Searching for life on other planets

For more than thirty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages, as well as messages on spaceships traveling through space, on the chance that someone may receive such messages.

Scientists are using powerful radio telescopes to “l(fā)isten” to signals from about 1,000 stars, all within 100 light years of Earth. In addition, they will scan the entire sky to listen for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight million channels at a time. Scientists are looking for any signal that stands out from the background noise.

Of the 200 billion stars in the Milky Way galaxy, scientists find that five percent are like our sun. Perhaps half of them have a planet like Earth. Such a planet would be a reasonable distance from the star for temperatures to be right for life. Based on the planets in our galaxy, most scientists agree that one or more of these planets may support some life.

However, many scientists wonder whether intelligent life exists on other planets. Some believe that thirty years of searching without any intelligible messages shows that no one is out there. They say that intelligence comparable to ours is unlikely.

Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family is only about five billion years old, our galaxy is about 20 billion years old. In that time some scientists think it is likely that civilizations much more advanced than ours have developed. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

A. have sent up spaceships to other planets

B. have sent radio and television messages to outer space

C. are listening to the radio messages all the year round

   C. we didn’t send messages on spaceships

   D. none of the other stars is right for life

Some scientists think there might be more advanced civilizations on other planets because _____.

A. some planets support more advanced civilizations

B. some civilizations have sent us signals we can’t recognize

C. the evolution of intelligence on other planets is unlike ours

D. some planets in our galaxy are much older than the earth

How do apology languages work? Have you ever tried to apologize, only to be refused? It may be that you were offering a partial apology in a “l(fā)anguage” , that was foreign to your listener．The five languages of apology include:

Apology Language 1: “I am sorry.”

List the hurtful effects of your action．Not “I am sorry if …”, but “I am sorry that…”．You might ask if they want to add any points that you have not recognized.

Apology Language 2:“I was wrong.”

     Name your mistake and accept fault．Note that it is easier to say “You are right” than “ I am wrong”, but the latter carries more weight.

Apology Language 3: “ What can I do to make it right?”

     How are you now? How shall I make amends(彌補(bǔ)) to you? How can I restore your confidence that I love you— even though I was so hurtful to you?

Apology Language 4: “I’ll try not to do that again.”

     Engage in problem-solving．Don’t make excuses for yourself such as, “Well, my day was just so…” Instead, offer what you will change to prevent yourself from putting them in the same bad situation again．

Apology Language 5: “Will you please forgive me?”

      Be patient in seeking forgiveness．They may need some time or greater clarification of your input from Apology Languages 1-4.

      Finally, your apology may not be accepted, but at least you know that you have been faithful in offering a sincere olive branch of peace.

A research by the National Center for Health Statistics is seen as an important confirmation of the“Hispanic mortality paradox（西班牙裔死亡率悖論）.”

On average，Hispanics outlive whites by 2.5 years and blacks by 7.7 years. Their life expectancy at birth in 2006 was 80.6 years，compared with 78.1 for whites，72.9 for blacks and 77.7 years for the total population.

The report shows that the Hispanic population has higher life expectancy at birth and at almost every age despite a socioeconomic status lower than that of whites.“Mortality is very correlated with income，education and health care access，”says Elizabeth Arias，author of the report.“You would expect the Hispanic population would have higher mortality，”in line with the black population.

The Hispanic paradox has been documented for more than two decades，but this is the first time the government has had enough data to issue national numbers. Researchers are struggling to explain why Hispanics live longer.

“We don’t know，”says David Hayes-Bautista，director of the Center for the Study of Latino Health and Culture at UCLA’s David Geffen School of Medicine.“We thought it was a problem in the data，but we can pretty much say this is real.”

Potential factors:

·Culture and lifestyle.  Support from extended family and lower rates of smoking and drinking.Latino groups in particular have very strong family and social ties.

·Migration.  The“healthy migrant effect”argues that healthy people are more likely to emigrate. And when immigrants become ill，they might return home and die there.

    Solving the puzzle may help the nation deal with health care issues because Hispanics use health services less—they make fewer doctors visits and spend less time in hospitals，Hayes-Bautista says.“It’s clearly something in the Latino culture，”he says.

In 2006，Hispanics’life expectancy is           years longer than the average of the total population.

    A. 2.5                 B. 7.7               C. 2.9              D. 80.6

What does the underlined word“outlive”in the second paragraph probably mean？

A. To live longer than…                      B. To live shorter than…

C. To die out.                              D. To expect to live.

What is the main idea of paragraph three？

A. Hispanics were born better than whites.

B. Morality is closely related with health care access.

C. Whites should have longer life expectancy.

D. Even experts can’t explain the phenomenon.

What is Mr.Hayes-Bautista’s opinion about the paradox？

A. He supports there is a problem with the data.

B. He intends to trust the cultural factor.

C. He believes in the“healthy migrant effect”.

D. He thinks health care the most important factor.

Which of the following inferences is true according to the passage？

A. Black people suffer the lowest social status in America.

B. Hispanics might have healthier ways of life.

C. Only healthy people can immigrate into America.

D. White people don’t have strong family ties.
