Major coast radio stations all over the world transmit，at regular intervals and in code，weather information for ships within range. Weather information consists of ten parts，of which ships usually make use of three，that is，warning，synoptic situation and forecast. With weather information，mariners are able to keep away from disastrous weather at sea and reduce the danger a great deal. As terrible weather is predicted，ships can take precautions beforehand，by delaying the voyage or seeking shelter in a safe place. If there is a high sea or a long swell，they can take some measures to safeguard the cargo and the ship. 89 Weather information for ships is usually transmitted by coast radio stations ___.
A. any time of the day B. at fixed time C. in different languages D. in some parts of the world
90 Coast radio stations generally provide weather information for ships _. I. in code, II. In a certain language, III. in written form A. I B. I + II C. II D. I + II + III KEY:A 91 Weather information usually tells people something about weather _____.

Passage 3-5短距离通信
Communications over relatively short distances can be made by visual or sound signals. Visual signals can be sent by using flags or an Aldis lamp. An Aldis lamp is an electric lamp used for flashing messages in Morse code. The traditional method of signaling from one ship to another is by using flags. There are different colored flags for each letter of the alphabet. There are also pennant-shaped flags for numbers，and a long pennant，known as an answering or code pennant. Three other flags，which are burgee-shaped，are known as substitutes. These show that the flat or pennant is being repeated. Besides standing for a letter of the alphabet，each flag，when hoisted along，has another meaning. For example，the \flag also means: \require medical assistance\Flags can also be hoisted in combinations of two，three or four. Siren，whistle，bell or other sound signals can be used in fog and similar circumstances when visual signals can not be seen.
