4 . It’s very important to use the summer break effectively. The break should be seen as an extended part of your education. You can learn about the world, about life, and most importantly, about yourself. You could also obtain some valuable experience. An effective break will bring you more satisfaction and contribute to your future.     1     And you can make this summer break the one that could change your life. These tips may help you.

Be organised. Before your break starts, do some research and make a plan. Take travel for example. You have to find out about the destination. How to get there? Where to stay? How much to spend? And so on and so forth.     2    

Be money-minded. Will you spend money or save it? Will you need to borrow money? Budgeting is an essential life skill to master.     3     For example, perhaps you could find paid or voluntary work that is away from home, which will also give you lots of travel experience.

    4     If you’re going away from home, make sure you go to a reputable place. Always let your parents know where you are. It’s best to travel with friends, too.

Be happy. Although planning an effective summer break can be stressful, it is essential to ensure that you have a safe and pleasant time!     5     It will enable you to gain experience and have fun at the same time.

5 . Though shark attacks can be a rare occurrence, there have been 46 publicly reported shark attacks so far this year. Then why do sharks attack humans? Here's everything we know.

Shark attacks are often put into different categories: provoked (被挑衅) and unprovoked. “Unprovoked bites” are defined as incidents in which a bite on a human occurs in the shark's natural habitat with no human provocation of the shark. “Provoked bites” occur when a human starts interacting with a shark in some way. For instance, when divers are bitten after attacking or trying to touch sharks.

Roger Tabor, a biologist and naturalist, says, “There is no evidence that sharks specifically hunt people.” Nowadays, a theory called the Mistaken Identity Hypothesis (假说) explains shark bites on surfers, swimmers and divers as “mistakes,” which typically means that sharks might confuse humans with their typical prey (猎物). Mr. Tabor says surfing has previously been linked to shark attacks because the sudden movement, similar to an animal suddenly moving back, or bright parts of wetsuits reflecting looking like a fish, can cause a response in the visually oriented (导向的) great white".

In a paper published by Eric Clua, a marine biologist and Carl Meyer, a biologist at the University of Hawaii, in the Brill Journal, they look at the MIH theory. The paper says that although MlH may now be “widely” accepted by the general public and the scientific community, there are still some unknown gaps. “This hypothesis ignores the important role of other senses (e.g. hearing) in discriminating potential prey,” the paper says. The authors also note that shark bites which occur in clear water cannot always be explained by MIH. It adds," To put it simply, sharks don't make ‘mistakes’ but instead continually explore their environments and routinely investigate novel objects as potential prey by biting them.”

Climate change may be another reason for seeing an increase in shark attacks. Mr. Tabor says," Global warming and habitat damage can move marine species including seals and sharks. That can bring larger sharks more into contact with beaches, with people.”

6 . Imagine you are on your way out of class today. You trip on a loose piece of carpet and break your ankle. As a result of the injury, you lose your place in the local sports team. Bad luck? Or an opportunity to get rich quickly?

Roslyn Darch of Houston felt annoyed when she tripped over a little kid running around a furniture store, and broke her ankle. But a few months later, she was $780,000 richer, after she successfully sued (起诉) the shop. The owner was clearly surprised at Roslyn’s compensation, particularly since the child she tripped over was her own son.

Some argue that this is just greed—that the amount of money is far too much for the injury suffered—and besides, it’s not the shop’s fault that a mother can’t control her child anyway. Others would say that it’s good to see the law taking the side of the individual against the big corporations, for a change. Take the example of the hundreds of smokers who have received millions of dollars from the tobacco companies, after saying they were responsible for the terminal illnesses they had developed because of smoking. Whatever you think, the compensation culture which has emerged in recent years is spreading, and it will affect all of us.

And it’s not only claims for physical injuries that are keeping the lawyers busy. A group of overweight New York teenagers sued giant fast-food company, claiming that they had not had enough warning that a diet of burgers, fries and milkshakes would make them fat.

Who knows where it will end? Some say there should be penalties (处罚)for excessive claims, or that there should be a limit on payouts. But one thing’s for sure—in the end, the only certain winner is the lawyer!
