V. Read the passage about Nick’s father’s unusual hobby and answer the questions.

My father has an unusual hobby; carving eggshells. As everyone knows, eggshells are very fragile. My dad can make beautiful pieces of art from empty eggshells. It's amazing. He started the hobby five years ago after a trip to the US where he saw some carved eggshells in an art gallery. My father did not go to class to learn how to carve. He learned everything from the Internet.

Some people say that this hobby is difficult and boring, but it isn't. All you need is time. It may take two weeks to complete one shell. I find this hobby interesting because carved eggshells are unique gifts for family and friends. I hope that in the future he'll teach me how to do eggshell carving.

IV. Read the passage and answer the questions.

The average life span of the Japanese is 78 for males and 85 for females, the longest in the world.
The main secret lies in their food. The Japanese eat a lot of tofu , which is made from soybeans. Tofu contains a lot of vegetable protein, calcium, and Vitamin B. It does not contain much fat, and it does not provide many calories.
Seafood like fish and vegetables play an important role in their diet, too. They cook the seafood with less cooking oil and less time. For each meal, they have more dishes on the table than us but they eat only a little of everything, never stuffing themselves.
Japanese people also work very hard and do more exercise. This helps them burn the calories off easily.
