Some people like to get up early, but some do not. In fact, it is really good for us to get up early every day. Maybe those who don't like getting up early will not believe this, but it is true. Scientists made a survey in about one thousand people, and then they found that early rising(早起) people had less disease(疾病) than late rising people, and early rising people also look healthier than late rising people, and so on.

   So we may know early rising is helpful in more than one way. First, it helps to keep us healthy. We all need fresh(新鲜的) air. But air is never so fresh as early in the morning. Besides, it is useful to do morning exercises.

   Secondly, early rising helps us in our studies. In the morning we learn more quickly and find it easier to understand what we learn.

   Thirdly, early rising can give us a plan of our work for the day. We cannot work well without a good plan.

   Fourthly; early rising gives us enough time to get ready for our work, such as to wash our hands and faces and eat our breakfast.

   Late risers may find it difficult to form the habit(养成习惯) of early rising. They have to make an effort(努力) to do so. As the English proverb says, "Early to bed and early to rise makes a man healthy, wealthy(富裕的) and wise. "

People cannot reach an agreement on the use of science and technology. For example, will radiation from electronic equipment destroy the environment? Should medical scientists change gene structures to prevent genetic disease or to create “more perfect” human beings? While people are arguing about these and others, technology continues to influence our everyday lives—the home, health and education, entertainment and communication, and so on.

   Some people carry on active social lives with computers —their own or the ones in public places like cafes, social centers, libraries, and so on. Communicating with others in chat rooms,  computer users can get to know people they might never meet in traditional ways. With live online video connections, two people with cameras in their computers can see and talk to each other from separate places.

   With modern telephone technology, most people stopped writing lettters—especially personal letters and notes. But now, writing to communicate has returned in electronic form, or e-mail, which is a way of sending messages from one computer to another. For some computer users, the wish to communicate intelligently or creatively with others makes them want to write better.

   Computer technology has also made it possible to run a house electronically. From turning lights on and off to starting the coffee and cooking the hot meal, computers are taking care of people at home. Many modern machines have computer chips that allow their owners to program them. For instance, you can “instruct” a microwave oven how to cook a dish. Most entertainment equipment operates with computer technology too. Computers can even start cars automatically so that on cold winter mornings you can get into a warmed-up vehicle and drive off.

   Although much of the technology in our everyday lives has good effects, there are some uses that raise questions. For example, are interactive media ( i.e., a combination of television, telephone, and computer) going to control minds, cause people to forget about family life and personal relationships? What effects will the genentic engineering of food have on people’s health? High-tech medical treatments can make a person live a much longer life, but can they improve the health and happiness of human beings? Only time will tell, but, in the meantime, science and technology will continue to move forward.

D.The writer questioned high-tech medical treatments somehow.

4. What is the best title for the passage?

   A. Science and New Technology        B. Computers Change Our Lives

   C. Everyday Uses of Technology        D. Only Time Will Tell          

Algae(水藻) are very simple plants. They grow in fresh water or salty water. Seaweed is algae that grow in salty water. Seaweed is red or brown in color. The Japanese people use these plants from the sea in many ways. From it, they make a food called Kombu. Kombu is seaweed that has been dried, cooked and pressed together. Then it is dried again and cut into long pieces. The Japanese eat a lot of Kombu and like it very much.

   Japanese farmers often use seaweed as fertilizer. It makes their plants grow better. Many farmers also find seaweed makes a fine food for their animals.

   From seaweed the Japanese also get iodine(碘), which they sell to other countries. Iodine is used in many ways all over the world. It is used in making medicine. It is added to the salt we use at the table. Scientists even use one form of iodine to “seed clouds” when they want rain to fall.

1.Kombu is a kind of ____ according to the text.

A. plant      B. medicine          C. food        D. fertilizer

2.In the last sentence of the text, “seed clouds” means ____.

For years scientists have been arguing about whether nature or nurture (后天) decides what people will be like. Is it nature— what people are (41) with— that decides what they will be like? (42) is it nurture —what(43) to people when they are born —that decides what they will be like?
Scientists have been studying twins to (44) if they can find the answer, because twins start out with the (45) DNA. Sometimes twins don’t live together at birth and grow up in different (46) and different places— so the nature is the same for both, but the nurture is different.
When scientists (47) these twins in their later life, they some times find some surprising (48).
Jim Springer and Jim Lewis were adopted（收养）by two different families at birth. They first met each other again thirty-nine years (49) and discovered they had a lot in (50). Both had been (51) twice. Their first wives were both named Linda and their second wives were both named Betty!
Each twin had a son — one called his son James Alan and the (52) called his son James Alan, too. Their children each had a dog called “Toy”. They even arrived at their first (53) in the same color of car.
So far twin (54) seem to show that both nature and nurture are important. What we have from birth, and how and where we live help to build (55) we are.
