More than one in eight U. S. adults finds it hard to stay away from the Internet for several days at a time and about one in eleven tries to hide his or her online habit, according to a study showed on Tuesday.
The study by researchers from the Stanford University School of Medicine in California found one in eight adults admitted they needed to spend less time online, saying this showed "problematic Interact use" is present in a sizable portion (部分)of the population.
The study involved a nationwide telephone survey of 2,581 respondents in the spring and summer of 2004 with researchers then examining the data and preparing the report which appears in the October issue of CNS Spectrums.
The survey found that 68.9 percent of respondents were regular Internet users and 13.7 percent of the users found it hard to stay offline for several days at a time.
It found 12.4 percent often stayed online longer than intended, more than 12 percent said they saw a need to cut back on their Internet use, and 8.7 percent tried to conceal (隐瞒) "non-essential "Internet use from family, friends and employers.
A smaller number, 8.2 percent, said they use the Internet to escape problems or a bad mood, while 5.9 percent felt their relationships suffered because of too much Internet use.
One report published earlier this year said that 5 percent to 10 percent of the population likely will experience Internet addiction (上瘾).
It said signs include a disregard for health or appearance, lack of sleep and reducing physical activities and social communications with others, as well as dry eyes and juries of hands and fingers.
【小题1】From Paragraph 2, it tells us _______.

More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1966, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition it was all good news too. This nice tasting pineapple contained four times more vitamin C than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.
【小题1】We learn from the text that the new type of pineapple is __________.

A．green outside and sweet inside	B． good-looking outside and soft inside
C．yellowy-gold outside and hard inside	D．a little soft outside and sweet inside

More than three years after moving from Australia to this remote part of England, we are still learning how things are done here.

Not too long after we arrived and unpacked, we were invited for “a drink on Sunday morning” by a retired couple nearby. We got there about noon, to find the living-room crowded — lots of chat and discussions, and in all a very jolly occasion.

Trouble was, there was no food — no self-respecting Australian would regard a tray of crisps as food. In Sydney, when you are invited for a drink any time after midday on a Sunday, you know you will be fed as well as watered and you plan accordingly. Meaning the hardworked little woman makes no plans to cook lunch because you are eating out.

By one-fifteen my stomach was sending up “please explain” to me. Even the crisps had gone. There was nothing we could do except wait, and wonder if the hostess was going to perform some magic and feed us fashionably late. Then, as quickly as if word had spread that there was free beer at the local pub, the room emptied. By one-forty-five there were only a few guests left, so we decided to go home. Tinned soup for lunch that day because the little woman was not really interested in real cooking for us.

A few weeks ago we were invited out for “supper” and the hostess suggested 8:15. Ah, we thought greedily, “this is going to be the real thing.”

We dressed with some care — I putting on a dark suit — and arrived on time. My wife looked pretty good, I thought — a little black dress and so on. But when we walked in I had a terrible feeling we had got the night wrong because the hostess was dressed in a daytime kind of way and the husband was in jeans and an open-neck shirt. But no, we were greeted and shown into the sitting-room.

After a drink I looked around and saw that this was indeed a superior cottage because it had a (more or less) separate dining-room. But there were no signs of a table-setting. Not again! I thought. Were we meant to eat before we came? I decided that in future my wife and I would always carry a chocolate bar. About 9:28 our hostess went out of the room, saying something about food. Ten minutes later she returned and asked us to follow. We were led out to the kitchen. There on the table were country style plates and a huge bowl of soup, rough bread and all the makings of a simple meal. And that is what it was. In other words we had not read the signals right when we were invited for “supper”. If they want you to come to dinner, they say so, and you know that means dark suits and so on. If they mean supper, they say it, and you get fed in the kitchen.
