     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.

1. Where is the first invention mainly designed to use?

A. On the traffic roads.
B. In parks and gardens.
C. On campus and the golf course.
D. In kindergartens

2. The car is charged ____.

A. with solar panels at the solar station
B. with solar panels on its top
C. through the wires at public places
D. through the wires at home

3. Where does the power of door light come from?

A. Electricity through wires.
B. Mechanical energy by opening and closing the door.
C. Sun panels on the building top.
D. Batteries charged before being used.

4. From the two inventions, we can see that ____.

A. students could design for the future
B. inventions are not so difficult
C. these inventions are valuable but not practical
D. inventions can't lack knowledge and money

1-4: C B B A

Don't talk to me．I'm busy with my iPhone．

　　Riding a London subway, a person from China will notice one major difference：in London, people do not look at each other．In fact, eye contact is avoided at all times．That's not rudeness－people are just too busy to bother looking．

　　Busy doing what, you ask? Well, they're certainly not using the time for a moment of quiet reflection(沉思)．Nor are they reading a book．New technology has replaced quiet habits．Today the only acceptable form of book on the London Underground is an e-book．

　　Apple must earn a fortune from London commuters(乘车上下班的人)．Since the launch of the iPhone in 2007, over 40 000-yes, that's 40 000--" apps"(programs downloaded for the iPhone)have been designed．

　　Commuters love them because they are the perfect time-filler．One" app", called iShoot, is a game that features tanks．Another one, Tube Exits, tells passengers where to sit on the train to be closest to the exit of their destination(目的地)ISteam clouds the iPhoue screen when you breathe into the microphone．You can then write in the" steam" on your phone screen．

　　For those without an iPhone, another Apple product, the iPod, may be the distraction(消遣)of choice．It's not just teenagers who"plug in" to their music--iPods are a popular way to pass the time for all ages．

　　And if games e-books and music aren't enough to keep you occupied．Then perhaps you would prefer a film? The development of palm DVD technology means many commuters watch their favorite TV show or film on the way to work．With all this distraction, it's amazing that people still remember to get off the train．

     Don't you think your schoolbag is too heavy to bear? The e-schoolbag will free you from
the weight.
     It is said that e-schoolbags are going to be brought into use in Chinese middle schools
soon. An experiment with several hundred e-schoolbags will begin in seven cities: Beijing,
Shanghai, Dalian, Shenzhen, Chongqing, Taiyuan and Shijiazhuang. And the e-schoolbags
are going to cover all over China if the experiment shows to be successful. In fact, the
e-schoolbag should perhaps be called an e-notebook. It is a small hand-held computers
for school students.
     Heavy schoolbags have long been a serious problem for school students. The average
schoolbag of middle school students weighs up to 5 kilos. But the e-schoolbag will change
everything. It is much lighter than a usual schoolbag, weighing under 1 kilo.
     Also, it is no bigger than a usual book, but it can still hold all the things for study, such
as a textbook, a notebook and exercise book. They could be made into chips that are as
small as a stamp. The students can read the text page by page on the screen. They can
still take notes using a special electronic pen. If they want to know the meaning or the
pronunciation of a new word, or even e-mail their teachers, it's just a press of a button.
     In some foreign countries, it is becoming common. But it is hard to tell when people
will receive this new form of study. Some say that e-textbooks can easily be broken,
some say that it is not good to students' eyesight to look at the screen for long.But only
time will tell.

1．The e-schoolbag has many functions EXCEPT _______.

A. It can pronounce the words.
B. It can send e-mails.
C. It can be used as a dictionary.
D. It can phone somebody.

2．According to the passage, the e-schoolbags _______.

A. are not heavy as before but still large
B. are used as an experiment in Tianjin
C. are made of metal
D. are going to cover China if it shows to be successful

3．Which of the following statement is TRUE?

A. All the students in China will use this new schoolbag.
B. We can do a lot of work based on the programmers of the chips.
C. The e-notebooks are very perfect.
D. We will not make notes because the e-notebook can make all by itself.

4．Which of the following can be the general title of the passage? ______

A. An Experiment In China
B. Please Change Your Schoolbag
C. A New Invention, A New Schoolbag
D. Chips

     Don't_believe_all_of_the_stereotypes(模式化的形象)you_may_have_heard_about_Americans.Even the ones that are true in general may not be true about specific individuals or a large part of the population.For example,although Americans tend to be louder than people from other cultures(especially at athletic
events),many of the people you meet will be quiet and polite.Some people may be intolerant, but most will be pleasant and welcoming.Remember that American films and television exaggerate(夸张)in order to
generate excitement, and so present a rather false picture of what life in the United States is really like.
Therefore,tourists in the US are not always on their best behavior.
     Americans do tend to be more informal than people from other countries.It is common for Americans
to wear casual clothing to school and to greet professors by first name.However, good manners and
politeness are always appreciated.If you are polite, and dress a little more formally than your American
friends, it will not be poorly thought of.
     However,some businesses require their employees to wear a uniform or a suit.It would be improper to wear a Tshirt and blue jeans to a job interview.Some of the more prestigious restaurants require a coat and a tie.Americans tend to dress up for cultural events(the opera,theater and ballet)and to dress down for
athletic events.Formal wear is required at weddings and funerals, or any other event with religion.If you
rely on the stereotypes,you will likely put yourself into an embarrassing situation.

1. The underlined sentence probably means________.

A. some of the stereotypes you may have heard about Americans are not true
B. you should not believe the stereotypes you may have heard about Americans
C. none of the stereotypes you may have heard about Americans should be believed
D. none of the stereotypes you may have heard about Americans should not be believed

A. most Americans are polite
B. people who are polite are welcome
C. casual clothing makes others uncomfortable
D. American students are impolite to their teachers

     Don't make sudden changes. Start slowly, by waking just 15 to 30 minutes earlier than usual. Get used to this for a few days. Then cut back another 15 minutes. Do this gradually until you get to your goal time.
Sleep earlier. You might be used to staying up late, perhaps watching TV or surfing the Internet. However, you just might fall asleep much sooner than you think.
     Put your alarm away from your bed. You have to get up out of bed to shut it off. By then, you're up.
Now you just have to stay up.
     Go out of the bedroom as soon as you shut off the alarm. Don't find an excuse to go back to bed. My
habit is to force myself into the bathroom. By the time I've washed my hand, and the toilet of course, and
looked at my ugly face in the mirror, I'm awake enough to face the day.
     Allow yourself to sleep in once in a while, as long as it's not a regular thing. I do it maybe once a week or so.
     Make it a reward. At first you're forcing yourself to do something hard, but if you do something
pleasurable as part of your morning routine, soon you will look forward to waking up early. My reward used to be to make a hot cup of coffee for myself and read a book. Now I look outside (or better yet, get
outside!) and watch the sky turn light. It's beautiful. It's now my favorite time of day.
Getting up early is a reward in itself for me and so will it be for you.

1. Which of the following does the writer suggest we do?

A. Get up at our goal time to start the new habit.
B. Shut off TV and the Internet, and face the day.
C. Get up at the same time every day to keep the habit.
D. Do something enjoyable in the morning to begin the day.

2. We should get into the bathroom right after we get out of bed because________.

A. that is part of our routine
B. we really need a cold wash
C. the alarm clock needs to be shut off
D. that will make ourselves completely awake

3. The writer enjoys ________most in the morning.

A. doing some washing
B. making a cup of coffee for himself
C. watching the daybreak
D. sleeping late, and thinking in bed

4. This passage is written to________.

A. share the writer's experience
B. give tips for becoming an early bird
C. persuade people to get up early
D. help get rewards from getting up early
