The definition of the standard kilogram is almost entirely wrong. Getting that definition right is a challenge that has tried the patience and intelligence of scientists for decades.

Scientists use just seven basic units to define all the other quantities we use - quantities such as speed or electric power. All of those basic units except the kilogram are themselves defined according to natural properties(属性)that are beyond human control.

For example, the standard second (time) is defined as a specific number of vibration(振动)of a type of radiation sent out by atoms of a special metal. The standard metre (length), in turn, is defined as the length of the path light travels under certain conditions.

Not so the kilogram. This orphan of the basic unit family is simply the mass of a small platinum-iridium alloy cylinder(铂-铱合金筒)locked away in a container maintained by the International Bureau of Weights & Measures in Sevres, France, near Paris. Official bodies around the world have copies of the cylinder.

Embarrassingly, the last time the copies were brought to Sevres for a checkup in the 1980s, officials found that some copies had gained about 20 parts per billion in weight compared to the master cylinder since the previous checkup in the 1940s. This implies that the master cylinder itself may be an inconstant standard.

Several efforts in several different countries are under way to redefine the kilogram according to basic physical quantities such as counting the actual number of atoms of a specific substance in a kilogram or the electromagnetic(电磁的)force that balances a kilogram mass against gravity. A project of the latter type at the laboratories in Gaithersburg, Md., hopes eventually to define mass by means of electrical units.

So far, none of these redefinition projects has borne fruit. They require the very precision of measurement and control of experimental conditions. The slightest influence - even a tiny change in weather - can ruin results. You’ve got to hand it to scientists who are willing to devote many years to such painstaking - but extremely important - research.

86. Compared with other basic units, the kilogram is ______.

    A. as accurate as other basic units

    B. not defined according to natural properties

    C. not universally accepted in the world

    D. defined in the same way as other basic units

87. The author introduced the examination of copies of a platinum-iridium alloy cylinder in the 1980s to indicate that ______.

    A. the causes of weight changes had been found

    B. such kind of checks had been carried out regularly

    C. the changes in weight challenged the definition of the kilogram

    D. the consequences of such changes were great in research

88. According to the passage, to define the weight of mass by means of electrical units ______.

    A. is the only way to redefine the kilogram scientifically

    B. has been accepted as the only possible redefinition project

    C. is not as simple as people understand

    D. has been considered by some scientists as a better approach

89. Which of the following CANNOT be concluded from the passage?

    A. Scientists will achieve success in redefining the kilogram in the near future

    B. Some scientists are trying to redefine the kilogram according to basic physical quantities.

    C. The redefining of the standard kilogram is quite complicated and can be affected by a      number of factors.

    D. A number of experiments are being carried out to redefine the kilogram.

    Every once in a while you will read some article about a so-called scholar discovering material that is supposed to prove that William Shakespeare did not really write the works attributed to him.

    Many alternative authors have been suggested-Christopher Marlow and Francis Bacon. One supporter of Bacons as author of Shakespeare’s plays actually looked for words like “fat and lard” and calculated how their places in the texts of the plays proved that Bacon authored them.

    Any schoolboy can see the wrong idea of such an argument and yet many adult readers of newspaper articles, written by men who have never done any research on Shakespeare, are taken in by the arguments proposed against Shakespeare’s authorship.

    It is true that we have no manuscripts of the plays as they came from Shakespeare’s hand. After all, he wrote the plays to be acted and the actors used the author’s manuscripts. However, almost half the plays appeared in print under the author’s name during his lifetime-which ended in 1616. A few years later, in 1623, two of Shakespeare’s actor friends published a great book with thirty-six plays and put Shakespeare’s name on the title page. They even got Ben Johnson, Shakespeare’s great rival play writer, to write a poetic introduction for the book.

    There are other arguments I might present to prove Shakespeare’s authorship. My own argument is simply this, if Shakespeare did not write the plays attributed to him, it was someone else by the same name.

82. The first paragraph tells us that some so-called scholars ____.

  1. have already proved that Shakespeare’s works were not his own
  2. have proved that Shakespeare’s works were his own.
  3. Try to prove that Shakespeare’s works were not his own
  4. Try very hard to prove that Shakespeare’s works were worthless

83. Some people suggested that certain writers other than Shakespeare himself were the authors of his plays. One of them did so by____.

  1. examine the whole text of Shakespeare’s works
  2. discovering words such as “fat” and “lard” in Bacon’s plays
  3. checking up every word in Shakespeare’s works
  4. comparing the use of words in Shakespeare’s works with others’

84. The author states in the third paragraph that it is amazing to find so many people ____.

  1. are fooled by schoolboys
  2. have never done any research on Shakespeare
  3. are easily persuaded to doubt Shakespeare’s authorship
  4. have always been interested in newspaper articles about arguments proposed against Shakespeare’s authorship

85. One difficulty in proving Shakespeare’s authorship is that ____.

  1. the plays were written so long ago
  2. the plays appeared only in print in 1616
  3. the actors and publishers during his lifetime had changed the plays
  4. the author’s manuscripts of the plays are no longer available

Have you seen these people?

 

 

 

 

 
Jane Peters, aged 21
   Jane was walking to college with a friend. The fried went back to her flat because she had forgotten something and Jane walked on alone. She never arrived at college and she has not been seen for the last five years. The video recording of some shops near the college shows Jane talking to a man on the afternoon that she disappeared. None of her friends can identify the man.
   Jane is of slim build. When she was last seen, she was wearing a blue jacket and carrying a school bag with her books in it.
 
Arthur Sugden, aged 61
   Arthur went to get a newspaper at the local corner shop and never came back. He has been missing for seven years. His wife Pru says he had problems at work but for him to just walk out like that was “com­pletely out of charac­ter”. It is thought that Mr Sudgen had money worries and police believe he had been gambling.
   Mr Sugden is of medium build and has thinning brown hair. When last seen he was wearing a blue jacket, grey trousers and a white shirt with a red tie.
 
Richard (Dickie) Gallagher, aged 5
   Last summer, Dickie Gallagher was playing on the beach on the family holiday in Corfu when he suddenly disappeared. The police searched the beach and interviewed people at nearby hotels. Coastguards searched the sea for two days after he disappeared. They believed that if Dickie had drowned the body would have been found by now. His elder brother Leon, aged 12, was looking after Dickie while his parents went back to their hotel for a sleep. Dickie climbed over a wall and when Leon went to look for him he was gone. No tourists on the beach remember seeing him on his own. His father has given up his job to return to Corfu. The family are preparing to sell their house to raise money to help in the search for Dickie.

While we haven’t discovered the “fountain of youth”, there are some simple and highly effective ways to achieve these goals. Many people  that bodily decline(衰老)comes with advanced age, but this doesn’t have to be . Research shows that you can enjoy years of active  life with few of the traditional  of aging(变老).

Normally the DNA in our cells determines when and how our cells age and die. The concept of programmed cell death, known as apoptosis, is a(n)  of intense scientific study. Researchers are busy looking for ways to  aging. To a large extent, the programmed time of cell death is out of our immediate control. But premature(过早)aging is  our control.

Most physical signs of aging, such as wrinkles and poor vision, are brought on prematurely by a combination of  factors and poor lifestyle habits. Some of these factors include pollution, over-exposure to sunlight, too much alcohol consumption, smoking, inactivity, a lack of exercise and poor nutrition. All lead to cell damage, which  the aging process and can lead to illness and disease. , a healthy lifestyle will enable us to enjoy an active body, a clear mind and a lively spirit.
