Does a drink a day keep heart attacks away? Over the past 20 years, numerous studies have found that moderate alcohol consumption, say, one or two beers, glasses of wine or cocktails daily helps to prevent coronary heart disease.Last week a report in the New England Journal of Medicine added strong new evidence in support of that theory.More important, the work provided the first solid indication of how alcohol works to protect the heart.
In the study, researchers from Boston’s Brigham and Women’s Hospital and Harvad Medical School compared the drinking habits of 340 men and women who had suffered recent heart attack with those of healthy people of the same age and sex.The scientists found that people who sip one to three drinks a day are about half as likely to suffer heart attacks as nondrinkers are.The apparent source of the protection: those who drank alcohol had higher blood levels of high density lipoproteins (脂蛋白), the so called good cholesterol (胆固醇), which is known to prevent heart disease.
As evidence has mounted (增长), some doctors have begun recommending a daily drink for patients of heart diseases.But most physicians are not ready to recommend a regular happy hour for everyone.The risks of teetotal ling (绝对戒酒) are nothing compared with the dangers of too much alcohol, including high blood pressure, strokes and liver troubles---not to mention violent behavior and traffic accident.Moreover, some studies suggest that even moderate drinking may increase the incidence of breast and colon cancer.Until there is evidence that the benefits of a daily dose(吸收剂量) of alcohol outweigh the risks, most people won’t be able to take a doctor’s prescription to the neighborhood bar or liquor store.
60.The report mentioned in the first paragraph indicates________.
A.the way in which alcohol can help the heart.
B.that a couple of cocktails daily can help stop heart problems
C.why alcoholic drinks are dangerous to one’s health
D.that reports on the advantages of alcohol were misled
61.Experiments showed that nondrinkers had___________.
A.larger amounts of good cholesterol   B.smaller amounts of good cholesterol
C.higher blood pressure              D.lower blood pressure
62.According to the passage, moderate drinking_______.
A.is recommended by most doctors for heart patients
B.should be allowed on prescription
C.is still not medically advisable
D.is not related to liver problems
63.The main theme of this passage is___________.
A.the change in recent drinking habits
B.the connection between cancer and alcohol
C.whether moderate drinkers outlive nondrinkers
D.whether alcohol may be good for one’s health

Actually we have known a lot of examples and meaningful words to support the fact that we should try our best to ease the bad impression of others. Just like the old saying goes, we should give a better assumption to the one than we think he was. But many of us always fail to do this.
Take the situation of my class for example. Right at the beginning of the first semester when we were freshmen we all showed great favor to each other. And when there was an activity that needed some people to join, we would be willing to attend whether it was interesting or not. And we were really like brothers and sisters, and our class was just like a family, a warm family. But now, I feel tired of those meaningless activities not only because of the boring activities themselves but also the cool response of our classmates.
I think the reasons why the passion of most classmates is so low may be as follows:
To start with, many of us take part in more than one organization, which will certainly make us tired. Also, in the study fields, many of us may find that our courses are sometimes difficult to understand or comprehend, especially the specialized subjects. Moreover, "history" teaches us that if one does not study hard, it is possible to fail in the exams. So it is a big and good excuse to say that "I do really want to attend, but I have a lot of horse work to do, so'"."
Last but not least, some people believe that some of our leaders should not be regarded as a leader, maybe I should say we, as leaders, lost the reputation, support and trust of yours. At least I am the warm-hearted one, although I cannot promise you that your advice will be adopted surely, at least I will spare no effort to "give" you the right to be heard, and to serve you.
Be active to show your talents and abilities and to create a better image of our class. Most important of all, work painstakingly for a better condition that we should have reached.
At the beginning of the first semester the students were_____ each other.

A.quite curious about B.active and kind to

About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
The passage is mainly about _____________.

A.color and its surprising effects.
B.women being luckier than men
C.danger caused by color blindness
D.color blindness

According to the passage, with the help of the “cones”, we can_______________.

A.tell different shapes B.see in a weak light
C.kill mosquitoes D.tell orange from yellow

Why do some people say it is safer to be driven by women?

A.Women are more careful.
B.There are fewer color-blind women
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.

Which of the statements about the color- blind is true?

A.Not all of them have the same problem in recognizing color.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.

Frank Woolworth was born in Rodman, New York., in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be farmer. He took a short business course, and went to work as a salesman in a large city.
Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品 ) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.
Soon afterwards, Woolworth opened his own store., selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.
By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always run his business according to strict rules, of which the most important was: “ THE CUSTOMER IS ALWAYS RIGHT.”

Have you ever been sad because of failure? Please remember, for quite often achieving what you set out do is not the most important thing.
A boy decided to dig a deep hole behind his house. As he was working, a couple of older boys stopped by to watch. “What are you doing?” asked one of the visitors. “I want to dig a hole all the way through the earth!” the boy answered excitedly. The older boys began to laugh, telling him that digging a hole all the way through the earth was impossible. After a while, the boy picked up a jar. He showed it to the visitors. It was full of all kinds of stones and insects. Then he said calmly and confidently, “Maybe I can’t finish digging all the way through the earth, but look at what I’ve found during this period!”
The boy’s goal was far too difficult, but it did cause him to go on. And that is what a goal is for-to cause us to move in the direction we have chosen, in other words, to cause us to keep working!
Not every goal will be fully achieved. Not every job will end up with a success. Not every dream will come true. But when you fall short of your aim, maybe you can say, “Yes, but look at what I’ve found along the way! There are so many wonderful things having come into my life because I tried to do something!” It is in the digging that life is lived. It is the unexpected joy on the journey that really makes sense.

A.A Boy Dug a Hole

I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled(贴标签) everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.
War broke out one evening. Kate came into the room. Soon, I heard her screaming, “Take your shoes away! Why under my bed!” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.
The room was filled with anger. We could not have stayed together for a single minute without a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled(爬) under her covers, weeping. Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart,
Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn’t noticed Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me. “Thanks.”
Kate and I stayed roommates for the rest of the year. We didn’t always agree, but we learned the key to living together: giving in, cleaning up and holding on.
