2020年职称英语考试《综合类》考试共65题，分为单选题。小编为您整理概括大意与完成句子分析5道练习题，附答案解析，供您备考练习。

1、Geology and Heap
(1)The importance of particular metals in the human diet has been realized within the past few decades, and the idea that geology might be related to health has been recognized for a number of elements such as iodine, zinc and selenium. For example, soils with low iodine contents produce crops, and animals deficient in iodine. A lack of iodine in the human diet leads to some serious diseases.
(2)The ultimate source of metals within the human body is rocks, which weather into soil, gaining or losing some of their chemical constituents. The crops we eat selectively remove from the soil the elements that they require for growth. The water we drink contains trace elements leached from rock and soil. Thus the geology and geochemistry of the environment have effects on the chemistry and health of plants, animals and people.
(3)So far there is no data to suggest that people living on metal-rich soils experience a potential health hazard. The levels of metals within naturally contaminated soils are generally not high enough to cause serious health problems. Living on metal-rich soils does not represent a health risk unless large quantities of soil are digested or metal-rich dust is inhaled. However, small children are particularly exposed to metal-rich topsoil in playgrounds and gardens. They are also the most likely ones to eat potentially dangerous metal-rich soil.
(4)Heavy metals are persistent: they do not break down to other chemicals in the environment. Industrially polluted sites usually undergo intensive clean-up and rehabilitation because heavy metals are a health concern once they enter the food chain. Some trace metals are alleged to cause cancer and are also known to cause poisoning
(5)In contrast, naturally contaminated soils have not been subject too risk assessment studies and rehabilitation measures, despite the fact that they frequently possess metal concentrations well above those of such polluted by humans and above environmental quality criteria.
(6)There is a vital need to understand the potential risks and long-term health effects of living on naturally contaminated soils. Future environmental investigations of naturally polluted soils should concentrate on the potential pathways of metals into the food chain and human body. Geologists should be part of such studies as they can provide the essential background information on rock and soil chemistry as well as the chemical forms of heavy metal pollution.
It is extremely necessary to study the long-term effects caused by living on____ .

正确答案:C

答案解析:本题答案的依据是最后一段的第1句，即“There is a vital need to understand the potential risks and long-terse health effects of living on naturally contaminated soils. ”

1、Intelligent Machines
1. Medical scientists are already putting computer chips (芯片) directly into the brain to help people who have Parkinson's disease, but in what other ways might computer technology be able to help us? Ray Kurzweil is author of the successful book The Age of Intelligent Machines and is one of the world's best computer research scientists. He is researching the possibilities.
2. Kurzweil gets computers to recognize voices. An example of this is Ramona; the virtual (虚拟的) hostess of Kurzweil's homepage, who is programmed to understand what you say. Visitors to the site can have their conversations with her, and Ramona also dances and sings.
3. Kurzweil uses this technology to help people with physical disabilities. One of his ideas is a "seeing machine". This will be "like a friend that could describe what is going on in the visible world", he explains. Blind people will use a visual sensor (探测器) which will probably be built into a pair of sunglasses. This sensor will describe to the person everything it sees.
4. Another idea, which is likely to help deaf people, is the "listening machine". This invention will recognize millions of words and understand any speaker. The listening machine will also be able to trans late into other languages, so even people without hearing problems are likely to be interested in using it.
5. But it is not just about helping people with disabilities. Looking further into the future, Kurzweil sees a time when we will be able to download our entire consciousness onto a computer. This technology probably won't be ready for at least 50 years, but when it arrives, it means our minds will be able to live forever.
Ramona is able to understand ____.
【单选题】

A.what you say

B.a pair of sunglasses

C.the listening machine

D.a visual sensor

E.who have disabilities

F.living forever in a computer

1、Robots
The most sophisticated (先进的) Japanese robots, which have vision systems and work at very high speeds, are still based on American designs. Studies of robots, particularly computer control software, are considered to be generally less advanced in Japan than in America or Europe.
Although industrial robots were originally developed as devices for simply handling objects, today their commonest uses are for more skilled work like welding (焊接), spray-painting and assembling components.
In Britain robot sales appropriately peaked in 1984, but have been declining ever since. This is partly because British wage rates are too low to make robots financially attractive and partly because engineers now have more experience with robots and are more aware of the difficulties of introducing them effectively.
It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job.
It is estimated that 20% of all comic book heroes in Japan are robots. This is an enormous number because comics are so popular that they make up a third of all material published in Japan.
The reliability of robots is measured in their MTBF or mean time between failures. This has risen from about 250 hours in the mid-1970s to about 10,000 hours today (equivalent to working 18 hours a day for two years). One way robot manufacturers have increased reliability is to test every single component they buy, instead of the normal procedure of just testing a small .sample.
The biggest single benefit of introducing robots claimed by Japanese companies is that they increase quality control. One programmed robots can work more accurately and consistently than humans, who can get tired and bored.
One disadvantage of using robots is that they consume________.
【单选题】

A.too much energy

B.based on American designs

C.they are too costly

D.they are not reliable

E.quality control

F.free of charge

正确答案:A

答案解析:首先根据语法知识，及物动词consume后加名词作宾语，排除选项B、C、D。consume作动词表示“消耗”，剩余选项中只有A选项“too much energy”可以与其搭配。此外，文章第四段It has been calculated that a robot uses on average about 100 times more energy than a human to do an equivalent job也表明：做同样的工作，机器人平均要消耗的能量是人类的100多倍。由此可以肯定A为正确答案。

1、Ford
(1)Ford's great strength was the manufacturing process not invention. Long before he started a car company, he was a worker, known for picking up pieces of metal and wire and turning them into machines. He started putting cars together in 1891, although it was by no means the first popular automobile, the Model T showed the world just how creative Ford was at combining technology and market.
(2)The company's assembly line alone. threw America's Industrial Revolution into overdrive(高速运转）. Instead of having workers put together the entire car, Ford's friends, who were great toolmakers from Scotland, organized teams that added parts to each Model T as it moved down a line. By the time Ford' s Highland Park plant was humming (嗡嗡作响) along in 1914, the world's first automatic conveyor belt could turn out a car every 93 minutes.
（3）The same year Henry Ford shocked the world with the $5 a day minimum Wage scheme, the greatest contribution he had ever made. The average Wage in the auto industry then was $2. 34 for a9-hour shift. Ford not only doubled that he also took an hour off the workday. In those years it was unthinkable that a man could be paid that much for doing something that didn't involve an awful lot of training or education. The Wall Street Journal called the plan "an economic crime" and critics everywhere laughed at Ford.
(4)But as the wage increased later to daily $10, it proved a critical component of Ford's dream to make the automobile accessible to all The critics were too stupid to understand that because Ford had lowered his costs per car, the higher wages didn't matter, except for making it possible for more people to buy cars.
Ford was the first to adopt ____
【单选题】

A.criticized by the media

B.the low wage in the auto industry

C.own a car

D.Produce cars in large numbers

E.the 8-hour-shift practice

F.combined technology and market

正确答案:E

答案解析:第3段讲到，当时汽车工业实行的是9小时工作制，平均每小时2. 34美元。Ford不仅把工资翻了番，而且还把工作日中的工作时数去除了一小时。也就是说，Ford是第一个实行8小时工作的人。
