[问题]
道路施工正值雨期,土基、基层、面层如何控制质量?
雨期施工,沟槽怕泡槽,回填怕含水量过高,土基和基层怕含水量过高、怕达不到压实度,沥青面层施工怕有水作业。所有这些的根源就是雨水,为此,该工程雨期施工的质量控制的核心是防雨、挡水、排水。此案例应从以下几方面分析:
(1)根据雨期施工特点,做好施工组织设计,做到思想重视,物质准备充分,组织健全。掌握天气预报和施工主动权,是在雨水侵袭干扰的间隙中控制质量、完成工程的基础。
(2)要从采取防、排水措施入手,准备好施工方案和组织与器材,来考虑雨季施工的质量控制。
(3)应注意沟槽回填和处理土基施工要集中力量安插在无雨的时段,施工一段完成一段。尽量当天拌完、铺完,连续作业,一气呵成。土基施工要留有一定横坡,以利排水。
(4)该工程为城市道路,施工无机结合料稳定材料,一定要求厂拌,注意防雨,严格检验含水量以及施工时快节奏安排,做一段完一段。
(5)应抓住沥青面层需在无水条件下施工才能保质量的关键,据天气预报安排面层沥青混合料施工。施工时若下层潮湿,应晒干后再铺上一层。缩短施工长度,力争摊铺一段、碾压一段、完成一段。其间加强与沥青拌合厂联系。遇大雨时,应尽快将已铺完的压实,未铺的料应遮盖,不再施工。

Passage 3
Questions 11 to 15 are based on the following passage:
Unlike their American or European counterparts, car salesmen in Japan work hard to get a buyer. Instead of lying lazily around showrooms waiting for customers to drop by, many Japanese car salesmen still go out to get them. They walk wearily along the streets cars door-to-door. New customers are hunted with fruit and cakes on their birthdays. But life is getting tough, and not just because new-car sales are falling.
With more Japanese women (who often control the household budget) going out to work, the salesmen increasingly find nobody at home when they call. That means another visit in the evening or the weekend. Then they face an extra problem: more people, especially the young, prefer to choose a new car from a showroom where they can compare different models.
Even as late as the mid-1980s some 90% of new cars were sold door-to-door. In some rural areas most new cars are still sold this way. But in the big cities more than half the new cars are now sold from showrooms.
Although investing in showrooms is expensive because of the high cost of Japanese land, dealers have little choice. A labor shortage and higher among Japan’s workforce are making it difficult to hire door-to-door salesmen. Most of a Japanese car salesman’s working day is spent doing favors for customers, like arranging insurance or picking up vehicles for servicing, rather than actually selling.
Japan’s doorstep car salesmen are not about to vanish. The personal service they provide is so deep-rooted in Japan that they are likely to operate alongside the glittering new showrooms. The two systems even complement each other. What increasingly happens is that the showroom attracts the interest of a potential buyer, giving the footsore salesmen a firm lead to follow up with a home visit.

A. they sell cars door-to-door
B. they buy presents for their customers
C. they enjoy themselves in recreation centers

A. light B. moderate C. fierce D. unfair
13. Young people like to buy a new car .

C. made in the U.S.A. D. made in Japan
14. The squadron of Japanese car salesmen is reducing because of .
A. a labor shortage

C. high cost land
D. both A and B
15. Japanese car salesmen to their customers many favors such as .

What makes a child speak a language has long been a puzzle to linguists. 61 speaking, there are two schools of linguists, both of whom try to explain 62 a child picks up a language so easily. The fact that a child picks a language 63 is 64 : At one year old, a child is able to say “bye-bye”; at two, he is able to use fifty; by there he begins to 65 tenses. The famous American linguist Noam Chomsky 66 that human being have a sort of built-in system for language use, and that the 67 is 68 . Children are not taught language 69 they are taught arithmetic. Other linguists, 70 , hold the view that a child learns 71 of his language from the hints in the environment. 72 , theorists of both schools 73 that there is a biological basis for language use. The 74 is which is more important, the inner ability or the environment. This is certainly a field 75 to be explored. Researchers from both schools are busy finding evidence to 76 their own theory, but 77 side is persuading the other.
It seems that in order to 78 why a child learns a language so easily, we have to 79 the joint efforts of both schools. Some linguist, like De Villiers, has recognized the value of cooperation, and 80 linguists of both sides to work together.

Passage 2
Questions 6 to 10 are based on the following passage:
The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown tat 40 percent of cancer is related to the diet as well, especially cancer of the colon. Different cultures ate more prone to get certain illnesses because of the food that is characteristic in these cultures. That food is related to illness is not a new discovery. In 1945, government researchers realized that nitrates and nitrites, commonly used to preserve color in meats, and other food additives, caused cancer. Yet these carcinogenic additives remain in our food, and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful. The additives that we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to control these procedures, the practices continue.
6. How has science done a disservice to mankind?
A. Because of science, most of the foods we eat today are contaminated.
B. It has caused a lack of information concerning the value of food.
C. As a result of scientific intervention, some potentially harmful substances has been added to our food.
D. The scientists have preserved the color of meats, but not of vegetables.
7. What are nitrates used for?
A. They preserves flavor in packaged foods.
B. They preserve the color of meats.
C. They are the objects of research.
D. They cause the animals to become fatter.
8. The FDA has tried repeatedly to control .
A. the attempt to fatten the animals
B. the attempt to cure sick animals
C. the using of drugs to animals
D. the using of additives to preserve the dolor of food
9. The word “carcinogenic” means most nearly the same as .
A. trouble-making B. color-retaining
C. money-saving D. cancer-causing
10. Which of the following statements is NOT true?
A. Drugs are always given to animals for medical reasons.
B. Some of the additives in our food are added to the food itself and some are given to the living animals.
C. Researchers have known about the potential hazards of the food additives for over thirty-five years.
D. Food may cause forty percent of cancer in the world.
