2020年职称英语考试《综合类》考试共65题，分为单选题。小编为您整理阅读判断分析5道练习题，附答案解析，供您备考练习。

1、Dyslexia
As many as 20% of all children in the United States suffer from some form of the learning disorder called dyslexia.
Experts on dyslexia say that the problem is not disease. They say that persons with dyslexia use information in a different way. One of the world's great thinkers and scientists, Albert Einstein was dyslexic. Einstein said that he never thought in words the way that most people do. He said that he thought in pictures instead. The American inventor Thomas Edison was also dyslexic. Dyslexia first was recognized in Europe and the United States more than 80 year ago. Many years passed before doctors discovered that persons with the disorder were not mentally slow or disabled. The doctors found that the brains of persons with dyslexia are different. In most people, the left side of the brain, the part that controls language is larger than the right side. In persons with dyslexia, the right’ side of the brain is bigger. Doctors are not sure what causes this difference. However, research has shown that dyslexia is more common in males that in females, and it is found more often in persons who are left-handed. No one knows the cause of dyslexia, but some scientists believe that it may result from chemical changes in a baby's body long before it is born. They are trying to find ways to teach persons with dyslexia. Dyslexic persons think differently and need special kinds of teaching help. After they have solved their problems with language, they often show themselves to be especially intelligent or creative.
The first cases of dyslexia in Europe were discovered less than a century ago.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题目中的关键词是专有名词Europe，我们很快在第2段第5行找到答案所在句。通过对比题目和答案所在句，我们发现从recognize—discover，more than 80 years ago—less than a century ago都属于同义改写，但唯一有差别的是文中提到的两个地方： Europe和 the United States在80多年前发现了读写困难症病例. 但题目中仅仅提到了Europe。对于这个问题，我们可以进行如下推理：设A= Europe，B=the United States，实际上这道题就变为一道推理题：如果A+B正确，那么A是否正确？实际上很简单：A+B成立（正确）的充分必要条件是AUB正确，即A正确或者B正确。经过这样的推理，我们知道该题的答案应为A。

2、The Race into Space
American millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth and eight days in space and from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space and looking back at earth is one of the most rewarding experiences a human being can have."
This kind of experience isn't cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "For me it was a life dream. It was a dream that began when didn't have any money," he told reporters.
On 30 April 2002, Mark Shuttleworth became the world's second space tourist. Shuttleworth is a South African businessman. At the age of twenty - eight, he also paid $ 20 million for the eight - day trip.
Both Tito and Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list for flights into space. The spaceship to take them doesn't exist yet.
Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it’s so expensive, only very rich people can go into space. They want space travel to be available to more people.
That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an island in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia and California, seven days in space, and a vacation in Tonga, for $2 million.
However, space flight is still very dangerous. Bill Readdy is NASA's deputy assistant administrator for space flight. He says that the chances of dying are about 1 in 500. Because of this, it may take time before space tourism really takes off. You might be able to go up, but will you come down?
Both Tito and Shuttleworth have climbed Mount Qomolangma.
【单选题】

4、African wild dog
Finding a babysitter while you go out to work is, for example, an inconvenience. For the African wild dog, one of the continent's most endangered carnivores （食肉动物), it's a matter of life and death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food and stay at home protecting the young.
The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution and unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, and the species is expected to go extinct within decades if the trend continues.
Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog's weakness lies in its social organization.
Within each pack of up to 20 adults and pups, only the dominant male and female breed. The remaining animals help raise the pups, cooperating to hunt prey and defend the kill from other carnivores.
Because pups can't keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions and hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey and to defend the kill. There is also one less stomach in which to carry food back to the den, and one more mouth to feed when they get there.
Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups and still spare a babysitter. But with smaller packs, either the hunting or the babysitting suffers, or the animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.
Field observations in Zimbabwe supported the model. Packs of five animals or fewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.
A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poor reproduction and low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " And deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London's Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.
The African wild dog has been endangered.
【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:答案的依据是第2段：在过去的一个世纪里，非洲野狗的数量急剧下降。如果这个势头继续下去的话，在数十年里，这个物种就会灭绝。因此题干的说法是正确的。
