Should we be afraid of sharks? Maybe not. New research into the reasons for shark attacks 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 didn’t die 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 . 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.

When you watch TV programs about wild animals, it is surprising to see how an antelope (羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight off enemies.
Over millions of years, plants have developed their own defense system (防卫系统). Chemicals are fantastically used by plants to survive (幸存). By making their leaves, flowers, roots and fruits poisonous (有毒的) to enemies, plants can fight back.
One such plant is the Golden Wattle tree. The British scientist David Cameron has found when an animal eats the tree’s leaves, the amount (数量) of poison increases in the other leaves. “It’s like the injured leaves telephoning the others to fight together against the enemy,” he said.
The tree also sends defense messages to neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die.
Every kind of plant or tree is good at producing a special set of chemicals. Herbivores, like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor.
In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest. From the first 2 paragraphs, we can learn that _________.
A.plants can do nothing against their enemies |
B.chemicals are quite useful for plants to survive |
C.an antelope can always run away from a strong lion |
D.leaves, roots, flowers and fruits of plants are poisonous |
If animals eat one Golden Wattle tree’s leaves, the tree can________.
A.kill the animals with a special smell |
B.tell other trees to come to protect it |
C.warn other trees against the animals on the phone |
D.send defense messages to the neighboring plants |
The underlined word “herbivores” in the 5th paragraph probably means animals which _____.
A.produce poison | B.live on small animals |
C.like to eat rabbits | D.feed on plants or grass |
The last paragraph of the passage suggests that this kind of defense system is ________.
A.bad for animals | B.good for forests |
C.helpful to some animals | D.harmful to forests |
The passage is mainly about __________.
A.the examples of protecting forests |
B.the balance between animals and plants |
C.the ways of plants fighting against enemies |
D.the relationship between lions and antelopes |

Different weather makes people feel different.It influences health, intelligence(智力) and feelings.
In August, it is very hot and wet in the southern part of the United States.People there have heart trouble and other kinds of health problems during this month.In the Northeast and the Middle West, it is very hot at some times and very cold at other times.People in these states(州) have more heart trouble after the weather changes in February or March.
The weather can also influence intelligence.For example, in a 1983 report by scientists, IQ(智商) of a group of students was very high when a very strong wind came, but after the strong wind, their IQ was 10% lower.The wind can help people have more intelligence.Very hot weather, on the other hand, can make it lower.Students in many schools of the United States often get worse on exams in the hot months of the year (July and August).
Weather also has a strong influence on people’s feelings.Winter may be a bad time for thin people.They usually feel cold during these months.They might feel unhappy during cold weather.But fat people may have a hard time in hot summer.At about 18℃, people become stronger.
