题目内容

Social insects live in the form of societies which in some ways are similar to human societies. In both types of societies there is a division of labour. In insect societies certain insects have the duty of reproduction (繁殖); the workers collect food while the soldiers defend the land. In the same way human groups such as farmers and shopkeepers have specialized functions (作用) in producing goods and providing services to the society.

Insects and human societies are also alike in that individual (个体的) members of the society work together. White ant workers work together to build nests. Similarly, in human societies engineers, architects (建筑师), town planners and construction workers unite to build cities.

The nests of social insects are as complex (复杂的) as a man-made city. In some insect nests special places are provided for the young and for food storage. Many nests also have devices for regulating the temperature. So insect nests are as functional as human houses.

It is not surprising, therefore, that many similarities have been made between social insects and human societies. It must not be forgotten, however, that insect social behavior is determined by nature. Insects show no ability for learning or for developing a social tradition based on learning.

64. Mentioned in the passage, the functions performed by social insects are ________.

A. reproduction, collecting food and building nests, etc.

B. reproduction of food, defending the land and building nests, etc.

C. producing food, defending the land and nursing babies, etc.

D. reproduction of food, providing services and defending the land, etc.

65. The second paragraph tells us that ________.

A. engineers, architects, town planners and construction workers don't have to work together to build a city

B. white ant workers work together in the same way as nurses do

C. in both societies there is social co-operation (合作)

D. white ant workers unite in order to defend the land

66. Human and insect societies are different in that ________.

A. different groups have different traditions

B. insect social behavior is determined by nature while human societies have developed a social tradition based on learning

C. human beings can make many similarities

D. human beings can make machines while insects can't

67. The main idea of this passage is ________.

A. the similarities between social insects and human societies

B. the complex nests of social insects

C. the functions performed by social insects

D. the cause of insect social behavior

Despite all the reports of Internet security attacks over the years, including the recent ones on Google’s e-mail service, many people have reacted to the break-ins with a shrug (耸肩).

Mr. Shulman and his company examined a list of 32 million passwords that an unknown hacker（黑客） stole last month from Rock You, a company that makes software for users of social networking sites like Facebook and MySpace. The list was briefly posted on the Web, and hackers and security researchers downloaded it.

The list provided an unusually detailed window into computer users’ password habits. Typically, only government agencies like the F.B.I. or the National Security Agency have had access to such a large password list.

Some Web sites try to keep back the attackers by freezing an account for a certain period of time if too many incorrect passwords are typed. But experts say that the hackers simply learn to trick the system, by making guesses at an acceptable rate, for instance.

To improve security, some Wed sites are forcing users to mix letters,numbers even symbols in their passwords. Others, like Twitter, prevent people from picking common passwords.

Still, researchers say, social networking and entertainment Web sites often try to make life simpler for their users and are unwilling to put too many controls in place.

Even commercial sites like eBay must weigh the consequences of freezing accounts, since a hacker could, say, try to win an auction（拍卖） by freezing the accounts of other potential buyers.

But owing to the reality of our overcrowded brains, the experts suggest that everyone choose at least two different passwords— a complex one for Web sites where security is vital, such as banks and e-mail, and a simpler one for less risky places, such as social networking and entertainment sites.

Mr. Moss relies on passwords at least 12 characters long, figuring that those make him a more difficult target than the millions of people who choose five-and six-character passwords.

“It’s like the joke where the hikers run into a bear in the forest, and the hiker that survives is the one who outruns his companions,” Mr. Moss said. “You just want to run that bit faster.”

The underlined sentence “Many people have reacted to the break-ins with a shrug” shows that many people .

A.don’t take seriously the hacker’s break-ins

B.are worried and frightened at the hacker’s break-ins

C.don’t know what to do with the hacker’s attacks

D.are eager to get helps from the experts

It’s not uncommon in America for a person to belong to some kind of volunteer group. Donating one’s time and services is very much a part of the American way of life. Most charitable activities are organized by churches and groups around the nation and even encouraged by the government. The helping hand is extended to the poor， the homeless and the disabled. Some people work to teach youngsters how to read. Others open up soup kitchens to feed the homeless. Volunteers also take care of the disabled by making reading tapes for the blind and working in orphanages（孤儿院）to help children without parents.
High school students are often encouraged to become volunteers and many school club activities center around volunteer services. Students may work with disabled children during a summer program， or participate in a club activity which helps to bring meal to senior citizens who are shut-ins. With their sense of idealism（理想主义）students are often eager to donate their spare time. They see such activities as a way of becoming involved in the community and the adult-world. Social action for them becomes as important as their academic studies.
In a like manner， throughout the year，fund raising drives are also conducted by schools and community groups to raise money for a worthy cause. They may respond to a recent earthquake in a foreign country， a flood somewhere within their own， or another natural disaster which has left people destitute and homeless. They may organize drives to collect food， clothing and medicines to serve an immediate need. Today even the Halloween custom of ‘trick or treat’has become an occasion to collect money for a charitable cause.
The motive to help those less fortunate comes from the poor origins of the American nation. Those immigrants who were poor and downtrodden（受压迫的）became dependent on the kindness of their neighbors to make a new life for themselves.
American volunteers work throughout the world in less developed countries. They volunteer by serving as a champion of goodwill both at home and abroad， which no doubt enriches both his life and those whom he serves.
