Electronic books have changed the way many people read for 15 . Now online textbooks are changing the way some students learn and some teachers teach.
More than 16 students go to the public schools in Fairfax County, Virginia, outside Washington. Last year, the school system used digital books in fifteen schools. This school year, middle schools and high schools changed 17 printed to electronic textbooks in their social studies classes.
“I mean, it’s just 18 a regular textbook, except it’s got it all online.” says Luke Rosa, a history teacher at Falls Church High School.
Peter Noonan, an assistant superintendent(主管) of schools says, “The world’s changing 19 . And the online textbooks can change right along with the events that 20 .”
“Digital books also cost 21 than printed textbooks,” he says, “Usually it’s between fifty and seventy dollars 22 a textbook for each student, which adds up to about eight million dollars for all of our students in Fairfax County. In fact, we have bought all of the online textbooks for our students for just under six million dollars.”
Social studies teacher Michael Bambara says the e-book he uses in his government class is better than a(an) 23 textbook. It has materials for students 24 different levels of reading skills…

We sometimes call the lion “the king of the jungle (丛林)” because it is stronger and more dangerous than other animals. It can run faster than many animals and it can hunt (捕猎) the best. It is the highest animal in the 21 food chain (食物链).[
In the sea, the shark is one of the animals at the 22 of the food chain. It can swim faster than most other sea animals, and it can use its big teeth to eat them.
What is at the top of the world’s food chain? 23 are! We are not the biggest or fastest, but we are the 24 We could not run faster than cheetahs (猎豹), so we 25 cars and now we can move the fastest. We could not 26 better than lions, so we invented guns (枪). Now we can hunt the best.
People’s inventions are clever, but they can be dangerous, too. For example, people invented 27 , and now they make the air and rivers dirty. This can make 28 changes. Dirty rivers kill fish. Then bears cannot eat the fish and the bears die. If we kill one part of the food chain, 29 also die. Remember that we are a part of the food chain, so we are in danger too! If we protect animals, we are protecting 30 ! We should and we could do something for the world!

When Oakland High School in California moved into a new building, the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts (专家) came to find the cause of the sickness. Finally, they discovered that the air in the building was not safe to breathe. They were surprised to find out that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards(合成板). This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化学物质). This is just one example of a modern problem that is most common in cities—indoor air pollution(污染).
People have worried about air pollution for many years, and the government has spent lots of money trying to clean up the air of big cities. But now we found that we are still breathing unhealthy air. A study shows: Indoor air pollution is almost two to five time(倍) worse than outside pollution. So remember to open the windows and don’t stay too long in modern buildings with windows closed. Many students and teachers _________ after they moved into the new building.
A were very happy and excited B. didn’t feel well C. felt tired because of hard work The experts came to Oakland High School for _________.
A staying with the sick students and teachers
B. taking away the desks and chairs
C. finding the cause of the illness Which of the following is Not true according to the passage?
A. The indoor air pollution is common in cities.
B. We needn’t worry about the outside pollution.
C. The air in this school library was not safe to breathe. A study shows that indoor air pollution is _________.
A even worse than the outside pollution B. not so bad as outside pollution
C. the only problem to worry about What’s the main idea of the passage?
A Never move into a new building B. We shouldn’t buy cheap desks and chairs
C. The indoor air pollution is a big and common problem.
After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered an Earth-sized planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid（液态）water. Scientists think there is a chance that the planet could have life.
The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion（万亿）kilometres －500 million times farther away from us than the moon.
A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can’t live that long, but robotic explorers could make the job easier. However, our fastest spacecraft don’t come anywhere near that one-tenth light-speed mark.
At present, scientists don’t know what the surface might be like on Gliese 581g. What they know is that the planet is at the sight distance from its star to have liquid water. It’s also at the right distance to have an atmosphere that could protect the water if it is on the surface.
Although spacecraft won’t be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes（望远镜）towards the planet and search for radiation（放射）. By studying the radiation, scientists would find out about the chemicals（化学物质）around the planet and discover it Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea if the planet has life or not. But it’ll probably be many years before we can do this properly.
People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers. What did scientists find in September 2010?
| A．A planet with water. | B．A planet similar to the earth. |
| C．A planet without life. | D．A planet near the earth. |
According to the article, Gliese 581g ________.
| A．is at the right distance from its star | B．moves around the earth |
| C．is as far away from us as the moon | D．can be reached in about 220 years |
Paragraph 5 is mainly about ______.
| A．the possibility of living on Gliese 581g |
| B．the kinds of chemicals around Gliese 581g |
| C．the way of looking for life on Gliese 581g |
| D．the aim of studying the radiation on Gliese 581g |
Which of the following is the best title for the passage above?
| A．Gliese 581g, a Likely Living Planet | B．Gliese 581, a Likely Living Planet |
| C．Gliese 581g and Its Star | D．Gliese 581g and Radiation |
In Chicago, a computerized system has been developed that controls(管理)traffic on the city’s 235 miles of seven expressways. Now one—a controller—can follow the movement of Chicago’s traffic by looking at a set of lights. The system uses electric sensors(感应器) that are built into each expressway, every half a mile. Several times a second, the computer receives information from each sensor and translates it into green, yellow or red lights on a map in the control room. A green light means traffic is moving forty-five miles an hour, yellow means thirty to forty-five miles an hour, and red means heavy traffic—cars standing still or moving less than thirty miles an hour.
“See that red light near Austin Avenue?”the controller asked a visitor.“That’s a repair truck fixing the road, and the traffic has to go around it.”At the Roosevelt Road entrance to the expressway, the light kept changing from green to red and back to green again.“A lot of trucks get on the expressway there,”the controller explained.“They can’t speed up as fast as cars.”The sensors show immediately where an accident or a stopped car is blocking the tr
affic, and a truck is sent by radio to clear the road. The system has lowered the number of accidents by 18 percent. There are now 1.4 deaths on Chicago’s expressway for each one hundred million miles traveled, while in other parts of the county there are 2.6.
Traffic experts say that the Chicago system is the “coming thing”.Systems like Chicago’s are already in use on some expressways in Los Angeles and Houston.“Chicago has taken the lead,”said New York City’s traffic director and he added,“Chicago’s a good example.”

Look closely at your hands. Are they clean? It doesn't matter how many times you wash your hands, tiny microbes (微生物) still stay on them. But don't worry. Most microbes don't harm you.
Now scientists say the microbes on our hands cou
ld be used in a surprising way; fighting crime, According to a recent survey microbes as well as fingerprints(指纹) could be used to indentify the criminal.
Everyone has his own set of microbes on the hands. That is to say, if you and your best friend were able to see and compare all the microbes on your hands, your hands probably would look different. Some microbes only show up on your hands while others live only on your friend's hands.
When you work on a computer you leave the microbes from your hands on the keyboard. The scientists can easily tell the owner of the keyboard by looking at the microbes on it. Even if you don't leave your fingerprints behind, your microbes may give you away.
Noah Fierer, a scientist, says. "You can only clean a fingerprint, but you can't sterilize (使无菌
) a surface j
ust by wiping(擦) it off," He says that scientists have a lot more work to do before the microbe is used as a useful tool.According to the passage,_______ could be used to identify the criminal.
| A．fingerprints | B．scientists' hands |
| C．microbes | D．fingerprints and microbes on people's hands |
Paragraph 3 tells us that________.
| A．our hands look similar | B．the microbes will make the keyboard dirty. |
| C．we should compare hands often | D．we have our own sets of microbes. |
When you work on computer, the microbes________.
| A．just stay on our hands | B．also stay on the keyboard |
| C．will do harm to you | D．will disappear |
From Noah Fierer we know that________.
| A．fingerprints are no longer useful in fighting crime |
| B．microbes can be found on everyone's hands. |
| C．unlike microbe fingerprints can be cleaned if people wipe them |
| D．the microbe is used as a useful tool |
What’s the best title of the passage?
| A．Microbes May Tell Who You Are | B．Scientists Say Everyone Has Microbes |
| C．Noah Fiercer Does Research Into Microbes | D．Fingerprints Help Catch Cr iminals |
