W: Because he has to, legally I mean.
M: Exactly! In this case the reason is obvious, so we usually don't question it. But when the reason is not so obvious and especially when the behavior. could have negative consequences, we're more likely to feel a need to explain the catkins of the behavior. Social psychologists have a term for this, for the process of explaining the muses of behavior. It's called causal attribution. And one theory suggests there's a pattern in the way we go about attributing causes to people's behavior. According to this theory, there are two categories of reasons: internal factors and external factors. Again, Lisa, say you're driving down the road and all of a sudden some guy turns into the lane right in front of you, and you have to slam on your brake to avoid an accident. How do you react？

听力原文： One of the reasons for our success as a species is our ability to eat and thrive on a large variety of foods. Many animal species have become extinct or are on the edge of extinction partly because they lack this adaptability. They need to feed on a particular kind of plant or a particular kind of animal or insect. If this source of food is for any reason re- moved, then the animal concerned is unable to change to a different diet. Gradually it becomes extinct. We know that many animal species have died out, but so have some human species such as the early form. of mall that is called Neanderthal man. Perhaps part of the reason for his failure to survive was his lack of adaptability in diet. But modern man is almost entirely free from the limitation of any particular food requirements. We are able to survive on a wide variety of foods both animal and vegetable. For example, the Eskimos are almost totally meat eaters: seal, bear, whale meat and fish form. their whole diet; the Aborigines of Australia, living in dry desert regions, have learnt to survive by making use of forms of insect life as food to supplement their diet of fruits and roots. Men have learnt to survive in the deserts and in dense rain forests; they have learnt to raise domestic animals, which live at high altitudes so that they can inhabit the mountainous regions of the world like Tibet; and they have made the coconut their chief food on the Pacific islands.
(30)
A．It is all ability both man and animals possess.
B．It is the reason for man's superiority over animals.
C．It is one of the reasons for man's success as a species.
D．It is a proof of our superior intelligence.
听力原文： At present, human beings have used many devices to measure time. Perhaps, the sundial was, one of the earliest and simplest devices. A sundial can measure the movement of the sun across the sky each day.
The sundial worked very well only when the sun was shining. So other ways of measuring the passing of time were invented at that time. One device was the hourglass. It used a thin stream of falling sand to measure time.
By the 1700s, people had already developed mechanical clocks and watches. And today many of our clocks and watches are electronic.
So we have devices to mark the passing of time. But what time is it now？ Clocks in different parts of the world do not show the same time at the same time. As international communications and travel grew, it became clear we need a way to establish a common time for all parts of the world.
In 1884, an international conference divided the world into 24 time areas or zones. Each zone represents one hour. The astronomical observation in Greenwich, England, was chosen as the starting point for the time zone.
Most people have no trouble in agreeing that time moves forward. Some scientists believe there is one reason why time moves forward. It is clear we need a way to establish a common time for all parts of the world with scientific law: the second law of thermodynamics. The law says disorder increases with time.
(33)
A．It measures the length of a day and a night.
B．it measures the movement of the sun each day.
C．It measures the passing of hours, minutes and perhaps seconds.
D．It measures the shadow of the stick across the flat surface of the sundial.
