Many women who battle breast cancer will tell you it's a life-changing experience. However, a new study shows that for many (51) , the changes aren't always positive or permanent.
Beth Snoke has watched her mother and both grandmothers battle and survive breast (52) So when she was diagnosed, there was no doubt in her mind (53) she had to do.
"I do exactly what the doctors say as far as the medicine that I'm on, as (54) as the vitamins, the diet, and the fitness. And I can't stress enough (55) important that is," says Beth Snoke. But a surprising new study shows that (56) every woman who beats breast cancer is getting that message. In fact, nearly 40% of them say even (57) surviving breast cancer, they haven't made significant changes in the (58) they eat or how much they exercise.
"Not all survivors are taking advantage of this teachable moment and making positive health changes in (59) life," says Electra Paskett, PhD, at Ohio State University's Comprehensive Cancer Center. Paskett says diet and exercise have been proven to not only help women feel better during and after treatment, they may (60) play a role in preventing some cancers from coming back (61) growing evidence, some women just aren't listening.
"Colon cancer survivors (62) exercise have actually been shown to have improved survival rates. So, yes, it is true that perhaps by making some of these healthy choices we can actually increase their health," says Paskett.
As a breast cancer survivor (63) , Paskett knows first hand how much difference diet and exercise can (64) The challenge, she says, is to get more survivors to be more like Beth, during and after treatment.
Experts say exercising more and eating a healthier diet can also cut (65) on stress and help women overcome depression. There are more than 2 million breast cancer survivors living in the U.S. Of those, nearly a million have yet to change their diet or exercise routines.

There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.
Another way is energy conservation (节能 ), which means using energy more efficiently (有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.
Finally, renewable energy sources are used even though they are often expensive to develop. One form. of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped (压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.
1、How many ways of dealing with the energy problem are discussed in the text? ()
A、Two.
B、Three.
C、Four.
D、Five.
2、From the text we learn that coal().
A、is quite easy to produce
B、is not used most efficiently
C、is the most common source of energy
D、could be renewed only by new technology
3、The writer tells about the "special houses" because they().
A、show the excellent skills of the builders
B、serve as an example of energy conservation
C、are heated by different sources of energy
D、are warmer than other types of houses
4、The underlined words "geothermal energy" in the third paragraph mean ().
A、renewable source
B、 underground source
C、 heat inside the earth
D、 temperature of the earth
5、At a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75 °C ? ()
A、One km.
B、 Two km.
C、 Three km.
D、 Four km

Some pessimistic experts feel that the automobile is bound to fall into disuse, They see a day in the not. too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is hem to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.
The motorcar will undoubtedly change significantly over the next 30 yearn. It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present types.
Regardless of its power source, the auto in the future will still be the main problem in mi)an traffic congestion. One proposed solution to this problem is the automated highway system.
When the auto enters the highway system, a retractable arm will drop from the auto and make contact with a mil, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The computer will then monitor all of the car's movements.
The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best mute, and reserve space for the car an the way to the correct exit from the highway. The driver will then be free to relax and wait for the buzzer that win warn him of his coming exit. It is estimated that au automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.
One significant improvement in the future car will probably be ______
A.its power source
B.its driving system
C.its monitoring system
D.its seating capacity

One of Microsoft's cool people, is Patrick Blackburn. As a test manager for the Product Group, Blackburn's job may sound routine; however, he says it's anything but that.
"Most people ,think of software testing as a mundane task of punching the keyboard like a monkey, trying to break the program," Blackburn says. "Part of that is true, but we write software programs called Monkeys to do that for us so that we don't have to hire real monkeys. Real monkeys are too difficult to manage and don't usually pass the personal hygiene criteria !" In reality, Blackburn says, testing responsibilities are very technically challenging and often include complete development cycles of their own. He spends most of his time coming up with creative incentives to convince his team to believe in schedules for products that don't yet exist, hiring great people to build strong teams, and pounding on the products to find bugs before the customer sees them.
According to Blackburn, the most critical thing you can do to succeed at Microsoft is to focus on what you believe is important. "It's easy to get overwhelmed with everything going on around you, so first and foremost you need to stay focused," he says. "What you focus on needs to be something you firmly believe in so that you'll pursue it and defend your mission with a passion. "
He also thinks that one of the biggest differences between his co-workers at Microsoft and those at his former workplace is the sense of ownership and the impact on the business that everyone shares. "We hire people who tend to become personally attached to the products and the success of the company, and the environment really perpetuates this," Blackburn says. "It's much easier to motivate a team at Microsoft than any other company I've been in. "
One of the most difficult parts of Blackburn's job is staying ahead of the people who report to him. "Because there are so many smart people and technology is changing so quickly, it is a constant challenge to keep up," he says. "I hope that's because I hire such great people!"
To succeed, Blackburn uses time management tactics and allocates a specific amount of time to education. "My personal goal is to spend at least 20 percent of my time learning new things through formal and informal methods. "
Patrick Blackburn thinks software testing is ______ .
A.a routine and mundane job
B.technically challenging
C.like a monkey punching keyboard
D.partly done by monkeys

Students of United States history, seeking to identify the circumstances that encouraged the emergence of feminist movements, have thoroughly investigated the mid-nineteenth century American economic and social conditions that affected the status of women. These historians, however, have analyzed less fully the development of specifically feminist ideas and activities during the same period.
Furthermore, the ideological origins of feminism in the United States have been obscured because, even when historians did take into account those feminist ideas and activities occurring within the United States, they failed to recognize that feminism was then a truly international movement actually centered in Europe. American feminist activists who have been described as "solitary" and "individual theorists" were in reality connected to a movement—utopian socialism—which was already popularizing feminist ideas in Europe during the two decades that culminated in the first women's rights conference held at Seneca Falls, New York, in 1848. Thus, a complete understanding of the origin and development of nineteenth century feminism in the United States requires that the geographical focus be widened to include Europe and that the detailed study made of social conditions be expanded to include the ideological development of feminism.
The earliest and most popular of the utopian socialists were the Saint-Simonians. The specifically feminist part of Saint-Simonianism has, however, been less studied than the group's contribution to early socialism. This is regrettable on two counts. By 1832 feminism was the central concern of Saint-Simonianism and entirely absorbed its adherent's energy; hence, by ignoring its feminism, European historians have misunderstood Saint-Simonianism. Moreover, since many feminist ideas can be traced to Saint-Simonianism, European historians' appreciation of later feminism in France and the United States remained limited.
Saint-Simonian's followers, many of whom were women, based their feminism on an interpretation of his project to reorganize the globe by replacing brute force with the rule of spiritual powers. The new world order would be ruled together by a male, to represent reflection, and a female to represent sentiment. This complementarity reflects the fact that, while the Saint-Simonians did not reject the belief that there were innate differences between men and women, they nevertheless foresaw an equally important social and political role for both sexes in their Utopia.
Only a few Saint-Simonians opposed a definition of sexual equality based on gender distinction. This minority believed that individuals of both sexes were born similar in capacity and character, and they ascribed male-female differences to socialization and education. The envisioned result of both currents of thought, however, was that women would enter public life in the new age and that sexual equality would reward men as well as women with an improved way of life.
The author considers those historians who describe early feminists in the US as "solitary" to be
A.insufficiently aware of the ideological consequences of the Seneca Falls conference.
B.overly concerned with the regional diversity of feminist ideas in the period before 1848.
C.insufficiently concerned with the social conditions out of which feminism developed.
D.insufficiently familiar with the international origins of 19th-century American feminist thought.
