[2]Researchers in the state of Rhode Island measured the amount of the hormone(荷尔蒙) melatonin(降黑素) in people"s mouths at different times of the day. Melatonin causes people to feel sleepy.
[3]They found that melatonin levels rise later at night in teenagers than they do in children and adults. It remains at higher levels in teenagers later in the morning. They said this shows that teenagers have difficulty learning early in the morning. Yet most school systems in the United States begin high school classes at about seven o"clock.
[4]A few school districts have made some changes. In 1996, school officials in Edina, Minnesota, changed the start of classes from seven thirty to eight thirty. Two years later, the nearby city of Minneapolis did the same. Teachers there reported that students were no longer sleepy in class and were happier. Staying in school later in the day did not seem to be a problem for students who had jobs after school either.
[5]Health experts say that teenagers need between eight and nine hours of sleep a night. Students _________ are likely to be

[6]Some people, however, don"t support a later start time because they say that it would limit the time for practicing sports after school. However, the Minnesota schools found that this did not hurt school sports competitions.
[7]More American school districts are discussing the possibility of changing high school start times. Researchers and teenagers say that they cannot make the change quickly enough.

A lazy Susan may also be a part of a kitchen cabinet (橱柜). In this sense, the lazy Susan is a type of shelving unit within the cabinet that is able to turn around its axis(轴心) . One may turn the lazy Susan in order to find certain goods in storage. From the outside, a lazy Susan appears to be two cabinets that are located at a right angle (直角) to each another. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
It is believed that Thomas Jefferson invented the lazy Susan in the 18th century, though it was called “dumbwaiter” at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph (留声机). The turntable may have developed into the lazy Susan later.
Regardless of who invented it, it wasn’t until 1917 that the term “lazy Susan” was used in an advertisement for the invention. In Britain, however, the term “dumbwaiter” is still used rather than “lazy Susan”. The reason for the naming of it is still a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.

Here are some definitions of the short story. My favorite is Benet"s: “something that can be read in an hour and remembered for a lifetime”. One writer said, “The theme of a novel won"t fit into the framework of a short story; It"s like trying to squeeze a large painting done on a wall into the frame of a miniature (微型画)。 And as in a miniature painting, the details need to be sharp. ”
The short story is an example of one aspect of human nature. Often a character undergoes some event, something that offers him or her change. This is why it’s said that short stories usually “say something ”, often a small something, but sometimes delivered with such accuracy that the effect is strongly felt, even a life-moment for some readers, something similar to a religious experience or to witnessing a never-to-be-repeated scene in nature.
Ok, let’s form a definition here: A short story is an account, rarely over 10, 000 words or below 500 words-more commonly 1, 500 to 5, 000 words-a single-sitting read, but with enough time and weight to move the reader. It is narrow and focused to produce an effect through the story, most commonly through events affecting some change in an individual.
Writer Isabelle Allende once wrote: “Novels are, for me, adding up details, just work, work, work, then you"re done. Short stories are more difficult-they have to be perfect, complete in themselves. ”
小题1:The writer of the passage is probably a ______.
A.poet | B.painter | C.teacher | D.student |
A.at most 10, 000 words | B.below 500 words | C.over 5, 000words | D.around 2, 000 words |
A.experiences | B.discovers | C.discusses | D.appreciates |
A.Novels are too long for us to read. |
B.Short stories are too short for us to read. |
C.Short stories have more details than novels. |
D.Short stories are more perfect and difficult than novels. |
A.How Do You Write a Short Story? | B.What Exactly Is a Short Story? |
C.Is a Short Story Similar to Poetry? | D.Are Short Stories Perfect and Complete? |
About 300 B.C. an Indian writer described forest that were somewhat like national parks today. The killing of game beasts was carefully supervised(监视). Some animals were fully protected.Within the forest, nobody was allowed to cut timber(wood for building), burn wood for charcoal(炭), or catch animals for their furs. Animals that became dangerous to human visitors were caught or killed outside the park so that other animals would not become uneasy.
The need for wildlife protection is greater now than ever before. About a thousand species of animals are in danger of extinction, and the rate of extinction was about one species every fifty years from A.D. 1 to 1800, but now it is about one species every year. Everywhere, men are trying to solve the problem of protecting wildlife caring for the rapid growth of the world’s population.

"The hatred we hold within us is a cancer," Professor Ken Hart said, adding that holding in anger can lead to problems such as high blood pressure and heart disease.
More than 70 people have become members in Hart’s first 20-week workshop in London ─ a course he says is the first of its kind in the world.
These are people who are sick and tired of living with a memory. They realize their bitterness is a poison they think they can pour out, but they end up drinking it themselves, said Canadian-born Hart.
The students meet in groups of eight to ten for a two-hour workshop with an adviser every fortnight.
The course, ending in July, is expected to get rid of the cancer of hate in these people. "People have lots of negative attitudes towards forgiveness," he said. "People confuse forgiveness with forgetting. Forgiveness means changing from a negative attitude to a positive one."
Hart and his team have created instructions to provide the training needed.
"The main idea is to give you guidelines on how to look at various kinds of angers and how they affect you, and how to change your attitudes towards the person you are angry with," said Norman Claringbull, a senior expert on the forgiveness project.
Hart said he believes forgiveness is a skill that can be taught, as these people "want to get free of the past".
小题1:From this passage we know that ______.
A.high blood pressure and heart disease are caused by hatred |
B.high blood pressure can only be cured by psychology professors |
C.without hatred, people will have less trouble connected with blood and heart |
D.people who suffer from blood pressure and heart disease must have many enemies |
A.try your best to defeat him or her |
B.never meet him or her again |
C.persuade him or her to have a talk with you |
D.try to build up a positive attitude towards the person |
A.meet their enemies |
B.change their minds |
C.enjoy the professor’s speech |
D.learn how to quarrel with others |
A.pay much money to Hart |
B.go to the workshop every night |
C.attend a gathering twice a month |
D.pour out everything stored in your mind |
