These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.
"Most people think nano-technology(纳米技术)is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.
Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular(分子)and atomic scale, Cheng said.
By using nanometer particles, a doctor can separate the fetus cells(胚胎细胞)from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.
One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.
"By combining enzymes(酶)and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses(剂量)of drugs," he told the participants a technology forum during the exhibition.
"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits(电路), to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.
It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.
The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.

For example, imagine that you and your friends are arguing about who are the most popular music or movie stars, you can decide the argument by writing the names in the Googlefight boxes. Let’s say that you are arguing about Jackie Chan and Jet Li. You will quickly discover that Jet Li is mentioned 16 million times on Google pages, whereas Jackie Chan is mentioned a mere 12 million times! In this unscientific way, you can claim victory for one Star over another.
But teachers have come up with ways of using Googlefight which are much more useful from an academic point of view, particularly when it comes to studying languages. You can, for example, find out the frequency of two words with the same meaning, and deduce (推断) from the answers which one is more common. For example, let’s take the words “buy” and “purchase”, which mean the same thing (although “buy” is only a verb and “purchase” is both a verb and a noun). It is immediately clear from Googlefight that “buy” is much more commonly used, with a massive three and a half billion hits, compared to only one billion occurrences for the more formal word.
But the real value of Googlefight to the language learner is in determining which is the more common of two phrases. For example, “raining cats and dogs” is an old-fashioned English expression about the weather. Do English speakers still use it? Or are they more likely to say “pouring down”? Googlefight suggests the latter. “Pouring down” has 898,000 Google hits, whereas “raining cats and dogs” only has 326,000.
With phrases, it’s important to remember that you need to use quote marks to make the search more accurate. For example, if you type in the similar phrases “look after” and “take care of “ without quote marks, the second phrase seems to be more common, but with quote marks, the result is reversed.
小题1:What is Googlefight?
A.A fight between two people on Google. |
B.A way to make sure you win an argument. |
C.A website showing how many hits two different things have. |
D.A list of all the websites on Google. |
A.there are a lot of words on Googlefight |
B.it can tell them which of the two words with the same meaning appears more often |
C.some words mean the same thing |
D.common words have a billion hits |
A.Make sure they mean be same thing. |
B.Make sure they are different. |
C.Remember to put quote marks round the phrase. |
D.Don’t put quote marks round the phrase. |
A.Googlefight is effective to determine the more common of two phrases. |
B.Googlefight is a scientific way to decide an argument. |
C.Quote marks can make the search more accurate. |
D.Googlefight is invaluable to help win arguments. |
The bluefin tuna can live for 30 years, grow to three metres in length and weigh as much as 700kg. A good one can fetch as much as £ 52,000 in the Tokyo fish markets. “In my lifetime, we’ve brought this big fish to the doorstep of death in the western Atlantic Ocean,” said Barbara Block of Stanford University in California. “The electronic way of tracks provides the best scientific information we’ve ever had to manage these tuna and we must, as an international community, start to act actively to make sure of the future of this fish. ”
Scientists have repeatedly said that the harvest of the seas cannot be as good as before. There are fewer and fewer fish in around Newfoundland, North Sea and Iceland, so fishermen have pushed further offshore in search of deep ocean fish. Tuna—in the Mediterranean and Japan—have been under increasing pressure for years. The International Commission on the Conservation of Atlantic Tuna has tried to manage the fish since 1969.There are two populations: a western one that has dropped by 80% in the past 30 years, and a larger, eastern population. Although catches are controlled by 3,000 tons a year in the western fishery, and 32,000 in the east, no one knew whether the limits worked.
So Professor Block and her team placed tracks on hundreds of the fish and tracked them to depths of more than 900 metres and on journeys of thousands of miles, measuring the movement, body and water temperatures. “There are two ways to save the Atlantic bluefin tuna—protect them in their production grounds and in their feeding grounds,” Prof. Block said. “This will need immediate action in both the central Atlantic, to reduce the loss of the big fish while hunting, and in the Gulf of Mexico and Mediterranean, where tuna produce as separate populations. ”
小题1: The bluefin tuna in this passage mainly refers to the one _______.
A.in the Atlantic | B.in the Pacific |
C.in the Gulf of Mexico | D.in the Mediterranean |
A.The bluefin tuna is a kind of large and heavy fish. |
B.The number of the bluefin tuna in the sea is getting smaller and smaller. |
C.Scientists are worried about the future of the tuna. |
D.Scientists think that the harvest of the seas will remain good. |
A.finding a new way to protect them |
B.controlling the catches of them |
C.reducing the population to eat them |
D.protecting them in their production and feeding grounds |
A.tell people a new way has been found to save the bluefin tuna |
B.call for action to save the bluefin tuna |
C.warn people not to eat tuna sandwiches anymore |
D.help scientists to find a new way to save the bluefin tuna |
Away from home, eating is more than just a way to keep your stomach full.It is a language all its own, and no words can say, "Glad to meet you ...glad to be doing business with you ..." quite like sharing a meal offered by your host.
Clearly, mealtime is not the time for you to say, "Thanks, but no thanks." Acceptance of the food on your plate means acceptance of host, country, and company.So, no matter how difficult it may be to swallow, swallow.Or, as one experienced traveler says, "Travel with a cast-iron stomach and eat everything everywhere."
Often, the food offered represents proudly your host country"s eating culture.What would Ataiericans think of a French person who refused to take a bite of homemade apple pie or sirloin? Our discomfort comes not so much from the thing itself; it comes from our umamiliarity with it.After all, an oyster has remarkably the same look as a sheep"s eye; and a first look at a lobster would remind almost anybody of a creature from a science fiction movie, not something you dip in butter and eat.By the way, in Saudi Arabia sheep"s eyes are a famous dish and in parts of China it"s bear"s paw soup.
Can you refuse such food without being rude? Most experienced business travelers say no, at least not before taking at least a few bites.It helps, though, to slice any item very thin.This way, you minimize the taste and the reminder of where it came from.Or, " Swallow it quickly, " as one traveler recommends."I still can"t tell you what sheep"s eyeballs taste like." As for dealing with taste, the old line that "it tastes just like chicken" is often thankfully true.Even when the "it" is really rat or snake.
Another useful piece of advice is not knowing what you are eating.What"s for dinner? Don"t ask. Avoid glancing into the kitchen or looking at English-language menus.Your host will be pleased that you are eating the food he offers, and who knows? Maybe it really is chicken in that soup.

A.introduce unfamiliar food |
B.share the writer"s personal experiences |
C.suggest ways to overcome a cultural barrier |

C.lack of information about it | D.the unfamiliar atmosphere |
A.an American may feel comfortable with sirloin |
B.one should refuse strange food after a few bites |

A lazy Susan may also be a part of a kitchen cabinet. One may spin the lazy Susan in order to find certain goods stored in it. From the outside, a lazy Susan appears to be two cabinets. When one of these cabinets is pushed, however, both doors move and the lazy Susan is revealed inside.
Whether the lazy Susan is on a tabletop or within a cabinet, it can be made of a variety of materials. Most commonly, a lazy Susan is made of either plastic, wood or glass. Some people believe that Thomas Jefferson invented the lazy Susan, though it was referred to as a dumb waiter(上菜升降架) at that time. It is said that Jefferson invented the lazy Susan because his daughter complained she was always served last at table and, as a result, never found herself full when leaving the table. Others believe that Thomas Edison was the inventor, as he is believed to have invented the turntable for his phonograph(留声机), which later developed into the lazy Susan.
Regardless of who invented it, it wasn’t until 1917 that the term lazy Susan was created in an advertisement for the invention. In Britain, however, the term dumb waiter is still used rather than the term lazy Susan. The reason for the name lazy Susan remains a mystery. One theory is that it was named after either Jefferson’s or Edison’s daughter, both of whom were named Susan.
小题1: According to the passage, a lazy Susan _____.
A.is a person who serves food at table |
B.is a waitress who helps move dinner tables |
C.is an additional round table in a dining room |
D.is a turntable that passes food around the table |
A.On a tabletop, it is convenient for people to have dinner. |
B.Within a cupboard, it is easy for people to see what is inside. |
C.The turntable was invented in 1917. |
D.It can be made of many kinds of materials. |
A.Because she was too lazy. |
B.Because she was the youngest. |
C.Because the table was too tall for her. |
D.Because the table couldn’t move food for her. |
A.the lazy Susan was invented earlier than the phonograph |
B.Susan was the name of Jefferson’s and Edison’s daughter |
C.Jefferson and Edison invented the lazy Susan at the same time |
D.When people talk about a lazy waitress they use the term “Susan” |
A.What is a lazy Susan? |
B.When was the lazy Susan created? |
C.Why do inventions come from the daily life? |
D.How was “dumb waiter” replaced by “lazy Susan”? |
A new book called Battle Hymn of the Tiger Mother by Amy Chua has caused a debate about cultural differences in parenting. In Chinese culture, the tiger represents strength and power. In the book, Ms. Chua writes about how she demanded excellence from her daughters. She said that she had a clear list of what her daughters, Sophia and Louisa, were not permitted to do, such as attending a sleepover, having a play date, watching TV or playing computer games and getting any grade less than an A.
Many people have criticized Amy Chua. Some say her parenting methods were abusive(辱骂的). She even admits that her husband, who is not Chinese, sometimes objected to her parenting style. But she says that it was the way her parents raised her and her three sisters.
Ms. Chua makes fun of her own extreme style of parenting. She says she eased some of the pressure after her younger daughter rebelled and shouted, “I hate my life! I hate you!”
Ms. Chua says she decided to retreat when it seemed like there was a risk that she might lose her daughters. But she also says American parents often have low expectations of their children’s abilities. “One of the biggest differences I see between Western and Chinese parents is that Chinese parents assume strength rather than fragility(脆弱),” she said.
“The beginning of this intense discussion has to do with what it means to be a successful parent and what it means to be a successful child,” said Stacy Debroff, who has written four books about parenting.
Ms. Debroff says Amy Chua’s parenting style is not limited to Chinese families. She says it represents a traditional way of parenting among immigrants(移民) seeking a better future for their children.
But she also sees a risk. When children have no time to be social or to follow their own interests, they might not develop other skills that they need to succeed in life. Stacey Debroff advises parents to develop their own styles of parenting and not just repeat the way they were raised.
小题1:Amy Chua has been criticized mainly because ____.
A.she looks up to boys and down on girls |
B.she has already abused her right as a parent |
C.she hasn’t raised her children like her own parents |
D.she has fought with her children several times |
A.Uneducated. | B.Cruel. | C.Strict. | D.Strong. |
A.Amy Chua’s parenting style should be banned(禁止) in China |
B.Amy Chua’s should stop to adopt American parenting styles |
C.Amy Chua’s parenting style should be adjusted if possible |
D.There isn’t any advantages in Amy Chua’s style |
A.Give in. | B.Pass away. | C.Cry out. | D.Go ahead. |
A.Some books on studying styles. |
B.The disadvantage of Chinese parenting styles |
C.Differences between western and eastern parenting styles |
D.The comparison between American and Chinese parenting styles |
