As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the
animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty?”
Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious. According to the passage, which of the following statements is true?
| A．People are curious in the same way. |
| B．People in different countries are interested in different things. |
| C．Men and women are curious about different things. |
| D．People of different ages are interested in different things |
Scientists who work with the biological sciences study____.
| A．the earth , the oceans and the sky |
| B．man-made things |
| C．plants and animals |
| D．ocean water |
When you run, your muscles need ____.

We can see how the product life cycle works by looking at the introduction of instant（速溶） coffee. When it was introduced, most people did not like it as well as "regular" coffee, and it took several years to gain general acceptance（introduction stage）.At one point, though, instant coffee grew rapidly in popularity, and many brands were introduced（stage of rapid growth）. After a while, people became attached to one brand and sales leveled off（stage of maturity）. Sales went into a slight decrease when freeze-dried coffees were introduced（stage of decline）.
The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies. The goal is to extend product life so that sales and profits do not drop. One strategy is called market modification. It means that marketing managers look for new users and market sections. Did you know, for example, that the backpacks that so many students carry today were originally designed for the soldiers？
Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens. A marketer may re-position the product to appeal to new market sections.
Another product extension strategy is called product modification. It involves changing product quality, features, or style to attract new users or more usage from present users. American auto manufacturers are using quality improvement as one way to regain world markets. Note, also, how auto manufacturers once changed styles eagerly from year to year to keep demand from falling.The first paragraph tells us that a new product is ________.
| A．not easily accepted by the public |
| B．often of poorer quality compared with old ones |
| C．often more expensive than old ones |
| D．usually introduced to satisfy different tastes |

| A．pleasing the young as well as the old |
| B．increasing usage among students |
| C．exploring new market sections |
| D．finding creative product designers |
In order to attract more consumers, U.S. auto makers are ________.
| A．modernizing product style |
| B．increasing product features |
| C．developing products of better quality |
| D．re-positioning their product in the market |
There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.
The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).
Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.
“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”
“How do you know this?” the science reporter of the Venus Evening Star asked.
“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.” “What does this mean as far as our flying saucer program is concerned?”
“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”
“Are there any other dangers that you discovered in your studies?”
“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”
“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”
“If all you say is true, won’t this set back the flying saucer program several years?”
“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.
| A．the feasibility of landing a satellite on Earth |
| B．the possibility of making a first-rate flying saucer |
| C．the feasibility of sending a Venus Being to Earth |

Federal regulators Wednesday approved (批准a plan to create a nationwide emergence alert（警报）system using text messages delivered to cell phones.
Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates（估计）more than 48billion text messages are sent each month.
The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission（FCC）with coming up with new ways to alert the public about emergencies.
"The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan.
Participation in the alert system by carriers -telecommunications companies is voluntary, but it has received solid support from the wireless industry.
The program would be optional for cell phone users. They also may not be charged for receiving alerts.
There would be three different types of messages, according to the rules.
The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction（绑架）emergencies, or so-called Amber Alerts.
The service could be in place by 2010.What is the purpose of the approved plan?
| A．To warn people of emergencies via messages. |
| B．To popularize the use of cell phones. |
| C．To estimate the monthly number of messages. |
| D．To promote the wireless industry. |
The improvement to the present system is in the charge of________.
A．CTIA B the Warning Alert and Response Network
C．FCC D．federal regulatorsAn alert message will NOT be sent if________.
| A．a child loses his way |
| B．a university shooting happens |
| C．a natural disaster happens |
| D．a terrorist attack occurs |
Which of the following would be the best title for the text?
| A．Cell Phone Alerts Protecting Students |
| B．Cell Phone Alerts by Wireless Industry |
| C．Cell Phone Alerts of National Disasters |
| D．Cell Phone Alerts Coming Soon |
“Dad! He took a book without paying!” I yelled .
My father looked surprised. Before the boy could say anything, his mother grabbed his arm and shook it. “Is it true? You stole? Tell me!”
Everyone was quiet. The boy began to cry, and he nodded his head. He pulled out the comic book (漫画书) from under his shirt.
