Technology is the application of knowledge to production. Thanks to modern technology, we have been able to increase greatly the efficiency of our work force. New machines and new methods have helped cut down time and expense while increasing overall output. This has meant more production and a higher standard of living. For most of us in America, modern technology is thought of as the reason why we can have cars and television sets. However, technology has also increased the amount of food available to us, by means of modern farming machinery and animal breeding techniques, and has made our life span longer via medical technology.

Will mankind continue to live longer and have a higher quality of life? In large measure, the answer depends on technology and our ability to use it widely. If we keep making progress as we have over the past fifty years, the answer is definitely yes. The advancement of technology depends on research and development, and the latest surveys show that the united States is continuing to put billions of dollars annually(每年) into such efforts. So while we are running out of some limited resources, we may well find technological substitutes (代用品) for many of them through our research programs.

Therefore, in the final analysis, the three major factors of production (land, labor and capital) are all influenced by technology. When we need new skills or techniques in medicine, people will start developing new technology to meet those needs. As equipment proves to be slow or inefficient, new machines will be invented. Technology responds to our needs in helping us improve our standard of living.

How to Pick a Great Book to Read

The world is full of great books, just waiting to be read. How can you pick one you'll really like? Here are some tips:

● What makes you happy?

1. Are you really into dinosaurs or dogs or a specific person? Are there a few careers you're interested in? You can find books about almost anything you like, and you're more likely to enjoy reading a book if you're already interested in its subject.

● Fact or fiction?

Some books are entirely made up and imagined. Those are called fiction books. Novels, short stories are all examples of fiction. These books can transport you to another world or help you imagine something beyond your own experience.

Non-fiction books give you the who, what, when and why. 2. Non-fiction books can bring everything to life from the first trip to the moon to what it's like to explore the deepest oceans. Try both fiction and non-fiction books to see which you like better.

●Find a family favorite.

What was your mother's favorite book when she was your age? Or your dad's? 3. Then you can talk about what they liked about it and share your thoughts. It's a fun way to get to know your family a little better, and to find a book you'll enjoy!

● Ask an expert.

4. Tell a librarian about your interests—rock stars, sports teams, historical events, whatever you're into—and the names of some books you already like. Your librarian can help you find other books that you're sure to love.

● Launch a book swap.

5. It's always fun to see what your friends are reading. Even if they're not exactly bookworms, you can all encourage each other to read and share books and authors you like. You also can look for book swaps in your area. It's a great way to build your personal library for free!

A. Ask them and give it a read.

B. Many of them read novels from start to finish.

C. Why not get some friends together and trade favorite books?

D. If you have a favorite hobby, look for books about that activity.

E. They tell stories using facts—but that doesn't mean they're boring.

F. Read the passage and decide for yourself whether it seems knowledgeable.

G. Your local library is a great place to find books that you'll love, and you don't have to search all by yourself.

People always think men are more skilled than women in driving. Nowadays women appear to have a positive image of themselves as safer drivers than men.

In a survey done for insurer MetLife, 51% of women said they drive more safely. The evidence is on their side: Men are 3.4 times more likely than women to get a ticket for careless driving and 3.1 times as likely to be punished for drunk driving. “Women are on average less aggressive and more law abiding (守法的) drivers, which leads to fewer accidents.” the report says. However, not all male drivers share the same opinion. Of the men surveyed by MetLife, 39% claimed male drivers were safer. The findings did back them up on one point: automotive knowledge. The report showed that more men are familiar with current safety equipment such as electronic stability control, which helps prevent rollover accidents.

Auto safety unavoidably matters to money. Insurance companies focus on what classes of drivers have the lowest dollar amounts of claims, and for now, that mainly includes women. In general, women pay about 9% less for auto insurance than men. A study by the website Insweb also showed that auto insurance rates are lower for women in most states. Among individual states, women get the greatest advantage in Wyoming (where they pay 20% less), South Dakota and Washington, D. C., where their insurance costs are 16% lower.

“More than 11,900 male drivers died in U.S. traffic accidents in 2009, compared with just under 4,900 women drivers,” according to the study. “Based on miles traveled, men died at a rate of 2.5 deaths per 100 million miles traveled, v.s. 1.7 deaths for women.”

1. According to the study, male drivers _________.

A. are less aggressive while driving

B. are more skilled at auto knowledge

C. are more likely to stick to driving laws

D. are less familiar with safety equipment

2. Insurance companies focus on female driver clients(客戶) probably because they _________.

A. cause more accidents on the road but ask for little

B. cause little damage and pay more money to the insurance companies

C. make up the most part of the insurance clients

D. are more careful drivers and cause less damage

3. We can infer from the passage that _________.

A. men are 3.1 times more likely to get tickets than women

B. all women in the USA pay the same for their auto insurance

C. more female drivers die every year than male drivers

D. women are generally safer drivers than the opposite sex

4. The writer mainly develops paragraphs by _________.

A. giving examples B. making comparisons

C. drawing a conclusion D. presenting an argument
