An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding. When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives. The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone. The setup of the product does not need to be hooked up to a car’s speedometer. In fact, it is entirely portable. It will also work with newer phones and PDAs that have built-in GPS receivers. If a driver exceeds the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product. He told Live Science that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding. There is also a potentially controversial future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said. “The system even has the capability to record speeding violations, so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney. What’s the purpose of the new product?
| A．To inform us of the new car system. | B．To introduce some improvement in cars. |
| C．To limit certain drivers to safe driving. | D．To popularize the built-in car system. |
The second paragraph mainly talks about .
| A．the project of the built-in product | B．why the system becomes popular |
| C．the functions of GPS in cars | D．how the product is programmed |
Which of the following is true of Speed Alert according to Michael Paine?
| A．Most of the traffic deaths can be avoided. | B．Speeding violations can be easily found out. |
| C．The system will excite some teenage drivers. | D．The product will not be available for adults. |
What can be the best title of the passage?
| A．Speed Alert and Its Future Use. | B．Progress in Car-making Science. |
| C．Warning for Adventurous Drivers. | D．New In-Car Device against Speeding. |
Why do men live a shorter life than women? The latest research indicates that men’s hearts going into a rapid decline when they reach middle age could be the cause.
The research of ageing on the heart has shown that women’s longevity may be linked to the fact that their hearts do not lose much pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 20 and 70 years of age,” said the head of the study, Samantha of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells which make it beat. Between the ages of 20 and 70, one-third of those cells die and are not replaced in men ,” said Samantha. “This is part of the ageing process.”
What amazes scientists is that the female heart suffers very little loss of these cells. A healthy 70-year-old woman’s heart could work almost as perfectly as a 20-year-old one’s.
“This gender （性别）difference might give the reason why men live shorter than women,”said Samantha. They studied over 250 healthy men and women between the ages of 17 and 80, who are mainly healthy persons so as to reduce the influence of disease. “The team has yet to think about why ageing suffers a greater loss on the male heart,” said Samantha.
But there is also good news -- men can enjoy the health of their hearts with regular exercise. Samantha stressed that women should also take regular exercise to stop their leg muscles getting weaker as they age.The underlined word “longevity” in the second paragraph means “________”.
| A．health | B．long life | C．ageing | D．effect |
The text mainly talks about ________.
| A．men’s heart cells | B．women’s ageing process |
| C．the gender difference | D．hearts and long life |
According to the text, the UK scientists have known that ________.
| A．men have fewer cells than women when they are born |
| B．women can produce the cells that make the heart beat |
| C．the female heart suffers less loss of the cells with age |
| D．women will never suffer the loss of pumping power with age |
If you want to live a long life, you should ________.
| A．enable your heart to beat much faster |
| B．think about the reason for ageing |
| C．take regular exercise to keep your heart healthy |
| D．stop your cells from being lost |
October 15th is Global Handwashing Day. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap.
Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
Global Handwashing Day is the idea of the Public-private Partnership for handwashing with soap. The goal, they say, is to create a culture of handwashing with soap. The organizers say all soaps are equally effective at removing disease-causing germs （细菌）. They say the correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Then, wash well under running water. Finally, dry your hands with a clean cloth.
The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases the chances that people will wash again.
It also says that washing hands with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea （痢疾）, which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half.What does the author intend to tell us in the passage?
| A．To keep healthy by washing hands. | B．To wash hands with soap. |
| C．To take action to wash hands. | D．To wash hands often. |
Which of the following is the right way to wash hands?
a. Washing hands well.b. Covering hands with soap.
c. Drying hands.d. Rubbing hands with soap.
e. Wetting hands.
| A．a--c--b--e--d | B．e--d--a--b--c |
| C．a--c--b--d--e | D．e--b--d--a--c |
Which fact can’t explain why soap is important?
| A．It gives people a longer handwashing time. |
| B．It helps to remove a lot of germs from hands. |
| C．It attracts people to do more handwashing. |
| D．It gets all people into the habit of washing hands. |
According to the last paragraph, diarrhea is a disease that ________.
| A．kills half of the kids in the developing countries a year |

Several times my daughter had telephoned to say, “Mum, you must come and see the daffodils （水仙花）before they are over.” I wanted to go, but it was a two-hour drive from Lake Arrowhead. “I will go next Tuesday,” I promised, a little unwillingly, on her third call.
The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn’s house and hugged and greeted my grandchildren, I said, “Forget the daffodils, Carolyn! The road is invisible （看不见的）in the cloud and fog, and there is nothing in the world except you and these children that I want to see!”
My daughter smiled calmly and said, “We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience.”
After about twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read “Daffodil Garden”.
We got out of the car and each took a child’s hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up and gasped. Before me lay the most beautiful sight! There were five acres of flowers! “But who has done this?” I asked Carolyn. “It’s just one woman,” Carolyn answered. “That’s her home,” Carolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio （庭院）, we saw a poster. “Answers to the Questions I Know You Are Asking” was the headline.
The first answer was a simple one. “50,000 bulbs （鳞茎）,” it read. The second answer was, “One at a time, by one woman.” The third answer was, “Began in 1958.”
I thought of this woman whom I had never met, who, more than fifty years before, had begun -- one bulb at a time -- to bring the beauty and joy to the mountain top.The author didn’t go to see the daffodils at first because _________.
| A．she was not interested in them |
| B．they were growing on the mountain top |
| C．the weather was not good enough |
| D．it was not easy for her to drive there |
What do we know about the woman living in the A-frame house?
| A．She must be out of mind. |
| B．She acted as a gardener there. |
| C．It took her great determination to grow the daffodils. |
| D．She was poor and made her living by selling daffodils. |
What could the author probably learn from this experience?
| A．Nothing is too difficult if you put your heart into it. |
| B．We must put the interests of others above our own. |
| C．We can change the world by growing flowers. |
| D．It’s never too late to learn. |
What would be the best title for the passage?
| A．An Unforgettable Experience. | B．Beautiful Daffodils. |
| C．One Bulb at a Time. | D．I Love Daffodils. |
How can you find out what is going on inside a person’s
body without opening the patient’s body up? Regular X rays can show a lot. CAT scans can show even more. They can g
ive a complete view of body organs.
What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient’s body.
Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed.
A CAT scanner, however, uses a group of X rays to give a cross-sectional（横截面）view of a specific part of the body. A fine group of X rays is scann
ed across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear “photos” of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can “s
top the action”, giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient.
Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don’t cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays.
CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives.What is NOT true of a CAT scan?
| A．It is safer than regular X rays. |
| B．It makes use of computer techniques. |
| C．It can stop the action of an organ for a short time. |
| D．It gives clear pictures of active, moving body parts. |
The underlined words “a foreign object”（Para 3）most probably refer to.
| A．a badly injured part inside the body |
| B．a new thing that is unknown to the doctor |
| C．a strange organ that has grown in the body |
| D．an object that gets inside the body by chance |
What is the special use of the latest CAT scanners?
| A．It provides clear photos of moving organs. |
| B．It can take 3-dimension（三维）pictures of inside organs. |
| C．It won’t cause serious skin burns, cancer or other damage to the body. |
| D．It helps to find out what is going on inside a person’s body without opening it up. |
We can infer from this passage that.
| A．patients in front of CAT may suffer from a bit of radiation |
| B．doctors need no opening-up of the body with CAT scanners |
| C．CAT scanners are more expensive than regular X-ray machines |
| D．CAT scanners can take photos of either the whole body or a part of it |
The best title of this passage might be .
| A．the Newest Medical Invention |
| B．New X-ray Machine to Save Lives |
| C．How to Avoid the Damage of X Rays |
| D．Advantages and Disadvantages of CAT Scanners |
