There are some kinds of detectives who do not wear a uniform, like Hausman, solve endless mysteries every year. There is, for example, the dust detective. Tiny bits of dust stick to your clothes, your fingernails, your hair, or your shoes. They catch in your nose and in your ears. They tell where you have been and what you have done lately. The dust detective often helps catch a criminal by proving that he has been on the scene of the crime（罪案）.
Then there is the wood detective. By studying a piece of wood he can tell what kind of tree the piece of wood came from. He can tell where it was grown, and how old it is. He can even tell you what the weather was like at a certain place the year Columbus landed in America. The growth rings on a tree tell him.
64．According to the selection, by studying a piece of wood, a wood detective can tell you________.
A．what the weather was like the year Columbus landed in America.
B．what the weather was like last year in the mountain
C．what the weather was like last month in your hometown
D．what kind of tree the piece of wood came from
65．What does the underlined word “they”(para. 1) mean?
A．Your clothes B．Your finger-nail
C．Tiny bits of dust D．Your shoes
The flying car has been talked about for many years, but now it appears to become a reality.
An international company has built a two-seater plane that, at the touch of a button, transforms into a car perfectly suitable for driving on public roads. It takes 15 seconds to switch between flying and driving. With its wings fully open and the propeller(螺旋桨) spinning, it can take off from any airfield.
Flying cars are quicker than traditional ones, and they can run on ordinary fuel. Another big advantage is that they are cool, like something you would see in an action film. At the moment, however, the flying car’s wheels are illegal to leave the ground. That is not because of technical reasons or problems with the design. It is because the various road and aircraft authorities simply cannot agree on whether it is a car or a plane.
Nevertheless the company hopes to produce and deliver its first flying car soon. The company already has orders for 40 of them. The majority potential customers are older and some are retired. There have even been orders from some people who have no pilot’s license.
The flying car will cost around $ 200,000. “For an airplane, that’s a very reasonable price, but for a car, it’s quite expensive,” explains Alan. “But it just is not possible to make a $ 10,000 flying car yet.”
This latest means of transport will not become a mass-market item in the near future, but in the long term it has the potential to change the way you travel. It will become no more expensive than driving your car on the motorway. Travel time could be reduced by more than half.
So the next time you are told to fasten your seat belt, it may be to prepare for take-off.

In 1947 a group of famous people from the art world headed by an Austrian conductor decided to hold an international festival of music, dance and theatre in Edinburgh. The idea was to reunite Europe after the Second World War.
It quickly attracted famous names such as Alec Guinness, Richard Button, Dame Margot Fonteyn and Marlene Dietrich as well as the big symphony orchestras(交响乐团). It became fixed event every August and now attracts 400,000 people yearly.
At the Same time, the “Fringe” appeared as a challenge to the official festival. Eight theatre groups turned up uninvited in1947, in the belief that everyone should have the right to perform, and they did so in a public house disused for years.
Soon, groups of students firstly from Edinburgh University, and later from the universities of Oxford and Cambridge, Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre by little-known writers of plays in small church halls to the people of Edinburgh.
Today the “Fringe”, once less recognized, has far outgrown the festival with around 1,500 performances of theatre, music and dance on every one of the 21 days it lasts. And yet as early as 1959, with only 19 theatre groups performing, some said it was getting too big.
A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the number rises to 150 during August itself. In 2004 there were 200 places housing 1,695 shows by over 600 different groups from 50 different countries. More than 1.25 million tickets were sold.

Who Owns the Moon?
Within the next ten years, the US, China, Israel, and a crowd of private companies plan to set up camp on the moon. So if and when they plant a flag, does that give them property rights?
A NASA working group hosted a discussion this week to ask: Who owns the moon? The answer, of course, is no use. The Outer Space Treaty, the international law signed by more than 100 countries, states that the moon and other celestial bodies(天体) are the province of all mankind. No doubt that would annoy all of the people throughout the ages, like monks from the Middle Ages, who have tried to claim the moon was theirs.
But ownership is different from property rights. People who rent apartments, for example, don’t own where they live, but they still hold rights. So with all of the upcoming missions(派遣团) to visit the moon and beyond, space industry thought leaders are seriously asking themselves how to deal with a potential land rush.
“This is a very relevant discussion right now. We’ve got this wave of new lunar missions from around the world,” said William Marshall, a scientist in the small-spacecraft office at NASA, but who spoke this week at an event hosted by NASA’s Co Lab, a collaborative(协力的) public-private working group. He was peaking from his personal interest and not on behalf of the agency.
To be sure, the United States aims to send astronauts back to the moon by as early as 2015, in a mission that would include a long-term settlement. China and Israel, among others, are also working on lunar projects. And for the first time, several private groups are building spacecraft to land on the moon in an attempt to win millions of dollars in the Google Lunar X Prize. Some participants say that they plan to gain some property rights in the mission.
In the passage the writer seems to be worrying that .
| A．the US will live on the moon forever |
| B．the moon will not be able to hold all mankind |
| C．the potential land rush will become more and more frequent |
| D．no one can answer the question “Who owns the moon?” |
The “Google Lunar X Prize” aims to .
| A．encourage private groups to land on the moon |
| B．help NASA host a discussion about land rush on the moon |
| C．help some developing countries complete their lunar projects |
| D．reward some countries or private groups which haven’t stepped on the moon |
The underlined word “that” in the first paragraph refers to .
| A．the Outer Space Treaty | B．if and when they plant a flag |
| C．the NASA working group | D．monks from the Middle Ages |
What is the main idea of the last paragraph?
| A．The US astronauts will live on the moon for a longer time. |
| B．Many countries and private groups plan to go to the moon. |
| C．Why some private groups wish to land on the moon. |
| D．It is easy to gain some property rights on the moon. |
Michelle Obama, Kate Moss and Samantha Cameron are three of the most stylish﹙时髦的﹚ women on the planet because they have their daughters rather than their style. A new research has shown that women with daughters tend to be more stylish than mothers of sons; a fact partly because of the style advice their daughters offer as they get older.
78 percent of women over the age of 50 say they would be more than happy to let their daughters choose a complete outfit﹙全套衣装﹚ for them. However, just five percent of women say they would turn to their sons for style advice, while 28 percent believe that mothers of boys are less fashionable than women with girls.
“Women who don’t have daughters become less interested in style as they grow older but having a daughter may keep alive her interest in looking great,” comments psychologist Honey Langcaster-James. “And, because of their close relationship, they also have a source of support and encouragement when it comes to their style decisions.”
More than a quarter of women believe that Mums who have sons are less fashion-conscious than Mums with daughters. The most common reasons for this are that daughters are more critical, offer good advice and inspiration, and add an element of competition to look the best while sons don’t seem to care and aren’t as strict as daughters.
Interestingly, although mothers tend to rely on their daughters’ style tips, their confidence isn’t reciprocated﹙互换﹚, with 40 percent of women between the age of 19 and 34 saying they wouldn’t allow their mothers to shop for them as what their mothers would choose for them would not be as good as they expected.
And although they might not appreciate the fashion advice, the research, which was conducted by online retailer Gray & Osbourn, showed that daughters do still need their mothers with 71 percent saying they chat to their female parent every day.
“In short, the research shows just how important relationships are between mothers and daughters,” added Langcaster-James, “and just how much women appreciate an honest and trustworthy opinion.”
The opening paragraph is mainly to show .
| A．girls influence their mothers’ style decision |
| B．women with children are often less stylish |
| C．mothers like to follow their children’s advice |
| D．boys are actually better advisors than girls |
Which of the following may Langcaster-James agree with?
| A．Daughters usually love their mothers more than sons do. |
| B．It’s hard for boys to get along well with their mothers. |
| C．Mothers without daughters show less interest in style. |
| D．Girls are more independent than boys in some ways. |
It can be inferred from the passage that girls .
| A．show more interest in science than boys. |
| B．care more about what their mothers wear |
| C．can help a lot to solve family problems |
| D．are good at encouraging other people |
By saying “their confidence isn’t reciprocated” in Paragraph 5, the author means that .
| A．some women don’t like to choose clothes for their mothers |
| B．some women aren’t sure what to wear when attending a party |
| C．some women often show no confidence in themselves |
| D．some women would not like to follow their mothers’ style advice |
What does the author mainly tell us in the passage?
| A．It confuses many parents how to talk with their kids. |
| B．Daughters prefer to talk with their mums instead of dads. |
| C．It is important for parents to respect their children’s choice. |
| D．Mothers of girls are more fashionable than those of boys |
Children in the United States eat too much pizza that some researchers now argue the food should join the ranks of sugary drinks and fast food for the harm they do to health．
In a new study, the researchers found that pizza is a large source of calories, saturated fat(饱和脂肪)and salt in children’s diets．Children should not eat more than two slices of pizza for a meal．and should pair that with salad, rather than with another high-calorie food，the researchers concluded．
“Parents should aim to control pizza consumption(消费), particularly as a snack where it was shown to have a very adverse impact on children, and they should put their pizza dollars toward healthier brands．” said Lisa Powel, director of the Illinois Prevention Research Center．
Pizza has become a matter of focus in recent years for researchers who look at the meals children eat, rather than the nutrients within them．Studies have found pizza is among the greatest sources of calories for children．
“Since pizza remains a common part of children’s diet, we need to make ‘healthy’ pizza．”Powel said．To make pizza healthier, food producers should reduce its saturated fat and salt, and increase its whole grain content，she said．
Whether or not pizza is harmful enough to be picked out as an unhealthy food, the study attracts attention to a larger issue with the modern American lifestyle, said Alexis Tindall, who was not involved in the flow research．Many foods arc eaten too frequently and in large sizes．said Tindall．To solve the problem, people don’t have to give up eating pizza, but instead, they can eat smaller and healthier pizza，she said．
“Make it at home, instead of ordering it out where you don’t have any control over how it’s made．”Tindall said. “When we make it at home, we can choose healthier ingredients，increase the vegetables．reduce fat, and put in less cheese．Pizza doesn’t have to be just pepperoni(意大利辣香肠)and cheese．”
According to the research．children shouldn’t eat ．
| A．more than two slices of pizza in a day |
| B．two slices of pizza for a meal |
| C．more pizza with French fries |
| D．pizza along with salad |
Powel suggests healthier pizza should be made ．
| A．with less salt | B．with more ingredients |
| C．in smaller sizes | D．at home |
The last sentence of the passage implies that pepperoni and cheese ．
| A．are not necessary ingredients of pizza |
| B．should be reduced by adding healthier ingredients． |
| C．should all be replaced with healthier ingredient． |
| D．are not the only healthy ingredients of pizza |
What is the best title for the passage?
| A．Pizza—a real junk food! |
| B．How to prepare better meals for your kids? |
| C．Bring in healthier pizza for Americans |
| D．Discover the harm of eating pizza |
