Weather information consists of ten parts，of which ships usually make use of three，that is，warning，synoptic situation andforecast. With weather information，mariners are able to keep away from disastrousweather at sea and reduce the danger a great deal. As terrible weather is predicted，shipscan take precautions beforehand，by delaying the voyage or seeking shelter in a safeplace. If there is a high sea or a long swell，they can take some measures to safeguard thecargo and the ship.89 Weather information for ships is usually transmitted by coast radio stations ___.A. any time of the dayB. at fixed timeC. in different languagesD. in some parts of the worldB90 Coast radio stations generally provide weather information for ships ___. I. in code,II. In a certain language, III. in written formA. IB. I + IIC. IID.

All targets, fixed or moving, then move relative to the ship's position in the centre of the screen and the heading marker. As the ship moves through the water, fixed targets appear to track down the screen on a reciprocal heading at the speed the ship is moving and when the ship alters course targets appear to rotate in the opposite direction to that of the ship, so targets appear to move on the radar screen while the ship's heading remains fixed. The coating on a radar display is designed to allow a certain amount of afterglow (余辉) of targets, which in the ship's head up mode causes smearing(拖尾) and may make the identification of smaller targets difficult. In addition, when targets. particularly large landmasses, are in close proximity interference occurs, which can further inhibit the detection of small targets.89. When radar is set to ship's head up display, all fixed targets displayed on the screen will appear to当雷达被设置为船首向上显示，所有固定目标显示在屏幕上是向下倒退像标题头和船速一样A. track down the screen on a reciprocal heading at the speed the ship is movingB. rotate in the same direction as the ship rotatesC. make the identification of smaller targets difficultD. allow a certain amount of afterglow of targets90. In the ship's head up mode. if the ship rotates starboard-wise all fixed targets on the screen will appear to ______.在船首向上模式中，如果船舶右旋转，所有固定目标在屏幕上会看起来左旋转A. rotate starboard-wiseB. rotate port-wiseC. remain stationaryD. move on a reciprocal heading at the speed the ship is moving91. Afterglow of targets will ______.余辉的目标将被识别为更小目标A. have ship's heading marker fixed at 000°B. cause the fixed targets to remain fixedC. inhibit 禁止the detection of small targetD. make the identification of smaller targets92. It can be concluded that the instrument referred to in this passage is most likely a/an______它能被表达为工具指向短文是最可能是APRA。
