The "cloud war" is taking place as the dispute between the United States and China about data hacking and computer network security grows stronger. Chinese companies such as Alibaba, Baidu and Huawei are expanding within their country and gaining customers in other countries. They are creating data centers in multiple countries and trying to sell data management services throughout the world.

The increasing competition in cloud computing and storage incurs the new challenge and worries some experts. They are concerned about the safety of data. After all, companies often use the cloud to store important, confidential information and to operate such activities as data-driven machinery, telecommunications, banking and transport systems — including plans for driverless vehicles.

Lee Branstetter is an associate professor of economics at the Heinz School of Policy and Management of the Carnegie Mellon University. He told many multi-national companies "have serious concerns about the protection of their intellectual property （知识产权）."Branstetter said some of these large companies already believe they have lost valuable information.

Sheila Jasanoff is the director of the program on science, technology and society at Harvard's Kennedy School. She called the cloud computing industry "unruly". In other words, the industry is not strictly governed.

"People （in the business） are making rules as they go along or taking advantage of the lack of rules," Jasanoff said. She said cloud computing companies are not clear about what security measures they are promising customers. She is worried that a major accident may happen before governments realize the need for stronger rules in the cloud computing industry. She believes there should be internationally-accepted rules to meet the new challenge. But she does not believe an international agreement will be reached anytime soon.

1.What does the "cloud war" refer to?

A.The war up in the sky.

B.Some kind of cold war.

C.The China-US relationship.

D.The competition on the "cloud".

2.What concerns some experts according to Paragraph 2?

A.Information security.

B.Wars among countries.

C.The storage of “cloud”.

D.The lack of technology.

3.Which of the following may be consistent with Jasanoff's opinion?

A.A major accident is bound to take place soon.

B.An agreement is to be reached in the near future.

C.The cloud industry needs guiding and monitoring.

D.Governments have kept an eye on cloud industry.

4.What is the best title for the text?

A.China's Rise or Not

B.New War, New Challenge

C.Chances on Cloud Information

D.Growth of Cloud Computing Industry

Life expectancy in the United States has been in decline for the first time in decades, and public health officials have identified a series of potential causes, including inaccessible health care, rising drug addiction and rates of mental health disorders, and socio-economic factors. Now, a study led by the Yale School of Medicine has attempted to find out the relative impact of two factors most often linked to life expectancy – race and education – by looking at data about 5,114 black and white participants in four U.S. cities.

The lives and deaths among this group of people – who took part in the study approximately 30 years ago when they were in their early 20s – show that the level of education, and not race, is the best predictor of who will live the longest.

Among the 5,114 people followed in the study, 395 had died. These deaths were occurring in working-age people, often with children, before the age of 60. The rates of death among participants in this group did clearly show racial differences, with approximately 9% of blacks dying at an early age compared to 6% of whites. There were also differences in causes of death by race. For instance, black men were significantly more likely to die of murder and white men from AIDS. The most common causes of death across all groups over time were cardiovascular disease and cancer.

But there were also obvious differences in rates of death by education level. Approximately 13% of participants with a high school degree or less education died compared with only approximately 5% of college graduates.

Strikingly, when looking at race and education at the same time, the researchers found that differences related to race almost disappeared: 13.5% of black subjects and 13.2% of white subjects with a high school degree or less died during the course of the study. By contrast, 5.9% of black subjects and 4.3% of whites with college degrees had died.

Therefore, improving overall quality of education is something tangible that can help reverse (扭转)this troubling trend in reduction of life expectancy among middle-aged adults.

1.What can we learn about the participants in the study?

A.The whites are more aggressive.

B.The whites got higher education.

C.More blacks than whites died young.

D.More whites than blacks died of cancer.

2.Compared with education, the influence of race on death rates is 　　　　　 .

A.significant B.unnoticeable

C.growing D.long-lasting

3.What does the underlined word “tangible” probably mean?

A.Realistic. B.Creative.

C.Challenging. D.Temporary.

4.What can be inferred from the research findings？

A.People can get smart through learning.

B.One should not discriminate other races.

C.People don’t enjoy equal rights for education.

D.One can live longer by getting more education.

Stepfamilies are commonplace in the United States and their number continues to grow. While stepfamilies differ widely in their make-up， they all consist of a parenting couple and children， one or more of whom is of a previous union. Such combinations of his kids， her kids， and then， possibly， kids of the new union make for complicated and often trying difficulties， more challenging than those of traditional families.

Since stepfamilies involve more people and， consequently， more potential problems from the start than do childless new marriage， it is wise for the couple to do some careful planning prior to (＝before) marriage. Not only do the prospective(预期的) marital partners need agreement about their own carriers， life goals， finance and special interests， they must also prepare for new relationship with their children and attempt to accommodate their individual needs and feelings. Furthermore， there are often the rights of other relatives to consider.

As for any family， the basic ingredient(成分) of a successful stepfamily are affection， kindness and mutual(相互的) respect. However， love alone is not enough. Certainly love is the cornerstone upon which the foundation of any family is built， but there are also many other important ingredients involved in building a successful stepfamily.

Surveys reveal that successful families regard the ability to communicate openly as the most important factor in their success. Communication is what keeps families on track and functioning as a unit. Although healthy communication is easier for some people than for others， this skill can be learned and improved. Healthy communication involves speaking clearly and listening carefully.

By their very nature， stepfamilies often are complicated by past events that give rise to ambivalent(矛盾的) loyalties， lingering(持久的) hurts， fears， feelings of guilt and unrealistic dreams. The difficulties that arise within the stepfamilies are human and understandable. However， there are ways to confront(面临) and resolve them. For example， support groups and professional counselors(法律顾问) are available in most communities to provide help and guidance when communications stopped and problems seem overwhelming(压倒性的).

Planning and building a stepfamily is not a responsibility to take lightly. It can be a very trying and， at times， seemingly impossible effort. Many potential troubles can arise and threaten to destroy the stepfamily. Nevertheless， meeting and mastering these special challenges can bring unexpected satisfactions and rewarding depths of family closeness and affection.

1.According to the passage， there are 　　　 in the United States.

A.no stepfamilies

B.more stepfamilies than ever before

C.fewer stepfamilies than ever before

D.fewer stepfamilies than traditional ones

2.Which of the following can help avoid the potential problems arising in a stepfamily？

A.The pursuit of the same careers.

B.Professional interventions(干涉).

C.The development of special interests.

D.Careful planning before the marriage.

3. Many people believe that 　　　 contributes most to the building of a successful stepfamily.

A.everlasting loyalties

B.open communication

C.kindness and mutual respect

D.persistent(持久稳固的) affection

4. It is natural for a stepfamily to be 　　　.

A.unrealistic

B.complicated

C.ambivalent

D.guilty

5.According to the author， planning and building a stepfamily is 　　　.

A.impossible
