题文
The summer beach season is prime time for shark attacks. It seems like sharks are attacking all the time. But that is something of an illusion. The number of attacks is very small.How does a shark hunt? Muscles and fins give the shark its speed and maneuverability in the water. A shark’s front fins act like the wings of a plane and let it “fly” through the water. The tail acts like a high-power propeller
But the big thing that gives the shark its edge in the ocean is its sensory package. The package includes the shark’s eyes, ears, skin, nose and mouth, as weir as electric sensing.
A shark’s nose is probably its most important sense. If you were to put a single drop of blood in a swimming pool, a great white shark could smell that. And they can tell the direction that the smell is coming from.
Sharks handle their electric sensing using cell located in the head. Whenever something moves using its muscles, a shark can detect the electrical impulses flowing to those muscles. A shark can electrically “see” anything that has muscles even if it is hiding or the water is not clear.
Sharks even have vibration sensors in their skin. Even something moves near the shark, tubes pick up the pressure changes and hairs inside the tubes send signals to the brain. This extra sense allows a shark to turn quickly and attack again.
When you put all these different senses together , it makes the shark a nearly ideal hunter. A shark can detect prey from miles away and then use eyes, electrosensing and movement sensing to home in.
Strangely, sharks do not seem to use these senses to home in on people. The very low number of sharks tells us that sharks do not hunt people in a regular basis. On the other hand, people love to hunt sharks, Millions of sharks die every year. Without protection, extinction is a definite possibility.

1、重点理解全文的首句。如果是记叙文，找出when，where，who，what等基本要素。如果是散文随笔，充分理解文章的中心句—全文的主题。
2、阅读全文的结尾段或结尾句，有助于理解文章所阐述或蕴含的哲理、感悟或忠告等。
3、调动自己的背景知识和情感。这类文章不会讲大道理也不会涉及到一些很专业的知识技术领域，而是谈一些小事和简单的道理，所以如果读者能和作者产生感情上的共鸣，读者会更好地把握作者的意图态度，从而提高做题的准确度。因此，考生在平时要做一个有心人，即用心去感悟生活中发生的小事，思考人生的一些基本道理，多阅读一些短小精悍的美文，多写写自己的心情故事和对生活学习的感悟。只有平时多用心，做题时才能调动自己的背景知识和情感。
