    Since the gene, called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging, immunity(免疫)and resistance in humans, the scientists said.?

    “We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits, such as immunity,” said Robin May of the University of Birmingham, who led the study.?

    Populations across the world are aging at a surprising pace, bringing potentially big challenges for health and social care systems. A study by Danish scientists last year found that half of babies born in the rich world today will live to celebrate their 100th birthdays. Scientists are eager to find out how people age to try to develop drugs to help them stay healthier as their lives extend.?

    “What we have found is that things like resistance and aging tend to go hand in hand,” May said in an interview.?

    May’s team compared longevity, stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAF-16 in each of the four species, and found that they were all quite distinct.?

    May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes, which scientists believe play a role in the aging process.?

    “The fact that subtle（微妙的）differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and may explain how differences in lifespan and related traits have arisen during evolution,” May said.?

    67. In which section may the text appear in a newspaper? ?

       A. Education.              B. Science.          C. Entertainment.         D. Culture.

    68. What can we know from the third paragraph??

    A. New ways have been found to affect aging. ?    B. Babies in the rich world will all live longer. ?

    C. Present social care systems are poorly managed.? D. Aging populations are causing more challenges.

    69. From the text we know that DAF-16_____.?

    A. is a gene that is only found in worms?           B. can make people live longer?

    C. has an effect on aging and immunity?            D. has been quite familiar to scientists

    70. What can be the best title of the passage??

    A. Scientists Find Gene Linked to Aging?           B. Population Aging Faster than Expected?

    C. How to Make People Live Longer?              D. Gene Determines How Long We Live?

    The massive 8.8 quake, the seventh strongest in recorded history, hit Chile and should have shortened the length of an Earth day by 1.26 milliseconds, More impressive is how much the quake shifted the Earth’s axis（地轴）.

    The computer mode! Used to determine the effects of the Chile earthquake effect also found that it should have moved the Earth’s figure axis by about 8 cm. The Earth’s figure figure axis is not the same as its north-south axis, which Earth turns around once every day at a speed of about 1,604 kph. The figure axis is the axis around which the Earth’s mass is balanced. It is offset（偏离） from the Earth’s north-south axis by about 10 meters.

    Strong earthquakes can change Earth’s days and its axis. The 9.1 Sumatran earthquake in 2004, which set off a deadly tsunami（海啸），should have shortened Earth’s days by 0.0068 milliseconds and shifted its axis by about 7cm.

    One Earth day is about 24 hours long. Over the course of a year, the length of a day normally changes gradually by one millisecond, It increases in the winter when Earth more slowly, and decreases in the summer.

    The Chile earthquake was much smaller than the Sumatran quake, but its effects on the Earth are larger because of its location. The fault（断层） responsible for the 2010 Chile quake also cuts through Earth at a larger angle that the Sumatran quake’s fault. This makes the Chile fault ore effective in moving the Earth’s mass vertically and hence more effective in shifting the Earth’s figure axis.

    The findings are based on early date available on the Chile earthquake. The Chile earthquake has killed more than 700 people and cause widespread damage in the South American country.

    64．What’s the biggest problem caused by the Chile quake?

    A．It is the seventh strongest in recorded history. B．It should have shortened the length of an Earth day.

    C．It shifted the Earth’s axis.                D．It made the day longer on Earth.

    65．Comparing the Sumatram earthquake with the Chile earthquake, we know that        .

    A．the Sumatram earthquake had more effect on Earth

    B．the location of the Chile earthquake is responsible for its larger effects on Earth.

    C．the Sumatram earthquake was less destructive

    D．the Chile earthquake fault changed the Earth’s mass

    66．What does the word “it” in the 4th paragraph refer to?

    A．The length of a day.        B．The axis.     C．One millisecond.      D．The change of the day.
