Researchers Jose Cordova and Erich Astudillo have discovered a new molecule(分子) that kills the bacteria Streptococcus Mutans, long known to be responsible for breaking down sugars in food in the mouth, which damages tooth leading to decay(腐烂). The new molecule they call “Keep 32” has been found to kill the bacteria.
The two have applied for a patent(专利) on their discovery and have also begun a marketing strategy aimed at both oral care products and food products. They say either product, if left in the mouth for just 60 seconds ,will kill all the harmful bacteria in the mouth and keep them at bay for several hours. If the new molecule passes health and safety tests, the two believe products using their new molecule should be on the market in as little as a year and a half. They expect the market for such a product to reach $300 million in just the first year.
The two have been working together since 2005 using money from the Founder Institute and say the aim is to approve the process for creating the molecule they’ve discovered for big companies like Procter & Gamble, Colgate even candy companies such as Hershey’s. In interviews, Astudillo has suggested that the two researchers are already heavily into discussion with several companies, some of which are interested in buying the patent once it is approved.
Over the years many products have come on the scene with announcement of reducing tooth decay and even the loss of teeth, but other than the introduction of fluoride(氟化物) into drinking water, not much progress has been made. If the announcement made by this new team proves true however, it could foresee a mark in saving the world of tooth decay as well as helping to improve the health for millions of people as tooth decay has been linked to many other health problems throughout the body including heart attacks.The underlined word “them” in Para. 2 refers to _________.
| A．oral care products | B．food products |
| C．new molecules | D．the harmful bacteria |
The phrase “come on the scene” in Para. 4 is closest in meaning to __________.
| A．performed | B．occurred |
| C．existed | D．arrived |
What has been a way to reduce tooth decay and even the loss of teeth over the years?
| A．Using the molecule “Keep 32”. |
| B．Killing the bacteria Mutans. |
| C．Introducing fluoride into drinking water. |
| D．Cooperating with some big companies. |
This passage mainly tells us that ___________.
| A．many health problems are closely connected to tooth decay |
| B．the discovery of a new molecule will greatly benefit health care |
| C．two researchers are discussing their patent with companies |
| D．researchers discover a molecule that can kill tooth decay-causing bacteria |
阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。
Celebrities(名人) have become a powerful influence on some people because of their social position and their economic situation.
First，some people admire and imitate stars because they allow themselves to be influenced by the media. Television，radio，and magazines invade(侵扰) the lives of audience with a variety of shows，information，and publications about stars and their lives. For instance，Britney Spears has become the target of paparazzi(狗仔队)．In May，Britney appeared at the front page of the most popular magazines revealing that she married her best friend in Vegas，Nevada. Media also invade stars' lives because reporters know they get high profits from readers who buy and follow their favorite artists' news.
Second，some mad audience imitate their celebrities for their lack of confidence. Some people who are shy and lack personality may find that imitating others will cause a good impression. For instance，my cousin Jenny，who lacks a social life because of her introverted(内向的) personality，believes that acting and dressing like Jennifer Lopez will make her popular in high school.
Finally，several fans of stars imitate them because of peer(同龄人) pressure. Since my niece's girlfriends formed an Antonio Banderas' fan club，she had also joined the group. Although she wasn't a huge fan of his，now she collects most of Banderas' possessions. In fact，when I asked Arianna，my niece，why she was part of Banderas' fan club，she replied with a doubtful tone that she did not wish to be rejected by the other teens.
In conclusion，it is true that celebrities play spectacular roles in their performances in Hollywood，which entertains many people all over the world；however，modern celebrities influence the audience to the point where their fans admire and try to imitate their lives.What does the passage mainly tell us?

阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。
A public high school in the rural town of Boonsboro，Maryland，offers a special program recently. Top students in the ninth and tenth grades can attend single－sex classes for math，science，English and social studies.
The aim is to help teenagers keep their mind on their work by keeping males and females apart. Rebecca Brown chooses the students for what Boonsboro High School calls the Academy. “What we really want to do is take that top group of kids and take them to the very highest level they can achieve here，so that they’re prepared for college，” she said. They need high marks and test scores and strong teacher recommendations. They also need to be involved in activities.
Michael Bair has been at Boonsboro High School for twenty years and directs the Academy. His ninth－grade English class for boys centers on books that he believes boys find interesting. “The novels they’re reading now，are very manly novels. They’re novels that deal with the arrogance(傲慢)of man and the pride of man.” One of those books，for example，is “The Call of the Wild” by Jack London. This classic story tells of a dog stolen from his home and sold to work as a sled dog in Canada’s Klondike Gold Rush.
On this day，the students are working in small groups. Vincent and Logan explain why they're drawing pictures that relate to the story. Vincent said，“The main character，Buck，gets abducted(绑架) and they send him off to the Yukon in a train.So I’m drawing part of the story where he’s in the train. It gets you to visualize the setting of the story and gets you to think more about what’s going on in the story，the important events of the story.”“ Instead of just doing work sheets about it，this is a lot more fun，” Logan added happily.
Morgan Van Fleet likes being in the Academy. She says boys and girls act differently when they are together in a classroom. “To me，it almost seems like it’s hindering(妨碍)? your chances at developing yourself because you’re more focused on ‘Oh，I wish they’d shut up. Oh，what do they think of me？’ instead of focusing on what’s the homework or what’s going on in this class，what’s the lesson.”

阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。
I suppose that the most basic and powerful way to connect to another person is to listen. Just listen. Perhaps the most important thing we ever give each other is our attention. And especially if it’s given from the heart. When people are talking, there’s no need to do anything but receive them. Listen to what they’re saying. Care about it. Most times caring about it is even more important than understanding it. Most of us don’t value ourselves or our love enough to know this. It has taken me a long time to believe in the power of simple saying “I’m so sorry,” when someone is in pain.
One of my patients told me that when she tried to tell her story people often interrupted to tell her that they once had something just like that happening to them. Her pain became a story about them. Eventually, she stopped talking to most people. We connect through listening. When we interrupt what someone is saying to let them know that we understand, we move the focus of attention to ourselves. When we listen, they know we care.
I have even learned to respond to someone crying by just listening. In the old days I used to reach for the handkerchiefs, until I realized that passing a person a handkerchief may be just another way to shut him down, to take them out of their experience of sadness. Now I just listen. When they have cried all they need to cry, they find me there with them.
This simple thing has not been that easy to learn. It certainly went against everything I had been taught since I was very young. I thought people listened only because they were too shy to speak or did not know the answer. But now I know that a loving silence often has far more power to heal than the kindest words.What does the author value most in the communication with each other?
| A．Deep understanding. |
| B．Saying “I'm sorry”． |
| C．Attention from heart. |
| D．Doing nothing. |
The woman patient stopped telling her story to most people because ________.
| A．she didn't get enough respect from others |
| B．she was discouraged by being often interrupted |
| C．people often told her their own opinions |
| D．people couldn’t understand her sad situation |
If you hand a handkerchief to someone crying，you may ________.
| A．hurt his feelings |
| B．make him embarrassed |
| C．encourage him to continue to cry |
| D．stop him from letting out his sorrow |
It can be inferred from the passage that while communicating，________.
| A．listening is a perfect way to respond to others |
| B．people keep silent because they don't know the answer |
| C．keeping silent means being too shy to speak |
| D．it is easy to form the habit of listening silently |
Which of the following might be the author's opinion about communication?
| A．Keep silent. |
| B．Just listen. |
| C．Be careful. |
| D．Tell your own story. |

When I was 13，my bedroom walls were covered with posters of the Monkees and the Beatles.I wrote fan letters and daydreamed about meeting the objects of my affections.I begged my parents to attend every rock concert and watch every TV show featuring my favorite celebrities(名人)；my friends and I discussed for hours all the things we would say and do when we met our favorite movie stars and pop singers.I drove my mother crazy！But after a few years，my obsession(迷恋) with stars faded as I matured and gained the confidence to socialize with “real” boys.
In the 35 years since I was a teenager，celebrity worship(崇拜) has increased among teens due to the explosion of television celebrity gossip shows，and instant access to celebrity news on the Internet.It's no wonder that many teens are obsessed with stars when news programs often are filled with entertainment stories and the lives of celebrities.
Celebrity worship syndrome(综合征) is now considered a personality disorder.While it is normal for teenagers to follow the lives of their favorite stars，parents should try to monitor everything their child finds interesting.Parents should take action if they suspect a teen is too obsessed with celebrities and showing little interest in school or withdrawing from the family.When teens talk a lot about celebrities and view them as just means of entertainment，this is considered normal celebrity worship.However，when a teenager is obsessed with a star and often expresses a desire to have a close personal relationship with a celebrity or feels they have a special connection to a star，this may be the time for concern.Recent studies have shown that teens who develop an unhealthy obsession with celebrities often suffer from low selfconfidence and depression.Teens who are overly obsessed with stars often have damaged relationships with their parents.The first paragraph is intended to tell us ________.

阅读下列短文，从每题所给的四个选项(A、B、C和D)中选出最佳选项。
A
Greg Evans started to study film at Ryerson University，but had a change of heart and switched to social work at George Brown College in the second year.Yet the college recognized only one of Evans' generalinterest credits(学分) from Ryerson，and also made him take English all over again although he had passed it at university.
“So I spent time and money taking a course I had already taken before，”complained Evans.“The system really needs to change.”Evans was part of a chorus of Ontario students on Monday cheering a new $73.7 million fiveyear plan to help students switch from college to university，and from university to college.
After years of urging from students，the Ontario government set up a new Credit Transfer Innovation Fund to help students move back and forth between the more handson courses of community college to the often broader academic focus of a university degree.“We hear horror stories about students who can't get recognition from one institution for a very similar course at another，and in one case I believe the same professor was teaching them both，” noted Milloy after announcing the new fund.
Individual colleges and universities have decided on nearly 500 joint deals to honour each other's credits in certain courses.Each school is required to set targets for more credittransfer agreements，and link these increases to provincial funding.
More than 4,000 college graduates transfer(转学) to university in Ontario every year－twice as many as eight years ago，noted Justin Fox，president of the College Student Alliance.Yet Ontario universities and colleges have been cautious about transferring credits，in part to avoid copying each other's courses，noted Bonnie Patterson，president of the Council of Ontario Universities，who welcomed the increased flexibility.What happened when Greg Evans switched to social work at George Brown College?
| A．He was considered to be unqualified for social work. |
| B．His previous credits were not all recognized. |

| A．get enough money to go to university. |
| B．switch between colleges and universities |
| C．get enough generalinterest credits |
| D．have a wise choice of courses |
According to Paragraph 3，Milloy believes ________.
| A．it is time that the system was changed |

| A．He is strongly against it. |
| B．He is very doubtful about it. |
| C．He thinks it is too flexible. |
| D．He supports it for its flexibility. |
