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 over-consumption in the greenest way possible, 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 has 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 burying 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, few of them are coming round to the idea that this cannot continue, encouraging customers to reuse their plastic bags, for example.

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 is also applied 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 materials are collected. We need to face the wastefulness of our consumer culture, but we have a mountain to climb.

1.What does the underlined phrase "over-consumption" refer to?

A. Using too much packaging.

B. Recycling too many wastes.

C. Having more material than is needed.

D. Making more products than necessary.

2.The author uses figures in Paragraph 2 to show_______.

A. the tendency of cutting household waste

B. the increase of packaging recycling

C. the fact of packaging overuse

D. the rapid growth of supermarkets

3.According to the text, recycling_________.

A. means burning packaging for energy

B. helps control the greenhouse effect

C. is the solution to gas shortage

D. leads to a waste of land

4.What can be inferred from Paragraph 4?

A. Unpackaged products are of bad quality.

B. Supermarkets care more about packaging.

C. Other products are better packaged than food.

D. It is improper to judge quality by packaging.

5.What can we learn from the last paragraph?

A. Needless material is mostly recycled.

B. Fighting wastefulness is difficult.

C. People like collecting recyclable wastes.

D. The author is proud of their consumer culture.

Today, Tony and I went to the countryside by the bus for the Strawberry-picking Festival. It starts at 8:00 in the morning. After the organizer introduced the rules of the festival, we led into the strawberry garden by some girls. While walking along the road, we saw beautiful flowers and heard birds sang.

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

Born in September, 1897, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.

Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（設備）to help save the lives of wounded soldiers.

Traditionally, across the world, boys and girls attend a mixed school, where they study together. But boys' schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music.

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 correspond to(和…相符) 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, head master of Eton, warned that boys were being failed 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 girls 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 "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 genre （類型） in which violence and sexism are major themes," James wrote.

Single-sex education also made it less likely that boys would feel that they had to 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.The author believes that a single-sex school would __________.

A. force boys to hide their emotions to be "real men"

B. help boys to be more competitive in schools.

C. encourage boys to express their emotions more freely

D. naturally strengthen boys’ traditional image of a man

2.It is commonly believed that in a mixed school boys __________.

A. behave more responsibly.B. grow up pore healthily.

C. perform relatively better.D. receive a better education.

3. According to Abigail James, one of the advantages of single-sex schools is __________.

A. teaching can be tailored to suit the characteristics of boys

B. boys can focus on their lessons without being distracted

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

D. teaching can be designed to promote boys' team spirit

4. What does the underlined word “acute” in paragraph 8” mean?

A. lovelyB. sharp

C. seriousD. dull

Traditional Japanese food is surely one of the healthiest and most delicious in the world, and fortunately for most of us, foods like tofu, sushi and even green tea are now familiar and can be found easily out of Japan. As a national cuisine(烹飪), thanks to many social as well as political changes, Japanese food has greatly developed over the past few centuries. In ancient times, when much of the traditional cuisine was influenced by Korean and Chinese cultures, Japanese cuisine slowly changed with the start of the medieval(中世紀的)period, which brought along with it new tastes.

With the coming of the modern age, a great many changes took place and the Japanese cuisine was influenced greatly by Western culture. However, the traditional Japanese food of today is still very like what existed toward the end of the 19th century. This would mean that a large part of the Japanese cuisine includes those foods whose cooking methods and ingredients(原料)have been introduced from other cultures, but which have since then been experimented with and developed by the Japanese themselves.

The thing about Japanese food is that you either will love it or will completely look down upon it. With traditional Japanese food, there is no such thing as an in-between. However, chances are that if you hate Japanese food, then you probably haven’t even tasted real Japanese food or you simply haven’t given yourself the chance to like it. Unlike other cuisines, Japanese food is not something that you will appreciate after having only a bite. Like wines and cigars, Japanese food needs time to be liked.

A. advises us to eat healthy food is so healthy

B. explains why Japanese food is so healthy

A. That most people know how to prepare tofu and sushi themselves.

B. That most traditional Japanese food can be enjoyed everywhere.

D. That Japanese food like tofu, sushi and even green tea is not strange to us.

A. Japanese food changed most during the medieval period.

B. Japanese food has been greatly influenced by other cultures.
