In 1977,a dead author of detective stories saved the life of a 19-month-old baby in a most unusual way.The author was Agatha Christie,one of the most successful writers of detective stories in the world.

In June 1977,a baby girl became seriously ill in Qatar,near Saudi Arabia.Doctors were unable to  1    the cause of her illness,so she  2  to London and admitted to Hammersmith Hospital,where specialist help was  3  .She was then only half-conscious(半昏迷)and on the“Dangerously Ill”list.A team of doctors hurried to  4    the baby only to discover that they,,were puzzled by the very unusual symptoms.While they were discussing the baby’s case,a nurse asked to  6   to them.

    “Excuse me,”said Nurse Marsha Maitland,“   7   I think the baby is  8  from thallium poisoning.”

    “  9  makes you think that?”Dr.Brown asked.“Thallium poisoning is extremely  10  .”

    “A few days ago,I was reading a novel called A Pale Horse    11   Agatha Christie,”Nurse Maitland explained.“In the book,somebody uses thallium poison,and  12   the symptoms are   13  .They are exactly the same as the baby’s.”

    “You’re every observant and you may be right,”another doctor said.“We’ll  14   some tests and find out  15  it’s thallium or not.”

      The  16  showed that the baby had  17  been poisoned by thallium,a rare metal used in making optical(光学的)glass.   18  they knew the cause of illness, the doctors were able to give the correct treatment.The baby soon 19    and was sent back to Qatar.1nquiries(调查)showed that the poison  20 from an insecticide(杀虫剂)used in Qatar.

Night after night,she came to tuck me in,even long after my childhood years.Following her longstanding custom,she’d lean down and push my long hair out of the way,then kiss my fore-head.

I don’t remember when it first started annoying me—her hands pushing my hair that way.But it did annoy me,for they felt work-worn and mush against my young skin.Finally,one night,I shouted out at her,“Don’t do that anymore--your hands.are too rough!” She didn’t say anything in reply.But never again did my mother close out my day with that familiar expression of her love.

Time after time,with the passing years,my thoughts returned to that night.By then I missed my mother’s hands, missed her goodnight kiss on my forehead.Sometimes the incident seemed very close,sometimes far away.But always it lurked(潜藏),in the back of my mind.

Well,the years have passed,and I’m not a little girl anymore.Mom is in her mid—seven—ties, and those hands I once thought to be so rough are still doing things for me and my family.She’s been our doctor,reaching into a medicine cabinet(医药箱)for the remedy(药物)to calm a young girl’s stomach or soothe(安慰)the boy’s scraped(擦伤的)knee.She cooks the best fried chicken in the world…gets stains out of blue jeans, like I never could…

Now, my own children are grown and gone.Mom no longer has Dad,and on special occasions.I find myself drawn next door to spend the night with her.So it was late on Thanksgiving Eve, as I slept in the bedroom of my youth, a familiar hand hesitantly run across my face to brush the hair from my forehead.Then a kissever so gentlytouched my brow(额头)

In my memory,for the thousandth time,I recalled the night my young voice complained,"Don’t do that anymore--your hands are too rough!" Catching Mom’s hand in hand,I blurted (冲口说出)out how sorry I was for that night.I thought she’d remember ,as I did.But Mom didn’t know what I was talking about.She had forgotten--and forgiven—long ago.

That night, I fell asleep with a new appreciation for my gentle mother and her caring hands. And the guilt that I had carried around for so long was nowhere to be found.

Vienna—In spite of Iraq’s decision to stop oil deliveries,the 11-nation Organization of Petroleum Exporting Countries(OPEC)will not increase production to make up the shortfall, ministers decided Tuesday in Vienna.

    The 11 oil ministers decided to meet again on July 3 to discuss the effects of the Iraq temporary stop.The organization’s president,Charkid Kheria of Algeria,said after the meeting that stocks were high and prices were stable,so quota(配额)increases were not necessary.

    The E.U.Commission has expressed concern about Iraq’s output stop.A speaker said OPEC had to take all possible measures to keep or lower the oil price.

    Saudi Arabia’s Oil Minister Ali Al-Nuaimi had earlier said there would not be any shortfall of oil in the market.

    The organization had already taken steps to fill the gap,he said.OPEC Secretary General Ali Rodriguez added that the period of Iraq’s output stop was not known,so other exporters were not going to lift quotas yet.If the market was destabilized(使……动摇),a suitable response could be made.

    Iraq on Monday s topped shipments of crude oil to protest against the U.N.Security Council’s decision to extend the oil-for-food program by only a month,instead of the normal six-month renewal.Just before the Vienna meeting,oil prices had gone up,with a barrel of OPEC crude oil selling for 27.05 dollars,up from 26.8 1 dollars last Friday. North Sea oil was at 29.26 dollars Monday evening.

    OPEC wants the oil price to stay within a margin of 22 to 28 dollars and achieved that with cuts in January and March that reduced 2.5 million barrels per day off quotas.

How would you like to sleep with one half your brain asleep and the other half awake? Dolphins sleep this way. Recently, scientists at Indiana State University have discovered that ducks sleep this way too. They found that ducks sleep half awake so they can rest and watch for danger at the same time.

After putting their ducks in a row and videotaping them, some researchers found ducks on the end of each row spent more time asleep with one eye open, apparently looking for predators.

“The more the ducks felt threatened ,the more they slept with one eye open,” said lead author Niels C.Rattenborg, a graduate student at Indiana State University, Terre Haute.” the unique aspect is not that they do it, but that they control it. When they sleep at the edge of a group, they tend to realize greater danger, so they spend more time sleeping with one half of their brain.” Ducks with one eye open were still awake enough to detect predators, said the authors of the study, which appears today in the Journal Nature.

The researchers studied four groups of four ducks held in plastic boxes, which were arranged in a row. Ducks on the end were found to sleep with one eye open 31.8 per cent of the time, compared to 12.4 percent of the time for ducks in the central position.

Also, ducks in the central position did not open one eye more than the others, while ducks on each end kept the eye facing away from the group open 86.2 per cent of the time. Brain wave readings of the ducks showed that the half of the brain receiving signals from the closed eye indicated that half of the brain was sleeping. Signals from the half of the brain receiving signals from the open eye showed a state between fully awake and asleep.

       D.A video tape recorder was the only electronic device used in the experiment.

Many new students find it hard to do all the study that has to be done; they find themselves putting off reading assignment, jumping from subject to another and rarely being quite certain what they are trying to do during a particular study session. The best way to overcome these difficulties and to start studying efficiently is to plan your time and organize your work. Let us suppose that you have 15 hours per week of classes and that you decide to allow yourself a 40-hour working week (a reasonable figure, leaving you 70 waking hours for other activities).

You now have to decide how to divide the remaining 25 hours of private study. Naturally the decisions you make will change from week to week according to what essays have to be written and what reading has to be done. Many people find it helpful to draw up each week a seven-day timetable showing the occasions on which they will be working privately and the particular subjects that will be studying on each occasion. By checking such a plan at times during the week, you can see what you have done and what you have still to do: the whole plan becomes more manageable. There are a number of places where you can study—college library, public library, home, empty classrooms, on bus or train—and each has several obvious advantages and disadvantages. The college library is least busy in the evening, on Wednesday afternoon, and all day Friday and Saturday.

When you are deciding where to study, keep the following suggestions in mind:

1.Try to study always in the same place. After a while the familiar surroundings will help you to switch into the right frame of mind as soon as you sit down.

2.Find somewhere with as few distractions as possible.

3.Make sure that your study place has a good light and is warm (but not too warm ) and well aired.

1.Many new students find it hard         .

       A.to make a good start                            B.to study efficiently

       C.to delay their reading                           D.to jump from subject to subject

2.What’s the main idea of this passage?

       A.Plan your time and organize your work  B.Overcome your difficulties.

       C.Be certain what you can do.                  D.Find a quiet place for study.

3.A student’s organization of his work will need to change according to         .

       A.how many hours he is awake              B.how many subjects are required

       C.how many lectures he misses               D.what he has to write and read that week

4.A student is advised to make a weekly plan and to check it from time to time in order to  __________.

       A.see whether he has calculated it properly

       B.see what day of the week is

       C.see what work still needs doing

       D.see how he feels at the whole week

TUVALU, a tiny country in the Pacific Ocean, has asked for help as it will be swallowed up by the sea.

       Storms and huge waves are a constant threat and none of Tuvalu’s nine little islands is more than five meters above sea level. Salt water is already entering the country’s drinking water supply, as well as damaging plants that produce fruit and vegetable. Without urgent help, the country’s days are numbered.

       But Tuvalu is not the first place to face sinking into the sea. Venice, a historic city in Italy best known for its canals, has sunk about 24cm over the past 100 years. Experts say that it will have sunk another 20-50cm by 2050.A century ago, St. Mark’s Square, the lowest point city, flooded about nine times a year. Nowadays, it happens more than 100 times. While Venice is slowly sinking into the mud on which it stands, global warming causes Tuvalu’s rising sea level.

       The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it rise by extra 1-3 degrees over the next 100 years.

       Warmer weather makes glaciers (冰川) melt, and adds more water to the ocean. The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen about 10-25 cm in the last 100 years.

       The main cause of global warming is human pollution. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the atmosphere, such as CO2This adds to the power of the greenhouse effect, making the planet even warmer.

         Many scientists believe that, if the warming is not stopped, there will be huge climate changes. The sea level could rise by one meter this century.

       Should this come true, the sea will swallow up millions of homes and the world will be flooded with “climate refugees” looking for somewhere to live.
