(C) I’ll Be Bach
1 Composer David Cope is the inventor of a computer program that writes original works of classical music. It took Cope 30 years to develop the software. Now most people can’t tell the difference between music by the famous German composer J. S. Bach (1685-1750) and the Bach-like compositions from Cope’s computer.
2 It all started in 1980 in the United States, when Cope was trying to write an opera. He was having trouble thinking of new melodies, so he wrote a computer program to create the melodies. At first this music was not easy to listen to. What did Cope do? He began to rethink how human beings compose music. He realized that composers,brains work like big databases. First, they take in all the music that they have ever heard. Then they take out the music that they dislike. Finally, they make new music from what is left. According to Cope, only the great composers are able to create the database accurately, remember it, and form new musical patterns from it.
3 Cope built a huge database of existing music. He began with hundreds of works by Bach. The software analyzed the data:it broke it down into smaller pieces and looked for patterns. It then combined the pieces into new patterns. Before long, the program could compose short Bach-like works. They weren’t good, but it was a start.
4 Cope knew he had more work to do-he had a whole opera to write. He continued to improve the software. Soon it could analyze more complex music. He also added many other composers, including his own work, to the database.
5 A few years later,Cope’s computer program, called “Emmy”,was ready to help him with his opera. The process required a lot of collaboration between the composer and Emmy. Cope listened to the computer’s musical ideas and used the ones that he liked. With Emmy, the opera took only two weeks to finish. It was called Cradle Falling, and it was a great success! Cope received some of the best reviews of his career, but no one knew exactly how he had composed the work.
6 Since that first opera, Emmy has written thousands of compositions. Cope still gives Emmy feedback on what he likes and doesn’t like of her music, but she is doing most of the hard work of composing these days!

Step Back in Time
Do you know that we live a lot longer now than the people who were born before us? One hundred years ago the average woman lived to be 45. But now, she can live until at least 80.
One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily.
But in order that we don't slip back into bad habits, let's have a look at what life was like 100 years ago.
Families had between 15 and 20 children, although many babies didn't live long.Children suffered from lots of diseases, especially tickets (佝偻病 ) and scurvy ( 坏血病) , which are both caused by bad diets. This is because many families were very poor and not able to feed their children well.
Really poor families who lived in crowded cities like London and Manchester often slept standing up,bending over a piece of string, because there was no room for them to lie down.
People didn't have fridges until the 1920s. They kept fresh food cold by storing it on windowsills (窗台板 ) , blocks of ice, or even burying it in the garden.
Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks ( 火柴杆) ( a job done by many children ) or working with your dad by now.
16. On average women lived longer than men 100 years ago.
A.Right
B.Wrong
C.Not mentioned
6、Why should anyone want to read abstracts of books by great authors when the real pleasure comes from reading the originals.
A.themes
B.insights
C.digests
D.leaflets

Stem Cell Therapy May Help Repair the Heart
According to scientists in the USA, stem cell therapy may one day be able to repair the hearts of people with heart failure.Researchers at Pittsburgh University School of Medicine examined 20 patients who had severe heart failure and were going to have surgery.
They injected stem cells into the parts of their hearts that were damaged. They then compared their hearts with those of people who had undergone surgery without having the stem cells injected into them ( they had also suffered from severe heart failure ) . The patients who had the stem cells injected had hearts that were able to pump ( 用泵抽运) more blood than the others.
According to Professor Robert Kormos, one of the researchers, these results could revolutionize heart treatment. Although previous studies had indicated that there might be a benefit, this is the first study that has actually proved that stem cell therapy can help the failing heart work better.
All the patients in this study had hearts that could not pump blood properly. The scientists measured their ejection fraction ( 射血分数 ) . It is a measure of heart performance; you measure how much blood is being pumped out by the left ventricle ( 心室) .
Healthy people's ejection fraction is about 55%. These patients had ejection fraction of under 35%. They all had by-pass surgery ( 搭桥手术) performed on them. Some of the patients had stem cells taken from their hip bones and injected into 25-30 sites in the damaged heart muscle. Six months later their ejection fraction rate was 46.1% while those who just had surgery but no stem cell injections averaged 37.2%.
Heart failure is a common problem all over the world.In the UK alone about 650,000 people suffer from heart failure every year. As the number of people suffering from heart failure increases in the word in general these findings are particularly significant.
Current treatments relieve the symptoms. This new stem cell therapy actually repairs the damaged muscle in the heart and has the potential of curing the disease.
The 20 patients had stem cell injections instead of surgery.
A.Right
B.Wrong
C.Not mentioned

What We Take from and Give to the Sea
