There are a lot of good cameras available at the moment—most of these are made in Japan but there are also good (S1) ________ models from Germany and the USA. We have (S2) ________ a range of different models to see which is the best (S3) ________ for money. After a number of different tests and interviews with people who are (S4) ________ with the different cameras being assessed, our researchers (S5) ________ the Olympic BY model as the best auto-focus camera available at the moment. It costs $200 although you may well want to spend more—(S6) ________ as much as another $200—on buying (S7) ________ lenses and other equipment. It is a good Japanese camera, easy to use. (S8) ________ whereas the American versions are considerably more expensive.
    The Olympic BY model weighs only 320 grams which is quite a bit less than other cameras of a similar type. Indeed one of the other models we looked at weighed almost twice as much. (S9) ________. All the people we interviewed expressed almost total satisfaction with it. (S10) ________.

    Lead deposits, which accumulated in soil and snow during the 1960’s and 70’s, were primarily the result of leaded gasoline emissions originating in the United States. In the twenty years that the Clean Air Act has mandated unleaded gas use in the United States, the lead accumulation worldwide has decreased significantly.
    A study published recently in the journal Nature shows that air-borne leaded gas emissions from the United States were the leading contributor to the high concentration of lead in the snow in Greenland. The new study is a result of the continued research led by Dr. Charles Boutron, an expert on the impact of heavy metals on the environment at the National Center for Scientific Research in France. A study by Dr. Boutron published in 1991 showed that lead levels in arctic (北极的) snow were declining.
    In his new study, Dr. Boutron found the ratios of the different forms of lead in the leaded gasoline used in the United States were different from the ratios of European, Asian and Canadian gasolines and thus enabled scientists to differentiate (区分) the lead sources. The dominant lead ratio found in Greenland snow matched that found in gasoline from the United States.
    In a study published in the journal Ambio, scientists found that lead levels in soil in the Northeastern United States had decreased markedly since the introduction of unleaded gasoline.
    Many scientists had believed that the lead would stay in soil and snow for a longer period.
    The authors of the Ambio study examined samples of the upper layers of soil taken from the same sites of 30 forest floors in New England, New York and Pennsylvania in 1980 and in 1990. The forest environment processed and redistributed the lead faster than the scientists had expected.
   Scientists say both studies demonstrate that certain parts of the ecosystem (生态系统) respond rapidly to reductions in atmospheric pollution, but that these findings should not be used as a license to pollute.

    Exercise is one of the few factors with a positive role in long-term maintenance of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to “light” beer and low-calorie bread than increase physical exertion. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.
    In rejecting exercise, some people may be discouraged too much by caloric-expenditure charts: for example, one would have to briskly walk three miles just to work off the 275 calories in one delicious Danish pastry (小甜饼). Even exercise professionals concede half a point here. “Exercise by itself is a very tough way to lose weight,” says York Onnen, program director of the President’s Council on Physical Fitness and Sports.
    Still, exercise’s supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
    If you have been sedentary (极少活动的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year’s time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.

Most people agree that the present role of women has already affected U.S. society. ________, it has affected the traditional role of men.

    Wise buying is a positive way in which you can make your money go further. The (1) ______ you go about purchasing an article or a service can actually (2) ______ you money or can add (3) ______ the cost.
    Take the (4) ______ example of a hairdryer. If you are buying a hairdryer, you might (5) ______ that you are making the (6) ______ buy if you choose one (7) ______ look you like and which is also the cheapest (8) ______ price. But when you get it home you may find that it (9) ______ twice as long as a more expensive (10) ______ to dry your hair. The cost of the electricity plus the cost of your time could well (11) ______ your hairdryer the most expensive one of all.
    So what principles should you (12) ______ when you go out shopping?
    If you (13) ______ your home, your car or any valuable (14) ______ in excellent condition, you’ll be saving money in the long (15) ______.
    Before you buy a new (16) ______, talk to someone who owns one. If you can, use it or borrow it to check it suits your particular (17) ______.
    Before you buy an expensive (18) ______, or a service, do check the price and (19) ______ is on offer. If possible, choose (20) ______ three items or three estimates.
