Vitamin B could help reduce the effects of the dangerous type of air pollution, according to a new study published on Monday. In the first study of its kind, a team of international researchers looked into the damage caused by one of the pollutants that have the severest impact on health¡ªPM2.5.

They found that Vitamin B supplement could effectively reduce the impact of the tiny particles £¨¿ÅÁ££©on the human body, although they stressed that the research was in its early stages. According to the WHO, 92% of the world's people are living in places where the PM2.5 level goes beyond the recommended level. So it¡¯s urgent to find a solution to the problem.

According to this study, published in the PNAS, 10 volunteers were initially exposed to clean air and given a placebo (°²Î¿¼Á£©to check their baseline responses. The group then kept on taking placebos tor tour weeks before being exposed to heavily polluted air from downtown Toronto, where an estimated 1,000 cars passed every hour. The bad air was delivered to the volunteers through an "oxygen type" face mask. The experiment was then repeated, with each volunteer taking a Vitamin B supplement daily, made up of 2.5mg of folic acid, 50mg of Vitamin B6, and l mg of Vitamin B12.

Vitamin B6 can be found in liver, chicken, nuts and other things, and Vitamin B12 in fish, meat, eggs, milk and some cereals. The researchers found that four weeks of Vitamin B supplements ¡ª the damage of PM2.5 effects by 28-76%. The results emphasized how prevention at an individual level could be used to fight against the damage of PM2.5, the researchers said.

1.What's the newly discovered effect of Vitamin B in Paragraph 1?

A. It can be used to replace other vitamins in our daily life.

B. It can help lower the air pollution level in the open air.

C. It can reduce the impact of PM2.5 on human bodies.

After the Earthquake had stopped, when the rescuers reached the ruins of a young woman¡¯s house, they saw her dead body through the cracks. But her pose was somehow strange that she knelt on her knees like a person was worshipping(Àñ°Ý); her body was learning forward, and her two hands were supported by an object. The collapsed house had crashed her back and her head.

With so many difficulties, the leader of the rescue team put his hand through a narrow gap on the wall to reach the woman¡¯s body. He was hoping that this woman could be still alive. However, the cold and stiff body told him that she had passed away for sure.

He and the rest of the team left this house and were going to search the next collapsed building. For some reasons, the team leader was driven by a compelling force to go back to the ruined house of the dead woman. Again, he knelt down and used his hand through the narrow cracks to search the little space under the dead body. Suddenly, he screamed with excitement, ¡°A child! There is a child!¡±

The whole team worked together; carefully they removed the piles of ruined objects around the dead woman. There was a 3-month-old little boy wrapped in a flowery blanket under his mother¡¯s dead body. Obviously, the woman had made a sacrifice for saving her son. When her house was falling, she used her body to make a cover to protect her son. The little boy was still sleeping peacefully when the team leader picked him up.

The medical doctor came quickly to examine the little boy. After he opened the blanket, he saw a cell phone. There was a text message on the screen. It said, ¡°If you can survive, you must remember that I love you.¡± This cell phone was passed around from one hand to another. Everybody that read the message wept. ¡°If you can survive, you must remember that I love you.¡± Such is the mother¡¯s love for her child!

Twenty years ago, the following news item probably wouldn¡¯t have made much sense to most Americans.

Muslims in Iran went to the streets today to support an ayatollah¢Ù¡¯s call for a revolution. Meanwhile, in Israel, Palestinian leaders urged support for the intifada¢Ú, ¢Ùleader ¢Ústruggle

These words come from Arabic, a language with which few Americans are familiar. Yet by 1990 these words were routinely used in both broadcast and print news. How did these words find their way into English?

Like all existing languages, English is continually changing. The adoption of foreign words into English vocabulary, called borrowing, is anything but a new phenomenon. In fact, it¡¯s been going on from the time the language first began to take shape around A. D. 450. English has been borrowing words from the conquered(±»Õ÷·þÕß), trading partners, immigrants, and a variety of other sources.

So when the events in the Middle East commanded the world¡¯s attention during the latter part of the twentieth century. English simply borrowed the words it needed to describe what was happening in that area. The more often such words were used, the less ¡°foreign¡± they sounded. Eventually, these borrowed words came to be used routinely in speech and writing.

Borrowed vocabulary from foreign language is not the only source of new words in English. As fresh ideas evolve and innovative technology are developed, new English words are created to describe them. These words may be words borrowed(WB) from other languages, existing words taking on new meanings(EWNM), acronyms, blends, compounds, or newly coined words, as the following examples and the chart show.

Kwanza

borrowed from Swahili: seven-day African-American cultural festival

rap

old word, meaning to knock quickly, taking on a new meaning; a form of music

AIDS

acronym for acquired immune deficiency syndrome

exercycle

blend of existing words: exercise + bicycle

skateboard

compound of existing words

cellulite

new word for fatty deposits on the hips and legs, coined in 1971

In the next four lessons, you¡¯ll be introduced to some of the history and mechanisms(Ìåϵ)that have shaped and continued to influence the language we use. Whether the words we speak are borrowed or created, they show a vital feature of English---adaptability. English is alive.

1.What does the word ¡°commanded¡± in the fourth paragraph probably mean?

A. Ordered B. Instructed

C. Controlled D. Drew

2.The word ¡°mouse¡± may belong to an example of __________.

A. WB B. EWNM

C. Acronyms D. Blends

3.Where does this text probably come from?

A. A cultural section of a newspaper

B. A language book review

C. A language course advertisement

D. A language lesson book

4.Which of the following can best cover the main idea of the passage?

A. The language in the media is changing

B. English has been borrowing words

C. English is a living language

D. A new phenomenon appears in English

Although people value intelligence¡ªunderstanding, reasoning, the ability to learn¡ªthey also respect wisdom, or the knowledge and experience that they gain over a lifetime. In some ways, wisdom is like beauty: we value it, we desire it, we know it when we see it, but it is nearly impossible to pin down such a nice quality. 1.

1. Working at being social.

Studies show that people who stay connected to others show higher levels of wisdom than those who remain alone. 2. Next time you¡¯re at a party or gathering, single out someone who¡¯s standing alone; and strike up a conversation.

2. 3.

Wisdom involves being able to understand all sides of an issue without letting personal feelings gel in the way. Owning your mind means realizing that everyone has a life story that influences their actions. During the course of every day, make a note of the issues that annoy you, and take a moment to see them from the other side.

3. Learning how to say ¡°I could be wrong¡±.

A wise person understands that it is impossible to know everything and that life is likely to take unexpected turns. 4. Admitting that there are times when you could be mistaken will go a long way in strengthening your fame.

4. Reading the news.

5. If you don¡¯t already read a daily paper or news online, start by going through a single front-page article from a major respected news source.

Almost everyone has the potential to become wiser, particularly if you strengthen these habits.

A. Practicing being open-minded.

B. Sharing good news with your friends.

C. But researchers have tried and here¡¯s what they¡¯ve found.

D. Recognizing your errors can lead only to even greater wisdom.

E. Make an effort to join a new club, or invite an old friend for coffee.

F. You do not have to admit your mistakes if you are really unwilling to.

G. You cannot make balanced choices unless you understand world circumstances.

Hi Maz and Bobby,

I don't know what you're up to this Sunday, but if you're at a loose end, come over to my place. We're going to have a barbecue.

Tom

Hi Tom,

Thanks mate, but I'm completely snowed under at the moment. I have to write an essay by Monday afternoon, so I'll be working all weekend. I've got nothing arranged for the following weekend though, so maybe we can meet then? I'll call you later.

Bobby

Dear Tom,

Like Bobby, I'm a bit tied up tomorrow. Unfortunately, I have to go to my great uncle's house for a family lunch. He was ill so we thought it might not happen, but it looks as if it's going ahead. I really can't get out of it because it's the old man's 60th birthday and most of the family will probably be there.

Maz

Ok you guys,

I'm calling off the barbecue. Judging from the grey sky, it's going to rain all weekend anyway. Maybe you'll have done your various duties by the end of the evening and we can go for a drink instead! If you want to relax, I'll be in The Hart, a pub on King Street. Gloria and I are meeting there at about 8:30, as long as nothing else pops up! Don't forget it closes at 10:30 on Sundays.

Ok, time to put my feet up and take it easy!

Later,

Tom
