According to figures from the U.S. Bureau of Labor Statistics, the average weekly income f

or a woman in 1983 was $ 260. For the same year, men had average weekly earnings of $ 393. For some people, these figures are clear evidence that there is still sex discrimination in the area of pay in the U. S. However, I would argue that this explanation is too simple. In order to get an accurate picture of the situation, we must examine the types of jobs which are typically held by men and by women. When we do this, we find that certain occupations seem to be primarily female while others seem to be primarily male occupations. In the medical and legal professions, for example, statistics show that 85% of all doctors and lawyers are men (although this situation is changing). More than 90% of all engineers are men. Women, however, have been the majority for a long time in other occupations. For example, 99 out of every 100 secretaries are women, and 95% of all nurses are female. From these statistics, it is clear that women tend to enter certain occupations and not others. The occupations which they enter are often in service industries and often have one common feature: They do not pay well. It can be argued that this is the principal reason for the difference in earnings between men and women. In addition, we can expect the pay situation to change in the future, because more qualified women are beginning careers in medicine, law, business, scientific research, and engineering.

What jobs have typically been held by women？

A．Jobs as doctors and lawyers.

B．Jobs in service industries.

C．Jobs in areas without sex discrimination.

D．Jobs in areas where women are respected.

The difference between biological and physical science is not that one is inexact, the oth

er exact, but in degree of exactness, this being related to the number of variables which must be dealt with simultaneously and the extent to which they can be controlled. In general, the biological sciences must deal with larger errors than the physical sciences; but this is not uniformly true, as the student will realize when he considers the accuracy of meteorological prediction or if he comprehends the meaning of the fact that the structural engineer considers it necessary very often to use a safety factor of two or three hundred per cent. The statistical principles of dealing with error of measurement, or in prediction and generalization, are the same whether the errors are large or small. Statistics is not a means of confusing issues that would otherwise be clear, nor a substitute for obtaining clear answers, but a means of checking and controlling conclusions by providing an estimate of the error to which a conclusion is subject.

What do statistics do for science？

A．They get rid of intuition,

B．They make it more logical.

C．They reduce everything to numbers.

D．They give an idea of the amount of error involved.

According to airline industry statistics, almost 90% of airline accidents are not survivab

le or partially survivable. But passengers can increase their chances of survival by learning and following certain tips. Experts say that you should read and listen to safety instructions before takeoff and ask question if you have uncertainties. You should fasten your seat belt low on your hips and as possible. Of course, you should also know how the release mechanism of your belt operates. During takeoffs and landings you are advised to keep your feet flat on the floor. Before takeoff you should locate the nearest exit and an alternative exit and count the rows of seats between you and the exits so that you can find them in the dark if necessary.

In the event that you are forewarned of a possible accident, you should put your hands on your ankles and keep your head down until the plane comes to a complete stop. If smoke is present in the cabin, you should keep your head low and cover your face with napkins, towels, or clothing. If possible, wet these for added protection against smoke inhalation. To evacuate as quickly as possible, follow crew commands and do not take personal belongings with you. Do not jump on escape slides before they are fully inflated, and when you jump, do so with your arms and legs extended in front of you. When you get to the ground, you should move away from the plane as quickly as possible, and never smoke near the wreckage.

According to the experts, when should travelers read and listen to safety instructions？

A．Before takeoff.

B．In an emergency.

C．Throughout the flight.

D．During landings.

第11题

As heart disease continues to be the number-one killer in the United States, researchers h

ave become increasingly interested in identifying the potential risk factors that trigger heart attacks. High-fat diets and "life in the fast track" have long been known to contribute to the high incidence of heart failure. But according to new studies, the list of risk factors may be significantly longer and quite surprising.

Heart failure, for example, appears to have seasonal and temporal patterns. A higher percentage of heart attacks occur in cold weather, and more people experience heart failure on Monday than on any other day of the week. In addition, people are more susceptible to heart attacks in the first few hours after waking. Cardiologists first observed this morning phenomenon in the mid-1980, and have since discovered a number of possible causes. An early-morning rise in blood pressure, heart rate, and concentration of heart stimulating hormones, plus a reduction of blood flow to the heart, may all contribute to the higher incidence of heart attacks between the hours of 8:00 AM and 10:00 AM.

In other studies, both birthdays and bachelorhood have been implicated as risk factors. Statistics reveal that heart attack rates increase significantly for both females and males in the few days immediately preceding and following their birthdays. And unmarried men are more at risk for heart attacks than their married counterparts. Though stress is thought to be linked in some way to all of the aforementioned risk factors, intense research continues in the hope of further comprehending why and how heart failure is triggered.

What does the passage mainly discuss？

A．Risk factors in heart attacks.

B．Seasonal and temporal patterns of heart attacks.

C．Cardiology in the 1980s.

D．Diet and stress as factors in heart attacks.
