Scientists believe that one of our most important means of knowing what is going on around us is the sense of sound. We are warned of danger by sounds. Sounds serve to please us in music. Sound has a waste product, too, in the form of noise. Noise has been called unwanted sound. Noise is growing and it may get much worse before it gets any better.

In order to know how noise affects people and animals, scientists have been studying for several years. They are surprised by what they have learned. Peace and quiet are becoming harder to find. Noise pollution is a threat that should be looked at carefully.

Sounds is measured in units called decibels (分貝). At a level of 140 decibels people feel pain in their ears.

Trucks , buses , motorcycles, airplanes, boats, factories---all these things make noise. They trouble not only our ears, but minds and bodies as well.

There is a saying that it is so noisy that you can’t hear yourself think. Doctors who study noise believe that we must sometimes hear ourselves think. If we don’t, we may have headaches, other aches and pains, or even worse mental problems.

Noise adds more tension (緊張) to a society that has already faced enough stress.

1.The sense of sound _________.

A. makes us feel excited

2.When sound is turned into noise, ______________.

B. it makes us forget all the past

C. people don’t know what to do with everyday life

A. Because the world is making more and more noise.

B. Because wars and battles happen here and there in the world.

C. Because all the sounds are becoming over 140 decibels.

D. Because some machines can make noise.

4.Doctors say we can hear ourselves think __________.

Buckingham Palace is where the Queen lives. It is the Queen’s official and main royal London home.

Buckingham Palace was originally a splendid house built by the Duke(公爵) of Buckingham for his wife. George IV began changing it into a palace in 1826. It has been the official London home of Britain’s royal family since 1837. Buckingham Palace is also an office and used for the administrative work of the royal family.

When the Queen is at home you can see her royal flag (the Royal Standard) flying from the flag pole on top of Buckingham Palace. The flag is divided into four equal parts. The first and fourth parts represent England and contain three gold lions waking on a red field; the second part represents Scotland and contains a red lion standing on a gold field; the third part represents Ireland and contains the gold coat of arms of Ireland on a blue field.

In flag protocol (禮儀), the Royal Standard which must only be flown from buildings where the Queen is present is supreme (至高無上的). It flies above the British Union Flag (the Union Jack), and other British flags. It never flies at half mast.
