高三英语阅读理解训练题：letter

Are you thinking of writing someone a letter? Call instead. It isn't that expensive, especially when you call during the evening, night, or weekend hours. In fact, you can make a ten-minute call anywhere in the continental United States for just $2.60.

For even greater saving, always dial direct, that is, without an operator's help. Rates(资费) on direct calls are lower after five o'clock in the evening and lowest after eleven o'clock at night. Collect, person-to-person, and pay phone calls require the services of an operator, and they cost more than direct calls.

Need to call out of the country? Now calls to many overseas places may be dialed direct. Check your telephone direction for overseas area codes.

Next time you have good news, or you just want to stay in touch, remember, a phone call means so much more than a letter. This has been a message from Southern Bell Telephone Company.

高三英语阅读理解训练题：

obstruction

Under proper conditions, sound waves will be reflected from a hillside or other such obstruction(障碍). Sound travels at the rate of about one-fifth of a mile per second. If the hill is eleven hundred feet away, it takes two seconds for the sound to travel to the hill and back. Thus, by timing the interval between a sound and its reflection, you can estimate the distance to an obstruction.

During World War II the British used a practical application(应用) of this law to detect German planes on their way to bomb London long before the enemy was near the target. They used radio waves instead of sound waves, since radio waves can make a way through fog and clouds. The outnumbered Royal Air Force always seemed to the puzzled Germans to be surprised.

It was radio echoes(回声) more that anything else that won the Battle of Britain.

Since the radio waves were used to tell the direction in which to send the RAF planes and the distance to send them(their line of flight, in other words), the device was called radio direction and ranging, and from the initials the word radar was invented.
