Algorithms (算法) affect nearly every part of a person's experience on the Internet. Search engines are most people' s entry to the Internet.If a person wants to find information about something, they usually start with a search bar.As soon as they start typing or choosing links,the algorithm starts gathering data about every choice users make and uses that data to try to find the websites or information that most directly relate to what the user is looking for.

The problem with algorithm is that they can limit the kinds of information people see,says MacMillan,a reading researcher with Project Information Literacy (能力). He argues this can be harmful to people's critical thinking and lead them to believe that only one point of view is correct.

Companies also pay to post advertisements for products that could relate to users' search data. For example,if you search for places to take a vacation,you will likely start to see ads for travel companies, flights or hotels.

Renee Hobbs, director of the Media Education Lab at the University of Rhode Island, however, argues that algorithms are not all bad. She says search engine algorithms can help you find what might be the most useful information faster. But she says it is in the interests of Internet companies to keep users on the Internet for as long as possible so they see more ads.

The current generation of young people grow up using the Internet and they are prone(易于遭受) to distrustful information.That is why schools must train students how to use the Internet more wisely in their Studies.It is the duty of education to keep students informed about the world around them. Yet it is not the duty of education alone. And lawmakers should consider increasing data protection rules. Individuals can also use a wide variety of websites to avoid algorithmic controls.

1.How do algorithms affect users' Internet experience?

A.They lead to slower Internet connection.

B.They block ads for users automatically.

C.They always help users get reliable links.

D.They determine the content users receive.

2.What is Hobbs' attitude to algorithms?

A.Doubtful. B.Supportive.

C.Objective. D.Indifferent.

3.What can be concluded from the last paragraph?

A.Young people fall victim to the Internet.

B.Data protection rules are already enough.

C.Education is fully responsible for algorithmic controls.

D.Joint efforts are needed to handle algorithmic controls.

4.Which column of a magazine is the text most likely from?

The health and welfare of every person in America will be affected by global warming, especially children, the elderly and the poor, according to a new White House science report.

The report said every region (地区) of the country will suffer worse health from heat waves and drought. All but a handful of states would have worse air quality and flooding. It predicts an increase in diseases spread by tainted (腐烂的) food, bad water and bugs (臭虫).

The report concludes that climate change causes real risk to human health and human system that supports the way of life in the United States.

Man-made global warming is caused by greenhouse gases from the burning of fossil fuels. At current emission (放射) levels, global temperatures are likely to rise by about 2 degrees by midcentury and about 7.5 degrees by the end of the century.

The most vulnerable (脆弱的) Americans — the poor, elderly, sick, very young and immigrants — will suffer more. That’s at least 10 percent of the country’s population, probably more. It will be tougher for these people to get enough health care for climate-related illnesses, to cool down in heat waves, to escape extreme events such as Hurricane Katrina, and even to get enough food.

While every region of America is vulnerable to global warming’s health and welfare effects, more people are moving to coastal regions, which are most vulnerable to climate change because of drought and hurricanes.

1.According to the report, we learn all of the following will risk human’s health EXCEPT ______.

A. heat waves and drought

B. increase in the number of bugs

C. reduction in carbon dioxide emissions

D. global warming and climate change

2.What does the underlined sentence in Paragraph 2 mean?

A. All of states would suffer flooding.

B. Air quality in few states is not high.

C. About half of all states would have clear air.

D. Flooding would occur in almost all the states.

3. Which of the following is NOT true according to the passage?

A. Global warming is caused by human beings.

B. It is wise for the Americans to move into coastal regions.

C. Global temperatures are increasing year by year because of carbon dioxide.

D. At least one tenth of Americans are more likely to suffer climate-related illnesses.

4. The writer wrote this passage to ______.

A. explain how the phenomenon of global warming forms

B. protect the vulnerable Americans from suffering from diseases

C. provide evidence that global warming and climate change risk human’s health

D. warn every American of the danger of global warming to their health

Neatness and personal cleanness have been around for ages and have become an important part of everyone’s daily routine. You might think that all modern societies would have the same neatness and personal cleanness practices. After all, doesn’t everybody take baths? Most people do recognize the need for cleanness, which is the basis for health. Neatness practices include all the little things people do to make themselves look their best, such as combing their hair and putting on makeup. However, while most modern people agree that these things are important, people in different cultures take care of themselves in different ways.

There used to be an old joke in America that people should take a bath once a week, whether they need one or not. In fact, though, Americans generally take a bath or more commonly, a shower every day. But in contrast to some cultures, most Americans get their shower in the morning so that they can start the day fresh. Americans are known for having very sensitive noses. In America, body smell is socially unacceptable. For that reason, Americans consider it a must to use special lotion (浴液) to prevent the smell. Ladies often add a touch of perfume. Men may spray on after – shave cream or manly – smelling perfume.

Some of the cultural varieties in neatness practices result from physical differences between races. Whereas many Asian men have little facial hair, Westerners have a lot. As a result, most American men spend some time each day shaving or tidying their facial hair to keep it nice. American women, on the other hand, generally prefer not to be hairy at all.

　Americans put great value on both neatness and personal cleanness. For some people, taking care of themselves has become almost a religion. As the old saying goes, “Cleanness is next to godliness.” Whether or not being clean and neat – looking brings one closer to God, it certainly at least brings one closer to others. Americans look down on people who don’t take care of themselves, or who “let themselves go.”

68．We can infer from the first paragraph that ________.

A．everyone takes baths daily to get a nice look.

B．people have the same neatness practices today.

C．neatness practices may be affected by cultures.

D．neatness means combing hair and doing makeup.

69．Americans have a bath in the morning to ________.

A．begin an energetic day                                  B．refresh their sensitive noses

C．prevent their body smell                               D．style their hair at home

70．According to the author, physical differences between races can cause differences in ________.

A．cultures                   B．locations                  C．religions                   D．neatness practice

71．The underlined phrase in the last paragraph means “________”.

A．care much about themselves                      B．give loose to themselves

C．stay away from other people                       D．stay closer to other people

Health and climate scientists have mapped how climate change affects different parts of the world in different ways. The scientists point to the fact that changes in the past thirty years may, have been affecting human health. Possible effects include more deaths from extreme(极度的) heat or cold, more storms and more crop failures in dry periods.

The health and climate scientists recently estimated(估计) that climate changes caused by human activity lead to more than one hundred and fifty thousand deaths each year. Cases of sickness are estimated at five million. And the W.H.O. says the numbers could rise quickly by the year of 2003.

Jonathan Patz of an environmental institute led the study. Professor Patz points out that climate scientists connected global warming with the heat that killed thousands in Europe in August, 2003. But he says poor countries least responsible(对……负责) for the warming are most in danger from the health effects of higher temperatures.

Professor Patz says areas in greatest danger include southern and eastern Africa and coastlines along the Pacific and Indian oceans. Also, large cities experience what scientists call a "heat island"effect that can make conditions worse.

Representatives(代表) from about two hundred countries hold a meeting in Canada, to discuss climate change. The ten-day meeting ends on December 9th. It is the first such United Nations meeting since the Kyoto Protocol(京都议定书) took effect earlier this year. The agreement aims to reduce the amount of carbon dioxide(二氧化碳) and other heat-trapping(吸热的) gases sent off into the air.

Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes are brought about by new technology are often mistaken for a change in attitudes.

An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be “very” or “somewhat” overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today’s parents are trying to manage their children’s lives past the point where this behavior is appropriate.

However, greater parental involvement does not necessarily indicate that parents are failing to let go of their “adult” children.

In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents’ involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible?

Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn’t present a generation ago? Many studies show that older parents—today’s grandparents—would have called their children more often if the means and cost of doing so had not been a barrier.

Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

1.The surveys inform us of______.

A. the development of technology

B. the changes of adult children’s behavior

C. the parents’ over-protection of their college children

D. the means and expenses of students’ communication

2. The writer believes that__________.

A. parents today are more protective than those in the past

B. the disadvantages of new technology outweigh its advantages

C. technology explains greater involvement with their children

D. parents’ changed attitudes lead to college children’s delayed independence

3.What is the best title for the passage?

A. Technology or Attitude

B. Dependence or Independence

C. Family Influences or Social Changes

D. College Management or Communication Advancement

4.Which of the following shows the development of ideas in this passage?

By choosing to let go of the past, we sweep out all the ashes that weigh us down and affect every aspect of our health, and our peace of mind.

My friend Jean was divorced after a thirty-year marriage that produced three daughters, one son and eight grandchildren. Because she actually raised them single-handedly, Jean was hurt and angry that the children didn't take her part after the divorce. For months she refused to attend any family celebration to which her former husband Jim was invited. When I reasoned that her children’s understanding of the relationship with and between the parents was probably altogether different from hers, she stuck to the belief that she was right.

One day Jean called in tears. “Saturday is my granddaughter's birthday, and I want to be with her, but I can’t bring myself to face my former husband.”  “Jim isn't the problem,” I said gently, “it's false pride. Instead of holding on to the painful past, which is over and done, let the feelings go and get on with your life. You're depriving yourself of the joy of sharing in these important occasions, while Jim feels free to experience them. Tell me, would you rather be right, or be happy?”

That must have done the trick because when Saturday arrived, Jean appeared at her daughter's home carrying her famous chocolate-chip cookies and a beautiful birthday

cake.

How great it feels to let go! And the more we practice the art of letting go of all negativity, the better able we become to devote our thoughts, our time, and our energy to living joyfully in the present, what ever age we happen to be.

1. It can be inferred that ____.

A. Jim did very little to bring up the children during their marriage.

B. The writer thought Jean and Jim shouldn't have divorced.

C. The children were on their father's side and didn't invite Jean to any family celebration.

D. Jean had been too tough on Jim before they divorced.

2.The underlined phrase “depriving yourself of” is closest in meaning to ____ .

A. persuading yourself to get              B. taking away from yourself

C. taking false pride of yourself            D. talking yourself into showing

3.In the writer's opinion, ____.

A. Jean and Jim should be remarried

B. a broken family could live together in peace

C. to be happy is more meaningful than to be right

D. everyone should look into the future
