Have you ever heard of blogs (博客)? If you haven’t, you should have. It’s here, it’s growing and it’s having an influence on our life. Surf the Internet and you’ll find blogs everywhere. A blog, shortened from “weblog”, is a public Internet journal written by one person or a group of people. It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are “published”, so other people can read them.
Authoring a blog, maintaining a blog or adding an article to an existing blog is called “blogging”. Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as “text and photos” in a blog can be called “blog posts”, “posts”, or “entries”. The person who posts these entries is called a “blogger”.
Now, somewhere around the world, a blog is created almost every 6 seconds. Because it’s great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He’s trying to make blogs the important tools for future business communications.

Switzerland(瑞士) is famous for its watches。 However, this country didn’t invent the watch。It was the British who did it。 Here is a story of how the watch was brought to Switzerland。
Many years ago , an Englishman was travelling to Italy 。 On his way he stopped in a small town in South Switzerland。 This Englishman travelled in a carriage(马车) inside which there was a carriage watch。 This was the earliest kind of watch。 A native shop assistant (售货员) happened to see the watch 。 He wondered what it was and asked the Englishman about it。 “ It is a carriage watch 。” said the man 。 This machine tells the time but now it isn’t working 。
At once the shop assistant offered to try to repair it 。 So the traveller handed him the watch。 The assistant was a very wise man 。 So it was not surprising that he managed to repair it 。 He even remembered how it was made。 As soon as the traveller had gone on his way , he made a watch exactly the same type。
Thus the watch-making was started in Switzerland。 Today Swiss watches are sold in stores all over the world。

Mackenzie told Berry that her phone --- it wasn’t cordless (无绳的) --- wouldn’t reach into the cupboard. “Will the phone reach under your bed?” Berry asked 6 . “No,” Mackenzie said.

“Can you hide under a 7 and pull your bedspread over you?” That’s 8 what Mackenzie did. She hid under her blanket, holding the phone and listening to Berry’s voice.

Berry talked quietly, which 9 Mackenzie. It helped, too, when Berry told her to think of something 10 . “Try not to cry,” Berry told Mackenzie during the call. “ I know it’s 11 . Do you have something you can hold onto?” Mackenzie struggled to 12 tears. She couldn’t 13 anything without showing her hiding spot. “ It’s OK,” Berry said. “You’ve got me here with you.”

“He’s in my room,” Mackenzie 14 . “Now be quiet, OK? Just don’t talk,” Berry said. For much of the call, Berry dropped her voice to a whisper, 15 the intruder (闯入者) might hear her voice over the phone. 16 , the man came into her room, then left.

Berry told Mackenzie that the 17 were on their way. Minutes later, they arrived and 18 one man in the backyard and another man in a getaway car.

On Thursday morning, the Emergency Communications Bureau gave Mackenzie its Hero Award for her 19 . Berry also received high praise. And then it was off to school for Mackenzie. But first Berry had something to 20 to the middle-schooler: a cordless phone.

Television will turn 86 years old on September 7, 2013, and it has never looked better. In its youth, television was a piece of furniture with a tiny, round screen showing unclear pictures of lowbudget programs. In spite of its shortcomings, it became well-received. Between 1950 and 1963, the number of American families with a television jumped from 9% to 92% of the population.

As the audience got larger, the technology got better. Television sets became more reliable through the 1960s. Both of the reception and the picture improved. The major networks started broadcasting programs in color.

Even greater improvements were coming according to Sanford Brown, who wrote an article for the Post in 1967. Surprisingly, just about every prediction he made in the article became a reality. For example: All sets in the notdistant future will be color instruments. He also predicted that TV sets would become smaller, simpler, more reliable and less expensive and may forever put the TV repairman out of work. Smaller sets do not, of course, mean smaller screens. TV engineers expect screens to get much bigger. However, today's 3D TV is even farther away, if it's coming at all. There is some doubt whether the public would be eager to pay for it, in view of people's cold reception given to 3D movies.

But the technology with the greatest potential, according to Brown, was cable television (有线电视), which was still in its early stages then. As he predicted, the future of cable television was highly interactive. It wasn't cable television that gave Americans their electronic connection to the world, however. It was the Internet. He even foresaw the future office: using picture phones, bigscreen televisions for conferences, and computers providing information, at the touch of a button.

Brown ever said, “The future of television is no longer a question of what we can invent. It's a question of what we want.”

1.What can we infer about television sets in the 1960s?

A．They were very popular with Americans.

B．Their appearance remained unchangeable.

C．They showed blackandwhite pictures.

D．Their pictures were of poor quality.

2.Which of the followings did Sanford Brown fail to predict?

A．Television's good quality.

B．The invention of 3D TV.

C．The more functions of TV.

D．The potential of cable TV.

3.From the passage we know _________.

A．TV will certainly take the place of computers

B．There won’t be further improvement on TV

C．TV repairmen will be out of work in the future

D．3D movies don’t appeal to people very much

4.What is the text mainly about?

A．The shortcomings of television.

B．The advantages of television.

C．The development of television.

D．The invention of television.

One genetic mutation(基因突变)occurs on average for every 15 cigarettes that a typical lung-cancer patient smokes, according to a study that has found for the first time all of the mutations happen during the lifetime of a cancer patient.

Scientists have completed a full genetic examinations of the genomes（基因组） of cancer patients, and hope the information will lead to a basic understanding of the causes of cancer—and possibly drugs and treatments—by making out the mutations that turn a healthy cell into a cancerous tumor cell.

They studied a lung-cancer patient who had about 23,000 DNA mutations in his lung cells that were connected with exposure(暴露) to the toxins found in cigarette smoke and had built up over his lifetime.

They also looked at a patient with malignant melanoma(恶性黑色肿瘤), the most dangerous form of skin cancer, who had got 30,000 special mutations known to be connected with exposure to sunlight.

Scientists believe this new finding into the genetics of cancer will finally lead to new drugs and perfect treatments that aim at the specific changes to the gene that cause the disease, as well as new techniques for discovering following cancers that have escaped from treatment in other parts of the body.

“For the first time, we have a complete map of all mutations in a cancer cell,” said Dr. Peter Campbell, who led the Cancer Genome project to work out the whole DNA system of tumor cells in order find the mutations.

A similar method was performed on the cells of a patient with skin cancer, which is how the researchers were able to show that the malignant skin cells contained changes that resulted from exposure to light.

“These are the two main cancers in the developed world for which we know the chief exposure. For lung cancer it is cigarette smoke, and for malignant melanoma it is exposure to sunlight,” Professor Campbell said.

1.What can the genetic examination of the genomes of cancer patients be used for?

A.To help the professors to win the Nobel Prizes.

B.To advance the study of reason and cure of cancer.

C.To make the medicine industries earn more money.

D.To help the cancer patients reduce their pain.

2.The underlined word in the third paragraph can be placed by_____.

A.smoke B.sunlight C.cell D.poison

3.Which of the following statements is right according to the passage?

A.The lung-cancer patient had 30,000 mutations in his lung cells.

B.The genetics of cancer will finally lead to new drugs soon.

C.It’s the first time that people mapped mutations in a cancer cell.

D.Dr. Peter tries to invent a new drug with the DNA system.

4.What’s the similarity between malignant melanoma and skin cancer of patients?

A.Their smoking too much in daily life.

B.Their receiving too much sunshine.

C.Their refusing to accept treatment.

D.Their interest in travelling abroad.
