to students from all departments-were drawing crowds of 400,
rather than the usual 250.
"There are a large number of students who are not economics majors, who would like to learn something
about it. One of the things I have done this year is to relate my teaching to contemporary events in a way
that one hasn"t traditionally done." He added.
University applications rose 7% last year. But there were rises above average in several subjects. Nursing
saw a 15% jump, with people"s renewed interest in caters in the public sector (部门), which are seen as
more secure in economic crisis.
A recent study showed almost two thirds of parents believed schools should do more to teach pupils
about financial matters, and almost half said their children had asked them what was going on, although a
minority of parents felt they did not understand it themselves well enough to explain.
Zack Hocking, the head of Child Trust Funds, said:"It"s possible that one good thing to arise from the
downturn will be a generation that"s financially wiser and better equipped to manage their money through
times of economic uncertainty."
B. connected with the present situation
C. open to both students and their parents
D. warmly received by economics
B. higher pay
C. fewer applications
D. better reputation
B. more students should be admitted to universities
C. the teaching of financial matters should be strengthened
D. children should solve financial problems themselves
B. have access to better equipment
C. confide about their future careers
D. get jobs in Child Trust Funds
B. Economics is attracting an increasing numbers of students.
C. college students benefit a lot from economic uncertainty.
D. parents are concerned with children"s subject selection.
adults. That"s unfortunate, because saying hello is more than just saying hello-it is recognition of another"s
worth. How might the world change-how might we change-if we mastered this word? To find out, I spent
one month saying hello to every person I met. Here"s what I"ve learned.
[2] It can boost (促进) productivity. In one of the few studies ever done on this subject, Allan, an
assistant professor of special education at Oklahoma State University, had middle school teachers greet their
students individually each morning. This exchange of greetings raised the kids" productivity. School went
from impersonal to personal, and that resulted in more class participation and better grades.
[3] Environments influence friendliness. One study found that people in the city were kiss likely to one
hands with a stranger than those in the countryside. And researchers say, pleasure environments generally
encourage more smiles and hellos than unpleasant ones. My experience was similarly. Whatever the reason,
my urban hellos were answered far less often than my rural one. Similarly, people in vacation spots, like the
Jersey Shore, were far friendlier than those hurrying work downtown.
[4] It"s a form of universal health insurance. It"s impossible to say hello without smiling. And smiling has
been shown to lower blood pressure, relieve stress and boost happiness. Apparently, a smile creates a similar
effect in the recipient (接受者).
[5] So maybe we can make the world a better place by _____. After a month of doing it. I feel lighter
and more connected and I have a better sense of well-being.

solution to laptop computer theft: a program that lets owners give their property a voice when it has been
taken.
The program allows users to display alerts on the missing computer"s screen and even to set a spoken
message. Tracking software for stolen laptops has been on the market for some time, but this is thought
to be the first that allows owners to give the thief a piece of their mind.
Owners must report their laptop missing by visiting a website, which sends a message to the model:
a red and yellow "lost or stolen" sign appears on its screen when it is started. Under the latest version (版
本) of the software, users can also send a spoken message.
The message can be set to reappear every 30 seconds, no matter how many times the thief closes it.
"One customer sent a message saying, "You are being tracked. I am right at your door"," said Carrie
Hafeman, chief executive of the company which produces the program, Retriever.
In the latest version, people can add a spoken message. For example, the laptop"s speakers will say:"Help,
this laptop is reported lost or stolen. If you are not my owner, report me now."
The Retriever software package, which costs $29.95 but has a free trial period, has the functions of
many security software programs.Owners can remotely switch to an alternative password if they fear that
the thief has also got hold of the access details.
If a thief accesses the internet with the stolen laptop, Retriever will collect information on the internet
service provider in use, so that the police can be alerted to its location.
Thousands of laptops are stolen every year form homes and offices, but with the use of laptops increasing,
the number stolen while their owners are out and about has been rising sharply.
Other security software allows users to erase data remotely or lock down the computer.
B. to express the owners" anger to the thief
C. to remind the thief of this conscience
D. to make the thief give up his mind
B. help recognize the lost laptop
C. lock down the computer remotely
D. send a spoken message
B. turn on the laptop by using the original password
C. operate the laptop by means of an alternative password
D. erase the information kept in the stolen laptop
B. A new soft ware provides a means to reduce laptop theft.
C. Retriever has helped to find thieves and lost computers.
D. A new program offers a communication platform with the thief.
I.Q., a generally bad predictor of success. Instead, it"s purposeful practice. Top performers spend more hours
practising their craft. It you wanted to picture how a typical genius might develop, you"d take a girl who
possessed a slightly above average language ability. It wouldn"t have to be a big talent, just enough so that she
might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally
shared some similar qualities. Maybe the writer was from the same town, had the same family background,
or shared the same birthday.
This contact would give the girl a vision of her future self. It would hive her some idea of a fascinating
circle who might someday join. It would also help if one of her parents died when she was 12, giving her a
strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she would
read novels and life stories of writers without end. This would give her a primary knowledge of her field.
She"s be able to see new writing in deeper ways and quickly understand its inner workings.
Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising
in this way, he delays the automatizing process. Her mind wants to turn conscious, newly learned skills into
unconscious. Automatically performed skills. By practising slowly, by breaking skills down into tiny parts and
repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser
who would provide a constant stream of feedback, viewing her performance form the outside, correcting the
smallest errors, pushing her to take on tougher challenges. By now she is redoing problems-how do I get
characters into a room-dozens and dozens of times. She is establishing habits of thought she can call upon in
order to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius. It"s the ability to develop
a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great
achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and
what we"re "hard-wired" to do. And it"s true that genes play a role in our capabilities. But the brain is also
very plastic. We construct ourselves through behaviour.
B. the relationship between genius and success
C. the decisive factor in making a genius
D. the way of gaining some sense of distinction
B. join a fascinating circle of writers someday
C. share with a novelist her likes and dislikes
D. learn from the living examples to establish a sense of security
B. her writing turns into an automatic pattern of performance
C. she acquires the magic of some great achievement
D. she comes to realize she is "hard-wired" to write
B. A responsible adviser is more important than the knowledge of writing.
C. As to the growth of a genius, I.Q. Doesn"t matter, but just his|her effort.
D. What really matters is what you do rather than who you are.
