Burn Calories in Your Sleep?
The weight-loss world is full of assertions(断言), rarely proved, that some pill can help you “burn calories while you sleep.” But a recent Dutch study reports that it can be done – simply by eating more lean protein(无脂肪蛋白质).
Researchers report for the first time that consuming nearly a third of daily calories as lean protein – for example, lean meats without the skin – speeds up a person’s metabolism(新陈代谢) during sleep and that higher protein intake increases the burning of calories and fat during the day. Plus, when the study’s participants, who were all women of healthy weight, ate more protein, they felt fuller, more satisfied and less hungry than when they consumed a diet with the amount of protein, about 10 percent of calories.
The findings suggest that adding lean protein to your daily food “enables you to reach the same level of satiety(过饱)that you are used to with about 80 percent of your normal energy intake,” notes Margriet Westerterp-Plantenga. “That means you can eat about 20 percent less and still have the same satiety.”
What gives protein its caloric edge? It’s more difficult for the body to metabolize protein than either fat or carbohydrates(糖类). The body also doesn’t store protein as efficiently as it does carbohydrates or fat. So protein is more likely to be burned and that in turn requires more oxygen and helps you feel satisfied in the hours after eating.
But the latest findings don’t mean it’s time to dust off those high-protein diet books. The current study limited fat to about 30 percent of daily calories, and included 40 percent of calories as healthy carbohydrates, including fruit and vegetables. For example, lunch included bread, soy milk, fruit yogurt, tuna in water, tomatoes, cucumbers, feta cheese and salad dressing.
54. According the first paragraph, we know that ______.
A. there’re few studies on weight-loss in the world
B. many studies on weight-loss only cheat customers
C. only few studies are useful for weight-loss
D. there’re few studies about lean protein
55. According to the passage, lean protein can help burn calories while you sleep because ______.
A.it can slow down a person’s metabolism
B. it’s difficult for the body to metabolize
C.it will not make you feel full
D. it’s easy to be stored in the body
56. The underlined phrase “dust off” in the last paragraph means ______.
A. get rid of B. put away
C. get ready to rewrite D. get ready to reuse
57. The passage is mainly to tell readers ______.
A. there is a good diet for weight-losers
B. you can burn your calories in your sleep
C. high-protein diet books will be popular
D. choosing right food is of great use

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.
64. What’s the right order of the four kinds of people (1—4 ) on the cricket ground (see picture on the right ) ?
A. bowler; umpire; batsman; fielder B. batsman; umpire; fielder; bowler
C. fielder; bowler; batsman; umpire D. bowler; umpire; fielder; batsman
65. What happens when the batsman hits the ball, which first touches the ground inside the pitch and rolls quickly over the boundary to one of the viewers outside the cricket ground?
A. The batsman gets dismissed. B. The batting side gets four runs.
C. The batting team gets six runs. D. The bowler’s team gets four runs.
66. We can learn from the passage that ________.
A. the side which has all its batsmen dismissed wins the game
B. the side which dismisses all batsmen of the other side wins the game
C. the side which gets more runs than the other side wins the game
D. the side which dismisses more of the other side’s batsmen wins the game
Fresh flowers actually continue to grow while in a vase.So in order to keep flowers fresh, you need to consider what the flowers need to grow and stay healthy.Flowers need water, light, and food.Besides, you need to be aware of a few precautions to take.
Distilled water(蒸馏水) is the best kind of water to use for fresh flowers, because there are no chemicals in it.Change the water for your fresh flowers every day or no less than every 2 days to prevent bacteria(细菌) building up.Cut the stems under water again before putting them back in the vase, so that they will be able to draw water up easily.
Keep your fresh flowers out of direct sunlight.At night, put them in the fridge.This will prolong their life.Adding commercial flower food to good water is probably the best method of keeping flowers fresh.Some people put sugar in the water for food.That is OK, but commercial flower food has bacteria-killing ingredients, which can make the water more acidic(酸性的).If you want a more natural food for your fresh flowers, try water that has been specially treated.That solution will also give the water acidity, sugar, and bacteria-killing ability.
Keep your fresh flowers away from fruit.Fruit gas, or ethylene, will reduce the life of your fresh flowers, making them get older faster.Ethylene is what makes fruit ripen.It is given off by dead flowers, too, so be sure to remove them.
If you follow these tips, your fresh flowers will last a long time and beautify any room in which you put them.
1.What does the underlined word precautions in Paragraph 1 mean?

Moods, say the experts, are feelings that tend to become fixed, influencing one’s outlook for hours, days or even weeks. That’s great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.
Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology(药理学)offers a lot of tranquilizers(镇静剂)What many people don’t realize, however, is that scientists have discovered the effectiveness of several non-drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don’t head for the drug-store but try the following methods.
Of all the mood-altering self-help techniques, aerobic exercise seems to be the most efficient cure for a bad mood. “If you could keep up the exercise, you’d be in high spirits, ” says Kathryn Lance, author of Running for Health and Beauty.
Researchers have explained biochemical and various other changes that make exercise compare favourably to drugs as a mood raiser. Physical exertion such as housework, however, does little. The key is aerobic exercise—running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body’s use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.

In the 19th century, only one home out of six had a bathroom. A child took only one bath a week. On Saturday nights, children all lined up for their turns to wash in a wooden bathtub in the kitchen. Mothers had to boil the water on the stove and carry it over to fill the bathtub. It’s no wonder that children could not jump into a bathtub as they do today.
When the first bathtubs were introduced, even their makers weren’t sure whether the new fashion would last. They advertised their products as water containers that “could be used as bathing tubs”.
The bathtub became popular in America shortly after World War I. By then most middle-class families had indoor taps. At first most bathtubs were made of wood, but as the popularity of the product increased, so did the creativity of bathtub makers. Before porcelain(瓷) bathtubs there were rubber ones like the plastic swimming pools kids use today. In the past few years owners often invited guests to see them. They told their friends how wonderful baths in these bathtubs could be.
Now doctors no longer warn that bathtubs carry diseases. Instead, they tell their patients about the benefits of frequent bathing in the bathtubs. Maybe one of the best reasons why doctors encourage frequent trips to the bathtub is that bathed patients smell better!
47. Many doctors in the past were against using bathtubs because ______.
A. they didn’t have their own bathtubs
B. they thought bathtubs could carry diseases.
C. the children might hurt themselves in the bathtubs
D. bathtubs were too expensive for the common families
48. Why couldn’t children jump into a tub in the 19th century as they do today?
A. It was unhealthy to do so. B. The bathtubs were not enough.
C. Mothers were always busy. D. The bathtubs were made of wood.
49. Which of the following is true according to the text?
A. Some different materials can be used to make bathtubs.
B. In the 19th century only one home out of seven had a bathroom.
C. The bathtub became popular when they were introduced to the market.
D. Children prefer the bathtubs made of plastic to those made of porcelain.
50. It can be inferred from the last paragraph that ______.
A. all the doctors have bathtubs in their homes
B. the doctors have realized the advantages of bathtubs
C. the doctors will make lots of money by advertising bathtubs
D. the patients should take a bath before going to see a doctor
