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 (基因) 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.

Far from the traditional image of a culture of aggressive masculinity (阳刚) in which students either sink or swim, the absence of girls gives boys the chance to develop without pressure to conform (符合) to a stereotype, a US study says. Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to conform to the “boy code” of hiding their emotions to be a “real man”.

The findings of the study go against received wisdom that boys do better when taught alongside girls.

Tony Little, headmaster of Eton, warned that boys were being faded by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls. The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills.

But in single-sex schools teachers can tailor lessons to boys’ learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study’s author, Abigail James, of the University of Virginia.

Teachers could encourage boys to enjoy reading and writing with specifically “boy-focused” approaches such as themes and characters that appeal to them. Because boys generally have more acute vision, learn best through touch, and are physically more active, they need to be given “hands-on” lessons where they are allowed to walk around. “Boys in mixed schools view classical music as feminine (女性的) and prefer the modern style in which violence and sexism are major themes,” James wrote.

Single-sex education also made it less likely that boys would feel they had to conform to a stereotype that men should be “masterful and in charge” in relationships. “In mixed schools boys feel forced to act like men before they understand themselves well enough to know what that means,” the study reported.

1.What does Tony Little say about the British education system?

A. It makes girls less emotional than boys.

B. It fails more boys than girls academically.

C. It fails to give boys the attention they need.

D. It places more pressure on boys than on girls.

2.According to Abigail James, boys perform better in single-sex schools because ________.

A. boys can choose to learn whatever they are interested in

B. boys focus more on their lessons without being disturbed

C. teaching quality is relatively higher than in mixed schools

D. teaching can be designed to suit the characteristics of boys

3.Which of the following is NOT characteristic of boys?

A. Boys have sharper vision. B. Boys enjoy being in charge.

C. Boys like “hands-on” lessons. D. Boys prefer physical activities.

4.What is mainly discussed in the passage?

A. Problems boys may have in mixed schools.

B. Boys’ physical and mental growth in school.

C. Advantages of single-sex education for boys.

D. Boys’ disadvantages over girls in mixed schools.

There are two types of people in this world: those who regularly wash their office coffee cup. And those who only take it off their desk to cover up the coffee mark at the bottom with a fresh pour, driving away their shame with the reasoning that the heat must kill the bacteria or spine thing.

Depending on which type of person you are, this will be either mildly annoying or more-than-mildly exciting. As Heidi Mitchell wrote in a recent Wall Street Journal column, it’s fine to never wash your cup, as long as you’re not sharing it with anybody else.

There are two warnings to that statement, infectious-disease expert Jeffrey Strake, a professor at Baylor College of Medicine, told Mitchell; One, it only applies if you’re not sharing the cup with anybody else. And two , if you leave cream or sugar in your cup over the weekend, that can certainly cause mold(霉) to grow – in which case, wash it out.

Otherwise, though, there’s not really much to worry about. “If I went and cultured the average unwashed coffee cup, of course I would find bacteria.” Starke said. “But remember the vast majority came from the person who used the cup.” Even if you drink from it while sick, it’s pretty hard to re-infect yourself with the same cup; most viruses don’t live long outside the body, which means that just letting your cup live in its own dirt may be a safer bet than the alternative; cleaning it with the disgusting sponge(海绵) in the office kitchen “The sponge in the break room probably has the highest bacteria count of anything in the office.” Starke said if the idea of not washing horrifies you , just stick the sponge in the microwave before using. Otherwise, though, reel free to continue your lazy ways without guilt.

1.What does the passage intend to tell us?

A. It is harmful to drink coffee with sugar.

B. It’s okay not to wash your coffee cup regularly.

C. The hot water contributes to the bacteria growing.

D. Drinking from unwashed coffee cups causes diseases easily.

2.What do we know from Stark’s words?

A. The coffee cup in the office must be put in the microwave to clean.

B. It’s easy to get infected if you often use the same unwashed cup.

C. The coffee cup shouldn’t be shared in the office.

D. It’s good way to grow bacteria in an unwashed cup.

3.What does the underlined part “your lazy ways” refer to ?

A. Leaving your coffee cup unwashed. B. Sticking the sponge in the microwave

C. Using Paper cups only in the office D. Cleaning your coffee cup with sponge.

4.Where does the passage probably come from?

A. A travel brochure. B. A science magazine.

C. An official statement. D. An entertainment program.
