[填空题]
In the summer heat, it’s easy to develop the embarrassing
problem of body odor if you’re not careful. Bacteria live all over our skin, and
their waste is what causes body odor.
Follow these simple tips
to keep the bacteria away:
1. Use antibacterial body
soap.
Antibacterial soaps kill the odor-causing bacteria on the
body. If you haven’t been using one, chances of the bacteria levels on your body
are quite high, so get their numbers under control by bathing with your new soap
twice a day for two weeks. After levels are back to normal, once a day is enough
to keep them in check.
2. Change clothes and bath towels
frequently.
Any worn clothing or used bath towel will produce
bacteria. Change your clothes daily, especially socks and underwear, unless you

Passage Two
Among the question of design, construction, and operation remaining to be solved before commercial airliners travel faster than sound is the difficult problem of sonic boom (声震) , the explosive sound generated when an object moves through the air at supersonic speed(超音速).
A sound is a pressure disturbance: a sonic boom, like other explosive sounds, is the result of an abrupt change in pressure. An airplane in subsonic flight produces weak changed in pressure, but because these disturbances travel at the speed of sound, they move faster than the airplane and stay in front of it. In effect, these disturbances warn the air to get out of the way, and the an does just jet, however, gets ahead of its own pressure disturbances. Consequently a wave of suddenly com pressed air--a shock wave--builds up and is thrown off like the wave ;hat spreads from the bow of a speedboat.
Can sonic booms be eliminated The answer is a categorical negative--they
A. design
B. Construction
C. operation
D. all of the above

I Know Just How You Feel
Do you feel sad Happy Angry You may think that the way you show
these emotions is unique. Well, think again. Even the expression of the most
personal feelings can be classified, according to Mind Reading, a DVD displaying
every possible human emotion. It demonstrates 412 distinct ways in which we
feel: the first visual dictionary of the human heart.
Attempts
to classify expressions began in the mid-1800s, when Darwin divided the emotions
into six types -- anger, fear, sadness, disgust, surprise and enjoyment.
{{U}} (46) {{/U}} Every other feeling was thought to derive from Darwin’s
small group. More complex expressions of emotion were probably learned and
therefore more specific to each culture. But now it is believed that many more
facial expressions are shared worldwide. {{U}} (47) {{/U}} The Mind
