We know the famous ones — the Thomas Edisons and the Alexander Graham Bells — but what about the less famous inventors? What about the people who invented the traffic light and the windshield wiper(雨刮器)? Shouldn’t we know who they are?
Joan Mclean think so. In fact, Mclean, a professor of physics at Mountain University in Range, feels so strongly about this matter that she’s developed a course on the topic. In addition to learning “who” invented “what”, however, Mclean also likes her students to learn the answers to the “why” and “how” questions. According to Mclean, “When students learn the answers to these questions, they are better prepared to recognize opportunities for inventing and more motivated to give inventing a try.”
Her students agree. One young man with a patent for an unbreakable umbrella is walking proof of Mclean’ statement. “If I had not heard the story of the windshield wiper’s invention,” said Tommy Lee, a senior physics major, “I never would have dreamed of turning my bad experience during a rainstorm into something so constructive.” Lee is currently negociating to sell his patent to an umbrella producer.
So, just what is the story behind the windshield wiper? Well, Mary Anderson came up with the idea in 1902 after a visit to New York City. The day was cold and stormy, but Anderson still wanted to see the sights, so she jumped aboard a streetcar. Noticing that the driver was struggling to see through the snow covering the windshield, she found herself wondering why there couldn’t be a built-in device for cleaning the window. Still wondering about this when she returned home to Birmingham, Alabama, Anderson started drafting out solutions. One of her ideas, a lever(操作杆) on the inside of a vehicle that would control an arm on the outside, became the first windshield wiper.
Today we benefit from countless inventions and innovations. It’s hard to imagine driving without Garrett A. Morgan’s traffic light. It’s equally impossible to picture a world without Katherine J. Blodgett’s innovation that makes glass invisible. Can you picture life without clear windows and eyeglasses?
1.By mentioning “traffic light” and “windshield wiper”, the author indicates that countless inventions are ________.
A. beneficial, because their inventors are famous
B. beneficial, though their inventors are less famous
C. not useful, because their inventors are less famous
D. not useful, though their inventors are famous
2.Professor Joan Mclean’s course aims to ________.
A. add colour and variety to students’ campus life
B. inform students of the windshield wiper’s invention
C. carry out the requirements by Mountain University
D. prepare students to try their own invention
3.Tommy Lee’s invention of the unbreakable umbrella was ________.
A. not eventually accepted by the umbrella producer
B. inspired by the story behind the windshield wiper
C. due to his dream of being caught in a rainstorm
D. not related to Professor Joan McLean’s lectures
4.Which of the following can best serve as the title of this passage?
A. How to Help Students to Sell Their Inventions to Producers?
B. How to Design a Built-in Device for Cleaning the Window?
C. Shouldn’t We Know Who Invented the Windshield Wiper?
D. Shouldn’t We Develop Invention Courses in Universities?

The London Underground (The Tube)
The main source of public transport in London revolves around the Underground (or the Tube as it is known to Londoners). This network of 12 lines can get you to most places in the center of the city quickly.
It’s most necessary to get an Oyster Card or a Travelcard. Single tickets are priced starting at the intentionally absurd (荒谬的) price of £ 4.80 (Zone 1-3), if you pay cash. Using an Oyster card, a single fare is £ 2.30 if you are traveling within the central Zone 1.
On hot days it is also advisable to take a bottle of water with you as Underground trains are not air-conditioned.
Last trains leave central London at around 00:30 weekdays, 23:30 Sundays. First trains leave the suburbs at around 5:00.
The Bus System
Outside the center of London, Tube stations are farther apart, so buses help fill the gaps. Also, the bus offers a cheaper alternative, even if it is a slower journey.
Cash fares for London buses have been abolished — you cannot pay cash. A bus fare costs £ 1.50 if using only buses, the fare is capped at £ 4.40 per day for Oyster or contactless users.
River Services
There are a number of different routes along the River Thames. The faster commuter services operate all day from Greenwich Pier to Embankment and from Putney and Chelsea harbour to Blackfriars during Peak Hours only. These routes will pass a number of places of interest including the Houses of Parliament and London Bridge. A return fare from Putney to Blackfriars will cost about 12 pounds.
National Rail
Once you leave Central London or if you are traveling South of the River Thames, the best public transport option will often be National Rail. There are numerous connections to the Rail System from the Tube. Travelcards can be used for travel on the National Rail (but not the Heathrow Express). Oyster cards can be used up to Zone 6 except certain services including Heathrow Express, Heathrow Connect and HSI.
1.When taking the London Underground, ________.
A. you should buy tickets with cash
B. you can save more money with a single ticket
C. you can go to any place in London quickly
D. you are advised to take a bottle of water along on hot days
2.If you use river services along the River Thames, you will pass ________.
A. London BridgeB. Stratford
C. Canary WharfD. Tower Hill
3.To travel South of the River Thames, it is recommended that you use ________.
A. The London UndergroundB. The Bus System
C. The DLR and the TramD. National Rail

Maybe ten-year-old Elizabeth put it best when she said to her father,“But,Dad,you-can’t-be-healthy-if-you’re-dead.”Dad,in a hurry to get home before dark so he could go for a run,had forgotten to wear his safety belt—a mistake 75% of the US population makes every day.The big question is why.
There have been many myths about safety belts ever since their first appearance in cars some forty years ago.The following are three of the most common.
Myth Number One:It’s best to be “thrown clear” of a serious accident.
Truth:Sorry,but any accident serious enough to “throw you clear”is also going to be serious enough to give you a very bad landing.And chances are you’ll have traveled through a windshield(挡风玻璃) or door to do it.Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are “thrown clear”.
Myth Number Two:Safety belts “trap” people in cars that are burning or sinking in water.
Truth:Sorry again,but studies show that people knocked unconscious(无知觉的) due to not wearing safety belts have a greater chance of dying in these accidents.People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situation,not to be trapped in them.
Myth Number Three:Safety belts aren’t needed at speeds of less than 30 miles per hour(mph).
Truth:When two cars traveling at 30 mph hit each other,an unbelted driver would meet the windshield with a force equal to diving head first into the ground from a height of 10 meters.

Dear Grace,
How is everything going with you?
I’ve been in Russia for two months. This is the first time that I’ve been away my family for such a long time. With the help of Katia, a roommate of me, I soon get used to live without my parents around. Katia, like many other Russian girls, are nice and lively. We became friend shortly after we met each other. Although her English is a little hardly to understand, we enjoy chatting and we usually talk a lot about our own family. We’re both surprising that Chinese culture and Russian culture were so different. Now, we are planning a small party for the next Sunday. There, Katia will introduce me to some of her friends, one of who has been to China several times. I just can’t wait.
Write back to me as soon as possible.
Yours,
Betty

A new book called “Battle Hymn of the Tiger Mother” by Amy Chua has caused a debate (争论) about cultural differences in parenting. Amy Chua is a teacher in an American university and both of her parents are Chinese. In the book, Ms. Chua writes about how she taught her daughters. She told NBC television that she had a clear list of what her daughters were not allowed to do, such as having a play date, watching TV or playing computer games and getting any grade less than an A.
Many people are against Amy Chua’s parenting style (风格), even her husband, who is American. They say it is rude and unfair to children. But she says her parents raised her and her three sisters in that way.
Ms. Chua says after her younger daughter shouted “I hate my life! I hate you!” she decided to retreat because she was afraid of losing her daughter. But she also says American parents often have low expectations of their children’s abilities.
“The debate is about what it means to be a successful parent and what it means to be a successful child,” said Stacy DeBroff, who has written four books on parenting. She says Amy Chua’s parenting style is not limited to Chinese families. It is a traditional way of parenting among immigrants (移民). They hope to get a better future for their children.
She also sees a risk (风险). When children have no time to be social or to develop their own interests, they might not develop other skills that they need to succeed in life. DeBroff advises parents to develop their own style of parenting and not just repeat the way they were raised.
1.Which of the following words can best describe Amy Chua?
A. Polite.B. Cruel.C. Strict.D. Popular.
2.The underlined word “retreat” in Paragraph 3 is closest in meaning to _____.
A. give upB. go onC. go outD. give out
3.According to Ms. DeBroff, _____.
A. Amy Chua’s parenting style should be forbidden
B. Americans should learn from Amy Chua
C. parents should have their own parenting style
D. Amy Chua’s style is bad for children’s growth
4.In which part of a newspaper can you read the passage?
A. Business.B. Entertainment.C. Sports.D. Culture.
