13．On our journey to Australia last summer，our luggage was _____ at the customs．We were not allowed to carry food such as meat and vegetables．（　　）

10．Solid passes sound very well．Try holding a wooden stick against part of a machine，and place your ears against the stick．The movement of the ball-bearings（滚珠轴承） can be clearly heard．This is a good way of finding the exact source of trouble in a motorcar engine which sounds as if it is wrong and yet gives no information of where the trouble is．
It is probably a good thing that sound cannot travel through a vacuum（真空），for we are thus limited to earth-made sounds．The violent disturbances which are seen sometimes in the sun，for example，may affect our magnetism（磁力） and our radio．They do not affect our ears，which is a very good thing for our peace of mind．
If we have used our eyes and ears，we may have realized that sound takes time to travel through the air．The sound of thunder nearly always follows the lightning flash although they happen at exactly the same time．And the appearance of white cloud above a distant ship or train tells us，before anything is heard，that its whistle has sounded．Just how fast does sound travel through the air？
The speed of sound in the air at ordinary temperature is about 100feet per second，which is about one mile in five seconds or about 700miles per hour．The speed of sound increases slightly with a rise in temperature and falls with a decrease in temperature； it is not affected by the pressure of the air．

24．We never hear anything that happens on the sunA．
A．because of the vacuum between the earth and the sun
B．because we are only used to earth-made sound
C．because of the distance between the earth and the sun
D．because we are likely to enjoy our peace of mind
25．According to the passage，how fast does sound travel through the air at ordinary temperature？C
A．About 700meters per minute．
B．About 1，100miles per hour．
C．About 60，000feet per minute．
D．About one kilometer in five seconds．
26．How do temperature and pressure affect the speed of sound？D
A．The speed of sound increase with a rise in pressure．
B．The speed of sound decrease with a rise in temperature．
C．The speed of sound increase in lower temperature and greater pressure．
D．The speed of sound decreases with a fall in temperature．
27．The underlined sentence in the second paragraph means"D"．
A．thus we can hear anything but the sound made by the earth
B．we can thus hear the sound from both the earth and space
C．thus we can hardly hear any sound because of the limit of the earth

For years she kept consulting specialists about her eye problems，only to be told that her son would also be blind by the time he was a teenager．She swore to find something，anything，to prevent him from facing her fate．When conventional medicine offered no hope，Grace began a personal quest．She entered a local college．The office for disabled students had her reading assignments put on cassette tapes so that she could listen and learn．She began studying anatomy，physiology and other health sciences．Everyone knowing her was astonished at her persistence to educate herself，restore her vision and keep focused on raising a son who would have perfect eyesight．
Eventually Grace's own way worked and she earned the Ph．D．in Holistic Health for her successful work in improving serious eye disorder．Her eyesight slowly improved so much that she was able to qualify for a driving license．Even better，her son had perfect vision and was accepted into the Air Force．
