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 |

Thank you for listening.
●Ms Tan, you’ve referred to your new novel as your eighth book.
That’s because it took me six or seven attempts at a second novel before I started and completed this one.
●Why do you think you had so many false starts?
I would say that my reasons were wrong. I was trying to prove that I wasn’t just a mother-daughter storyteller, or I was trying to prove that I didn’t just have to write about things that were strictly Chinese or Chinese-American. Those were never the right reasons for writing those early stories. And I could never come up with other better reasons for continuing them.
●What kept you going on this book?
This book was different because it was based on my mother’s real life. The reason for writing it became more personal and emotional. After The Joy Luck Club came out, my mother was always explaining to people that she wasn’t any of the mothers in that book. And at one point she said to me, “Next book tells my true story.” And then she started telling me things I never knew before. She also told me many, many stories, because my mother doesn’t generalize(笼统地表达). The book really grew out of that.
●Have you ever visited China?
Yes. I’ve been there twice: about three years ago and then again last November, both times with my mother and my husband.
●Was it difficult to understand the Chinese-American dialect(方言) without sounding like a parody(拙劣的模仿)?
No, because it’s the language I’ve heard all my life from my mother. She speaks English as it’s direct translation from Chinese. But it’s more than that. Her language also has more imagery than English.
●Can you think of an example?
Somebody might say to me, “Don’t work so hard. You’ll kill yourself.” My mother will say to me，“Why do you press all your brains out on this page for someone else？” So it’s very vivid. That’s the way she talks.
●Have many readers told you that the Chinese mother in your book reminded them of the typical Jewish (有癖好的) mother?
Many people have told me that. I think the mother-daughter relationship is very intense(紧张) in both cases. Culturally there is an acceptance that mothers have the power to tell their children, especially their daughters, how to conduct their lives --- not simply up until the time they are 18, but for the rest of their lives. However, when children grow up in a different culture from their parents’，they tend to keep more secrets from their parents. The children think, “They just wouldn’t understand that I had to do this.” And that can really create a gap, and it can grow as the number of secrets grows.Based on the questions in this interview, what do you think Ms Tan’ s profession is?
| A．A journalist. | B．A story-writer. | C．An interviewer. | D．An interviewee. |
What’ s TRUE about Tan’ s second book?
| A．It’ s about her real life in America. |
| B．The name of the book is The Joy Luck Club. |
| C．It is the result of many times of carefull thought. |
| D．It includes many works of her mother. |
Which question is NOT answered in the interview?
| A．How does she think of her mother’ s language? |
| B．How many books does she plan to write? |
| C．When did she visit China? |
| D．How is generation gap created? |
We can infer that________.
| A．Tan’ s mother is a good storyteller |
| B．Tan plans to write another book about her mother |
| C．Tan plans to return to China |
| D．Tan’ s mother is hard to communicate with because of personality |
The last paragraph mainly talks about________.
| A．how to keep secrets from parents |
| B．how to deal with the mother-daughter relationship |
| C．how to conduct the lives |
| D．how the generation gap comes about |

I went into Harrods in London (a huge department store I am sure you have heard of) to buy some Minton china plates for a wedding anniversary which was to be a group gift from friends to other friends in Geneva.
Having only 30 minutes between meeting. I whizzed there in a taxi from the office and battled through the milling people on the 2nd day of the sales on the ground floor up to the 5th to the china department. There was a man standing there who was obviously a sales person who I rushed up to and asked if he had this particular china in stock and if it would take long to wrap, etc. He was amazing. He got the plates in seconds, wrapped them up and asked me if I wanted a store card, to which I replied no, because I lived in Switzerland, to which he replied asking if, as I lived abroad, would like a tax rebate form(退税表). After that he showed me what to do, produced a map of the store and told me where I should go for the formalities(程序). That was fabulous! I thanked him and said what wonderful service he had given me. I even asked if he gave this to everyone, to which he answered: “I’m just doing what is required at Harrods”. With that, a tall man in a gray suit approached me and offered his hand to shake mine saying, “Can I introduce myself? I am the Chief Executive of Harrods and what an interesting conversation I have just heard…” He had been wandering through the store (as you should do as a hands-on CEO) and had overheard me thanking this salesman, whose face, I can hardly describe, was frozen in a mixture of delight awe and astonishment!
