There are nearly 400 different types of sharks, but only about 30 types have even been reported as attacking human beings.
The chances of being attacked by a shark are very small compared to other dangers. Many more people drown（溺死）in the ocean every year than are bitten by sharks. The low number of attacks that happen every year proves that sharks do not feed on humans if they have the choice. There are three types of shark attacks. The main one is known as a ‘hit and run’. The shark attacks because it thinks you are a fish, but when it tastes a human it decides not to eat you. The second type is called a ‘bump and bite’. The shark bumps you to find out if you are fit to be eaten and then bites you if it thinks you are. The third type is called a ‘sneak’. When attacking in this way, the shark waits for you to swim by and attacks you suddenly. The latter（后者的）two types of attack are more likely to be deadly for humans.
However, your chances of being attacked by a shark can be reduced if you follow the advice below.
Do not swim in the dark. Sharks can still see you but you cannot see them.
Do not swim if you are cut or if you have a fresh wound. Sharks can smell blood over a long distance.
Do not wear bright clothing or jewellery because sharks are attracted to colours and shiny objects.
Try and stay in groups, as sharks usually avoid large numbers of people.
Don’t be frightened（受惊吓）by sharks as there is 30 times greater chance of being hit by lightning than being attacked by a shark.

What will you do to make sure you reach your goals? There are 1 main steps .
First, sit down and 　2 your dreams out. By writing them you will get a better idea of where you really want to go. Imagine yourself at the end of the year or maybe 3　 five years. What do you see? 4 do people see you? What are you doing? Are you 　5　?
Well, a dream is just that. It’s a vision (远见) of how you 　6　 yourself in the future. As long as you know the direction in which you want to go, you can begin 　7　 some goals.
8 come the goals. Goals are ‘wants’. So are dreams, but goals are more specific (具体的). If you want to be rich, tell how much 9 you need to be rich. If you want 　10 grades, tell what you mean by ‘good’. In fact, the more specific the goal is, the 　11　 it will be to get it. Give numbers and times. Don’t use words like ‘lots’ or ‘more’. 　12, I want a ‘B’ in each of my subjects.
Third are the objectives (目标). They tell 　13　 what you will do and when you will do it. When you think about what you will do, don’t use words like ‘　14　’ or ‘maybe’. Be sure your objectives can be measured (估量). Every day or every week you can ask, ‘Did I 　15　 this?’ and you can answer with either a yes or a no. Don’t leave room for ‘maybes’.
