food for other animals or plants. However, animals can"t get food from many of the things that we "give"
the Earth. Animals and plants can"t eat metal, plastic and glass. These things will stay in the ground for many,
many, many years.

animal makes food for many more animals. If we put rub- bish and chemicals in the water,the plank- ton

reading is so difficult that it almost seems like a foreign language. In a way, it is the language of science.
You should not expect to be able to read a difficult science passage the same way you read an interesting story;
you should not expect to read it easily and all at once. Instead, you may have to read it several times through,
catching on the meaning of difficult words,going back over difficult sentences, and finally putting the whole
thing together. Do not be discouraged if the whole passage doesn"t make sense to you at first. You need to
pick it apart patiently until you can understand it.
These are the steps to follow when you are reading something difficult;
☆1. Start to read normally until you run into a sentence that doesn"t make sense to you.
☆2. When a sentence doesn"t make sense,go back and read it again more slowly.
☆3. Look for any words you don"t know in the sentence. Try to understand their meanings using word parts
and context clues (上下文线索) . If necessary, look them up in the dictionary.
☆4. Look at the next few sentences to see if they explain more about the sentence you are working on. Do
not read very much farther ahead until you understand what is being said.
☆5. Finally, read the sentence again. Try to put it into simpler words.
☆6. Read through the passage once. Try to understand all the hard parts well. Then read the whole passage
once more at a usual speed. This helps you to put all ideas together.
The steps sound a lot harder than they are. It is really just the normal way good readers understand
anything that is difricult to read. After you have done the best you can this way,you should always feel free
to ask for help from your teacher,if you have one.

person was born. From China comes the belief that the year of birth influences one"s personality. In the past
century, a new belief has arisen: the idea that personality is related to one"s ABO blood type. People with blood
type A, for example, are considered more likely to be serious, hard-working, and quiet, while people with blood
type O are likely to be popular and outgoing, yet often unable to finish what they start. Though this belief
continues to be strong, some people question whether it is true.
The blood-type personality theory (理论) started in Japan in 1927 when Fu- rukawa Takeji noticed
personality similarities and differences among his workers. The idea soon went out of fashion, but was
brought back by a Japanese television host named Toshitaka Nomi in the 1970s. The belief is still strong in
Japan and is increas- ingly popular in neighboring countries. Some young Koreans have taken to the theory.
A recent study showed 76 percent of Koreans aged between 13 and 64 believing in the blood-type personality
connection. Though most Asians might believe in the blood-type theory, for many it seems harmless and not
something to be taken too seriously.
There is also the possibility that people are influenced to change their personality to match the expected
stereotypes (思维定式). A survey of studies made in Japan over a 10-year period found that while in the 1970s
there was no relationship between blood types and personality, later studies in the 1980s found that the
relationship increased a little. Researchers concluded that as the belief in the stereotypes increases, people
may be changing their personality to follow the blood-type theory.
Is the belief true? The scientists in Asia largely dismiss the belief as a modem day superstition (迷信).
Most studies have failed to find any strong connection between blood and personality. Generally, scientists
warn against making predictions or important decisions based on this questionable theory.
B. the relationship between the two blood types
C. the influence of blood types on one"s behaviour
D. the connection between personality and blood types
B. It was brought to them.
C. They liked and accepted it:
D. They stole the idea from others.
B. The blood-type theory began in Japan in the 1970s.
C. The blood-type personality theory is about blood types.
D. People don"t change their personality to match the theory.
B. Is the personality changeable?
C. Is it in your blood?
D. Is it in your mind?
over time, a study suggests.
The study included 332 African-American and 775 Hispanic-American (西班牙裔美国人) men and women
aged 18 to 81. The researchers measured their abdominal(腹部的) fat, at the start of the study and again five
years later.
Among the people younger than 40 in the research, the study found, those who said they slept for five hours or less each night gained more fat than those who averaged six or seven hours of sleep. Those who slept eight
hours or more in bed each night also showed a bigger fat gain-but it was not as much as that seen in "short
sleepers " .
The findings, according to the lead researcher Dr Kristen, support the belief that sleep habits affect weight,
and health in general. " Sleep is an important part of your overall health-not just in whether you"re tired during
the day," he said.
As for why sleep time might affect abdominal-fat gain, there are several facts:
People who get too little sleep may be too tired during the day to exercise, while those who spend a lot of
time in bed may spend less time being active, comparing to people who sleep fewer hours. Research also
suggests that sleep loss changes people"s appetite-regulating hormones (胃口调节荷尔蒙)-which could, in
theory, make them overeat.
What"s more, depression, which is a feeling of sadness that makes people think there is no hope for the
future, could also be a reason. He also noted that it often affects people"s sleep and has been linked to weight
gain.
B. People who sleep more than 8 hours every day
C. Younger adults who are from Africa or America
D. People who sleep about six or seven hours a day
B. sleep habits
C. too little sleep
D. too much sleep
B. The less we sleep every day, the less fat we will get.
C. Those who are in sadness could easily get a bigger fat gain.
D. The African and Hispanic adults easily get a greater weight gain.
