Learn about Light
1 .Ancient civilizations were amazed by the existence of light for thousands of years. The Greek philosophers believed that light was made up of countless,tiny particles that enter the human eye and create what we call vision. However,Empedocles and a Dutch scientist named Christian Huygens believed that light was like a wave. According to them,light spread out and travelled like a straight line. This theory was accepted during the 19th century.
2 .In 1905,Albert Einstein published a research paper in which he explained what is re-ferred to as the photoelectric effect. This theory explains that particles make up light.The particles Einstein was referring to are weightless bundles（束）of electromagnetic（电磁）energy called photons（光子）.Today,scientists agree that light has a dual（二重）nature一it is part particle and part wave. It is a form of energy that allows us to see things around us.
3 .Things that give off light are known as sources of light. During the day,the primary source of light is the sun. Other sources of light include stars,flames,flashlights,street lamps and glowing gases in glass tube.
4 .When we draw the way light travels we always use straight lines. This is because nor-mally light rays travel in a straight line. However,there are some instances that can change the path and even the nature of light. They are reflection,absorption,interference（干扰）, etc.
5 .Physicists have attempted to measure the speed of light since the early times. In 1849, Hippolyte Fizeau conducted an experiment by directing a beam of light to a mirror located kilometers away and placed a rotating cogwheel（旋转齿轮）between the beam and the mirror. From the rate of rotation of the wheel,number of wheel's teeth and distance of the mirror,he was able to calculate that the speed of light is 313 million meters per second. In a vacuum（真空）,however,the speed of light is 299,792,458 meters per second. This is about a million times faster than the speed of an airplane.

Hippolyte Fizeau conducted an experiment to measure______.
A: sources of light
B: the speed of light
C: the path of light
D: a straight line
E: a beam of light
F: a form of energy

Why Have Formal Documents

Finally, writing the decisions down is essential. Only when one writes do the gaps appear and the (71) protrude(突出). The act of writing turns out to require hundreds of mini-decisions, and it is the existence of these that distinguishes clear, exact policies from fuzzy ones.

Second, the documents will communicate the decisions to others. The manager will be continually amazed that policies he took for common knowledge are totally unknown by some member of his team. Since his fundamental job is to keep everybody going in the (72) direction, his chief daily task will be communication, not decision-making, and his documents will immensely (73) this load.

Finally, a manager’s documents give him a data base and checklist. By reviewing them (74) he sees where he is, and he sees what changes of emphasis or shifts in direction are needed.

The task of the manager is to develop a plan and then to realize it. But only the written plan is precise and communicable. Such a plan consists of documents on what, when, how much, where, and who. This small set of critical documents ( ) much of the manager’s work. If their comprehensive and critical nature is recognized in the beginning, the manager can approach them as friendly tools rather than annoying busywork. He will set his direction much more crisply and quickly by doing so..

A.decides
B.encapsulates
C.realizes
D.recognizes

Alcoholism
1 .Yes,alcoholism can be treated. Alcoholism treatment programs use both counseling and medication（药物治疗）to help a person stop drinking. Most alcoholics need help to recover from their disease. With support and treatment,many people are able to stop drinking and rebuild their lives.
2. A range of medication is used to treat alcoholism. Benzodiazepines（苯二氮平类药物） are sometimes used during the first days after a person stops drinking to help him or her safely withdraw from alcohol. However,these medications are not used beyond the first few days because they may be highly addictive. Other medications help people remain sober（清醒）. One medication used for this purpose is naltrexone（环丙甲经二经吗啡酮) . When combined with counseling,naltrexone can reduce the strong desire for alcohol and help prevent a person from returning to heavy drinking. Another medication, disulfiram（戒酒硫）,discourages drinking by making the person feel sick if he or she drinks alcohol. Though several medications help treat alcoholism,there is no“magic bullet”.Developing new and more effective medications to treat alcoholism remains a high priority for researchers.
3 .Alcoholism treatment works for many people. But just like any chronic disease,there are different levels of success in treatment.Some people stop drinking and remain sober. Others cannot stop drinking for any length of time. With treatment,one thing is clear,however,the longer a person stops drinking alcohol,the more likely he or she will be able to stay sober.
4 .No,alcoholism cannot be cured at this time. Even if an alcoholic hasn't been drinking for a long time,he or she can still return to the drinking habit.To guard against it,an alcoholic must continue to avoid all alcoholic drinks.

Disulfiram can prevent drinking by making the alcoholic______.
A: stay confused
B: alcoholic drinks
C: medical treatment
D: feel sick
E: in every person
F: stop drinking

A Very Slow Ride

The surface of the earth may seem very stable to you.But you might be amazed if you
knew some of the things that are going on under that surface.
The earth has an outer shell of rigid pieces called tectonic plates（地壳构造板块）.The
plates include both ocean floor and dry land.Some have whole continents on top of them.
The continents on top of the plates are just going along for a slow ride,moving only about
four inches per year. But even this small movement causes three types of big interactions.
One type is ocean ridges.These ridges develop in places where two plates are moving
away from each other. As the plates separate , hot magma（岩浆）flows up to fill the
space. New crust（地壳）builds up on the plate boundaries and causes ocean ridges.
These ridges form long mountain ranges,which only rise above the ocean surface in a few
places.
Another type of reaction-trenches-occurs between two plates that are moving toward
each other.As the plates meet,one bends downward and plunges underneath the other.
This forms deep ocean trenches.The Marianas Trench off Guam in the western Pacific
Ocean has a depth of more than 36,000 feet.This is the lowest point on the ocean floor.
If the leading edges of the two colliding plates carry continents,then the layers of rock in the
overriding plate crumple（变皱）and fold. A plate that carried what is now India collided with
the southern edge of the plate that carried Europe and most of Asia.This caused the
Himalayas,the world's highest mountains.
The third reaction is transform faults（转换断层）.These faults occur where two plates
that are traveling in opposite directions slide past each other.Severe earthquakes can
occur. The San Andreas Fault in California is a good example of this type of movement.

To explain the effect of trenches,the writer gives the example of
A:the sea floor in the Atlantic Ocean.
B:the Himalayan Mountains.
C:Europe.
D:India.
