听力原文： London taxi drivers know the capital like the back of their hands. No matter how small and indistinct the street is, the driver will be able to get you there without any trouble. The reason that London taxi drivers are so efficient that they have all gone through a very tough training period to get a special taxi driving license. During this period which can take from two to four years, the would-be taxi driver has to learn the most direct road to every single road and to every important building in London. To achieve this, most learners go around the city on small motorbikes, practising how to move to and from different points of the city. learner taxi drivers are tested several times during their training period by government officers. Their exams are terrible experiences. The officers ask you, "How do you get from Buckingham Palace to the Tower of London？" And you have to take them there in a direct line. When you get to the tower, they won't say "Well done." They will quickly move on to the next question. After five or six questions they would just say: "See you in two months' time." And then you know the exam is over.
Learner drivers axe not allowed to work and earn money as drivers. Therefore many of them keep their previous jobs until they obtain their license. The training can cost quite a lot because learners have to pay for their own expenses on the tests and medical exam.
(33)
A．Because they have a driving license.
B．Because they have received special training.
C．Because the traffic conditions in London are good.
D．Because the traffic system of the city is not very complex.

A public good is one that a person can use without reducing the use of it for another person. One of the best example of a public good is national defense. One person can benefit form. our national defense without reducing another person's benefits. In fact, it is difficult to keep any person in our society from enjoying the benefits of national defense.
The market system does not work well in producing public goods. This is because a person who refuses to pay for a public good cannot be kept from using it. Suppose that the neighbors in a high crime area decide to hire a police force. Each neighbor, except Mrs. Smith, agrees to pay $100 a year for it. Mrs. Smith refuses to pay because she knows that if all the others pay the $100, the police will guard the area anyway. So Mrs. Smith can enjoy the services of the police force without paying $100.
The market system has no way to deal with this type of problem. For this reason, we cannot ask each person to make a direct payment in the form. of product price. Therefore, we collect money for public goods by using taxes.
According to the passage, public goods are______.
A．services enjoyed by all people
B．what we can buy and sell in public
C．products that we make for national defense
D．taxes paid by the people involved

Break-up
Once in a person's lifetime, everyone finds this one perfect person whom they fall hopelessly in love with and live happily with ever after. That is a mere fallacy. In the real world, this simply does not happen. Yes, people do have common interests and therefore develop romantic involvement, but it is basic common sense that these relationships have a life span and simply cannot last. Real life relationships are definitely more like "The Real World" rather than "Romeo and Juliet".
Romanticism is wonderful in itself, and thus two people can live in heavenly bliss, but it all must come to an end somehow. It is a fact of life that couples do break up, and there are many reasons why. There are countless reasons, ranging from cheating to abuse, attributing to breakups.
Wealth
One reason why couples might break up is money or a lack thereof. If one partner in a relationship is always paying or keeping up all the bills, his/her partner just might grow tired of it and decide that it is a valid reason to separate. For example, a woman who is always lending her boyfriend money for his rent, car note, and social expenses will probably eventually grow tired of it and leave him.
Addiction
More reasons why couples separate, addictions often result in ugly breakups. Whether it is an addiction to drugs, gambling, or whatever, hardly anyone would be willing to take that on an everyday basis. Most people would agree that it is not pretty to see someone throw their life away on addictions. It is simply not attractive and thus, not many people would want to be with someone with an extreme problem like that.
Physical Assets
An unfortunate reason for a breakup, physical disabilities, also occurs at times. This can range from a paralyzing accident to infertility. To some people, having children is the most important priority in their adult life. Having a partner who is unable to have children can very much hinder a relationship. Thus, it will not last. Likewise, having a partner who has a paralyzing disability might be too much for someone to take. Being with a person, who becomes handicapped, though unfortunate, is a big burden to place on a person.
Test of Time and Distance
Growing apart, an instance in which two people just do not feel attraction towards each other anymore is very commonplace, resulting in an end of a relationship. Some couples simply "fall out of love". Some people can only stand so much of another person before they grow tired of the situation. Also, it could be as a result to distance. For example, when a couple who were together in high school go their own ways in choosing colleges, this, more often than not, results in the couple breaking up. A long distance relationship like that simply does not work out often.
"I Want the Better."
In direct relation to growing apart, a person sometimes finds another person besides their boy/ girlfriend who they are attracted to. Finding somebody "better" will kill a relationship quickly, and start a new relationship, If a person finds someone more attractive than the person they are currently with, they might have to weigh their options and decide that they want to go another direction.
Cheating
Likewise, when a person finds someone they like, this could result in cheating, another reason why couples break up. If a guy catches his girlfriend cheating on him, or vice versa, this could very well be a valid reason to end that relationship. Finding someone cheating leads to a lack of trust and thus, kills the relationship.
Abuse
Also, another very serious reason resulting in a break-up is abuse. When someone abuses his or her girlfriend, spouse, or children, a break-up is definitely necessary. Someone who is taking abuse is playing with f
