Several days before, I was out with my friends at a local fast food restaurant. The food we ate was good but we had fun together. Before we left for the restaurant, we found that it also sold ice cream. We got exciting because we hadn’t eaten ice cream for a long time. One of my friend decided to buy all of us ice cream and in the restaurant, they all screamed (尖叫) with joy! Then the man came in with his son, who wanted to buy ice cream either. In the end, he decides to pay for our ice cream. We moved by such an act of kindness on a hot day.

   Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.

New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It’s almost like leaving a footprint on wet cement (水泥)----it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

Internet use appears to cause a decline in psychological well-being（安康）, according to research at Carnegie Mellon University.
Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who logged on less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling.
Researchers are puzzling over the results, which were completely contrary to their expectations. They expected that the net would prove socially healthier than television, since the Net allows users to choose their information and to communicate with others.
The fact that Internet use reduces time available for family and friends may account for the drop in well-being, researchers suggested. Faceless, bodiless “virtual”（虚拟的）communication may be less psychologically satisfying than actual conversation, and the relationship formed through it may be shallower. Another possibility is that exposure to the wider world via the Net makes users less satisfied with their lives.
“But it’s important to remember this is not about the technology  per se; it’s about how it is used,” says psychologist Christine Riley of Intel, one of the study’s sponsors. “It really points to the need for considering social effects in terms of how you design applications and services for technology.”
【小题1】The best title for this passage would be ________.

A．Internet may Cause Depression

B．The Dark Side of Internet

C．How to Use Technology Properly

D．The Importance of Psychological Well-being

【小题2】Internet use may cause a decline in psychological well-being because ________.

A．people who were already feeling bad spend more time on the Internet

B．Internet users thought the world was wider than it really was

C．people were too eager to turn the “virtual” communication into reality

D．people have less time for actual communication with their family and friends

【小题3】What does the underlined Latin word “per se” (in Para. 5) mean?

A．probably	B．absolutely
C．oneself	D．itself

【小题4】What’s the tone of the passage?

A．Optimistic.	B．Critical.
C．Objective.	D．Pessimistic.

Weeks ago, one of my classmate brought in a very large suitcase and placed it under his bed. Though we lived on the ground floor, his suitcase soon got wet. He took it out and after drying it, he put it on his desk. My desk happened to being opposite his. It was such the large suitcase that it not only occupied the whole of his desk but also half of my as well. I was so annoyed that I pushed it angry forward. I pushed a bit of too hard and the suitcase fell his desk. Seeing this, he flies into a temper and shouted at me. Then we had a bitter quarrel. Some days later, I regretted having done that. Lived in a room, we should learn to get on well with one another.
