In this age of Internet chat，videogames and reality television，there is no shortage of mindless activities to keep a child occupied．Yet，despite the competition，my 8-year-old daughter Rebecca wants to spend her leisure time writing short stories．She wants to enter one of her stories into a writing contest，a competition she won last year．

As a writer I know about winning contests，and about losing them．I know what it is like to work hard on a story only to receive a rejection slip from the publisher．I also know the pressure of trying to live up to a reputation created by previous victories．What if she doesn.t win the contest again？That’s the strange thing about being a parent．So many of our own past scars and dashed hopes can surface．

A revelation（启示）came last week when l asked her，”Don’t you want to win again？” “No,” she replied，“I just want to tell the story of an angel（天使）going to first grade．”

I had just spent weeks correcting her stories as she spontaneously（自发地）told them．Telling myself that l was merely an experienced writer guiding the young writer across the hall. I offered suggestions for characters，conflicts and endings for her tales．The story about a fearful angel starting first grade was quickly“guided”by me into the tale of a little girl with a wild imagination taking her first music lesson．I had turned her contest into my contest without even realizing it．

Staying back and giving kids space to grow is not as easy as it looks．Because I know very little about farm animals who use tools or angels who go to first grade，I had to accept the fact that I was co-opting（借用）my daughter’s experience．

While stepping back was difficult for me，it was certainly a good first step that l will quickly follow with more steps，putting myself far enough away to give her room but close enough to help if asked．All the while I will be reminding myself that children need room to experiment，grow and find their own voices．

What did the author say about her own writing experience？

A．Most of her stories had been rejected by publishers．

B．She did not quite live up to her reputation as a writer．

C．Her way to success was full of pains and frustrations．

D．She was constantly under pressure of writing more．

Why did Rebecca want to enter this year’s writing contest？

A．She wanted to share her stories with readers．

B．She was sure of winning with her mother’s help．

C．She believed she possessed real talent for writing．

D．She had won a prize in the previous contest．

The author took great pains to refine her daughter’s stories because ．

A．she was afraid Rebecca’s imagination might run wild while writing

B．she did not want to disappoint Rebecca who needed her help so much

C．she believed she had the knowledge and experience to offer guidance

D．she wanted to help Rebecca realize her dreams of becoming a writer

What’s the author’s advice for parents？

A．Parents should keep an eye on the activities their kids engage in．

B．Children should be allowed freedom to grow through experience．

C．A writing career，though attractive，is not for every child to pursue．

D．Children should be given every chance to voice their opinions．

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 accuracy 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.

Compared with other basic units, the kilogram is ____.

A. as accurate as other basic units

B. not universally accepted in the world

C. not defined according to natural properties

D. defined in the same way as other basic units

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

A. is the only way to redefine the kilogram scientifically

B. has been accepted as the only possible redefinition project

C. is not as complicated as people understand

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

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.
