    9．I am a professor of sports and exercise so I often deal with nervousness in my research with sports people．Actually，most people experience nervousness at some time or another．
    If you are feeling anxious，my advice is to first find the cause or causes．Make a list of those things that are making you nervous and work out which ones you can do something about．Focus all of your efforts on managing the causes that you can control．
    Most people cannot tell the difference between controllable（可控制的） and uncontrollable causes，so things they can's control become a big reason for nervousness．Dealing with this is very important if people want to keep a healthy mind．
    Simply try to accept the uncontrollable causes of nervousness．You might be worried about the weather on a big day，an accident or an attack on the train，or perhaps just things that other people are doing at work．The results may be very important but there is still no use worrying because you can't control any of these things．Accept that you can't control everything．Once you understand this，it becomes easier not to worry．
    If a situation，such as swimming，is causing you to be anxious，try to face it as often as possible so that you can get used to it．
    It can often help to think about yourself doing the thing that makes you nervous-then close your eyes and imagine it going well．Imagine how the flight or job interview is going to happen so that you can get used to it．This will help you understand that the thing you fear most is probably not going to happen．

    6．All across California，honeybees are flying away from their hives（蜂箱） and dying．Empty hives are causing a lot of worry about some important food crops．
    Bees gives us a lot delicious honey．They are pollinators（授粉昆虫）----they enable plants to produce the fruits and nuts we enjoy by carrying pollen from one plant or flower to the next．The wind pollinates oats，corn，and wheat，but many other plants （like apple and cherry trees and melon vines） depend on insects，bat，and birds．In the U．S．，millions and millions of bees kept by human beekeepers fly around doing a lot of this important work for food crops．"Bees are worth protecting because their work adds so much to our diet．"says Dr．Jeff Pettis of the Bee Research Laboratory．
    California's almond crop alone depends on about half the bees in the country．But now the almond crop and many others could be in trouble with so many bees dying．
    Researchers at government and university labs all over the country are trying to figure out why so many bees are dying．However，bees are hard to study．Most die away from the hive，so researchers don't have dead bodies to examine．And when researchers return to a hive after two weeks，about half the bees they studied on their first visit will be dead，replaced by new ones in the natural life cycle of bees．"It isn't like studying a large animal like a cow that doesn't move around much and is easy to find out in the cow field，"says Pettis．
    Researchers have some ideas about what could be affecting bees'health．They could be sick because of poisons widely used to kill insects，or they might not be getting enough good food to stay strong．Also，tiny insects called mites feed on bees．"A virus or bacteria could also be doing the killing，"explains Pettis．
    32．What is Paragraph 2 mainly about？B
    A．The wind helps pollinate．
    B．Bees are important for food crops．
    C．Bees give us a lot of delicious honey．
    D．Cherry trees are pollinated by bees．
    33．Bees are hard to study becauseA．
    A．they move around too much．
    B．new bees soon replace all the bees studied by researchers．
    C．they are too tiny．
    D．they never return to hives．
    34．What could cause so many bees to die？D
    A．Poisons to kill birds．
    B．Eating too much．
    C．Large insects．
    D．Some virus．
    35．What can we learn from the article？B
    A．A large number of bees have died in the hive．
    B．Without bees，some food would disappear from our diet．
    C．Only researchers in California want to know what kills bees．
    D．Large animals are mo re difficult to study than tiny insects．
