Nothing is more pleasing and romantic as flowers in the bedroom. Now, a new study says that the sweet smells of flowers in the bedroom can also lead to sweet dreams.
Researchers in Germany have carried out the study and have found that sleeping with flowers in the bedroom may encourage sweet dreams, a major finding they claim could help nightmare sufferers to and extent.
They came to the conclusion after an analysis of the sleep patterns of 15 female volunteers for a period of nearly 30 nights, a leading British newspaper reported on Monday.
The researchers pumped scents of rotten eggs, roses or no scent under their noses for nearly ten seconds while the women were in the Rapid Eye Movement period of sleep when a dream occurs.
The subjects were then woken up and asked to record their dreams. The smells had an effect on the emotions of the dreams but did not become part of the dream in that the women exposed to roses did not dream about roses the study found.
There was a correlation between the negative smells and negative emotional scores the sleepers reported from their dream.
According to the researchers, it’ll be interesting to study nightmare sufferers and if positive smells can actually influence the mood of their dreams as a form of treatment in the future.
The study has been presented at the 2008 American Academy of Otoblaryngology-Head and Neck Surgery Foundation Annual Meeting in Chicago.

A new study says one part of the human brain may become smaller as the result of a condition known as jet lag. Jet lag results from flying long distances in an airplane. Jet lag interferes with a person's normal times for sleeping and waking. People with jet lag may feel extremely tired for several days. They also may have problems thinking clearly and remembering.
Kwangwook Cho is a researcher at the University of Bristol in Britain. He reported the findings of his jet lag study in the publication Nature Neuroscience.
The study involved twenty young women who worked for international airlines. The women had served passengers on airplanes for five years. These flight attendants flew across many countries and at least seven time zones. In the study, the flight attendants had different amounts of time to recover from jet lag. Half the women spent five days or fewer in their home areas between long flights. The other half spent more than fourteen days in their home areas.
Mister Cho took some fluid from the women's mouths to measure levels of a hormone that increases during stress. He tested them to see if they could remember where black spots appeared on a computer screen. And he took pictures of their brains using magnetic resonance imaging. This is a way to measure the size of the brain's temporal lobes(顳葉).
It was found that the women who had less time between flights had smaller right temporal lobes. This area of the brain deals with recognizing and remembering what is seen. The same group performed worse and had slower reaction times on the visual memory test. And their saliva samples showed higher levels of stress hormones.
Mister Cho says he believes the brain needs at least ten days to recover after a long trip. He says airline workers told him their ability to remember got worse after working on planes for about four years. Other studies have shown that increased feelings of stress can cause a loss of cells in the part of the brain that controls memory.
Scientists say more tests are needed to study the effects of jet lag on the brain. They want to find out if too much jet lag could permanently affect memory.
72. According to the text, jet lag _____.
A. can cause difficulties in speaking
B. can make people feel tired for a few weeks
C. is the illness only found in people who work on the airplanes
D. can be caused by flying over several time zones in an airplane
73. It is inferred that more tests need to be done because _____.
A. the conclusion was questioned by many scientists
B. scientists fear that his research is not done properly
C. every scientific conclusion needs the support from many tests
D. the woman who were studied in the research were not healthy
74. Which of the following statements is TRUE about the research results?
A. Women who have a longer rest at home show better memory.
B. Women who fly in short time had smaller right temporal lobes.
C. Women who have longer flights failed the memory test.
D. Women who rest more than 14 days produced less hormones.
75. What is the subject discussed in the test?
A. The cause of jet lag.
B. A story of a group of flight attendance.
C. A research about the effects of jet lag on the brain.
D. The importance of having enough rest after long flights.

While many young celebrities, especially pretty women, are unwilling to talk about their humble origins, Lu Yan is never too shy to talk about her hometown a small village in northern Jiangxi Province. Surrounded by high mountains, silver stone mining is the major source of wealth in the town where she was born in 1981. When she goes home to visit, she has to take a train from the provincial capital Nanchang for more than an hour, then change to a bus for another hour and a half.  
Lu is the eldest of three siblings. "We broke the family planning policy, because village people always want a son," she said smiling. Lu wears clothes from big-name designers now, but when she was a child she often went several years without new clothes. "I grew tall so fast that my mother thought buying new clothes was wasteful," she said. She had no choice but to wear hand-me-downs from relatives. 
Lu still remembers clearly her first "made to order" clothing. She picked cotton for a whole summer vacation and earned 90 yuan (US$11). She spent 6 yuan (US$0.70) to take a bus to the county where she asked a tailor to make a coat according to a design in a magazine. "At that time, I thought it was a very modern design," she said. It meant more to her than all the haute couture(高級(jí)時(shí)裝設(shè)計(jì))she owned later.
When she graduated from middle school, the 16-year-old Lu was 1.78 metres high. She left for Nanchang to study accounting. "My parents thought the major would help me find a job," she said. She was self-conscious of her height and began walking hunched(拱背)over. "I always bowed. As I grew up, I started to know that my posture(姿勢(shì))was not good, so I attended a figure-building class," she said. Little did she know that it would lead her to a bright future.  
64. The underlined word “humble” in Paragraph One means_______.
A. rich         B. poor         C. bright          D. modern
65. What does Lu Yan mean by referring to her first "made to order" clothing?
A. Lu Yan made her coat to her own measure by herself.
B. She thought it was a very interesting..
C. She earned the money through her own hard work.
D. It meant a lot to her and her future.
66.Which of the following about Lu Yan isn’t mentioned in the passage? 
A. Age.        B. Height.      C. Hometown.          D. Salary.

On 27th February 2008, something very unusual happened in the UK; there was a rather large earthquake. It was the biggest earthquake in 25 years in the UK. There have been very small tremors in the past but they pale into insignificance compared to this one.
It was felt in a large area across the country too, from as far north as Edinburgh in Scotland to as far south as Plymouth on the south coast of England.
The epicenter of the earthquake was in a small town in Lincolnshire, which is an area about two and a half to three hours north of London by car. A magnitude of 5.2 was registered on the Richter scale.
There were lots of reports in the news from people who felt the earth move. One man said, "We had loads of vibrating and wall shaking and stuff, noise coming off the roof. I came outside – the chimney's on the floor!"
A collapsed chimney was the cause of what was probably the worst injury from the earthquake; a man broke his pelvis when the chimney fell on him.
Another man who spoke to the BBC described the moment the earthquake occurred, "Everything was shaking. As soon as it happened we all went outside and saw everyone else down the street, coming out and just realized it was an earthquake."
The huge rumble, which was felt by a lot of people, surprisingly caused very little structural damage to property.
Most British people would be surprised to learn that there are 200-300 earthquakes in Britain every year, but most of them are so small, they go unnoticed. The magnitude of this earthquake is fairly small in comparison to some other natural disasters that have made international news, but for the people affected, it certainly came as quite a surprise.
60. Before this earthquake _______.
A. there was no signs of any shakings at all.
B. people did not feel anything unusual.
C. many people realized there would be a bigger one to come.
D. some small quakes were only too small to be ignored.
61. From this passage we know ______ is in the south of Great Britain.
A. Lincolnshire                      B. Edinburgh
C. Plymouth                         D. Scotland
62. This earthquake  _____.
A. hardly caused any damages to the people’s belongings..                
B. brought down many buildings in England.
C. scared many people to death.
D. made the world greatly surprised.
63. After reading this passage we can infer_______.
A. people in England faced the earthquake bravely.
B. this earthquake seemed to be felt all over Great Britain.

第一節(jié):閱讀下列短文,從每題所給的四個(gè)選項(xiàng)A、B、C、D中選出最佳選項(xiàng)。
Agricultural scientists in the United States have put a copy of a human gene into pigs, sheep and rabbits. They report that the gene seems to be working in some of the animals. The gene that the scientists are using controls the production of human growth hormone(荷爾蒙), a chemical necessary for growth.
They are using the human gene because it has been more closely studied than any other growth gene. The scientists hope their work will someday result in food animals that grow faster and larger or produce more milk or eggs. The research is being done by scientists at the University of Pennsylvania, the University of Washington and the United States Department of Agriculture. The scientists put copies of human growth hormone into the fertilized (受精的) eggs of the female animals. When baby animals were born from the eggs, the scientists looked for evidence that the human gene had become part of the animal’s genetic material. They examined almost 200 baby pigs and found the gene in 20 of them. They found it in 28 of more than 200 rabbits, but it was in only one of 73 baby sheep. The scientists said they found the human growth chemical produced by the gene in some of the animals.
It is too soon to know if the animals will pass the human growth gene into their young, proving that the gene has become part of their genetic material. Similar research with mice two years ago produced a new kind of mouse that is two times larger than normal. The scientists hope the same thing will happen with farm animals. They say their research will permit other gene transplants that can give animals defense against diseases, or let them live in very hot or very cold places. American farmers already use chemical hormones to increase the size of cattle and the amount of milk they produce. But they have to put the hormones into the cows. If the gene transplants are fully successful, the cow’s body will produce growth hormone.
56. How many kinds of animals have scientists put copies of human gene into?
A. 2      B. 3    C. 4         D. 5 
57. Why did the scientists do such a research?
A. To prove that the human gene had become part of the animal’s genetic material.
B. To expect food animals that grow faster and larger or produce more milk or eggs.
C. To find the human growth chemical produced by the gene in some of the  animals.
D. To follow a similar research with mice carried out two years ago.
58. The underlined word “them” refers to ______.
A. the baby pigs    B. baby animals     C. the scientists     D. the baby sheep
59. What can we learn about the research with mice?
A. A new kind of mouse was produced, which is defensive against diseases.
B. The hormones from the mice were then put into the cows.
C. A new kind of mouse was produced, which is twice larger than normal.
D. Scientists found that the mice can live in very hot or very cold places.
