Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks (攻击) suggests that sharks don’t like the way humans taste! In fact, most people who are attacked by the shark are still alive after receiving only one bite (咬). Why is this?
There are many opinions to explain why sharks sometimes attack people. One opinion is that sharks are just curious (好奇的). We know that sharks are the strongest animals in their environment, so they are not afraid of anything. Naturally, that means they are curious when they meet something unusual. Because they don’t have hands or feet., the only way they can find out an object is to bite it! It is thought that sharks sometimes bite humans for this reason, and then swim away.
Scientists also say that sharks would not waste energy trying to eat a human, as we have a lot of bones (骨头). It is hard for a shark to eat us because sharks don’t have hands, and they can’t pull the meat off our bones. Maybe that’s why they only bite us once. Unluckily, one bite from a large shark is serious enough to hurt people greatly!
Another opinion is that sharks attack humans by mistake. Some sharks may sometimes mistake humans for a seal. An example of this is when a shark attack attacks a surfer. A surfer lying on a surfboard looks like a seal when seen from below. Sharks like seals because they have thick fat.
Whatever the reason for shark attacks on humans, sharks should be afraid of us. Sadly, we kill almost 40 million of them each year.

A.Sharks pull meat off bones when they eat.
B.Sharks might mistake humans for seals.
C.Sharks like to attack surfers because of their thick fat.
D.One bite from a shark is nothing serious.
小题4:What would the author write the passage mainly for?

It is true that people with better education are usually able to get better paying jobs. In other words, they have more chances to choose a good job while people with little or no education don’t. It seems that the purpose of education is to make people get jobs. But this isn’t accepted by all people.
Some people may think that a person should spend the best years of his life to get education only for a way of living. This was probably one of the earliest reasons of education. In fact, if education is just a way of making a living, people don’t need to spend so much time in school. People can get education for a living in a short time. Subjects like history and geography need not be taught to everyone. Even language and mathematics need not be taught in detail(详细地), either. Here it is clear that education is much more than teaching a man to get a way of living.
Education is well-rounded and it is mainly for improving a man. It is not only to teach him to speak, read and write, but also to develop his creative thinking and other abilities. After that, it is to make him a wise man and thankfully enjoy the achievements of human. Education is to make a man lead a better life. Educated people are expected to be able to listen to good music, read good books, watch plays and most of all take an interest in the world.
I would agree that making a good living is an important reason for education, but certainly not the most important or the main reason.
小题1:People with little education usually ____.
A.spend a long time in schoolB.have a good chance to get a job
C.spend the best years to choose jobsD.have fewer chances to get a good job
小题2:The earliest education was probably to ______.
A.make a man lead a better lifeB.teach a man to write and think
C.make people get a way of livingD.teach people to read good books
小题3:The underlined word “well-rounded” in the passage means “_______” in Chinese.
A.圆满的B.崭新的C.公平的D.全面的
小题4:It is expected that educated people will be able to _____.
A.accept education as a way of living
B.take an interest in the whole world
C.develop their abilities to make plays
D.learn subjects like language and math
小题5:The passage mainly tells us that _______.
A.education should make a man improve
B.people can get education in a short time
C.people should be able to get better paying jobs
D.all subjects are so important for a way of living

In classroom, your teachers will talk about topics that you are studying. The information they provide will be important for you to know when you take tests. So you must be able to take good written notes from what your teachers say.

Examples of signal words are “The most important point…” and “Remember that…”. Be sure to include in your notes information that your teacher repeats or writes on the blackboard. Write quickly so that you can include all the important information in your notes. Do this by writing abbreviations such as med for medicine, using symbols such as % for percent, and writing short sentences.
After Class
Rewrite your notes to make them more complete and accurate(准确的) by changing abbreviations into whole words, symbols into words, and shortened sentences into longer sentences. Use them to answer your questions. If necessary, ask your teacher for help.
