Warmer sea temperatures could worsen the widespread destruction of coral reefs that hit the Caribbean in 2005,scientists fear.
In the waters around the US Virgin Islands,as much as 40 percent of coral died in some reefs last year,and the coral that survived probably isn't healthy enough to survive another hot summer,said Caroline Rogers,a US Geological Survey biologist.
Reefs are vital habitat for fish,lobsters and other sea life that feed and breed in the sheltered waters. The reefs also change storm waves that might otherwise wash away the beaches that are at the heart of the region's multibilliondollar tourism industry.
"You don't know how scary it looks down there," said Zandy Starr,who monitors coral and sea turtles in St. Croix's national parks. "All of us thought that by now,with all the cooler temperatures in January and February,we would have seen recovery,but they're still sick."
Glassy,calm seas have permitted coralkilling ultraviolet (紫外線的) rays to access to the ocean floor,warming water temperatures and making the fragile (易碎的) undersea life more sensitive to disease,Starr said.
Scientists haven't pinpointed (準(zhǔn)確地說出) what caused coral to become sick or led to the warm water,which stresses coral and makes it more susceptible (敏感的) to disease. They can't say whether global warming is a factor.
"We don't really have the data. You need a record over decades. There's a lot of research that needs to happen”,said Alberto Sabat,a biology professor at the University of Puerto Rico.
But the trend of warmer waters isn't limited to the Caribbean. The National Oceanic and Atmosphere Administration said waters were warmer than usual in the South Pacific,mid-Atlantic and Indian Ocean in mid-April.
Rogers said coral grew far better after hurricanes that devastated (摧毀) the US Virgin Islands in 1989 and 1995 because the storms cooled the sea,allowing reefs to recover relatively quickly from damage.
Rising temperatures appear to be "something new that the corals aren't used to," said Tyler Smith,a marine researcher at the University of the Virgin Islands.
The scientists worry that the problem is being overlooked,
"People just don't know that much about coral because it's underwater. If 40 percent of the trees ill one of our national parks died,people would take notice”,Rogers said.

What sort of life will you be living 39 years from now? Scientists have looked into the future and they can tell you. It looks as if everything will be so easy that people will probably die from boredom. You will be going around in some vehicles at 200 miles an hour and you will think nothing of taking a fortnight's holiday in outer space.
Your house will probably have air walls,and a floating roof,adjustable to the angle of the sun. Doors will open automatically,and clothing will be put away by remote control. The heating and cooling systems will be built into the furniture. You'll have a home control room― an electronics centre,where messages will be recorded when you're away from home. This will play back when you return,and also give you up-to-the-minute world news,and write down your latest mail. You'll have wail-to-wall global TV,an indoor swimming pool,TV-telephones and room-to-room TV.
The status symbol of the year 2000 will be the home computer help,which will help mother tend the children,cook the meals and issue reminders of appointments.
Cooking will be in solar ovens with microwave controls. Food won't be very different from 1961,but there will be a few new dishes―instant bread,foodless foods ( minus nutritional properties) ,juice powders and so on.
At work,dad will operate on a 24-hour week. The office will be airconditioned with pleasant smell and extra oxygen to give a physical and psychological lift. Mail and newspapers will be reproduced instantly anywhere in the world by facsimile (傳真) .There will be machines doing the work of clerks,shorthand writers and translators. Machines will "talk" to each other.
It will be the age of pressbutton transportation. Rocket belts will increase a man's step to 30 feet,and bustype helicopters will travel along crowded air ways. There will be moving plasticcovered pavements,200 mph. monorail trains operating in all large cities. The family car will be soundless and the engine will be smaller than a typewriter. Cars will travel overland on an 18 inch air cushion. Railways will have one central operator,who will control a whole nation's traffic. Jet trains will be guided by electronic brains.
By the year 2020,five percent of the world's population will have emigrated into space. Many will have visited the moon and beyond.
Our children will learn from TV,recorders and teaching machines. They will get pills to make them learn faster.
We shall be healthier,too. There will be no common colds,cancer,tooth decay or mental illness. Rejuvenation (年輕化) will be in the middle stages of research,and people will live healthily,to 85 or 100.
It's the way they think the world will live in the next century―if there's any world left!

All this antismoking stuff is tiresome. Tobacco is a critical part of our national economy,and tax income from tobacco to the state and federal government is very important. To cut to the chase,smoking is good for America. Smoking is patriotic. Everyone over the age of 21 should smoke or use tobacco.

I had a cigar with a couple buddies (companions,partners) over the Christmas weekend. And I loved it. Why would I ever want to quit such a wonderful practice? Why would anyone?
Sin and vice are good things people meet. Embrace them. Life's too short to worry about tomorrow,let alone 10〜20 years down the line.
Also,I smoked that cigar within 25 ,of an entranceway. So all you selfrighteous,antismoking jerks (fools) ... stuff it.

I think nicotine is the most highly addictive drug ever discovered. Smokers should be treated sympathetically and all health plans should pay for treatment.
#9400 ' Posted by atomicdog 88 at 12/28/05 8:26 a.m.
What if they don't want that treatment? You're still going to treat them with compassion? Maybe,let them in out of the 25' of cold to enjoy a smoke with their meal or while they're out having a good time?

Seriously,smoking is a choice,they have the right too. Most people who smoke want to. The sad truth is that we all pay the high medical costs for their poor health. But smokers do cause a high amount of state tax.
Vmalways against the socalled "sin" taxes. I think they should be repealed and replaced with a flat state income tax. I could care less about smokers―except their financial burden on my insurance premiums (保險(xiǎn)費(fèi)) .

Several weeks ago,I had a letter from Mr. Li Pengyi,President of the Foreign Language Teaching and Research Press,Beijing. He asked me to prepare some formal documents and send them to him soon.

It has been hot in London lately. The wind blows dust and leaves around. People go to work feeling tired,thinking it would be nice to have a bit of rain. Dull work in offices is even duller than usual in weather like this.
On 17 June,I reached the last part of my paperchase at the Chinese Consulate (領(lǐng)事館) . After I pushed my pile of documents through the hole in the glass screen.

I saw him write the name, "Alexander",in Chinese. He looked up,suddenly a very bright individual,no longer just a bored senior official.
"Are you the author?" he asked.
"No”, I replied. "The author was my husband,L. G. Alexander. He died. On 17th June. He died a year ago today."
He turned to his colleagues,firing off a statement in Chinese. They all paused in their work and turned to me,smiling kindly. Then the official spoke quietly but very clearly.
"We are very sorry to hear it,very sorry indeed. But you must cheer up. Mr. Alexander is very popular in China. I learned English from New Concept English. My colleagues learned English from New Concept English. Now my daughter is learning from New Concept English as well. So for us he has not died."

You will be in a new place. It may be difficult to know what to do. Here are seven tips to help you make it through the first days at a new job:
1. First impressions can last forever. Make sure you make a good one. Before your first day,find out if your new job has a dress code. If so,be sure to follow it. No matter what,always be neat and clean.
2. Get to work on time. Employers value employees who come to work right on time. Give yourself an extra 15 minutes to make sure you arrive on time.

4. Ask plenty of questions. Make sure that your supervisor has told you what is expected of you. If he or she has not told you your job duties,ask for a list. Set daily and weekly goals for yourself.
5. Do not take too long for lunch. What is the lunchhour policy at your new job? You can find out from your supervisor or your company's personnel department. For example,do people eat at their desks or does everyone take a full hour outside the workplace?

Prevention is a central issue being discussed at the sixteenth International AIDS Conference in Toronto,Canada. Twentyfour thousand delegates are at the conference which ends Friday.
Bill and Melinda Gates called for faster research to develop preventions like microbicides for women to use when they have sex. The hope is that such products could protect against infection with the virus that causes AIDS.
Melinda Gates said the way to "change this epidemic" is to put power in the hands of women. In southern Africa,for example,about sixty percent of adults living with HIV are women.
Bill Gates said women today often have no choice but to depend on men not to infect them. "A woman should never need her partner's permission to save her own life," he said as the conference opened Sunday.
The world's richest man said "stopping AIDS" is the top priority of the Bill and Melinda Gates Foundation.
On Monday,former President Bill Clinton said more people would get tested for HIV if an aggressive effort took place to fight the stigma (恥辱) .But reducing fears of social rejection is not enough. Mister Clinton said people also need a guarantee they would get medicine to suppress (抑制) the virus.
Researchers at the conference presented the results of a new study of HIV testing. It involved more than one hundred thousand people tested in California last year. Some received a quick test,with results in about twenty minutes. The others received a test that is more commonly used,the results takes two weeks.
The researchers say twentyfive percent of the people who had the longer test did not return to learn the results. But that was true of only two percent of those who had the quick test.
George Lemp of the University of California led the study. He says quick tests could be especially important in developing countries with limited transportation.
Speakers at the AIDS conference also discussed high rates of new HIV infections among black Americans. Julian Bond is chairman of the NAACP,a leading civil rights group. He said African-Americans must,in his words , " face the fact that AIDS has become a black disease."
( ) 5. In which of the following sections can you find the passage on the Internet?
A. Economics report. B. Health report.
C. Science in the news. D. American news.
( ) 6. Which of the following statements is true according to the passage?
A. Black Americans are easy to be infected by HIV.
B. Bill Clinton called on people to accept the people with HIV.
C. The couple of Gates realized that women need help most.
D. A quick HIV testing is commonly used in the current world.
( ) 7. The underlined word "epidemic" probably means .
A. a kind of virus
B. widespread occurrence of a disease
C. the situation that women depend on men
D. family structure
( ) 8. Which of the following is the best title for the passage?
A. The New Scientific Achievement at AIDS Conference
B. Prevention―the Theme of the AIDS Conference
C. The Way to Save Women and Black Americans
D. AIDS—a Black Disease
( ) 9. What can we infer from the passage?
A. Effective ways have been found to prevent the HIV infection.
B. More and more people are concerned about AIDS.
C. The first target for the Bill and Melinda Gates Foundation is to stop AIDS.
D. The best way to prevent AIDS is to have HIV testing.

Slang is one of those things that everybody can recognize and nobody can define. Not only is it hard to wrap slang in a definition,it is also hard to distinguish it from such similar things as colloquialism,provincialism (方言) ,jargon (行話) or trade talk.
Usually,slang tends to be transient. Thus parents are often laughed at by their children when this older generation uses slang which was considered to be the height of fashion in their own youth. Of course,the slang teenage children use today is very different from that of their parents. Indeed it might ever be some obscure (difficult to understand) foreign language as far as the older generation is concerned for it is totally beyond their understanding.
It is often said that a slang term stops to be slang when it is "accepted by the dictionary". This is not really the case. You will find many slang terms listed in dictionaries are still slang terms. The term stops to be slang when it drives its respectable synonym (同義詞) out of use,or when it acquires a meaning that cannot be expressed otherwise.
Such things have happened. The term "hot dog" was once a slang term,but it couldn't be considered so now. No one in America would go up to a counter and order "a sausage sandwich". Similarly "varsity", originally a slang contraction (short form of a word) of university,has acquired a special meaning which only it expresses and is no longer slang. Jazz,when it means a particular kind of music,is scarcely a slang form,since there is no more respectable word meaning that kind of music.
( ) 1. Which would be the best title for this passage?
A. Slang Terms and Other Forms of Language
B. Slang Terms and Their Meanings
C. How to Understand Slang Terms
D. Slang
( ) 2. Parents are often laughed at by their children when .
A. they use some obscure slang
B. they try to learn from their children
C. they use out-of-date slang
D. they want to follow the fashion
( ) 3. The examples in the last paragraph are intended to show .
A. when a slang word disappears
B. when a slang word is no longer slang
C. how to use slang words
D. how to understand slang words
( ) 4. The underlined word "transient" in the second paragraph probably means .
A. hard to understand B. easy to understand
C. temporary D. everlasting
