Making Peace with Your Parents

As a teen, you’re going through big changes physically and mentally. Your interests are expanding.   1   

Here is the challenge:Kids need to explore the world in new ways, and parents need to protect them from the dangers that all out in that world. These conflicts can easily set off fireworks in otherwise calm houses. Sometimes conflicts can’t be avoided. But by paying attention to the building blocks of successful relationships, you can work towards making home a happy and healthy place for you and your parents.

    For instance, try to find a time to talk when your parents are all not angry, tired, distracted, or hungry. A good time to talk is when you’re all relaxed. Timing is everything. If the conversation begins to turn into an argument, you’d better calmly and coolly ask to stop the conversation—for now.   2  Listen to what your parents are saying, and repeat it back to them. This shows them that you’re listening.   3 

Respect is the building block of good communication. People who respect each other and care about each others’ feelings call disagree without things getting ugly.

      4  How do you build trust? Trust comes by actually doing what you say you’re going to do. Some teens find that doing fun activities with their parents can improve their relationships. Sometimes we forget that parents are more than rule-makers—they’re interesting people who like to watch movies. And go shopping—just like their teenagers!

    What do you do if you are trying your best, but your relationship with your parents continues to be rocky?   5  You can find supportive adults, such as a teacher or a coach, who can lend an ear.

    Remember you can only change your own behavior. Your parents are the only ones who can change theirs.

       A.It also gives them a chance to clear things up if you’re not on the same page.

      B.You can pick it up again when everyone’s more relaxed.

C.And then you’ll be able to accept what your parents say.

D.Faced with the challenge, children don’t know what to do.

E.You are more likely to get along with your parents and have more independence if your parents believe in you.

F.And your desire to take control of your own life is growing.

G.You may consider seeking outside help.

June 26, 2000 — the Human Genome(基因组) Project, a great $3 billion, 15-year task aimed at drawing the genetic(遗传的) map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging(延长) human life. But those communities and policy makers also are careful about the scientific door they are opening as the project uncovers the mysteries of life.

For the last few years, the genetic advances in the developing field of biotechnologyhave provides material for all kinds of work, but the developments of modern science in unlocking the secrets of the human genetic codehave opened a world of possibilities for human health, as well as for the popular imagination.

While European and Japanese researchers are making rapid progress in decoding(解码) human DNA, the leading organization for genetic research is in the United States, which began in 1990, is “unlocking the code” of the human body to learn how to defeat fatal(致命的)diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with terrible diseases as yet(迄今), and making progress toward separating the genes that show a sign of breast cancer or AIDS.

Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses.

1. Why did the scientists work hard at mapping the human genome?

A. Because the human genome can destroy many illnesses.

B. Because the human genome's completion can help them get rid of many diseases.

C. Because they wanted to be better known than others.

D. Because the human genome can provide a lot of chances of work.

2.Which country studied the genes most rapidly in the world?

A. Japan.           B. Germany.              C. The United States.       D. China.

3. Which of the following is NOT true?

A. If the genes can be found, scientists can study many new ways to cure illnesses.

B. The scientists have made great progress in connecting the genes with the cancers.

C. Many medical companies show great interest in drawing the human genome map.

D. The United States began the Genes Study early in the 19th century.

4.The author suggests that the Human Genome Project can cause _______.

A. the policy makers to feel very worried and careful

B. the scientists to work harder

C. many people to find work easily

Alaskan black bears hibernate for up to seven months a year, during which time they do not eat or drink, before waking up in virtually the same physical state they fell asleep in.

    Now experts hope to develop methods of putting humans into a similar state which could help astronauts survive long missions and lead to new ways of treating severely ill patients.

    While many studies have examined hibernation in mice and hedgehogs, little research has been done into the same condition in larger mammals such as bears.

    But new research conducted at the Institute of Arctic Biology at the University of Alaska monitored the animals' body temperature, heart rate and muscle movements while they slept.

    The research results showed that during a five-month hibernation the bears’ body temeratures varied between 30℃ and 36℃ in cycles that lasted between two and seven days—a pattern that was previously unknown in hibernating animals.

    The research project leader said, "If our research could help by showing how to reduce metabolic(新陈代谢的) rates and oxygen demands in human tissues, one could possibly save severely ill patients. We simply need to know how to turn things on and off to take advantage of the different levels of hibernation."

    Craig Heller, of Stanford University, who contributed to the study, added: "There has always been a thought that, if there is ever long-distance space travel, it would be good to be able to put people into a state of lower metabolism or a state of hibernation. That's almost science fiction but you can see the logical basis."

1.We know from the text that            .

    A.during winter Alaskan black bears sleep for more than half a year

    B.researchers have examined hibernation in humans

    C.experts have got no results from their research

    D.Craig Heller is a leader from the Institute of Arctic Biology

2.The best topic of the text should be                

.  A.The Latest Research Results

    B.New Methods of Putting Humans into Hibernation

    C.Alaskan Black Bears Hibernate

    D.Astronauts Could Hibernate Like Bears

3.According to the text, we can infer that          .

    A.many studies have examined hibernation in mice and bears as well

    B.humans' body temperatures vary between 30℃ and 36℃ while they sleep

    C.research into hibernation in animals may help deadly patients stay longer

    D.scientists have already take advantage of the different levels of hibernation in space missions

Mapping Your World

    Different forms of maps are appearing.They allow independent travelers to get local knowledge of places they are visiting, from the official to the unusual.Meanwhile, hi-tech developments are creating new ways for us to map the world.Here are two of our favorites:

Maps Mashups

1.According to the passage, which of the following is a characteristic of Green Maps?

    A.Introducing local attractions with icons

    B.Aiming at environmental protection

    C.Offering advice to independent travelers.

    D.Collecting icons worldwide for local maps.

2.Which of the following icons is most probably NOT used in Green Maps?

3.“Map Mashups” is named with the word “mashups” because      

A.it is produced by users all over the world B.it is a branch of Google Maps

C.it shares icons with Green Maps          D.it gathers various kinds of information

4.What do Green Maps and Map Mashups have in common?

    A.They are created by local people.

    B.They are environmentally friendly.

    C.Users can edit maps on the Internet.

    D.Users need to communicate with producers.
