A weather map is an important tool for geographers. A succession of three or four maps presents a continuous picture of weather changes. Weather forecasters are able to determine the speed of air masses and fronts. They are also able to determine whether an air mass is retaining its original characteristics or taking on those of the surface over which it is moving. Thus, a most significant function of the map is to reveal an synoptic picture(气象图) of conditions in the atmosphere at a given time.?

All students of geography should to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts and all climate conditions in general. Twice a month it issues a 30-day “outlook” which is a rough guide to weather conditions likely to occur over broad areas of the United States. These outlooks are based on an analysis of the upper air levels.?

With the use of electronic instruments and satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations(气象站).Experiments are also in progress for weather modification studies, although few successful results such as artificial rainmaking have been achieved so far.?

Which is not mentioned in this passage in the following about one characteristic of weather?

A. Fronts.       B. Temperature change. C. Wind speed.      D. Frost.?

The observation of weather conditions by satellites is advantageous because

_______.

A. it is modern and sophisticated?

B. it used electronic instruments?

C. it enables man to alter the weather?

D. it gives the scientists information not obtained readily otherwise?

The word “interpret” in Paragraph 2 most probably means _______

In the 1960s,medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They found out that any major change can be stressful. Negative events like “serious illness of a family member” were high on the list, but so were some positive life-changing events, like marriage. When you take the Holmes-Rahe test you must remember that the score does not show how you deal with stress—it only shows how much you have to deal with. And we now know that the way you deal with these events has a great effect on your chances of staying healthy.

By the early 1970s,hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow, the research got boiled down to a memorable message. Women's magazines ran headlines like “Stress causes illnesses”.If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. ven if stressful events are dangerous, many—like the death of a loved one—are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription(处方) for staying away from opportunities as well as trouble. Since any change can be stressful, a person who wanted to be ?completely? free of stress would never marry, have a child, take a new job or move.?

The idea that all stress makes you sick also takes no notice of what we know about people. It is supposed that we're all weak and passive in the face of difficulty. But many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom, and physical and mental damage.?

The result of Holmes-Rahe's medical research tells us _______.?

A. the way of dealing with major events may cause stress?

B. what should be done to avoid stress?

C. what kind of event would cause stress?

D. how to deal with sudden changes in life?

The studies on stress in the early 1970's led to_______.?

Some kids can't sit still for long. They have a hard time paying attention to just one thing. They're easily distracted(分神).They can get very impatient. They hate standing in line or waiting for their turn in a game or activity. They get bored pretty fast. They may also be impulsive—saying the first thing that comes to mind or interrupting someone else who's talking.?

For certain kids, this problem is so severe(严重) that doctors have a name for it: attention deficit hyperactivity disorder, or ADHD. Perhaps as many as 1 out of every 20 kids under the age of 18 have characteristics of ADHD. Often, these kids have trouble getting through school and face other difficulties later in life.?

Rizzo started developing the Virtual Classroom in 1999.He wanted to see if he could use it as a tool for testing and treating kids who have attention disorders.?

To diagnose(诊断) ADHD, doctors typically test patients by giving them tasks that require attention. As part of one classic test, you watch letters flashed on a computer screen. Every time you see the letter “A” followed by the letter “X”,you have to press the space bar. If you're paying close attention, you'll register all the times this combination occurs. If not, you'll miss some.?

The Virtual Classroom makes these tests more efficient, Rizzo says. In one experiment, he gave a group of kids the classic “A-X” test. Instead of looking at a computer screen in a doctor's office, though, the kids wore headsets that made it look like they were taking the test in a classroom.?

“Basically what we found,”Rizzo says,“is that, in 20 minutes of testing with virtual reality,?we? replicated(复制) a finding that usually requires a couple hours of standard testing with computer screens in the psychologist's office.”?

The first paragraph mainly tells us _______.?

A. how to find a patient with ADHD?

B. the behavior of some kids with ADHD?

C. kids with ADHD cannot sit still for a long time?

D. kids with ADHD are easily distracted
