Have you ever seen the film Titanic? “Titanic” was one of the largest and finest ships in 1912. It hit an iceberg(冰山)on its first sailing from England to America and sank very soon, leaving a love story to the people. Do you know what an iceberg is?
The earth is round, like a ball. The top of the earth is the north. The bottom of the earth is the south. At the top and the bottom of the earth, there is a lot of ice. It is very cold there. Sometimes there is no sunshine for many months. There is ice everywhere all the time. Large pieces of ice fall into the sea. They don’t go to the bottom of the sea. They float(漂浮)near the top of the water. We call these large pieces of ice “iceberg”. Some icebergs are bigger than a tall building. Icebergs are dangerous for ships. Sometimes a ship hits an iceberg.
Then the ship sinks.
You can make a small iceberg. Put a piece of ice in a glass of water. Look ar it. The ice does not sink.

答案：
(答案→)ship
解析：
1.ship根据“Titanic” was one of the largest and finest ships in 1912（泰坦尼克号是是19最大最好的轮船之一）可知泰坦尼克号是一艘轮船，故为ship。
2.because根据It hit an iceberg(冰山)on its first sailing from England to America and sank very soon可知它首次出航撞上冰山并很快下沉，两者是因为关系，故为because。
3.weather从下面的cold（寒冷的）可知讲的是天气，故为weather。
4.sun/sunshine根据Sometimes there is no sunshine for many months可有有许多个月看不到阳光（也即看不到太阳），故答案为：sun/sunshine。
5.ice根据We call these large pieces of ice “iceberg”可知大的冰块我们称为冰山，故冰山是由冰组成的，答案为ice。
