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.

Cricket
About the game:
Cricket is a game played between two teams, generally of 11 members each. Essentially, it is single combat, in which an individual batsman does battle against an individual bowler, who has helpers known as fielders. The bowler throws the ball from one end of the 22-yard pitch in an attempt to dismiss (send out) the batsman by hitting a target known as the wicket at the other end, or by causing the batsman to hit the ball into the air into a fielder's grasp. The batsman attempts to defend the wicket with the bat and to score runs, by striking the ball to the field boundary, or far enough from the fielders to allow the batsman to run to the other end of the pitch before the ball can be returned. There are always two batsmen on the field, each to take a turn as required. When all but one of the batting team, altogether eleven of them, have been dismissed, the teams' roles are switched. After all the players required to bat on both sides have done so either once or twice (which can take from a few hours to five days) the total number of runs accumulated determines the winner. But sometimes there isn't one.
Important terms of cricket:
Batsman: A player who uses a bat to hit, or guide the ball after it has been bowled, usually for the purpose of scoring runs.
Boundary: Indicates the outer limit of the playing area.
Bowler: Refers to a player who’s primarily good at throwing a ball to a batsman. The basic goal is to get the ball past the batsman and break the wicket behind him with it and thus cause the batsman to be dismissed.
Catch: If a fieldsman catches a struck ball before it touches the ground, that is a catch and the batsman is out.
Fielder: A player placed within the field, with the object of stopping the batting team from scoring runs, also called “fieldsman”.
Four: If the ball is hit to bounce or roll over the boundary, this is a "boundary four"; four runs are added.
Run: The method of scoring during a game of cricket. Also refers to a single unit of score.
Six: If the batsman hits the ball clear over the boundary on the fly, six runs are added to the score.
Umpire: A person appointed to rule on plays in cricket.

Eat healthier. Exercise twice a week. Read more books. Lose weight. We make the same resolutions(决心) every year, but most of us fail, dying out after only a few days or , at best, weeks. Even the most successful among us crash and burn when it comes to personal change. President-elect Barack Obama struggles to remove his cigarette habit.
Professionals who help people make changes in their lives suggest the change is determined not by one's surroundings, but one's mind. Beginning with small goals or steps usually leads to a bigger payoff later, they say. But they caution that the experience is different for everyone.
"People are more likely to make positive changes in their lives not only when their friends do, but when their friends of friends do, and when their friends of friends of friends do," said Nicholas Christakis, a professor of medical sociology at Harvard University. "People are better able to make changes in their lives - lose weight, quit smoking, become happy - when they do this with a large number of other people, and so taking advantage of your social network ties can result in a magnification of your own efforts."
Jhonny Augustin understands that well. His resolution for 2008 was to shed 30 pounds from his 237-pound frame. But the change didn't come easily. He said,"I'm a huge procrastinator, I kept putting it off until tomorrow. I didn't get to do it until the summer." However , Augustin got inspired when he saw his older brother working out. Today, Augustin weighs 190 pounds.
“Of course, change can happen only if people don't set their expectations too high or try to tackle too many changes at once; one of the biggest mistakes we make is setting unrealistic goals, ”said Dalia Llera, a psychologist and associate professor of counseling and psychology at Lesley University. "You can't accomplish in a few weeks what you haven't accomplished in a few years," said Llera.

When people lose legs after accidents or illnesses, emergency care and artificial limbs（假肢）often allow them to walk again. Newts （蝾螈） in the same situation, on the other hand, can grow limbs back on their own! Scientists have known for a long time that certain animals can re-grow limbs, but they haven’t quite figured out how these creatures do it.
Researchers have now come up with some new ideas. Their work may give people the ability to re-grow lost limbs. The researchers started with two simple experiments：when you cut a newt’s leg at the ankle, only the foot grows back；when you cut off a leg at the very end, the whole leg grows back. In both cases, the re-growth begins with stem cells. Stem cells can develop into nearly any type of cell in the body.
How do a newt’s stem cells know when to grow only a foot and when to re-grow a whole leg?
This question relates to another mystery. In newt’s, a cut-off leg will grow back only if the nerve bundle（神经束）in it also grows back , but if something prevents the nerve bundle from growing, the stem cells at the wound won’t re-grow a new leg.
In its study, a British team focused on a protein called n-AG. When the team prevented nerves in a limb from growing, but added the n-AG protein to stem cells in the limb, the limb still re-grew. That protein seems to guide limb re-growth. People have proteins that are similar to n-AG. Further research into these materials may someday help human limbs recover by themselves.
40. In the experiments, the researchers cut off a newt’s foot or leg to find out _____.
A. what stem cells were                    B. whether they would grow back
C. how long it would take to re-grow    D. how they would re-grow
41. A newt will re-grow its leg if _____.
A. its ankle was cut off but the nerve bundle was good
B. its leg was cut off and the nerve bundle stopped growing
C. its leg was cut off and the nerve bundle could grow back
D. its ankle and the nerve bundle were cut off
42. What do the underlined words “these materials” refer to?
A. Nerve bundles and proteins.         B. Proteins similar to n-AG.
C. Stem cells and proteins.              D. Stem cells and nerve bundles.
43. The first sentence of the passage _____.
A. acts as a lead–in                      B. shows where researchers got their new ideas
C. states the author’s opinion           D. describes the result of researchers’ studies

The reasons for a person’s becoming an alcoholic have often been debated by psychologists and other scientists. But recent studies suggest that the problem of alcoholism(酒精中毒) should also be the focus of investigation by biologists.
While such things as hard jobs, boredom, and unhappiness can lead to alcoholism, researchers at a prominent university have found that there may also be a genetic factor involved in alcoholism. In the study, children of alcoholic parents were surveyed. The result showed that the children of alcoholic parents were more likely to become alcoholics themselves than were children of non-drinking parents.
This evidence in itself is not conclusive（令人确信的）about anything. After all, it may be the constant exposure（接触）and easy access to alcohol that cause the children of alcoholics to become alcoholics themselves. But there is more evidence. The study found that children born of alcoholic parents but raised by non-drinking foster（抚养的）parents also were susceptible to alcoholism. This group of offspring（后代）was more likely to take up drinking than youngsters who were born of and raised by non-drinking parents.
Other evidence found in the study suggests that environment does not play as important a role in the development of alcoholism as had been previously thought. The study found that the likelihood of alcoholism was better predicted from the characteristics of the parents than from such environmental characteristics as type of job or level of income.
63. What is the main point of the passage?
A. To describe the environment in the development of alcoholism.
B. To study the psychological factor in the development of alcoholism.
C. To describe how the children of alcoholic parents become alcoholics themselves.
D. To describe the close link between genetic make-up and alcoholism.
64. According to the passage, what can bring about alcoholism?
A. Biologists’ investigation.                       B. Non-drinking parents.
C. Hard jobs, boredom and unhappiness.             D. Foster parents’ raising.
65. According to the findings of the study, who would be the most likely to become an alcoholic?
A. A person who had a hard job.
B. A person who was born of alcoholic parents.
C. A person who was raised by drinking foster parents.
D. A person who was born of and raised by non-drinking parents.
66. According to the passage, what should the problem of alcoholism be treated as?
A. A psychological problem.
B. An environmental problem.
C. A biological problem.
D. An educational problem.

Imagine your body is like the house you live in．Every day, your family creates rubbish．The rubbish builds up until it is put out for the weekly garbage collection．
Now, say you put three bags of garbage out．but because one of the collectors was away sick, only two bags are collected．You take the leftover bag inside to be put out again next week．The following week you put on another three bags．plus the leftover bag from last week．But again, only two bags are collected．Imagine this cycle is repeated over the following weeks．
This is a simple description of what happens to your body when your kidneys （肾脏）don't work efficiently．Your body is nol thoroughly emptied of waste products．Other areas of the bodv such as blood pressure and red blood cell production are affected and the insidious process that may lead to kidney failure begins．
It's not uncommon for people to lose up to 90% of their kidney function before deveoping any symptoms．There may be no warning signs. This makes early detection （诊查）difficult．
Kidney's main job is to remote toxins（毒素） and unwanted water from our blood．Every day our kidneys clean an average of 200 litres of blood．Kidney failure may be a gradual and silent process, going unnoticed because there is no apparent pain．
Research shows that more than 35% of the patients requiring dialysis （透析）do not see a kidney specialist before they have to do so．Some risk factors for kidney disease such as age and genetic make up are out of our control; however, some changes in lifestyle may help prevent kidney damage．Two major risk factors for kidney disease, diabetes （糖尿病）and high blood pressure, have been on the rise over the last few decades．Both conditions are chiefly affected by being overweight and not getting enough exercises, which are the potential risk factors for the kidney disease．
66．The author gives the example of the house we live in to indicate that ______．
A．it doesn't matter much if the waste in our body is not emptied in time
B．our body will not produce any waste if our kidneys work efficiently
C．it's important for our body to empty the waste in time every day
D．it's safe and harmless for our body to keep some waste
67．The underlined word “insidious” in Paragrap 3 means          .
A．smooth and safe                 B．apparent and fast
C．gradual and unnoticed       D．long and painful
68．We can infer that when we find some symptoms related to our kidneys,          .
A．the kidney failure begins
B．the kidneys can still work properly
C．we have lost about 10% of kidney function
D．the kidneys may have been seriously damaged
