A good teacher is many things to many people. In my own experience, the people I respect the most and think about the most are the teachers who demanded (要求) the most discipline (纪律) from their students.
I miss one teacher in particular that I had in high school. I think she was a good teacher because she was a very strict person. I remember very vividly (清晰地) a sign over her classroom door. It was a simple sign that said, “Laboratory—in this room the first five letters of the word was emphasized (强调), not the last seven.” In other words, I guess, labor for her was more important than oratory, which means making speeches.
She prepared her work very carefully and demanded us to do the same. We got lots of homework from her. Once she had broken her arm, and everybody in the class thought that maybe the homework load would be reduced, but it continued just the same. She checked our work by stamping her name at the bottom of the papers to show that she had read them.
I think sometimes teachers who demand the most are liked the least. But as time goes by, this discipline really seems to benefit (有益于) the students.
小题1:Which of the following is considered a good teacher by the writer?

A．A patient teacher.	B．An honest teacher.

BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips（微芯片） and start using their own "Chinese core(核心)", according to one of the country"s leading scientists, Hu Weiwu.
Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second.
Making supercomputers with Chinese microchips is one of the nation"s major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects.
According to their schedules, all three institutions will need to meet the target of using domestically（国内的） developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient.
Tianhe-1A, developed by NUDT in Hunan"s provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers.
Hu said there will be difficulties ahead as there is little affiliated equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can"t make full use of them," He said.
Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.
小题1:What’s the best title for this passage?

A．The Arrival of Chinese Supercomputers

During adolescence(青春期), peers（同龄人） play a large part in a young person"s life and typically replace family as the center of a teen"s social activities. Some kids give in to peer pressure because they want to be liked or because they worry that other kids may make fun of them if they don"t go along with the group. Others may go along because they are curious to try something new that others are doing. The idea that "everyone"s doing it" may influence some kids to leave their better judgment, or their common sense, behind.
As children grow, develop, and move into early adolescence, contacts with one"s peers and the attraction of peer identification (认同)increases. As pre-adolescents begin rapid physical, emotional and social changes, they begin to question adult standards and the need for parental guidance. They find it good to turn for advice to friends who understand— friends who are in the same position themselves. By trying new things and testing their ideas with their peers, there is less fear of being laughed at.
There are two levels of peer pressure. The first is in the large group: for most teens a school or a youth group are examples. This is the situation that gets the most attention. The second is in the close relationship with one or several best friends. This is the situation that is sometimes disregarded. The large group puts a general pressure on its members. It sets the standard for clothing, music, entertainment, and "political correctness". The pressure can be avoided by keeping quiet or by putting on the appearance of agreement.
小题1:Why can’t some children follow their common sense?

A．Because they want to be liked by everybody.

B．Because they don’t want to make fun of others.

C．Because they are curious about their new friends.

D．Because they think all the children will do the same.

小题2:When in pre-adolescence, who may children ask for suggestions?

A．Parents

B．Teachers

C．Friends

D．Classmates

小题3:Which word can replace the underlined word disregarded in the last paragraph?

A．unnoticed

B．mentioned

C．disagreed

D．avoided

小题4:What might be discussed in the following paragraph?

A．The reasons of peer pressure.

B．The advantages of peer pressure.

C．Peer pressure from close friends.

D．Peer pressure from a youth group.

Today, when a fire breaks out, you can be sure a citizen with a cell-phone camera has posted it to Facebook or Twitter, or sent it to the media. But up to now, that citizen has not been able to easily send images and details of what is happening to the people who need it most: police, firefighters and building-security people who must respond, and whose ability to help is often measured in minutes, if not seconds.
That"s about to change. A one-year old company called Elerts has developed a system that"s designed to mobile and social technologies to speed the flow of information between citizens and emergency workers in time of danger. The system involves free mobile applications—iPhone and iPad app（应用软件）is available now—that eyewitnesses can use to report incidents and get public-safety warnings. And Elerts is offering a management console（控制台）for security firms and universities to receive the reports and distribute warnings and instructions, like a map with the best evacuation route（疏散路线）.
The service is the brainchild of Chris Russo, deputy fire chief in the coastal town of Hull, Mass. As mobile communications sped up, he grew increasingly frustrated by his inability to communicate effectively with colleagues and the public, particularly with people who are at the scene and might be able to provide help.
"Remembering situations when communications failed puts a pit in my stomach," Mr. Russo says. Last summer, he was in a search at a beach for a missing boy, who went into a bathhouse but didn"t come out. First responders feared an abduction （绑架） on the beach or shark attack. The child"s mother, who didn"t speak English well, was so sad that she couldn"t remember what color shorts he had on. Mr. Russo had no photo of the child, and no ability to turn to beachgoers.
Two long hours later, the boy was spotted by a low-flying helicopter lost and alone on the beach crying—a lucky break. "If 5 percent of beachgoers had an app to receive a message and send in sightings of a lost boy, the happy ending might have come much sooner," Mr. Russo said.
小题1:What is the passage mainly about?

A．A moving story of Chris Russo．	B．An app for reporting emergency．
C．A cell-phone instant service．	D．An app for firm management．

小题2:What does the underlined part in Paragraph 4 most probably mean?

A．Makes me feel frustrated．	B．Causes a stomachache．
C．Arouses my interest．	D．Leaves a hole in my stomach．

小题3:We can infer from the passage that emergency workers ____．

A．have to carry out rescue work in minutes

B．must send images and details immediately

C．need images and detailed information badly

D．have to turn to Facebook and Twitter for details

小题4:The author takes Chris Russo"s experience as an example to ____．

A．advertise his creativity in communication

B．show readers the working principle of the new system

C．make the passage more interesting to read

D．inform readers how Russo got the idea of the service

A machine which makes water out of air could become the greatest household invention since the microwave． Using the same technology as a dehumidifier (除湿器)， the Water Mill is able to create a ready supply of drinking water by getting it from a limitless source－the air． The company behind the machine says not only does it offer all alterative to bottled water in developed countries，but it is a solution for the millions who face a daily water shortage．
The machine works by drawing in damp air through a filter(过滤器) and over a cooling element which changes it into water droplets．It can produce up to 12 liters a day．The Water Mill will also produce more water when storms pass over, as the humidity（湿度）in the air increases．In keeping with its ecodevelopment，the machine uses the same amount of electricity as three light bulbs．
Inventor Jonathan Ritchey said：“The demand for water is off the chart．People are looking for freedom from water distribution systems that are shaky and unreliable”．
The machine，which is about 3 feet wide，is likely to cost￡800 when it goes on sale here in the spring．Its maker, Canadian firm Element Four, estimates that a liter of water will cost around 20 pence to produce．
Environmentalists claim half the world’s population will face water shortage because of climate change by 2080．One in five humans is said to lack access to safe drinking water．
The Water Mill is not effective in areas with below about 30 percent relative humidity, but with average relative humidity in England of more than 70 percent that won’t be much of an issue here.
小题1:According to the author, the biggest advantage of the machine is its ______．

A．little power use

B．unlimited source

C．proper size

D．high production

小题2:We can conclude from the passage that the machine________．

A．can be used everywhere

(2013·宜春五校联考)Technology is making life easier for some dairy farmers.They use robotic systems to milk their cows.Cows are trained to follow a series of paths that lead to milking stations.Only one cow at a time can enter a station.
Once inside，the cow is rewarded with food.As the cow eats，a robotic arm cleans and connects the animal to the milking machine.A few minutes later，milking is complete.The gate is opened，the cow is released and the next cow enters.
The robotic systems are designed to operate 24 hours a day.The cows get to decide when they want to be milked.Cows are milked an average of about three times a day.Some are milked four to six times a day.
The cows wear collars around their necks that identify them to the system.A computer keeps records on their eating and milking.A cow is released from the station if the computer decides it should not be milked.
The automated system also measures the temperature and color of freshly produced milk.Milk is thrown away if it does not pass the tests.
Professor Plaut believes the systems will appeal especially to the next generation of farmers.She means young people who are more interested in technology and less interested in working all the time on the farm.Still，she says the price of robotic milking systems will continue to limit their use.
Doug and Tina Suhr have more than 100 cows on their family farm.Last year it became the fourth farm in southeast Minnesota to get a robotic milking system.A recent story in a local agricultural newspaper said the first robot costs 175,000 dollars.The second costs 150,000 dollars.
Doug told AgriNews that wages that would have been paid for one employee in five years will pay for one robot.He says the increase in milk production reaches a high of more than six kilograms per cow per day.
小题1:From the first paragraph，we can infer ________.

A．the robotic system is designed to reduce labor

B．cows can be raised by robots in the future

C．robots direct cows into milking stations

D．cows are kept clean by robots on some farms

小题2:Besides milking cows，the robotic system also can ________.

A．adjust the temperature of milking stations

B．judge the quality of fresh milk

C．improve the appetite of cows

D．keep fresh milk for two weeks

小题3:Why is the robotic system not popular now?

A．Because young people have no interest in it.

B．Because it is difficult to learn how to use it.

C．Because people can"t afford to buy it.

D．Because it usually causes the waste of milk.

小题4:According to Doug，what is the wage of an employee per year?

A．$150,000～$175,000.

B．over $75,000.

C．$150,000～$30,000.

D．$30,000～$35,000.
