The dust particles of dust were shown at a higher

8、 magnification than anything outside of Earth that has been imaged before. The rounded particle measured only about one micrometer, or one millionth of a meter, across.“Taking this image required the highest resolution microscope operated off Earth and a specially designed device to hold the Martian

9、 dust,“ said Tom Pike, a Phoenix science team member from Imperial College London. “We always knew it was going to be technically very challenging to image particles this small.“The device that imaged the dust speck is called an atomic force microscope, which maps the shape of particles in three dim

10、ensions by scanning them with a sharp tip at the end of a spring. The atomic force microscope can detail the shapes of particles as small as about 100 nanometers. And this wont be the last dust particle that Phoenix will image. “After this first success, were now working on building up a portrait ga

11、llery of the dust on Mars,“ Pike said.Dust exists everywhere on Mars, coating the surface and giving it its rusty red color. Dust particles also color the Martian sky pink and feed storms that regularly envelope the planet. The ultra-fine dust is the medium that actively links gases in the Martian a

12、tmosphere to processes in Martian soil, so it is critically important to understanding Mars environment, the researchers said.The $420-million Phoenix mission is analyzing the dust and subsurface ice layers of Mars arctic regions to look for signs of potential past habitability.

20、、第一篇(总题数：1，分数：15.00)More Than a Ride to SchoolThe National Education Association claims. “The school bus is a mirror of the community.“ They further add that, unfortunately, what appears on the exterior does not always reflect the reality of a chosen community. They are right, sometimes it reflects

21、more! Just ask Liesl Denson. Riding the school bus has been more than a ride to school for Liesl.Bruce Hardy school bus driver for Althouse BUS Company has been Liesls bus driver since kindergarten. Last year when Liesls family moved to Parkesburg, knowing her bus went by her new residence, she requ

22、ested to ride the same bus.This year Liesl is a senior and will enjoy her last year riding the bus. She says, “Its been a great ride so far! My bus driver is so cool and has always been a good friend and a good listener. Sometimes when youre a child adults do not think that what you have to say is i

23、mportant. Mr. Hardy always listens to what you have to say and makes you feel important. “ Her friends Ashley Batista and Amanda Wolfe agree.Bruce Hardy has been making Octorara students feel special since 1975. This year he will celebrate 30 years working for Althouse Bus Company, Larry Althouse, p

24、resident of the company, acknowledges Bruce Hardys outstanding record: “You do not come by employees like Bruce these days. He has never missed a day of work and has a perfect driving record. He was recognized in 2000 by the Pennsylvania School Bus Association for driving 350,000 accident free miles

25、. Hardys reputation is made further evident through the relationships he has made with the students that ride his bus.“Althouse further adds, “Althouse Bus Company was established 70 years ago and has been providing quality transportation ever since. My grandfather started the business with one bus.

26、 Althouse Bus Company is delighted to have the opportunity to bring distinctive and safe service to our local school and community and looks forward to continuing to provide quality service for many more years to come.“Three generations of business is not all the company has enjoyed.

30、free driving lessonsD.building sound relationships六、第二篇(总题数：1，分数：15.00)A Phone That Knows Youre BusyIts a modem problem: youre too busy to be disturbed by incessant (连续不断的) phone calls so you turn your cellphone off. But if you dont remember to turn it back on when youre less busy, you could miss so

31、me important calls if only the phone knew when it was wise to interrupt you, you wouldnt have to turn it off at all. Instead, it could let calls through when you are not too busy.A bunch of behavior sensors and a clever piece of software could do just that, by analyzing your behavior to determine if

32、 its a good time to interrupt you. If built into a phone, the system may decide youre too busy and ask the caller to leave a message or ring back later.James Fogarty and Scott Hudson at Carnegie Mellon University in Pennsylvania based their system oil tiny microphones, cameras and touch sensors that

33、 reveal body language and activity. First they had to study different behaviors to find out which ones strongly predict whether your mind is interrupted.The potential “busyness“ signals they focused on included whether the office doors were left open or closed, the time of day, if other people were

34、with the person in question, how close they were to each other, and whether or not the computer was in use.The sensors monitored these and many other factors while four subjects were at work. At random intervals, the subjects rated how interruptible they were on a scale ranging from “highly interrup

35、tible“ to “highly not-interruptible“. Their ratings were then correlated with the various behaviors. “It is a shotgun (随意的) approach: we used all the indicators we could think of and then let statistics find out which were important,“ says Hudson.The model showed that using the keyboard, and talking

36、 on a landline or to someone else in the office correlated most strongly with how interruptible the subjects judged themselves to be.Interestingly, the computer was actually better than people at predicting when someone was too busy to be interrupted. The computer got it right 82 percent of the time

37、, humans 77 percent. Fogarty speculates that this might be because people doing the interrupting are inevitably biased towards delivering their message, whereas computers dont care.The first application for Hudson and Fogartys system is likely to be in an instant messaging system, followed by office

38、 phones and cell phones. “There is no technological roadblock (障碍) to it being deployed in a couple of years, “ says Hudson.（分数：15.00）(1).A big problem facing people today is that_.（分数：3.00）A.they must tolerate phone disturbances or miss important callsB.they must turn off their phones to keep their

39、 homes quietC.they have to switch from a desktop phone to a cell phoneD.they are too busy to make phone calls(2).The behavior sensor and software system built in a phone_.（分数：3.00）A.could help store messagesB.could send messages instantlyC.could tell when it is wise to interrupt youD.could identify

40、important phone calls(3).Scientists at Carnegie Mellon University tried to find out_.（分数：3.00）A.why office doors were often left openB.when it was a good time to turn off the computerC.what questions office workers were bothered withD.which behaviors could tell whether a person was busy(4).During th

41、e experiment, the subjects were asked_.（分数：3.00）A.to control the sensors and the camera.B.to rate the degrees to which they could be interrupted.C.to compare their behaviors with others.D.to analyze all the indicators of interruption.(5).The computer performed better than people in the study because

42、_.（分数：3.00）A.the computer worked harderB.the computer was not busyC.people tended to be biasedD.people were not good at statistics七、第三篇(总题数：1，分数：15.00)The Exploding Lakes of CameroonWhat comes to mind when you think of a lake? You probably imagine a pretty scene with blue water, birds, and fish. For

43、 the people in the northwestern Cameroon, however, the image is very different. For them, lakes may mean terrible disasters. In 1984, poisonous gases exploded out of Lake Monoun and came down into the nearby villages, killing thirty-seven people. Two years later, Lake Nyos erupted a cloud of gases r

44、olled down the hills and into the valleys and killed 1,700 people.Lake Nyos and Lake Monoun are crater (火山口) lakes. They were formed when water collected in the craters of old volcanoes. The volcanoes under Lake Nyos and Lake Monoun are not active anymore. However, poisonous gases from the center of

45、 the earth continue to flow up through cracks in the bottom of the lake. This is normal in a crater lake. In most crater lakes, these gases are released often because the water “turns over“ regularly. That is, the water from the bottom of the lake rises and mixes with the water at the top, allowing

46、the gases to escape slowly.However, in Lakes Nyos and Monoun, there is no regular turning over. No one knows the reason for this fact, but as a result, these lakes have more gases tapped at the bottom than other crater lakes. In fact, scientists who have studied Lakes Nyos and Monoun have found 16,0

47、00 times more gases. When a strong wind, cool weather a storm, or a landslide causes the water to turn over suddenly, the gases escape in a violent explosion.In the past, no one knew when the gases might explode, so there was no way for the villagers to escape disaster. Now scientists from the Unite

48、d States, France, and Cameroon have found a way to reduce the gas pressure at the bottom of Lake Nyos. They stood a 672-foot plastic pipe in the middle of the lake, with one end of the pipe near the bottom and the other end in the air. Near the top of the pipe, the team put several holes that could be opened or closed by a computer. Now, when the gas pressure gets too high, the holes are opened and some of the gas-filled water shoots up through the pipe into the air like a fountain. With less pressure, a disastrous explosion is much less likely. However, the scientists are not sure th
