A
More than one-third of adults in the United States are obese. In fact, over obesity has reached such proportions that one big-city mayor has gone about banning large-sized, sugary soft drinks and the First Lady has been on a campaign to control the dietary offerings in public schools.
Even many adults who do not fit the clinic definition of obesity are still overweight, and a large percentage are looking for the best ways to lose weight.
Reducing pounds largely comes down to the two-sided factors of diet and exercise. Not carrying out the first one enough, and not getting enough of the second one, ends up giving the individual a recipe for being overweight.
Advising someone to eat less and exercise more might be the easiest advice possible, but it’s also, partially, an oversimplification. Dieting has more to do with the types of food you eat than how much you eat. Reduce the amount of red meat in your diet. If you don’t want to eliminate red meat altogether, choose cuts of meat with less fat content. Limit your intake of salt and starches. If you’ve got to have potato chips alongside your sandwich at lunch, choose the baked potato chips that contain less fat than the deep-fried chips. You might find you’re really not sacrificing that much in terms of taste.
A diet rich in fruits, vegetables, egg whites, fish and nonfat dairy products will certainly aid in the mission of losing weight. Drink more water and less sugary drinks. If you have to have a soda, a diet soda is a better option, but seltzer is an even better choice than that.
It’s important—if not always easy—to make sure you get at least some physical activity each and every day. If your feet won’t allow for a regular jogging regimen, then make sure you take lots of walks. Next time you need to mail a letter, walk to the mailbox instead of driving. Try to work in a daily walk in your neighborhood.What is the closest meaning of the underlined word “proportions” ?

Rumour（谣言）is the most primitive way of spreading stories--- by passing them on from mouth to mouth. but civilized countries in normal times have better sources of news than rumour. They have radio, television, and newspapers. In times of confusion（混乱）, however, rumour appears and becomes widespread. At such times the different kinds of news are in competition: the press, television, and radio against the grapevine.
Especially do rumours spread when war requires control on many important matters. The normal news sources no longer give out enough information. Since the people can not learn through legal channels all that they are anxious to learn, they pick up "news" wherever they can and when this happens, rumour grows.
Rumours are often repeated even by those who do not believe the tales. There is an interest about them. The reason is that the cleverly designed rumour gives expression to something deep in the hearts of the victims --- the fears, doubts, forbidden hopes, or daydreams which they hesitate to voice directly. Pessimistic（悲观的）rumours about defeat and disasters show that the people who repeat them are worried and anxious .Optimistic rumours about record production or peace soon coming point to self- satisfaction or confidence---and often to over- confidence.The author suggests that, in times of confusion, man often __________.

With the start of the new semester students around the country exchange their fun and fashionable clothes for boring school uniforms.
"The uniform makes us look like a bunch of clones, especially when we are doing morning exercises in the playground, "said Qing, a Senior 2 from a high school in Shanghai. "But we are not exactly the same from the top to the bottom. The boys wear different sport shoes and girls have different decorations ( 装饰品 )in their hair. These are the areas where you can express yourself" said Qing.
Although it might be strange for boys to talk about fashion, they do care about what they wear in school, especially shoes, according to Qing.
"Nike and Adidas basketball shoes, although they are still the must for many of my friends ,are becoming out-of-date,” added. He explained, "Since Liu Xiang ran so fast in Athens, running shoes are becoming popular in this autumn."
"Still in fashion are the various baseball caps and American-style T-shirts with random English words printed on them, "said Qing. "The accuracy ( 准确性 )of the written message isn't important. Often, the words are misspelt . Sometimes they do not even make sense “ Qing said with a smile.
Besides sports shoes and T-shirts, styles and colours of school bags are another opportunity for students to express their taste in fashion. Some bags are made more eye-catching by decorating them with small hanging dolls. Other fashionable items are the colourful drink contains which are now popular among girls this semester.

A man once said how useless it was to put advertisements in the newspapers. “Last week,” said he, “my umbrella was stolen from a London church. As it was a present, I spent twice its worth in advertising ,but didn’t get it back ”
“How did you write your advertisement ?”asked one of the listeners ,a merchant .
“Here it is,” said the man ,taking out of his pocket a slip cut from a newspaper. The other man took it and read, “Lost from the City Church last Sunday evening a black silk umbrella .The gentleman who finds it will receive ten shillings on leaving it at No 10 Broad Street .”
“Now ,”said the merchant, “I often advertise ,and find that it pays me well .But by the way in which an advertisement is expressed is of extreme importance .let us try your umbrella again ,and if it fails ,I will buy you a new one. ”
The merchant then took a slip of paper out of his pocket and wrote :“If the man who was seen to take an umbrella from the City Church last Sunday evening doesn’t wish to get into trouble, he will return the umbrella to No. 10 Broad Street .He is well known .”
This appeared in the paper ,and on the following morning ,the man was astonished when he opened the front door. In the doorway lay at least twelve umbrellas of all sizes and colors that had been thrown in and his own was among the number. Many of them had notes fastened to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter This is a story about ________.

Everywhere man is altering the balance of nature．He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously．He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization．He exterminates some species on a large scale, but favours the multiplication of others．In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million．
Many of these changes which he has brought about have had unforeseen consequences．Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers’ wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece?
These are spectacular examples; but examples on a smaller scale are everywhere to be found．We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested．We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes．We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock．The following examples except ________ reflect man altering the balance of nature．
| A．man is covering huge areas with new kinds of plants |
| B．man is facilitating the spread of animals into new regions． |
| C．man is killing some species on a large scale |
| D．man is getting to know the importance of keeping the balance of nature． |
What had a piece of Canadian waterweed cause?
| A．Eastern Australian was overrun with forests． |
| B．Half the waterways of Britain blocked for a decade． |
| C．In parts of central Africa, the land reduced to a semidesert． |
| D．Disease-sleeping has been caused． |
What have spread diseases?
| A．Disease-sleeping sickness． | B．Measles． |
| C．Improved communications． | D．Malaria． |
We make a nature sanctuary for rare birds but __________
| A．some common and hardy kind of bird multiplies |
| B．rare kinds multiply |
| C．all bird multiply |
| D．no bird multiply |
The main idea of the passage is _________．
| A．that man is deliberately destroying the balance of nature |
| B．that man has foreseen the consequences of altering the balance old nature |
| C．that improved communications have changed history |
| D．that man is altering the balance of nature |
An annoying problem for humans, who like to boast (夸耀) about all the distant planets and moons we have explored, is that we've never taken a good look right under our noses. The inside of the earth is relatively close, but how can we get there?
The deepest oil well enters a mere six miles into the crust (地壳) (the center of the earth is about 4,000 miles deeper). Russian scientists dug the deepest hole in Siberia, but bottomed out at about 7.5 miles below the surface. The Mohole project, a U.S. plan in the 1950s, called for drilling a hole 25 miles down to the boundary between the hard rocks of the crust and the soft mantle (地幔). Sadly the project involved government supporting.
It gets harder and harder to drill deep into the earth because rocks get softer and softer. Hard but easily broken at the surface, rocks become plastic at depth, and the pressure caused by the weight of the overlaying crust --- about 52,800 pounds per square inch at a depth of ten miles, makes further drilling impossible.
What little we know about the inside of the earth (like the fact that there's a crust, a mantle, and a core) comes from indirect evidence, such as the analysis of earthquakes.
So maybe it's time for a thorough new method to explore the earth's inside. Scientist David Stevenson says we should forget about drilling holes. Instead, we should open a crack (裂缝).
Stevenson suggests digging a crack about a half mile long, a yard wide, and a half mile deep (not with a shovel) but with an explosion on the scale of a nuclear bomb. Next, he'd pour a few hundred thousand tons of molten (熔化的) iron into the crack, along with a robot. The iron, thicker than the surrounding crust, would move downward at about 16 feet per second, carrying the robot with it and opening the crack deeper and deeper. The iron mass would drop for about a week and 2,000 miles to the outer edge of the earth core, the robot sending out data to the surface.
Stevenson compares his idea to space exploration. "We're going somewhere we haven't been before,"he says. "In all possibility, there will be surprises.”
This idea can probably be put in the drawer marked with Isn't Going To Happen. The robot would have to survive temperatures that would melt pretty much anything. But Stevenson's idea may inspire a new look at an old problem. Great things can come from what seems like impossible ideas.Going inside the earth is _____ than going into space.
| A．more interesting | B．more possible | C．easier | D．more challenging |
How deep have we gone into the earth until now?
| A．6 miles. | B．4,000 miles. | C．7.5 miles. | D．25 miles. |
Which of the following is TRUE about David Stevenson's idea?
| A．It is an inspiring but not practical idea now. |
| B．It is a practical proposal that has come into use now. |
| C．It is a good proposal that will soon be put into practice. |
| D．It is a false theory that cannot be carried out at all. |
What might be the most suitable title for the text?
| A．An Annoying Problem for Humans |
| B．To the Center of the Earth |
| C．The Mohole Project |
| D．David Stevenson's Proposal |
