    Most people think of sharks (鲨鱼) as huge, powerful, frightening predators (掠夺性的食肉动物), ready at any moment to use their sharp teeth to attack swimmers. There are a lot of (1) about sharks.

    First, there are about 350 species of shark, and (2) of them are large. They range in (3) from the dwarf shark, which can be only six inches long and can be held in the hand, (4) the whale shark, which can be more than 5 feet long.

    The second misunderstanding of shark concerns its terrible teeth whose (5) and type can vary greatly among the (6) species of shark. a shark can have from one to seven sets of teeth at the same time, and some types of shark can have several hundred teeth in each jaw. It is true that the cruel and predatory species do have extremely (7) teeth used to tear and cut their victim apart, many other types of shark, however, have teeth more suitable to holding than to cutting.

(8), not all sharks are predatory animals ready to strike out at humans. In fact, only 12 of the 350 species of shark have been known to attack humans, and a shark (9) attacks humans unless is made angry. the types of shark that have the worst (10) with humans are the tiger shark, the bull shark, and the great white shark. However, for most species of shark, even some of the largest types, there are no known instances of attacks on humans.

    This hotel is (11) in the main shopping street of North Chester, three hundred yards from the cathedral.

    The original building was (12) in 1710, but this structure has been largely transformed and extended, the present hotel having been completed in 1910. It is four storey (13) with a lift serving all floors. The public rooms comprise (组成) a dining-room seating fifty (14), a lounge and a bar. There are sixteen (15) and thirty double bedrooms, three of the latter having private bathrooms. (16) floor has one bathrooms and two separate WCs. All bedrooms are (17) with washbasins with hot and cold (18), and a slot meter controlled radio and gas fire. The courtyard around which the hotel is built provides (19) space for ten cars and there is (20) for twenty more off a side street two hundred yards away. This is quite inadequate (不足的).
