We have saved as a final set of emotions the two most important emotions pertaining to other people: love and its opposite, hate. Love can be seen everywhere. Yet surprisingly, love has been the subject of less scientific research than other emotions, such as anger and fear. The reason for this may be twofold. First, love is a very complex emotion, difficult to describe and measure. Secondly, unlike many extreme emotions, extreme love is generally not a problem; thus less medical attention has been paid to it.

What is love? This is a complex question and requires a complex answer. Love is an enduring, strong, positive attraction and feeling for another person or thing. But it is more than this. It also involves feelings of caring, protection, excitement, and tenderness. When two people are in love, they feel drawn to one another; they greatly enjoy each other's company; and they may be sexually attracted to one another.

Sometimes it is easier to think in term of different kinds of love: “puppy” love, romantic love, brotherly love, and so forth. Though they differ in some respects, they share one important characteristic: a strong positive feeling toward another.

Our feeling toward other people are often complex. We may love someone and, at the same time, be angry with him. Or we may love someone, even though we are jealous of him. We might even love someone and, at the same time, hate him for some specific reason. Hate is a strong negative emotion toward someone, and is due to anger, jealousy, or some other factor. Like love, hate can be a very strong emotion. It can also be very dangerous. The question is often asked, “Is it bad to hate?” The best answer is probably “sometimes yes and sometimes no.” Usually hate does not help us; it makes us feel unhappy and makes us do things that may hurt others. However, sometimes it may be necessary to hate and hurt someone in order to protect loved ones.

　For more than twenty 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 on spaceships traveling through space, on the chance that someone may be receptive to such messages.

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

　　Of the 200 billion stars in the Milky Way galaxy（银河星系）, 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 the evolution（进化）of life. Based on the inhabitable（that can be lived in）planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.

　　However, many scientists wonder whether intelligent（有智力的）life exists on other planets. Some believe that twenty years of searching without any intelligible messages shows that no one is out there. They say that the evolution of 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 civilization（文明）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.

According to the passage, how many planets in our galaxy might be inhabitable?

　　A. 5 billion．　　　　　　　　　　 B. 10 billion.

　　C. 15 billion.　　　　　　　　　　　D. 200 billion

The first paragraph in this passage is mainly about ________ .

　　A. how scientists are looking for signs of life on other planets

　　B. why scientists are looking for signs of life on other planets

　　C. where scientists are looking for signs of life on other planets

　　D. when scientists are looking for signs of life on other planets

The underlined word “monitor” in the passage means“ ________ ”.

　　A. find　　　　　　　　　　　　　B. follow

　　C. check　　　　　　　　　　　　 D. form

Which of these statements is true based on the information in the passage?

　　A. The earth is one of the oldest planets in our galaxy.

　　B. Most scientists believe that there is intelligent life on other planets.

　　C. Scientists are trying different ways to find signs of life on other planets.

D. Scientists don’t believe that there might be life on other planets.

Simply by analyzing a drop of blood, a doctor will be able to diagnose a birth defect or even cancer when it is in the early stage; using new technology, a material lighter but much stronger than steel can be produced.
These may sound like dreams at present. But the dreams may soon come true as research findings in laboratories are being turned into products more rapidly in the new century, according to experts participating in the fourth Asia-Pacific Economic Cooperation (APEC) Technomart, a technology exhibition and trade fair in Suzhou.　　
"Most people think nano-technology（纳米技术）is too far-fetched to be real. But in fact nano-technology has been applied in a wide range of fields, such as medicine. It is coming into our daily life," said Cheng Jiachong from a Hong Kong-based nano-technology firm.
Nano-technology based on the nanometer, the unit of which is a billionth of a meter, enables scientists to have new concepts of disease diagnosis and treatment on a molecular（分子）and atomic scale, Cheng said.　　
By using nanometer particles, a doctor can separate the fetus cells（胚胎细胞）from the blood of a pregnant woman to see if the development of the fetus is normal. This method is also being used in the early diagnosis of cancer and heart disease, he said.　　
One of the most significant impacts of nano-technology is at the bio-inorganic materials interface, according to Greg Tegart, executive advisor of the APEC Center for Technology Foresight.　　
"By combining enzymes（酶）and silicon chips we can produce biosensors. These could be implanted in humans or animals to monitor health and to deliver corrective doses（剂量）of drugs," he told the participants a technology forum during the exhibition.　　
"Nano-technology could affect the production of nearly every man-made object, from automobiles, tires and computer circuits（电路）, to advanced medicines and tissue replacement, and lead to the invention of objects yet to be imagined," said David Minns, a special advisor to the National Research Council of Canada.　　
It has been shown that carbon nano-tubes are ten times as strong as steel, with one sixth of the weight, and nano-scale systems have the potential to make supersonic transport cost- effective and to increase computer efficiency by millions of times, he said.
The experts agreed that the APEC technology exhibition and trade fair provided many chances for exchanges of innovative ideas and products.
【小题1】Realization of the dreams mentioned in the first paragraph will mainly base on ________.
