PALO ALTO, California----"Switching off the television may help prevent children from getting fatter---- even if they do not change their diet or increase the amount they exercise," US researchers said last week.
　　A study of 192 third and fourth graders, generally aged eight and nine, found that children who cut the number of hours spent watching television gained nearly two pounds(0.9kg) less over a one-year period than those who did not change their television diet.
　　"The findings are important because they show that weight loss can only be the result of a reduction in television viewing and not any other activity," said Thomas Robinson, a pediatrician(儿科专家) at Stanford University.
　　"American children spend an average of more than four hours per day watching television and videos or playing video games, and rates of childhood being very fat have doubled over the past 20 years," Robinson said.
　　In the study, presented this week to the Pediatric Academic Societies‘ annual meeting in San Francisco, the researchers persuaded about 100 of the students to reduce their television viewing by one-quarter to one-third.
　　Children watching fewer hours of television showed a significantly smaller increase in waist size and had less body fat than other students who continued their normal television viewing, even though neither group ate a special diet or took part in any extra exercise.
　　"One explanation for the weight loss could be the children unstuck to the television may simply have been moving around more and burning off calories," Robinson said.
　　"Another reason might be due to eating fewer meals in front of the television. Some studies have suggested that eating in front of the TV encourages people to eat more," Robinson said.
【小题1】The author tries to tell us in the first two paragraphs that ________.

Some spiders hunt on the ground, others build webs to trap their food, but the grass water spider catches its prey by running along the surface of the water.

This special water spider lives on the grassy banks of streams where mosquitoes, damsel flies and other insects come to feed and breed.

Although it is one of the largest spiders in New Zealand, it has an unusual ability. It doesn’t disturb the water as it waits for its meal, and there is barely a ripple(波纹) when it skims(掠过) across the surface at lightning speed to catch its prey.

Grass water spiders deal swiftly with larger insects like damsel flies by pulling their heads under the water and holding them there until they drown.

After a meal, the grass water spider spends up to half an hour grooming(修饰) itself. It wipes its eight eyes, brushes its antennae(触角), and takes special care to clean the hairs on its body.

It is the hairs that trap tiny bubbles(泡沫) of air so that the spider can run down a blade(叶片) of grass and stay underwater for up to an hour when it is frightened. The hairs also keep the spider dry, even underwater.

It is only when the female spider is caring for the young that she does not hunt on the water. After mating, she produces a large egg sac(囊), which she carries around for five weeks. Once the eggs start to hatch, she attaches the sac to some blades of grass or a thistle. She then tears the sac open and releases the tiny spiders into the nursery web.

1. How does the grass water spider kill its prey?

A. in a web     B. by drowning      C. by poisoning     D. with its antennae

2. the writer describes the special spider as “special” because _______.

A. it walks on water                    B. it has eight eyes

A. feeds grass and thistles to its young.　　　　

B. lives on blades of grass under the water

C. lives in the grass on the banks of streams　　

D. eats a meal once every five weeks

4. The purpose of the passage is to _______.

A. convince readers that spiders are dangerous　　

B. indicate that the grass water spider is endangered

C. list all of the spiders that can be found in New Zealand

D. describe the characteristics of the grass water spider

A Swedish man was dug out alive after being snowed in his car on a forest track for two months with no food, police and local media reported on Saturday.

The 45-year-old from southern Sweden was found on Friday, February17, too weak to say more than a few words.

He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside.

The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19.

“Just incredible that he’s alive considering that he had no food, but also since it’s been really cold for some time after Christmas.” a rescue team member told regional daily Vasterbottens- Kuriren, which broke the news.

Ebbe Nyberg, duty officer at the Umea police, said police saw no reason to doubt that the man had been stuck in the car for a very long time.

“We would not make up something like this. The rescue services were on site too and saw the same as us.” he told Vasterbottens-Kuriren.

Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.

Doctors at the hospital said humans would normally be able to survive for about four weeks without food. Besides eating snow, the man probably survived by going into a dormant-like(休眠似的) state, physician Stefan Branth told Vasterbottens-Kuriren.

“A bit like a bear that hibernates. Humans can do that.” he said. “He probably had a body temperature of around 31 degrees which the body adjusted to. Due to the low temperature, not much energy was used up.”

“Why the man ended up under the snow in the forest remains unknown,” police said.

1.Who found the Swedish man in the snow?

A．Snowmobilers      B．The police         C．A rescue team      D．Local people

3.The reason why the man could survive was most probably that 　　　　.

A．he was only forty-five year old             B．he did not use any energy

C．he slept in the sleeping bag                D．he was in a dormant-like state

4.Which is the correct order of the following events?

a．The Swedish man was stuck in the snow.     b．He was sent to Umea University Hospital.

c．He was found by snowmobilers.            d．He was recovering after treatment.

e．He stayed in his car for nearly two months.   f．He was dug out by people.

A．e, a, c, d, f, b       B．a, e, c, f, b, d        C．a, f, c, e, b, d       D．e, c, f, a, d, b
