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 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 , 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 is 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 realise just how much unnecessary material are collecting. We need to face the wastefulness of our consumer culture, but we have a mountain to climb. What does the underlined phrase “over-consumption” refer to?
| A．Using too much packaging. |
| B．Recycling too many wastes. |
| C．Making more products than necessary. |
| D．Having more material than is needed. |
The author uses figures in Paragraph 2 to show _______.

| 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. |
What can we learn from the last paragraph?

People in the United States honor their parents with two special days: Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two days offer a chance to think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child-care.
These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one stands for a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit their graves. On these days, families get together at home and in restaurants. They often have outdoor BBQs for Father’s Day. These are days of fun and good feelings and memories.
Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephones companies and other stores do a lot of business during these holidays. Which is NOT a reason for children to show love and respect for parents?
| A．Parents bring up children. |
| B．Parents give love and care to children. |
| C．Parents pass away before children grow up. |
| D．Parents educate children to be good persons. |
What do you know from the passage?
| A．Mother’s Day and Father’s Day are both in May. |
| B．Not all the children respect their parents. |
| C．Fewer women worked outside the home in the past. |
| D．Fathers are not as important as mothers at home. |
Which do you think is right about “carnation”?
| A．It only has two kinds of color. |
| B．It is a special kind of clothes people wear on Mother’s Day or Father’s Day. |
| C．People can wear carnations only on the second Sunday in June. |
| D．It’s a kind of flower showing love and best wishes. |
What do you think “florists” do?
| A．They sell flowers. |
| B．They made bread. |
| C．They offer enough room for having family parties. |
| D．They sell special clothes for Mother’s Day and Father’s Day. |
Another man-made wonder of the United States was built long before the nation was established.About 900 years ago, the Ancestral Puebloan people built villages high in the walls of canyons in Colorado, where 600 cliff dwellings are now part of the Mesa Verde National Park. 
Visitors can stand at the top of the mesas and look into the dwellings almost hidden in openings of the rock walls. The Puebloan people cut small steps into the rock, which connected buildings containing hundreds of rooms.
The rock walls have protected the buildings from severe weather in the area; therefore, they remain mostly unchanged in the hundreds of years since they were built.
Our final man-made wonder is in the northwestern city of Seattle, Washington. The Space Needle was built as the central structure for the 1962 World's Fair.
The 184-meter-tall structure was designed by Edward Carlson, which has a wide base on the ground, with its middle narrow and a large ring-like structure on top. The structure was meant to look like a "flying saucer," a vehicle that was popular in science fiction space travel stories. The saucer includes an observation area and eating place. The restaurant slowly turns to provide visitors with a 360 degree view of Seattle.
The Space Needle, only costing about $4,500,000, was not very costly, and was designed and completed in about a year and opened on the first day of the World's Fair.
Today, the Space Needle is the most popular place for visitors to Seattle. And it remains the internationally known symbol of the city. What the passage before this one can be about?
| A．Some natural wonders in the world. |
| B．Sightseeing in the US. |
| C．Some other artificial wonders in the US. |
| D．American geography. |
What does the underlined word “dwelling” mean?
| A．village | B．house | C．canyon | D．step |

A. It is a man-made wonder in Washington, D.C..
B. Edward Carlson built the structure.
C. It has a ring-like structure on top.
D. It remains the internationally known symbol of the US.What is the passage mainly about?
| A．Visiting the US | B．Man-made wonders in the US |
| C．Wonders in the world | D．Famous places in the US |
Why play games? Because they are fun, and a 1ot more besides. Following the rules…planning your next move...acting as a team member…these are all “game” ideas that you will come across throughout your life.
Think about some off the games you played as a young child, such as rope-jumping and hide-and-seek. Such games are entertaining and fun. But perhaps more importantly, they translate life into exciting dramas that teach children some of the basic rules they will be expected to follow the rest of their lives, such as taking turns and cooperating (合作) .
Many children’s games have a practical side Children around the world play games that prepare them for work they will do as grown-ups. For instance, some Saudi Arabian children play a game called bones. Which sharpens the hand-eye coordination（协调）needed in hunting.
Many sports encourage national or local pride. The most famous games of all, the Olympic Games, bring athletes from around the world together to take part in friendly competition. People who watch the event wave flags, knowing that a gold medal is a win for an entire country, not just the athlete who earned it. For countries experiencing natural disasters or war, an Olympic win can mean so much.
Sports are also an event that unites people. Soccer is the most popular sport in the world. People on all continents play it — some for fun and some for a living. Nicolette Iribarne, a Californian soccer player, has discovered a way to spread hope through soccer. He created a foundation to provide poor children with not only soccer balls but also a promising future.
Next time you play your favorite game or sport, think about why you enjoy it, what skills are needed, and whether these skills will help you in other aspects of your life. Through playing hide-and-seek, children are expected to learn to ________.
| A．be a team leader | B．obey the basic rules |
| C．act as a grown-up | D．predict possible danger |

Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri (MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with energy density (密度),” said Jae kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope (放射性同位素) battery can provide power density that is much higher than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, recently the size and thickness of a penny, intended to power various micro/nano-electromechanical systems (M/NEWS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said. “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor (半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure (晶格结构) of the solid semiconductor, ” Kwon said. “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that the battery could be thinner than the thickness of human hair.Which of the following is true of Jae Kwon?
| A．He teaches chemistry at MU. |
| B．He developed a chemical battery. |
| C．He is working on a nuclear energy source. |
| D．He made a breakthrough in computer engineering. |
Jae Kwon gave examples in Paragraph 4 ________.
| A．to show chemical batteries are widely applied |
| B．to indicate nuclear batteries can be safely used |
| C．to describe a nuclear-powered system |
| D．to introduce various energy sources. |
Liquid semiconductor is used to ________ .
| A．get rid of the radioactive waste |
| B．test the power of nuclear batteries |
| C．decrease the size of nuclear batteries |
| D．reduce the damage to lattice structure |
According to Jae Kwon, his nuclear battery ________.

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes (糖尿病), Thomas would need to inject himself with insulin (胰岛素) three times a day for the rest of his life or risk nerve damage, blindness and even death. And if that weren't bad enough, he had no health insurance.
After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar.com, a free online community for diabetics and their loved ones — a place where over 1,100 people share personal stories, information, and resources.
Jason Swencki’s son, Kody, was diagnosed with diabetes at six. Father and son visit the online children's forums(论坛) together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone."
Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
These days, Thomas's main focus is his charity（慈善机构）, Fight It, which provides medicines and supplies to people —225 to date— who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000 — in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only person I know saying people need help now." Which of the following is true of Christopher Thomas?
| A．He needs to go to the doctor every day. |
| B．He studies the leading cause of diabetes |
| C．He has a positive attitude to this disease. |
| D．He encourages diabetics by writing articles. |
Diabeitcrockstar.com was created for _________.
| A．diabetics to communicate | B．volunteers to find jobs |
