John Nash,a Nobel Prize winner and a mathematical genius whose struggle with mental illness was documented in the Oscar-winning film A Beautiful Mind,was killed in a car accident on May 24th, 2015.

Born in West Virginia, Nash displayed a keenness for mathematics early in life,independently proving Femret's little theorem(定理)before graduating from high school. By the time he turned 30 in 1958,he was an unquestionable academic celebrity. At Princeton, Nash published a 27-page thesis that led to applications to economics,international politics, and evolutionary biology

His signature solution-known as a "Nash Equilibrium(纳什均衡)”-found that competition among two opponents,not necessarily governed by zero-sum logic. Two opponents can, for instance,each achieve their maximum objectives through cooperating with the other, or gain nothing at all by refusing to cooperate. It is now regarded as one of the most important social science ideas in the 20th century.

In the late 1950s, Nash began a slide into mental illness. By the time Nash was awarded the Nobel Prize in Economics in 1994, he hadn't published a paper in 36 years. But like a child cured of a nightmare by the switch of a light, Nash recovered from his illness seemingly by choosing not to be sick anymore. He continued to work, travel,and speak at conferences for the rest of his life.

In 2001,the release of the film A Beautiful Mind,based an Sylvia Nasar’s 1998 book of the same name,introduced Nash's unusual life story to an international audience

Ask someone what they have done to help the environment recently and they will almost certainly mention recycling.Recycling in the home is very important of course.However,being forced to recycle often means we already have more material than we need.We are dealing with the results of that overconsumption in the greenest way,but it would be far better if we did not need to bring so much material home in the first place.

The total amount of packaging increased by 12% between 1999 and 2005.It now makes up a third of a typical household’s waste in the UK.In many supermarkets nowadays food items are packaged twice with plastic and cardboard.

Too much packaging is doing serious damage to the environment.The UK,for example,is running out of it for carrying this unnecessary waste.If such packaging is burnt,it gives off greenhouse gases which go on to cause the greenhouse effect.Recycling helps,but the process itself uses energy.The solution is not to produce such items in the first place.Food waste is a serious problem,too.Too many supermarkets encourage customers to buy more than they need.However,a few of them are coming round to the idea that this cannot continue and encouraging customers to reuse their plastic bags.

But this is not just about supermarkets.It is about all of us.We have learned to associate packaging with quality.We have learned to think that something unpackaged is of poor quality.This is especially true of food.But it also applies to a wide range of consumer products,which often have far more packaging than necessary.

There are signs of hope.As more of us recycle,we are beginning to realize just how much unnecessary material we are collecting.We need to face the wastefulness of our consumer culture,but we have a mountain to climb.

1.The author uses figures in Paragraph 2 to show .

A.the tendency of cutting household waste

B.the increase of packaging recycling

C.the rapid growth of supermarkets

D.the fact of packaging overuse

2.According to the text,recycling .

A.helps control the greenhouse effect

B.means burning packaging for energy

C.is the solution to gas shortage

D.leads to a waste of land

3.What can be inferred from Paragraph 4?

A.Unpackaged products are of bad quality.

B.Supermarkets care more about packaging.

C.It is improper to judge quality by packaging.

D.Other products are better packaged than food.

4.What can we learn from the last paragraph?

A.Fighting wastefulness is difficult.

B.Needless material is mostly recycled.

C.People like collecting recyclable waste.

D.The author is proud of their consumer culture.

How to make friends

Choosing friends

Before you make friends,you have to decide who you want to be your friends.Most people like to have friends who like to do the same kind of things as they do.That doesn’t mean you have to be exactly like each other,just that you enjoy some of the same things.Think about your favorite things to do and try to talk to your classmates at lunch or rest about your hobbies.You are sure to find at least one person who’s excited about the same things that excite and interest you,too.

Making friends

●The quickest way to make a friend is to smile.When you smile,people think you are friendly and easy to talk to.It may not be easy at first to smile.But you can practice smiling in front of a mirror.When you look at yourself in the mirror,think if you’d rather talk to your smiling face or your usual scared or angry face.

●One easy way to start a conversation with someone is to say something nice about them.Think about how great you feel when someone says something nice to you.Doesn’t it make you want to talk to him?

●Ask your new friends questions about themselves.It’s the only way to get to know what they’re like and it’s the only way they’ll know that you are interested in them.

●Make sure you have something to add to the conversation,too.When someone asks you a question,do have an answer for them.There is nothing that will stop a conversation quicker than a shrug(耸肩) for an answer.

Activities

After you’ve made a friend who shares the same interests with you,it’s always fun to plan activities together that you’ll both enjoy.Inviting a friend to your house after school is a great way to make your friendship closer.

If you know a game your friend likes to play,you can plan to do that together.When you play a computer game,one person is always left sitting with nothing to do but watch.Not fun.

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict(有瘾的人),” he jokes. “I used to carry a fresh suit to work with me, so I could change if my clothes got wrinkled(有褶皱的).” Today David wears casual clothes (便装) to the office. He hardly ever wears a necktie. “I am working harder than ever.” David says, “and I need to feel comfortable.”

More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday. This became known as “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.

Why have so many companies started allowing their employees to wear casual clothes? “One reason is that it’s easier for a company to attract new employees if it has a casual dress code.” “A lot of young people don’t want to dress up for work,” says Owen Black, the owner of a software company, “so it’s hard to hire people if you have a conservative (保守的) dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Company, 85 percent of employers said that they believe that casual dress improves employee morale (心境, 士气). Only 4 percent of employers said that casual dress has a negative influence on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.”

A. He feels at ease.

B. He looks handsome.

C. He went to a new company.

3.What can we learn from the text?

A. Casual clothes can impress others.

B. People fought for “Casual Friday”.

C. “Casual Friday” used to be popular.

D. “Casual Friday” was given as a prize.

4.What is the advantage of casual office wear?

A. Making workers more easygoing.
