What is green food? Do you enjoy green food every day? The concept of “green food” was first suggested by the Department of the Ministry of Agriculture in 1990.
Green symbolizes life, health and energy. Nowadays, people demand healthy and fresh food. Having enough food to eat is only a basic requirement, and they need more than this. They want to enjoy unpolluted, safe and nutritious food and eat comfortably. So the government does this through a set of “from the land to the dinner table” quality controls. It requires to change China’s traditional agricultural structures and ensure the food of high quality.
Safe vegetables refers to products without substances harmful to humans. Growing such vegetables requires no strong poisons, thus guaranteeing vegetables fresh and clean. There are strict regulations in place for even applying fertilizer(肥料). The examination of vegetables should reach the state food hygiene(卫生) standard. The following conditions for green food are regulated by the China Green Food Development Center. Firstly, products or raw materials must reach the green ecological environment standard set by the Ministry of Agriculture. Secondly, crop planting, livestock raising, fish breeding and food processing must follow green food operating procedures set by the Ministry. Products must be up to the green food hygiene standard. External packing must be pasted with national standard universal labels, special green food packing decoration and tag regulations.
However, by now, our goal hasn’t been completely realized. When you return home with a full basket, you are still worried about whether what you have bought is green and healthy. Indeed, for the sake of our health, we still have a long way to go.

In real life, the daily struggles between parents and children are around these narrow problems of an extra hour, extra TV show, and so on” said Avi Sadeh, psychology professor at Tel Aviv University. “Too little sleep and more accidents,” he said.
Sadeh and his colleagues found an extra hour of sleep can make a big difference. The children who slept longer, although they woke up more frequently during the night, scored higher on tests, Sadeh reported in the March/April issue of journal Child Development.
“When the children slept longer, their sleep quality was somewhat weak, but in spite of this their performance for study improved because the extra sleep was more significant than the reduction in sleep quality. ” Sadeh said. “Some studies suggested that lack of sleep as a child affects development into adulthood and it’s more likely to develop their attention disorder when they grow older. ”
In earlier studies, Sadeh’s team found that fourth graders slept an average of 8. 2 hours and sixth graders slept an average of 7. 7 hours.
“Previous research has shown children in elementary school need at least nine hours of sleep a night on a regular basis, said Carl Hunt, director of the National Center on Sleep Disorders Research in Bethesda, and high-school-age children need somewhat less, he said, adding the results of insufficient sleep could be serious.
“A tired child is an accident waiting to happen,” Hunt said. “And as kids get older, toys get bigger and the risks higher. ”Hunt also said too little sleep could result in learning and memory problems and long-term effects on school performance.
“This is an important extension of what we already know, ” Hunt said of Sadeh’s research, adding sleep is as important as nutrition(营养) and exercise to good health.
“To put it into reality,” Hunt said, “parents should make sure they know when their children actually are going to sleep and their rooms are conducive to sleeping instead of playing. ”

Healthy knees aren't the main consideration in choosing high heels, but new research says chunky heels are just __________as spindly stilettos (细高跟鞋).
"It takes a long time to feel the effects of knee osteoarthritis (骨关节炎) — and once you do, it is too ]ate," said Dr. Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School's department of physical medicine.
"I compare it to smoking — one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long, "Kerrigan said. "They are better for your feet than stiletto heels, but just as had for your knees."
The idea that high heels are bad for your health isn't new — scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained (扭伤) ankles and back problems.
But in 1998,Kerdgan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage (软骨) surrounding the knee.
The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.
"This study confirms what we all intuitively (直觉地) know that high-heeled shoes of any kind are not good for our health," said Dr. Glenn Pfeifer, a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.

The British National Health Service (NHS) was set up in 1948 and was designed to provide equal basic health care, free of charge, for everybody in the country. Before this time health care had to be paid for by individuals.
Nowadays central government is directly responsible for the NHS although it is administered by local health authorities. About 83 percent of the cost of the health service is paid for by general taxation and the rest is met from the National Insurance contributions paid by those in work. There are charges for prescription and dental care but many people, such as children, pregnant women, pensioners, and those on Income Support, are exempt from payment.
Most people are registered with a local doctor (a GP, or General Practitioner) who is increasingly likely to be part of a health centre which serves the community.
As the population of Britain gets older, the hospital service now treats more patients than before, although patients spend less time in hospital. NHS hospitals—many of which were built in the nineteenth century—provide nearly half a million beds and have over 480, 000 medical staff. The NHS is the biggest employer in Europe although Britain actually spends less per person on health care than most of her European neighbours.
During the 1980s there was considerable restructuring of the Health Service with an increased emphasis on managerial efficiency and the privatization of some services (for example, cleaning). At the end of the 1980s the government introduced proposals for further reform of the NHS, including allowing some hospitals to be self-governing, and encouraging GPs to compete for patients. Patients would be able to choose and change their family doctor more easily and GPs would have more financial responsibility. The political questions continue of how much money should be provided to support the NHS and where it should come from.
小题1: We can know from the first paragraph that ______.

A．the original aim of the NHS was to provide equal basic health care for everybody

B．people didn’t have to pay for health care since the NHS was set up

小题2:What do we know about the NHS?

A．It’s managed by the central government.

B．Its cost is mainly paid for by the National Insurance contributions.

C．It hires more people than any other unit in Europe.

D．Fewer patients go to its hospitals than before because they spend less on health care.

小题3: All the following statements about GPs are true except that they ______.

A．take care of the local people’s health

B．often take part in competitions to see who is the best

C．work under high pressure nowadays

D．have more responsibilities than before

小题4:What does the underlined word “exempt” probably mean?

小题5:The biggest problem for the NHS is ______.

A．many hospitals are too old to be used

Space travel is definitely bad for astronauts’ bones, reducing their bone density(密度) after only a month of weightlessness, according to French research published on Friday.
Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss continued throughout space flights.
“Bone loss was especially striking in four astronauts, ” the scientists reported in the Lancet Medical Journal.
They measured the bone mineral density (BMD) of bones in the forearm(前臂) and lower leg of the astronauts who had spent one to six months in space.
The BMD loss was significant in the tibia(胫骨) of the lower leg, a weight-bearing bone, but barely changed in the radius(桡骨) of the forearm. “Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton (骨架) are similarly affected by space conditions, ” they added.
Without gravity the body isn’t bearing any weight so there is no need for calcium (钙) which makes bones strong, and it becomes empty into the bloodstream.
The research team suggested in future scientists should try to determine if the loss of bone density was only on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.
小题1:French scientists did their research on Russian astronauts, because _______.

A．they only cared for the Russian astronauts

B．they were not interested in their own astronauts

C．the Russian government invited them to do their research

D．the Russian astronauts worked in space for a long time

小题2:Scientists have found that _______.

A．the BMD loss may cause serious illness to astronauts

B．the BMD loss may cause some change in astronauts’ bodies

C．astronauts shouldn’t care about the BMD loss

D．astronauts should take some calcium before space travel

小题3:What cause the BMD loss to astronauts, according to this passage?

A．The food they eat in space.	B．The drinks they take in space.
C．The temperature in space.	D．The gravity in space.

小题4:In the third paragraph, the word “striking” means ______.

According to a recent article in The Wall Street Journal, we might all be braggarts(大话王) in this competitive society addicted to social networking.
Take a close look at your socialnetworking sites. Do you like to post photos of yourself in restaurants to show others what an exciting life you have? Or do you like to write about how happily in love you are? Or perhaps you are of the subtle type who constantly complain about jobs but really just want to impress others with your important position.
According to the results of a series of experiments conducted by Harvard University neuroscientists(神经科学家), the reward areas of our brain——the same areas that respond to “primary rewards” such as food ——are activated when we talk about ourselves. We devote between 30 to 40 percent of our conversation time to doing just that. Unfortunately, Bernstein says, some people can't tell the difference between sharing positive information that others might actually want to know and direct bragging. She suggests that bragging involves comparison, whether stated or implied.
“We are expected to be perfect all the time. The result is that more and more people are carefully managing their online images”. says Elizabeth Bernstein, a columnist with the Wall Street Journal.
But the issue is not limited to the Internet. In a fiercely competitive job market we must sell ourselves on multiple platforms and show that we are better than others. In fact, we have become so accustomed to bragging that we don't even realize we are doing it, says Bernstein. This is harmful to our relationships and puts people off.
Bernstein talked to some experts who said that people brag for all sorts of reasons: to appear worthy of attention; to prove to ourselves we are doing fine and that people who said we would fail are wrong; or simply because we're excited when good things happen to us.
“Feel sorry for them, because they're doing this unconscious, destructive thing that won't help them in the long run，” said Professor Simian Valier, a research psychologist at Washington University.
小题1:The underlined word “subtle” in Para.2 is closest in meaning to “________”．

A．hidden	B．apparent
C．outstanding	D．simple

小题2:Which of the following is one of the features of braggarts?

A．They control conversation and only talk about themselves.

B．They know well how to share positive information.

C．They selfpromote to stand out in their career.

D．They don't pay much attention to their online image.

小题3:What can we infer from the passage?

A．Braggarts make a good first impression but the effect decreases over time.

B．People who like bragging know what they are doing.

C．Braggarts always adopt comparison directly to show they are excellent.

D．They care much about the feelings of others when talking.
