Researchers in the United States have developed the first wirelessly controlled device that can supply a drug directly into the body. A small chip is implanted (植入) under the skin. It contains the medicine, which it releases at preset times. The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses. A company called Microchips began developing the device about fifteen years ago. Last month, the company released the results of its first successful tests in humans. The tests took place in Denmark with seven women with osteoporosis（骨质疏松症）.
Osteoporosis causes bones to become weak and break easily. The disorder is common among older people especially women. Many patients have to give themselves daily injection（注射）of medicine. One type of treatment requires injections for two years. The patients stop taking the medicine because of the pain and stress of the injections. As a result, only twenty-five percent of the patients will go through the entire twenty-four months of treatment.
The microchip is a few centimeters long. It has small sections and each section holds a single dose（单次剂量）of medicine. The device has to be programmed with the times to release the drug. Doctors will be able to reprogram the device from a computer or even a cell phone.
For osteoporosis, the physician will program the device, and the device has the ability to release a dose at a given time, every single day. For other diseases, where the physician may want to change the dosing schedule, they will have the ability to wirelessly reprogram that dosing schedule.
The seven women in the study were ages of sixty-five to seventy. The researchers say the implants were just as effective as daily injections. And they say the medicine amounts were more exact than patients often give themselves.
The best title for the passage should be ______.

A．A New Company Called Microchips

B．A New Way to Take Medicine Every Day

C．Good News for Women with Osteoporosis

D．Taking Medicine, with Microchip under Skin

What does the underlined word “released” in paragraph 1 mean?

A．Announced.

B．Planned.

C．Got rid of.

D．Caught hold of.

We can learn from Paragraph 2 that ______.

A．older people especially men easily develop steoporosis

B．bones’ becoming weak and breaking easily causes steoporosis

C．a quarter of the patients will go through the entire two years of treatment

D．pain and stress of the injections lead all patients to stop taking medicine

What advantages does the microchip have?
a. effective implants
b. less exact medicine amounts
c. purposely—changed dosing schedule
d. only one centimeter long and having small sections

Mozart was one of the greatest composers who ever lived. He was born in Salzburg,
Austria, in 1756. Even when he was very young, Mozart loved music. His father, who was the leader of an orchestra, was very happy that his son was so interested in music. When Mozart was three years old, he learned to play the harpsichord, which is a kind of piano. Mozart began to compose music at the age of five, and his father took him to play in front of the kings and queens of Europe.
At one concert, one of the violinists was missing from the orchestra. Mozart picked up a violin and played the music without a mistake. Mozart’s father and the other players in the orchestra were surprised. Mozart had never been taught to play the violin! Mozart continued travelling around Europe with his father, who was his teacher in everything. He composed many pieces for the piano, the violin, and later for full orchestra.
Mozart could write down a piece of music even if he had heard it only once. One day, he went to hear a group of people singing in a big church in Rome. The song was very special. The church leader said that people could sing the song only once a year, and only in his church. No one else was allowed to have the music. Mozart listened to the song. Although it was very difficult and long, Mozart went back home and wrote down the whole piece from memory. The head of the church heard about this, and instead of being angry with Mozart, he gave him a prize.
When Mozart grew up, people were not so interested in him. He worked as a teacher and pianist, but he did not make much money. In 1791, at the age of 35, he died. He was so poor that there was not enough money for him to have a proper grave. No one knows where he is buried.

Thanksgiving Day is a very special day for people in the United States. In that country they celebrate Thanksgiving Day on the fourth Thursday in November. Canadians also celebrate Thanksgiving Day, but they do it on the second Monday of October. In Britain, where the festival is called “ Harvest Festival”, people celebrate earlier in the year, in September.
A harvest is the fruit you take from the trees and the crops you take from the ground. In North America, Europe, and England, harvest time for most fruit and crops is in the special day of the year. They thank God for the good things that have happened during the year and for the good harvest they have had. People usually take small boxes of fruit, flowers, and vegetables to their churches to show their thanks.
The first thanksgiving service in North America took place on 4 December 1610 when 38 English people arrived in America to make their home in the new country. They held this service not to thank God for the harvest, but to thank God for their safe journey. The next year, many more English people arrived. They had a bad winter, but fortunately the harvest was good. They decided to celebrate with a big meal. They shot and killed small animals to eat and cooked everything outside on large fires. About 90 Indians also came to the meal. Everyone ate at tables outside their houses and played games together. The festival lasted three days.
A Thanksgiving Day celebration was held every year for a long time, but not always on the same day of the year. Then, in 1789, President George Washington named 26 November as the Day of Thanksgiving. Almost a hundred years later, President Abraham Lincoln changed the date, and said that the last Thursday in November should be Thanksgiving Day.
Nowadays, North Americans around the world get together with their families on this day to eat good food and have a happy time.
39. The story is about ____.
A. festivals B. an American festival
C. English people in America D. giving thanks for everything

Have you ever been at a meeting while someone was making a speech and realized suddenly that your mind was a million miles away? You probably felt sorry and made up your mind to pay attention and always have been told that daydreaming is a waste of time.
“On the contrary,” says L. Giambra, an expert in psychology, “daydreaming is quite necessary. Without it, the mind couldn’t get done all the thinking it has to do during a normal day. You can’t possibly do all your thinking with a conscious（有意识）mind. Instead, your unconscious mind is working out problems all the time. Daydreaming then may be one way that the unconscious and conscious states of mind have silent dialogues.”
Early experts in psychology paid no attention to the importance of daydreams or even considered them harmful. At one time daydreaming was thought to be a cause of some mental illnesses. They did not have a better understanding of daydreams until the late 1980s. Eric Klinger, a professor of psychology, is the writer of the book Daydreaming. Klinger says, “We know now that daydreaming is one of the main ways that we organize our lives, learn from our experiences, and plan for our futures. Daydreams really are a window on the things we fear and the things we long for in life.”
Daydreams are usually very simple and direct, quite unlike sleep dreams, which may be hard to understand. It’s easier to gain a deep understanding of your life by paying close attention to your daydreams than by trying to examine your sleep dreams carefully. Daydreams help you recognize the difficult situations in your life and find out a possible way of dealing with them.
Daydreams cannot be predicated（预料）. They move off in unexpected directions which may be creative and full of ideas. For many famous artists and scientists, daydreams were and are a main source of creative energy.
72．The writer of this passage considers daydreams         .
A．hard to understand B．important and helpful
C．harmful and unimportant D．the same as sleep dreams
73．The writer quoted（引用）L. Giambra and Eric Klinger to         .
A．point out the wrong ideas of early experts   B．list two different ideas
C．support his own idea                    D．report the latest research on daydreams
74．Which of the following is TRUE?
A．An unconscious mind can work all the problems out.
B．Daydreaming can give artists and scientists ideas for creation.
C．Professor Eric Klinger has a better idea than L. Giambra.
D．Early experts fully understood what daydreams were.
75．What is the main difference between daydreams and sleep dreams?
A．People have daydreams and sleep dreams at different times.
B．Daydreams are the result of unconscious mind while sleep dreams are that of conscious
mind.
C．Daydreams are more harmful. D．Daydreams are more helpful in solving problems.
