A
There are two interesting news items in the paper a few years ago.One was about a man who received a bill from the telephone company for $999,999—for three months！The other was about a man who received $2,000 for doing nothing.
The connection between the two news items is simple：computers—the best invention of the twentieth century.The telephone bill came from a computer which made a terrifying mistake：the man’s bill was only $23.36.The other item was not so amusing.A man walked into the unguarded computer room of a large packaged room of company and expertly programmed the computer to pay him $2,000 a month for raw meat which he “supplied”to the company.Of course he never sent the meat，but he certainly received the money.The computer wrote out a bill，and even “signed” it.It was only a random(随便的) check that uncovered the trick.It could be happening in thousands of other companies all over the world.
Computers are not the magic workers that some people say they are.They make mistakes，they are sometimes slower than human beings and they are easily fooled.The US used to conscript(征兵) people with the help of a computer.The army sent out a card，which had to be filled in and sent back.It was easy to avoid being called up(应征入伍) simply by spreading candle—wax on the card.The computer couldn’t read the card，and did nothing with it.
It’s in our everyday life that computers cause many problems.Let’s get back to using people instead of computers，before a mistake that we can’t put right. 1．In the first paragraph we know ________.
A．the paper is telling a lie
B．the first sentence is the topic sentence C．the two news items made people surprised
D．if a man did nothing at all for the telephone company，he would still get $2,000 2．The man was given $2,000 because ________.
A．the computer made a big mistake B．he worked very hard
C．he programmed the computer to pay him so much for raw meat D．his work was very difficult to do and the pay was certainly high 3．The main idea of the second paragraph is ________.
A．computers are magic workers B．computers can do anything as man
C．computers can write out a bill and even “sign” it D．computers sometimes also make big mistakes 4．The writer’s main idea is that ________.
A．we’d better use people instead of computers in our everyday life
B．we should not use computers because they always make mistakes C．computers are widely used in our everyday life D．if we want to work well，don’t use computers
B
For thousands of years，we have looked for ways to measure time.Early humans found that the regular movements of the sun，the earth，the moon，and the stars made good ways to measure time.The rising and setting of the sun were used to distinguish day from night.
But，eventually，people needed to tell time more accurately，or exactly.So，by using the sun’s position in the sky，they divided the day into dawn，morning，midday and evening.
Then it was noted that the sun cast a changing shadow as it moved across the sky.Time could be told more accurately by setting up a stick and marking the positions of the sun’s shadow.It was the ancient Greeks who divided each position of this “sundial(日晷)” into hours.
But the sun doesn’t always shine.So，for the past 6,000 years，many other ways of keeping time have been tried.Slowburning candles were divided into hours，and the hourglass was invented.When all the sand in the top of an hourglass has shifted to the bottom，an hour has passed.
Later，the pendulum(摆钟)，with its regular backandforth movement of weights，was used to move the hands on a clock.Pendulums are still used in grandfather clocks.
Today，even more accurate clocks are in use，such as batteryoperated quartz clocks，digital clocks，and clocks run by electrical tuning forks and tiny atoms.These atomic clocks are the most accurate clocks ever invented.The exact time can be kept to within 1 second a century.
5．Humans in the old days used ________ to tell day from night.
A．the rising and setting of the sun B．batteryoperated quartz clocks C．atomic clocks D．digital clocks
6．A sundial works by ________.
A．tracking the movement of the stars around the sun B．marking a shadow cast by the moving sun C．burning candles in the sunlight D．watching the stars
7．Which of the following was NOT used in the past to measure time?
A．An hourglass. B．A sundial. C．Digital clocks. D．A pendulum.
8．Which of the following ways of measuring time is ordered from the least accurate to the most accurate?
A．Sundial，pendulum，sun.
B．Atomic clock，quartz clock，sundial. C．Sun，pendulum，atomic clock.
D．Digital clock，hourglass，slowburning candles.

Every part of the United States has special holidays depending on the particular national groups that live in the area.In Hawaii，there are many people of Asian ancestry (祖先，世系)．The Asians left rich traditions for these people to follow.Today，Hawaiians honor their ancestors with special feasts and festivals.
For people of Japanese ancestry in Hawaii，the Obon Festival is very special.It’s the ceremonies to honor the dead relatives and friends.They take place in July and August.People gather in the courtyards，dressed in traditional clothes.To the music of drums，men and women perform their native folk dances in honor of the dead.In the evening there are further ceremonies by the seashore.People place paper lanterns on tiny wooden boats，which represent the souls of the dead.They set hundreds of these boats in the water and watch as they float out over the dark ocean.
ChineseHawaiians celebrate the Moon Festival to honor their ancestors and their native land.They do this in August.Family members gather in a garden or a large open space in the light of the moon.They drink tea and eat delicious moonshaped cakes.The cakes represent an event in Chinese history.A long time ago，the people in China used round cakes in a special way—they sent secret messages to each other in cakes.The messages called for the people of the country to join together to fight against the bad king who ruled them at that time.The trick worked and the people were able to overthrow (推翻) their ruler.
By recalling this event on the Moon Festival，the Chinese people help to keep their traditions alive and their family ties strong. 9．The Obon Festival is held ________.

Laptop computers are popular all over the world.People use them on trains and airplanes，in airports and hotels.These laptops connect people to their workplace.In the United States today，laptops also connect students to their classrooms.
Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want.Within five years，each of the 1,500 students at the college will receive a laptop.The laptops are part of a $10 million computer program at Westlake，a 110yearold college.The students with laptops will also have access to the Internet.In addition，they will be able to use emails to “speak” with their teachers，their classmates and their families.However，the most important part of the laptop program is that students will be able to use computers without going to computer labs.They can work with it at home，in a fastfood restaurant or under the trees—anywhere at all!
Because of the many changes in computer technology，laptop use in higher education，such as colleges and universities，is workable.As laptops become more powerful，they become more similar than desktop computer.In addition，the portable computers can connect students to not only the Internet but also libraries and other resources.State highereducation officials are studying how laptops can help students.State officials are also testing laptop programs at other universities.
At Westlake College，more than 60 percent of the staff use computers.The laptops will allow all teachers to use computers in their lessons.As one Westlake teacher said，“Here we are in the middle of Virginia and we’re giving students a_window_of_the_world.They can see everything and do everything.” 13．Why is the word “speak” in the second paragraph in quotation marks?
