Mrs. Luth Li was a Chinese woman living in Singapore. She named her baby girl Patsy Li. This name in Chinese means "white plum blossom". When Patsy Li was six years old, the Japanese attacked Singapore. Mrs. Li and Patsy Li escaped on a ship which was sunk. Mrs. Li placed Patsy Li on a bit of floating wreckage. Later Mrs. Li was saved, but the little girl could not be found.
Many months after, four thousand miles away, a group of United States Marines found a little Chinese girl. No one could tell how she had got there. She refused to talk or give her name. The captain who spoke Chinese named her Patsy Lee because he thought she looked like a white plum blossom.
When the New York Times told about the finding of "Patsy Lee", Mrs. Li’s sister saw the news and wrote to her sister about it. Could Patsy Lee be the lost child Patsy Li The mother made the long voyage to find out. The little "white plum blossom" was indeed her own Pasty Li.

When the Japanese attacked Singapore, Patsy Li was （） old.

A:six weeks B:six months C:six years D:sixteen years

In America, every student in his or her second year of high school is required to take a class in driver’s education.
The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver’s side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over.
After a student has passed the driver’s education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), he must take his driver’s test. The person must pass all three tests in order to be given a driver’s license. If the person does well in his or her driver’s education class, he or she will pass the test with flying colors and get a driver’s license.
We can infer that the students are required to ______in their whole driving practice.

A:go out driving for twelve times B:spend at least six hours driving C:drive for two hour blocks of time D:get half an hour driving

For example, those that had learned the maze six weeks after the injection had three times as much "activity" in their stained cells as those mice that learned the maze eight weeks after injection, when the stained cells were fully mature. Cells examined at less than six weeks’ old at the time of learning did not show as much activity as at six weeks, however. According to Frankland, this suggests that when neurons reach six weeks of age they are specifically recruited to form the brain networks that support new memories.
According to Fankland, the example shows that neurons in mice’s brains are specially recmited When

A:they are six weeks old. B:they are eight weeks old. C:they are between six and eight weeks old. D:they are less than six weeks ol

Effects of Exercise on Elderly Diabetics(糖尿病人)
Most older people with so-called type II diabetes(糖尿病) could stop taking insulin(胰岛素) if they would do brisk exercise for 30 minutes just there times a week , according to new medical research results reported in a Copenhagen newspaper, Results from tests conducted on diabetics at the Copenhagen central hospital Rigshospitalet’s Center for Muscle Research showed that physical exercise can boost the body’s ability to make use of insulin by 30 per cent. This is equal to the effect most elderly diabetics get from their insulin medication(药物治疗) today.
Researchers had a group of non-diabetic men and a group of men with type II diabetes, all more than 60 years of age, exercise on bicycles six times a week for three months. After the three months the doctors measured how much sugar the test subjects’ muscles could make use of as a measure for how well their insulin worked.
Associate Professor Dr Flemming Dela of the Muscle Research Center said the tests demonstrated that the exercising diabetics had made as good use of insulin as the healthy non-diabetic persons. "This means that the insulin works just as well for both group. Physical exercise cannot cure people of diabetes, but it can eliminate almost all their symptoms. At the same time it can put off the point at which they have to begin taking insulin," Dela said.
Insulin is a hormone produced by the pancreas(胰腺) , controlling sugar in the body and is used against diabetes.
Dela said that to achieve the desired effect diabetics need only exercise to the point where they begin to sweat, but that the activity has to be maintained since it wears off after five days without sufficient exercise.
Most diabetics realize that they have to watch their diet while remaining unaware of the importance of exercise, Dela added.
The exercise that the researchers tried on their test subjects was

A:cycling six times a week for three months. B:walking briskly for thirty minutes three times a week. C:swimming twice a day. D:running once a day.

There are thousands of volcanoes (火山) all over the world. What makes volcanoes What happens
The inside of the earth is very hot. Because it is very, very hot, the rock has melted like ice. It has become liquid, like water. It is always boiling, like water in a kettle. If you have seen a kettle boiling, you know that the steam and boiling water try to get out. The very hot melted rock inside the earth also tries to get out. Usually it cannot because the outside of the earth is too thick and strong.
But in some places the outside of the earth is thin and weak. Sometimes a crack appears. The hot melted rock, which we call "lava" (熔岩), pushes out through the crack and bursts through. Steam and gas shoot up into the air and the hot melted lava pours out. Big pieces of rock may be thrown high into the air.
After a while the volcano becomes quiet again. The melted lava becomes hard. Later the same thing happens again and again. Each time more hot lava pours out on top of the cold lava and then becomes hard. In this way a kind of mountain is built up, with a hole down the middle. Perhaps the volcano will then be quiet. Perhaps it will start again hundreds of years later.
Vesuvius is the name of a very famous volcano in Italy. It first came to life many, many years ago. It was quiet for hundreds of years. Then in the year 79 it suddenly burst. A great cloud of smoke shot up into the sky with great burning rocks. Hot lava poured down its sides. About 3,000 people were killed.
This has happened again many times since that year. Sometimes no damage was caused, or only little damage. But there was serious damage in the years 472, 1631, 1794, 1861, 1872 and 1906. You can see that a volcano can stay alive for many years. There was also serious damage in 1914 but there has not been any since that year.
According to the passage, Vesuvius has caused serious damage ______.

A:six times B:seven times C:eight times D:nine times
