The modern mobile phone is a more complex version of the two – way radio, which was a very limited means of communication. As soon as the users moved out of range of each other’s broadcast area, the signal was lost. In the 1940s, researchers began experimenting with the idea of using a number of radio masts (天线塔) standing around the countryside to pick up signals from two-way radios.
The first real mobile telephone call was made in 1973 by Dr Martin Cooper, the scientist who invented the modern mobile handset. Within a decade, mobile phones became available to the public. The streets of modern cities began to feature sharpsuited characters shouting into giant plastic bricks. In Britain the mobile phone quickly became synonymous (等于) with the “yuppie”, the new breed of young urban professionals who carried the expensive handsets as status symbols. Around this time many of us swore that we would never, ever own a mobile phone.
But in the mid-90s, something happened. Cheaper handsets and cheaper calling rates meant that, almost overnight, it seemed that everyone had a mobile phone. And the giant plastic bricks of the 80s had evolved into smooth little objects that fitted nicely into pockets and bags. Cities suddenly had a new, postmodern birdsong.
Alexander Graham Bell would be amazed if he could see how far the science of telephony has progressed in less than 150 years. If he were around today, he might say: “That’s gr8! But I’m v busy rite now. Will call U 2nite.”

Today we have the second report explaining how to prepare fish by drying or smoking them. We talked last week about the first steps of cleaning and salting freshly caught fish.
To dry fish, you will need either a drying table or a place to hang them. If a table is used, it should have a top made of wire screen or thin pieces of wood with space between each piece.
Lay the cleaned, wet salted fish on top of the table. Do not let them touch each other. Be sure that air can reach the fish from all sides.
For best results, put the drying table under a tree. Turn the fish over every other day. Small fish will dry in about three days if the air is dry. Large fish will take a week or ten days to dry.
After the fish have dried, place them in a basket. Cover them with clean paper or large leaves. Then put the basket in a cool, dry place off the ground.
Make sure as much of the saltwater as possible is removed before you smoke the fish.
The smoking can be done in a large, round metal container. Remove the top of the drum and cut a small opening on one side at the bottom.
Cover the top with a strong wire screen, where you put the fish. Build a small fire in the drum by reaching in through the opening at the bottom.
Wood from fruit trees makes good fuel for your fire. It will give the smoked fish good color and taste. One way to get a lot of smoke is to use green wood, not dried wood.
You should smoke the fish for five days or longer if you plan to keep them for a long time. After that, wrap them in clean paper, put the fish in baskets and keep them in a cool, dry place off the ground.
64. From the underlined sentence in Paragraph 4 we can learn that .
A. people prefer to dry fish under a tree

C. under a tree is the only place for you to dry fish
D. fish taste best if they are dried out of bright sunlight
65. The underlined word “it” Paragraph 9 refers to “ ”.
A. the wood B. the fuel C. the fire D. the smoke

A. To smoke fish, you have to salt the fish first.
B. Smoked fish can only be kept in a basket.
C. You’d better use dried wood to smoke fish.
D. Smoked fish taste better than dried fish.
67. In drying or smoking fish, the following tools are mentioned in the passage EXCEPT .
