Heavy downpours last month in Rhode Island led to widespread flooding, causing millions of dollars in property damage and leaving thousands homeless. The floodwaters also poured vast amounts of raw sewage (污水) into the rivers and streams that flow into Narragansett Bay.
It sounds like the makings of an environmental nightmare, but in fact it’s just the opposite. To scientists’ delight, the sewage-loaded floodwaters have caused a well-timed growth of phytoplankton, the microscopic creatures that form the foundation of marine food chains. With more food available for fish, clams and other sea creatures, the bay’s fisheries industry is expected to benefit.
In decades past, Narragansett Bay typically experienced a late winter/early spring algal (海藻) bloom that fed creatures up and down the water column. But in recent years, the waters of Narragansett Bay have warmed greatly, interrupting this seasonal event.
Mark Berman, an oceanographer with the National Marine Fisheries Service, said the flood seemed to have sent the bay back to its normal state.
However, local, state and federal officials in Rhode Island have been battling other algal blooms that, by contrast, are causing widespread harm to the Narragansett Bay ecosystem. During summer months, sewage and agricultural runoff flows into the bay, causing large blooms. But instead of becoming food for sea creatures, much of the phytoplankton is consumed by bacteria, which grow fast in the warmer waters. The rapid bacteria growth leads to hypoxia – a decrease of oxygen in the water that can cause large fish kills. One such die-off occurred in 2003, when millions of oxygen-starved fish washed up on the beaches of Narragansett Bay.
The flood’s positive impact will probably be a one-time event, Mr. Berman said. Meanwhile, efforts to curb the harmful summer blooms continue; in 2008, for instance, Providence completed a $359 million sewage tunnel under the city designed to reduce the polluted storm overflow into Narragansett Bay. Scientists believe that the raw sewage flowing into the bay will _______.
| A．pollute the island’s environment | B．cause lots of property damage |
| C．increase the fisheries production | D．destroy the food chains in the bay |
The potential benefit of fisheries industry relies on the _______.
| A．warm temperatures of the bay | B．growth of phytoplankton |
| C．large summer alga blooms | D．consumption of oxygen by bacteria |
People struggle against the summer blooms because they will ________.
| A．pollute the local natural environment | B．increase the production of fishery industry |
| C．cause large fish kills of the bay indirectly | D．provide too much food for sea creatures |
It can be inferred that _______.
| A．money spent on the summer blooms has been wasted |
| B．the government is investing to promote the local fisheries |
| C．research of oceanology should be encouraged |
| D．opinions on the raw sewage impact are currently contradictory |
The underlined word “curb” in the last paragraph can be defined as “______”.
| A．control | B．consume | C．cause | D．cure |
The public commonly associates steroid use with big-time athletics. But the drugs may be even more of a menace to teenagers. The synthetic hormones can stunt a young person’s growth by prematurely closing the ends of the long bones in the skeleton. That means a 1.7 metre, 15-year-old high school student who uses steroids “might get bigger but won’t get any taller”, according to a US doctor.
Nearly seven percent of boys in the US try steroids before the end of high school, according to a 1988 study by professors Charles Yesalis and William Buckley, of Penn State University. The estimate comes from a poll of 3,400 seniors in 46 public and private schools across the US.
“Abusers of Steroids did it to improve their appearance and to excel at sports,” Professor Yesalis said. “Parents, teachers and coaches make boys believe that to be an ideal male you need to have these. Then they say: ‘you can’t play games to have fun; you play games to win.’”
“Such attitudes put many high school athletes at high risk of becoming abusers of steroids,” said Mike Gimbel, director of Baltimore County Office of substance Abuse. “For these athletes, the pressure to perform is incredible,” he said. “It was inevitable that it would seep down to high school level.”The word “big-time” in Paragraph 1 most nearly means “________”.
| A．long time | B．good time | C．top rank | D．modern |
Why are steroids even more of a threat to teenagers?
| A．Because they make teenagers grow too tall. |
| B．Because they make teenagers get too big. |
| C．Because they prevent teenagers from getting taller and taller. |
| D．Because they give teenagers too much pressure. |
Which of the following statements is implied but not mentioned?
| A．School athletes have too much pressure. |
| B．Steroids can help people have lots of muscles. |
| C．The pressure chiefly comes from parents, teachers and coaches. |
| D．Girls are not interested in steroids. |
Which of the following is a good title for this passage?
| A．Drugs and Sports |
| B．The Pressure to School Boys are Too Much |
| C．School Boys are Interested in Drugs |
| D．School Athletes Risk Damage from Drugs |
After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe’s hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15.
Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: “Your computer is now stoned. Legalize marijuana. ” (Regardless of your politics, you don’t want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated—no trading disks, no on-line communication—or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?—as in, pay me $1 million or my virus will destroy your system.
In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened—an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike—on the artist’s birthday.The much-feared M-day was ________.
| A．Friday-the-13th when the eponymous virus was due to strike |
| B．Friday-the-15th when the Maltese Amoeba would be activated |
| C．the previous Friday when Michelangelo virus was due to strike |
| D．the previous Friday which coincided with the artist's birthday |
Computer viruses are ________.
| A．diseases spread from one computer to another by shared disks |
| B．viruses hidden in a computer’s instructions by the designers |
| C．little time bombs hidden in a computer waiting to be triggered |
| D．just those computer programs created by malevolent designers |
Which of the following sayings fits the Michelangelo virus?
| A．A burnt child dreads the fire. | B．The bug’s bark was worse than its bite. |
| C．A barking dog seldom bites. | D．Once bitten, twice shy. |
The author implies that in days to come the viruses might be used ________.
| A．to destroy data | B．to commit crimes |
| C．to commit mischief | D．to create confusion |
Between ten and midnight the United States is politically leaderless—there is no center of information anywhere in the nation except in the New York headquarters of the great broadcasting companies and two wire services. No candidate and no party can afford the investment on election night to match the news-gathering resources of the mass media; and so as every citizen sits in his home watching his TV set or listening to his radio, he is the equal of any other in knowledge. There is nothing that can be done in these hours, for no one can longer direct the great strike for America’s power; the polls have closed. Good or bad, whatever the decision, America will accept the decision—and cut down any man who goes against it, even though for millions the decision runs contrary to their own votes. The general vote is an expression of national will, the only substitute for violence and blood. Its decision is to be defended as one defends civilization itself.
There is nothing like this American expression of will in England or France, India or Russia. Only one other major nation in modern history has tried to elect its leader directly by mass, free, popular vote. This was the Weiman Republic of Germany, which modeled its unitary vote for national leaders on the American practice. Out of its experiment with the system it got Hitler. Americans have had Lincoln, Wilson and two Roosevelts. Nothing can be done when the voting returns are flooding in; the White House and its power will move to one or another of the two candidates, and all will know about it in the morning. But for these hours history stops.Between ten P.M. and midnight the United States is politically leaderless because ________.
| A．the president has been murdered |
| B．the general strike for power has ended |
| C．the government has resigned |
| D．the general vote is being held |
“The great strike for America’s power” in Paragraph 1 refers to ________.
| A．the strike of the government members |
| B．the great vote |
| C．the election campaign |
| D．the strike of the government employees |
The author believes that the decision at the polls will ________.
| A．lead to a civil war | B．result in a general strike |
| C．cause violence and blood | D．be defended by all Americans |
Without the general vote, the author implies ________.
| A．there would be a civil war | B．there would be a general strike |
| C．there would be an election campaign | D．there would be a fierce debate |
What happens to mother-daughter relationships when girls become teenagers. It seems that girls go from playing “dress up”, to arguing with their mothers about how they should dress.
When a girl is 3-4 years old they love to “dress up” in their mothers’ clothes, put on their mothers’ makeup, cook, and do whatever else their mother does. This is the time when she can be classified as being a mama’s girl.
How come girls change so much from childhood to the teenage years? Many parents seek the answer when their daughter becomes a teen. Often when a girl enters high school her behavior changes as well as her physical appearance.
When I was young I always liked playing “dress up”. It made me feel older and more like my mother. Even when I entered middle school, I still depended a lot on my mother to choose and buy my clothes. Once I entered high school there was a big change. To me, my mother’s clothes were no longer “in fashion”, and neither was her opinion. I started becoming interested in boys and tried to improve the way I looked. It was not that I wanted to look cool, I just wanted to look my age.
This is the time that the mother-daughter relationship can take a turn. It’s difficult for a mother to know that her daughter is no longer totally dependent on her.
When the daughter starts wearing revealing clothing, dating, and just wanting to be more independent, a mother starts to feel left out, or not needed. The number of arguments increases, and the number of times when the mother and daughter get along happily decreases.
When these things start to happen, it is a sign that the daughter wants her independence and the freedom to grow up.
When you notice how much your relationship had changed, try to believe positive things come out of the change. Put all the negatives aside and concentrate on what your mother is feeling instead of just on what you’re feeling.
When it seems too hard to handle, take some quiet time and write out your feelings. Maybe at another time, you can share them with your mother and try to find a way to better your relationship as mother and daughter. If you don’t feel comfortable sharing your feelings, at least write them down so you can get them out. It’s better than keeping them bottled up inside.The girls would argue with their mothers because ________.
| A．they need more independence |
| B．mothers want daughters to be mama’s girls again |

From the passage, we know that ________.
| A．the teenage period is a sensitive part in human life |
| B．the parents can’t get the answer why their daughters change a lot |
| C．they can get on well only in talking, no matter what mothers or daughters do |
| D．mothers should concentrate on their own feelings |
A “mama’s girl” will Not________.
| A．dress up in her mother’s clothes |
| B．depend a lot on her mother to choose and buy her clothes |
| C．like wearing revealing clothing |
| D．think her mother’s clothes are in fashion |

| A．a mother starts to feel left out |
| B．it is the time when mother and daughter get on joyfully increases |
| C．she wants to look cool |
| D．All of the above |
I feel very excited at the thought that in another week I shall be with you again on holiday. I have enjoyed my stay in England very much indeed. Mr Brown and classmates are nice to me, but, as they say in England, “There’s no place like home.” and I think you feel this above all at Christmas time.
I am leaving here early on Thursday, the 23rd, and I shall arrive in Basle on Friday morning, so I shall be home somewhere about lunchtime. Can you meet me at the station, as I shall have a lot of luggage?
In some of my earlier letters I have told you all about the other students here. Well, I want to ask my Polish friend Jan to come and spend Christmas with us. Will that be all right? His father and mother died last year, he can go home for Christmas, and he has no friend in England except the Browns. He is a nice boy. I know you all like him, and I feel sure he will enjoy Christmas with us. It is very short notice, but you are always pleased, I know, if we bring our friends home. however, I have not yet invited him, as I thought it was better to ask you first.
