Historian John Keegan writes: “Nuclear weapons have, since August 9, 1945, killed no one. The 50,000,000 who have died in war since that date have for the most part, been killed by cheap, mass-produced weapons and small ammunition, costing little more than the transistor radios which have flooded the world in the same period. Because small weapons have disrupted life very little in the advanced world, outside the restricted localities where drug-dealing and political terrorism flourish, the populations of the rich states have been slow to recognize the horror that this pollution has brought in its train.
Why have small arms become the weapons of choice in recent wars？ Part of the reason lies in the relationship between conflict and poverty. Most of the wars fought during the 1990s took place in countries that are poor----too poor to buy sophisticated weapon systems. Small arms and light weapons are a bargain. For example, 50 million dollars, which is approximately the cost of a single modern jet fighter, can equip an army with 200,000 assault rifles.
Another reason why small weapons are so popular is that they are lethal. A single rapid-fire assault rifle can fire hundreds of rounds a minute. They are also easy to use and maintain. A child of ten can be taught to strip and reassemble a typical assault rifle. A child can also quickly learn to aim and fire that rifle into a crowd of people.
The global traffic in guns is complex. The illegal trade of small arms is big. In some African wars, paramilitary groups have bought billions of dollars’ worth of small arms and light weapons, not with money, but with diamonds seized from diamond-mining areas.
Weapons are also linked to the illegal trade in drugs. It is not unusual for criminal organizations to use the same routes to smuggle drugs in one direction and to smuggle guns in the other.
11. It is implied in the passage that _____.
A、the nuclear arms-control talks can never reach an agreement
B、small arms-control is more important than nuclear arms-control
C、the power of nuclear weapons to kill people has been diminished
D、unclear weapons were the topic of arms-control talks 50 years ago
12. The advanced world neglect the problems of small arms because ____.
A、They have to deal with drug-dealing and political terrorism.
B、They have no such problems as are caused by small weapons.
C、They face other more important problems such as pollution.
D、They have not recognized the seriousness of the problems in time.
13. Which of the following is NOT mentioned as the reason for the prevalence of small arms？
A、Small arms are cheap.
B、Small arms are powerful.
C、Small arms are easier to use.
D、Small arms are easier to get.
14. We can conclude from the passage that _____.
A、small arms are not expensive in the black-market
B、it is unfair to exchange small arms for diamond
C、criminals use the same passage to smuggle drugs and small arms
D、where there are drugs, there are small arms
15. The best title for this passage is _____.

I’ve been writing for most of my life. The book Writing Without Teachers introduced me to one distinction and one practice that has helped my writing processes tremendously. The distinction is between the creative mind and the critical mind. While you need to employ both to get to a finished result, they cannot work in parallel no matter how much we might like to think so.
Trying to criticize writing on the fly is possibly the single greatest barrier to writing that most of us encounter. If you are listening to that 5th grade English teacher correct your grammar while you are trying to capture a fleeting (稍纵即逝的) thought, the thought will die. If you capture the fleeting thought and simply share it with the world in raw form, no one is likely to understand. You must learn to create first and then criticize if you want to make writing the tool for thinking that it is.
When the author says the creative mind and the critical mind “cannot work in parallel” (Line 4, Para. 1) in the writing process, he means ________.
A) no one can be both creative and critical
B) they cannot be regarded as equally important
C) they are in constant conflict with each other
D) one cannot use them at the same time（D）
In the modern technology world, the sea offers many resources to help mankind survive.Resources on land are beginning to grow less.The sea, however, still offers hope to supply many of man’s needs in the future.
The riches of the sea yet to be developed by man’s technology are impressive.Oil and gas explorations have existed for nearly thirty years.Valuable amounts of minerals such as iron, copper and so on exist on the ocean floor.
Besides oil and gas, the sea may offer new sources of energy.For example, warm temperature of the ocean can be used as the steam in a steamship.Sea may also offer a source of energy as electricity for mankind.
Technology is enabling man to explore even deeper under the sea.It is obvious that the technology to harvest the sea continues to improve.By 2050, experts believe that the problems to explore the food,
minerals and energy resources of the sea will have been largely solved.

brain alone, but that one’s muscles also participate (take part in). It may be said that we think with our muscles in somewhat the same way that we listen to music with our bodies.
You surely are not surprised to be told that you usually listen to music not only with your cars but with your whole body. Few people can listen to music that is more or less familiar without moving their body or, more specifically, some part of their body. Often when one listens to a symphonic concert on the radio, he is tempted to direct the orchestra (music band) even though he knows there is a competent conductor on the job.
Strange as this behavior. may be, there is a very good reason for it. One cannot derive all possible enjoyment from music unless he participates, so to speak, in its performance. The listener "feels" himself into the music with more or less pronounced motions of his body.
The muscles of the body actually participate in the mental process of thinking in the same way, but this participation is less obvious because it is less pronounced.
1、Few people are able to listen to familiar music without ______.
A、moving some part of their body
B、stopping what they arc doing to listen
C、directing the orchestra playing it
D、wishing that they could conduct music properly
2、Body movements are necessary in order for the listener to ______.
A、hear the music
B、enjoy the music fully
C、appreciate the music completely
D、understand the music
3、The best title for this selection is______.
A、An Ear for Music
B、Music Appreciation
C、How Muscles Participate in Menial Acts
D、A Psychological Definition of the Thinking Process
4、The pronounced body motions are a listener’s way of ______.
A、"feeling" the music
B、participating in the performance
C、deriving enjoyment from the music
D、all of the above
5、Some psychologists maintain that thinking is ______.
A、not a mental process
B、more of a physical process than a mental action
C、a process that involves our entire bodies
D、a process that involves the muscles as well as the brain
