.
Last month ,studenrs from 103 universities in 88 coontries took part in international computer programming contest. The Battle of the Brain took place in Harbin, China. Three---person terms from each school had hours to solve eleven real world problems.
Jerry Cain coached the team from Standford University in Palo Alto,California. He says the problems involved, among other things, paperweights, robots, castles and lakes.
JERRY CAIN: “One of the programming problems was trying to figure out how to break an chocolate bar into a certain number of pieces of a certain number of sizes and to do it as quickly as possible. And that’s probably the simplest of all them.”
The students first listed the problems in order of difficulty and then they wrote the needed software systems. They designed ways to test their solutions. And they wrote the needed software systems , Even the winning team from Shanghai Jiaotong University in China was not able to solved all the problems within the given time limit. Stanford’s team solved five problems and finished in fourteenth place. Standford was one of twenty---one America universities that took part in the conest this year. The conest began in 1970 at Texa A and M University. The first final competition was held in 1977 at the Association for Computer Machinery Computer Science Conference. It developed and grew as more and more schools took part in local and area contests.
Contest spokenman Doug Heintzman says the world champions receive prizes and scholarships. They are also guaranteed an offer of employment or practice period with IBM. “We’re had past world champions that IBM has given a post to in our Zurich research Iaboratory and they are now working on some of the Ieading edge materials in science and physics. So this competition is an opportunity to be recognized and to be recruited by some of the top technology and firms around the world “

Everyone hates to wait in lines. We get that anxious feeling that our precious life is slipping away while we’re doing something so meaningless. But it’s not always the length of the wait we find so unbearable. Some people camp outside Apple stores for an entire night just to get their hands on the latest product. But waiting 10 minutes in a grocery store just to buy a drink? Forget it.
Our behavior when waiting is only partly decided by the length of the wait. “Often the psychology of queuing is more important than the statistics of the wait itself,” notes the MIT researcher Richard Larson.
One apparent aspect of queuing psychology is that we get bored when we wait in line. This issue is solved in many ways, from magazines in hospital waiting rooms to mirrors in elevators so that we can check our appearance.
We really hate it when we expect a short wait and then get a long one. But studies show that we are much more patient when we are given an idea of how long we’ll be waiting.
Walt Disney Co knows this better than anyone else. It posts estimated waiting times for attractions in its theme parks. But according to Larson, these times are overestimated so that visitors get to the front of the queue more quickly than they expect. It keeps them happy.
But perhaps the biggest influence on our feelings about waiting in a line has to do with our sense of fairness. When it comes to queues, the universally acknowledged standard is first come, first served. Any departure from this principle is regarded as unfair and can lead to violent queue anger.
You’ve probably experienced mild queue anger yourself in fast food restaurants, watching people in the other line zoom ahead of you, cursing yourself for having chosen the “wrong” line. In order to solve this problem, the serpentine(蛇形) line was invented. The serpentine line guides all customers into one big snaking queue, separated by ropes or barriers. When you reach the head of the queue, you are directed to the next available server, or teller, or customs official. The serpentine line isn’t always faster than multi-lines before an array(排) of cash registers. But it offers important comfort: you absolutely never have to see someone arrive after you and get served before you.
In life, waiting is inevitable. But a better understanding of the psychology of waiting can help make it a bit more bearable. When all else fails, bring a book or a smart phone will also do.In the 1stparagraph, the author intends to tell us_____.

So long as teachers fail to distinguish between teaching and learning, they will continue to undertake to do for children that which only children can do for themselves. Teaching children to read is not passing reading on to them. It is certainly not endless hours spent in activities about reading. Douglas insists that “reading cannot be taught directly and schools should stop trying to do the impossible”.
Teaching and learning are two entirely different processes. They differ in kind and function. The function of teaching is to create the conditions and the climate that will make it possible for children to devise the most efficient system for teaching themselves to read. Teaching is also public activity. It can be seen and observed.
Learning to read involves all that each individual does to make sense of the world of printed language. Almost all of it is private, for learning is an occupation of the mind, and that process is not open to public scrutiny.
If teacher and learner roles are not interchangeable, what then can be done through teaching that will aid the child in the quest（探索）for knowledge? Smith has one principal rule for all teaching instructions. “Make learning to read easy, which means making reading a meaningful, enjoyable and frequent experience for children.”
When the roles of teacher and learner are seen for what they are, and when both teacher fulfill them appropriately, then much of the pressure and feeling of failure for both is eliminated. Learning to read is made easier when teachers create an environment where children are given the opportunity to solve the problem of leaning to read by reading.The problem with the reading course as mentioned in the first paragraph is that ________.
| A．it is one of the most difficult school courses |
| B．students spend endless hours in reading |
| C．reading tasks are assigned with little guidance |
| D．too much time is spent in teaching about reading |
The teaching of reading will be successful if ________.
| A．teachers can improve conditions at school for the students |
| B．teachers can enable students to develop their own way of reading |
| C．teachers can devise the most efficient system for reading |
| D．teachers can make their teaching activities observable |
The underlined word“ scrutiny” most probably means“________”.
| A．inquiry | B．observation | C．control | D．suspicion |
According to the passage, learning to read will no longer be a difficult task when ________.
| A．children become highly motivated |
| B．teacher and learner roles are interchangeable |
| C．teaching helps children in the search for knowledge |
| D．reading enriches children’s experience |
The main idea of the passage is that ________.
| A．teachers should do as little as possible in helping students learn to read |
| B．teachers should encourage students to read as widely as possible |
| C．reading ability is something acquired rather than taught |
| D．reading is more complicated that generally believed |
Many people take it for granted that black is a color of bad things while white should always mean something good. This may be because, in their opinion, black is related to darkness and white to purity. However, that is not always the case. Did you know that the same one color may mean differently in different places of the world?
In the English-speaking world, black is the color of mourning. People wear black clothes at the funeral. Red is concerned with danger or bloodshed (流血). Yellow is the word for fear. If you are afraid, you are yellow. Yet none of these sayings is true outside the English-speaking world. In China and Korea white is the color of mourning. In Russia, China and some other countries, red stands for beauty, life and excellence. In Italy and Germany, you are yellow with anger, not with fear.
Even within the English-speaking area it is not difficult to find color contradictions (矛盾). A redcap in the United States is a porter in a railway station. In Britain, however, a redcap is a military policeman. Both names are logical because both men wear red caps. Similarly, the British term for an American white collar worker is sometimes called a black-coated worker.
One does not have to cross an area to find color differences. Would you rather be red-blooded? If we go back to the origin, we find that both terms are logical as both names suggest. The expression "blueblood" comes from Spain, where some noble families proudly said that they had "blue blood". But then why "blue" blood? Because they were fairskinned, and it is only natural that their blood vessels (血管) stood out appearing blue.Yellow is concerned with anger in _______.
| A．Russia | B．Britain | C．Germany | D．China |
The two meanings of the term "redcap" form a difference in _______.
| A．pronunciation | B．climate | C．logical relationship | D．custom |
Both Britain and America would probably agree that _______.
| A．black is the color of mourning |
| B．a black-coated worker is employed in an office |
| C．red stands for beauty and excellence |
| D．a redcap is a porter in a station |
The best title for this passage is _______.
| A．The Origin of Blue Blood |
| B．The Development of the Symbolic Use of Colors |
| C．Colors that Carry Bad Meanings |
| D．The Meaning Concerned With Certain Colors |
When some Spanish called themselves "blueblood", they actually meant _______.
| A．they had heart trouble and their faces looked blue |
| B．they came from a noble family |
| C．they had blue blood in their vessels |
| D．they were fairskinned |
Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil (零), many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne (升空的).
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft.
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply (遵守) with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious , but it's worth listening to the flight attendants. And even if you've flown before, it doesn't mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence (气流).
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it's important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.What is the overall reason for these air safety tips?
| A．What to do in the event of a crash. |
| B．How to avoid turbulence. |
| C．How to improve safety while you are flying. |
| D．How to avoid injury. |
The underlined word "those" in the second tip refers to _______.
| A．smaller planes | B．passengers | C．larger aircraft | D．safety records |
The underlined phrase "The general rule" in the fifth tip refers to _______.
| A．anything the flight staff tell you to do |
| B．general safety advice |
| C．walking around the plane |
| D．pouring hot drinks |
Which of the following is NOT true?
| A．Larger planes have more safety checks and are safe in an accident. |
| B．Take-offs are safer on non-stop flights than landings. |
| C．Every aircraft is different, so the safety procedures may be different. |
| D．Seat belts should be worn to protect against turbulence. |
The best title of the passage should be _______.
| A．The Safest Way to Travel | B．Air Safety Tips |
| C．Non-stop Routes | D．How to Fly a Plane |
