       A leading researcher into old age has warned that the dream of living forever, or at least much longer than at present, could turn into a curse（禍根）rather than a blessing. It may become possible to lengthen the    1    human life by controlling genes---but what we gain may not be worth the price we would have to pay.

       Professor John Grimley Evens believes that    2   , maximum life expectation is 115, but that with gene    3    it might be possible to extend this. The professor says, however, that a

4    lifestyle can extend the average lifespan of everyone at the moment.

       “We know a lot already about how people’s lifestyles    5    their lifespan. There is increasing    6    to suggest that sensible lifestyles are effective in later life as well as in early and middle life.”

       “It is never too late to gain some    7    from giving up smoking, from drinking less alcohol, from taking up sensible patterns of diet and exercise and from controlling body weight. We already know how to     8    human life.”

       The professor believes that the process of lengthening life by means of gene therapy might bring dangers with it. If gene therapy affected only one part of the human body but not all of it, people might be    9    capable of living longer, but would start to be worse mentally at a much earlier age.

With oil prices approaching the symbolic mark of $ 100 a barrel, the world is heading towards its third energy shock in a generation. But today's rise is   1    different from the oil crises in the 1970s and 1980s. It will have a greater global impact.

       The   2    oil shocks were caused by sudden interruptions in exports from the Middle East. But this time prices have been rising steadily as   3   gasoline in both developed countries and developing economies grows. This is the world’s first demand-led energy shock.

       Oil prices   4  $ 98.6 on the New York Mercantile Exchange before falling back to $ 96.4 at the close of trading last Wednesday. Forecasts of future oil prices   5    widely. Virtually no one foresees a return to the $20 oil of a decade ago. It means consumers should face an era of high fuel   6   .

       For most of the 20^th century,   7   was cheap and abundant. Throughout the 1990s,

   8  ,oil prices averaged $20 a barrel. Even at today’s highs, luckily, for the Americans, oil is

   9  than imported bottle water.

       The concern today is over how the   10    sector（行業(yè)）will meet the growth in demand over the longer term.

       China faces the   11   . Rapid industrialization has come at a price: Oil demand has increased more than three times since 1980. It turned a country that was once self-sufficient into an oil   12   .

       Today, however, China consumes only a third as much oil as the US, which burns a quarter of the   13   oil each day. Europe has managed to reduce oil consumption through high gasoline taxes, small cars and   14   public transportation. But Americans have not.

       Experts say no one should count on oil prices rising forever. Economic   15    in the world’s major economies will probably send prices down.

They say there are three ways to experience the Grand Canyon; on foot, on mules（騾子）or by air. We chose the first. Up early; my husband and I and our three children couldn’t wait to get started. We decided to walk along a lovely path named Bright Angel Trail.

       As we set out, I was shocked at how narrow the path was. And I couldn’t help noticing that the other tourists weren’t like us. They had heavy backpacks, water bottles, and hats. But as usual we were dressed, As the sun rose higher, Arizona’s famous heat seemed to roast us. There was no shade and our legs were aching. We decided to go back, with the girl on my back and the boys far behind. By the time we finally got back, our legs were like jelly.

20090320

       The next day, after we’d had a long rest and a good breakfast, we were ready for another view of the Canyon – by air. After our last walk, this would be the easiest thing in the world.

       We called to each other excitedly as the plane took off and circled around the Canyon. But the smiles on our faces disappeared as the pilot tossed（翻轉(zhuǎn)）the plane around, pretending he was going to hit the ground. I shouted, “STOP, TAKE US BACK!” When we finally arrived back on land, once again our legs were like jelly. We hardly spoke as we drove back.

       As I said, there are three ways to view the Grand Canyon. We never tried the mules, but personally I’d suggest a fourth: buy yourself a good magazine like National Geographic. That way, you can see the Canyon, without fear or tiredness.

1．Which of the following is true according to the second paragraph?

       A．They made a careful preparation before the trip.

       B．They children were more joyful than their parents.

       C．Bright Angel Trail was not as lovely as they expected.

       D．The summer heat prevented them from enjoying the view.

2．The underlined expression “Our legs were like jelly” probably means         .

       A．we were weak                                     B．we were unhappy

       C．we were dissatisfied                             D．we were disappointed

3．Which of the following best describes their Canyon trip by air?

       A．It proved to be frightening.                   B．It was more comfortable.

       C．It turned out to be exciting.                   D．It made each of them tired.

4．We can infer from the passage that              .

       A．experiencing the Canyon on mules would be the best way.

       B．one needs to dress less when visiting the Grand Canyon.

       C．the writer was not serious when she made the suggestion.

       D．the whole family narrowly escaped from the air accident.
