X. Read the passage carefully, then choose the correct answer — a,b,c or d.

Most people are afraid of sharks, but they usually do not know much about them. For example,
there are about 350 species of sharks that live in oceans over the world. All of the sharks are
carnivores, but most of them don’t attack people. Some sharks are very small — the smallest shark is
about 6 inches long — about as long as your hand. But some sharks are very large. The largest
species of sharks may be 60 feet long and weigh 15 tons. Unlike many other kinds of fish, sharks do
not have bone. Their bodies are made up of a kind of tough white flexible material (called

cartilage). Sharks do not have ears. However, they ‘hear’ sounds and movements in the water. Any
sound or movement makes the water vibrates. Sharks can feel these vibrations, and they help the
sharks find food. Sharks use their large eyes to find food, too. Most sharks see best in low light.
They often hunt for food at dawn, in the evening, or in the middle of the night.
Nowadays scientists want to learn more about sharks for several reasons. For example, cancer is
common in many animals, including people. However, it is rare in sharks. Scientists want to find
out why sharks almost never get cancer. Maybe this information can help people prevent cancer too.
1. According to the passage, sharks.............
a. are big mammals
b. usually live in warm water
c. are meat eaters
c. always attack humans.

DOLPHIN
dolphins talk? Maybe they can't talk with words, but they talk with sounds. They show their feelings
sounds. Dolphins travel in a group. We call a group offish a "school". They don't study, but they

travel together. Dolphins are mammals, not fish, but they swim together in a school.

Dolphins talk to the other dolphins in the school. They give information. They tell when they are happy
or sad or afraid. They say "Welcome" when a dolphin comes back to the school. They talk when they
play. They make a few sounds above water. They make many more sounds under water. People cannot
hear these sounds because they are very high. Scientists make tapes of the sounds and study them.
Sometimes people can catch a dolphin for a large aquarium. (An aquarium is a zoo for fish.) People can
watch the dolphins in a show. Dolphins don’t like to be away from their school in an aquarium. They are
sad and lonely. There are many stories about dolphins. They help people. Sometimes, they save
somebody's life. Dolphin meat is good, but people don't like to kill them. They say that dolphins bring
good luck. Many people believe this.
