【題目】 How can you tell when Valentine’s Day(情人節(jié)) is coming? All those heart-shaped chocolate boxes in the store are a good clue（線索）. So are those boxes actually shaped like the heart inside your body?

In fact, your heart is not shaped like a heart. It looks more like a peach. It is about the size of your fist（拳頭）. In most cases, it is in the left of your chest（胸口）. The human heart weighs about 250 grams. When a man is in a quiet state, his heart beats about 70 times a minute. When a person does very hard exercise, his heart beats can reach 150 to 180 times each minute.

The heart is one of the most important organs（器官） in the human body. It is made up of four “rooms”. When your heart contracts, the “rooms” get smaller. The main function （功能）of the heart is to provide pressure for blood flow and run blood to all parts of the body. When your heart relaxes, blood will come back into your heart and “rooms” get bigger.

Your heart keeps pumping blood throughout your body. It transports important nutrients to all the areas of your body. The health of the heart is very important to us. Please take care of your heart. Do you agree with my opinion?

【題目】 One cool April 22 morning, people started the day as usual. Yet it was not a normal day. What’s so special about April 22? The answer is because it is Earth Day. People all over the world celebrate this important day. The idea of having a special day to celebrate Earth began in the 1960s. Life was very different then.【1】 Most people had no idea how dirty our air and water were.

On April 22, 1970, twenty million Americans joined the first Earth Day activities. This showed that people really want to do something for the environment. Since then laws have been passed to protect the air, water, land, and animals. The vehicles (汽車) such as cars and buses you ride in must pass tests to make sure they don't cause too much pollution. Thanks to it, cars today give out about half as many bad chemicals as they did in the past.

【2】It's a good thing because they have got a lot of help. The Cuyahoga River in Ohio was so polluted that rubbish and oil on the river even caught fire! Today, the river is cleaner. It no longer burns.【3】

Now the celebration has spread to other countries. More than 175 countries take part each year. Every April 22, millions of people get together to clean and protect the Earth. 【4】 Our job is to put this knowledge to work. You can help keep our planet healthy, too!

A.They also celebrate how far we have come.

B.It's healthy enough for birds, fish, and other animals.

C.As a result, the air we breathe is cleaner than it once was.

D.Few people talked or even thought about the environment.

E.Rivers and lakes are also cleaner today than they were before.

F.Many animals near and in the river come back again after that.

【題目】 Once there was a poor young musician. He played the violin well, but he couldn't make enough money to buy much food to eat.

One evening he was eating a little rice and fish for his only meal—supper. A thin white cat came up beside him and the cat looked very hungry. Feeling sorry for the cat, the musician gave it his rice and fish, while he went to sleep hungry that night.

The next evening, there was a storm. The musician took shelter（躲避）under a large tree next to a big house. Thunder made a loud noise and lightning lit up the sky.

The musician looked toward the house and the warm lights inside. On the doorstep sat the white cat from the night before. It raised a small white paw(爪)as if to beckon（召喚）the musician to come over! Then he ran into the yard. A man opened the door and invited the musician inside.

Minutes later, a large branch fell to the place where he'd been because of the lightning. Inside the house, the musician ate a delicious meal with the man. Then the man asked the musician what was in his case, and the musician took out his violin and began playing. The man clapped with pleasure. "Luck has brought you here tonight!" he said. "I'm thinking of starting a band, and we need a violinist. Would you like to join us?" "I can begin tomorrow!" the musician said.

【題目】 Early rising makes people able to plan the work for the day. We can’t work well without a good plan. Just as the plan for the year should be made in the spring, the plan for a day should be made in the morning. Early rising gives us enough time to get ready for our work, such as to wash our hands and eat our breakfast. So the popular saying says, “Early to bed and early to rise makes a man healthy, wealthy and wise.”
