Questions 29 to 32 are based on the following passage：
　　Tests conducted at the University of Pennsylvania's Psycho1ical Laboratory showed that anger is one of the most difficult Emotions to find out from facial expressions. Professor Dallas E. Buzby confronted 716 students with pictures of extreme1y angry persons， and asked them to identify the emotion from the facial expression。 Only two percent made correct judgments. Anger was most frequently judged as“pleased”.
　　And a typical reaction of a student confronted with the picture of aman who was mad was to classify his expression as either ‘bewildered’，‘quizzical’，or simply‘amazed’．Other studies showed that it is extremely difficult to tell whether a man is angry or not just by looking at his face. The investigators found further that women are better at finding out anger from facia1 expressions than men are. Paradoxically，they found that psychological training does not improve one’s ability tojudge a man’s emotions by his expressions but actually hinders it． For in the university tests， the more courses the student had taken in psychology， the poorer judgment score he turned in.

　　A. use adults rather than students as judges
　　B. ask women who do not study psychology to judge it
　　C. ask men rather than women to judge it
　　D. be satisfied with a two percent success，if such a percentage is guaranteed
　　32．The last two sentences in the second paragraph show that__________.
　　A. such training has not resulted in better scores
　　B. we have really achieved the anticipated results
　　C. the judgment is similar to what we have expected
　　D.we can expect such training to have the effect stated
　　Questions 33 to 36 are based on the following passage：
　　Wouldn't it be great if you could just look up at the sky and read the weather forecast right away？
　　Well, you Can. The forecast is written in c1ouds. If you can read that writing，you can tell something about the atmosphere. With some practice， you can become a pretty good weather forecaster．Who knows，you might even do as well as meteorologists.
　　Meteorologists use much more information than just the appearance of the clouds to make their forecast．They collect data from all over the world． Then they put it into powerful，high-speed computers.
　　This does give meteorologists an advantage，because they can track weather patterns as they move from west to east across the country.
But you have an advantage，too.You can look at the sky and get your data directly．A meteorologist uses a computer forecast that’s several hours old to make a 1ocal forecast.
　　What are you seeing when you look at a cloud？”A picture of what moisture is doing in the atmosphere,” says meteorologist Peter Leavit ． There’s moisture throughout the atmosphere. Most of the time you don't see it，because it's in the form of an invisible gas called water vapor.
Sometimes，the temperature of the air gets cold enough to cause the water vapor to change to liquid water．That’s called condensation， and we see it happen all the time (for example，when humid air from the shower hits the cold glass of a mirror). When enough water vapor condenses，droplets form in the air.These droplets scatter light．A cloud is seen.
　　Watching c1ouds over a day or two tells you a lot more than a sing1e cloud about the weather to come， Changes in clouds show changes in the atmosphere.
You should begin to notice patterns. Certain clouds， fol1owing each other in order， can signal an approaching storm. But don’t take our word for it； see for yourself.
　　33．This passage main1y tells us about how__________.
　　A. to become a meteorologist
　　B. to keep an eye on the weather
　　C. to be an assistant to a meteorologist
　　D. to change water vapor to liquid water
　　34．According to the passage，an ordinary person might do as well as a meteorologist in weather forecast_____________.
　　A. with the help of the high-speed computers
　　B. through a complex process of calculation
　　C. with some simple practice looking up at the sky
　　D. consulting a weather station
　　35．Meteorologists make their weather forecast__________.
　　A. by collecting data from all over the world
　　B. by putting this date into powerfu1， high，speed computer
　　C. by ca1culating and ana1yzirig this data
　　D. all above
　　36.Your advantage in weather forecasts is that____________.
　　A. you have more powerful computers at home
　　B. your brain works as well as a high-speed computer
　　C. you observe the sky and obtain your data directly
　　D. meteorologists give their data to you as soon as they get them
　　Questions 37 to 40 are based on the following passage：
　　Security and commodity exchanges are trading posts where people meet who wish to buy or sell． The exchanges themselves do no trading；they merely provide a place where prospective buyers and sellers can meet and conduct their business.
　　Wall Street， although the best known， is not the only home of exchanges in the United States. There are cotton exchanges in New Orleans and Chicago； the Mercantile Exchange， which deals in many farm products， in Chicago； and grain exchanges in many of the large cities of the Midwest. home exchanges， like the Chicago Board of Trade， provide market services for several kinds of products. These tradingposts where products may be bought or sold are called commodity exchanges.
　　The security exchanges， on the other hand, are meeting places where stocks and bonds are traded． Like the commodity exchanges ， they help serve the economic life of t he country. But when their operations get out of hand， they may become very dangerous．In l929， the security exchanges，or stock market， contributed to a crash a sudden， sharp decline in the value of securities. Many people lost fortunes；many corporations were bankrupted； many workers lost their jobs. The Crash of l929 has been attributed to many causes， among them wild and unwise speculation by many people and dishonest practices on the part of some businessmen and of some members of the exchanges.
　　Today，however，investing through security exchanges and trading on commodity exchanges has been made safer by regulations set up by the exchanges themselves and by regulations of the United States government， In l922，the government instituted the Commodity Exchange Commission which operated through the Department of Agriculture； and in l934，the Securities and Exchanges Commission， to protect investors and the public against dishonest practices on the exchanges.
