Jimmy was five years old and lived with his parents, the Watsons, in Smithville, in the southern United States. He loved his big black1, Big Boy. Last week, in the early hours of the morning, a strong smell suddenly woke Big Boy up2 his sleep. The dog got up and walked into the kitchen. There the smell and the heat grew stronger. Big Boy could 3that something was wrong, very wrong. He barked(吠)and ran up to the second floor. He barked and barked at the door of Jimmy's room,4there was no answer. Then he ran to Mr and Mrs Watson's room. He barked again, more loudly, and tried to5 the door. Mr and Mrs Watson didn't wake up. Big Boy ran back to Jimmy's room. He made as much6as he could.

    Finally, Jimmy came to the door and opened it. "Big Boy, what's wrong?" Jimmy said. Big Boy took Jimmy's 7 in his mouth and tried to pull him down to the first floor. "Big Boy, Big Boy, stop! Stop! What are you 8? Mum, Dad, come quickly! Help! Help!" Jimmy shouted loudly.

    His parents ran out of their room. They understood that there was a fire. They 9picked Jimmy up and ran out of the house. Big Boy ran after them. Just then, the fire came all the way up to the top of the 10. Big Boy saved the family! He's a hero today in Smithville.

A: Hi, Henry. You look so worried. What's up?

B: Hello, Jack. {#blank#}1{#/blank#} Many people hurt because of it.

A: Oh, I'm so sorry to hear that. Why did it happen?

B: {#blank#}2{#/blank#} And the weather was dry and windy at that time.

A: That's the point. {#blank#}3{#/blank#}

B: You are right. Safety comes first. Some children lost their home.

A: I want to do something for the children. {#blank#}4{#/blank#} 

B: Maybe you can make a short video to cheer them up. 

A: Our schoolmates can also help them, too. 

B: That's a good idea. {#blank#}5{#/blank#} 

A: Let's go and talk with him.

In the US, about 400,000 students are learning Chinese. Chinese is getting more and more popular there.

Murray is one of the Chinese learners. He became interested in Chinese tea culture when he was 12 years old. To learn more about tea and find the best tea, he started to learn Chinese.

Murray spent two years learning Chinese at the University of Pittsburgh." Those two years of study life were very busy," he said. He went to a class at 8 a. m. on weekdays. All students needed to speak Chinese in class. Every Monday and Wednesday he went to a grammar class at 2 p. m. For Murray, Chinese grammar is easy because the Chinese language has no tense(时态). But the pronunciation is really a hard part of the language. To improve it, Murray needed to practice Chinese four tones(声调) every day.

This week, we are going to learn about great inventions in the world. {#blank#}1{#/blank#} The inventions were trying to make something completely different. Here is one story. 

In 1945, at the end of the Second World War, Percy LeBaron Spencer, an American scientist, was working on a machine to produce powerful radio waves. {#blank#}2{#/blank#} The machine was able to cook things! Percy called it a microwave. {#blank#}3{#/blank#}However, the first microwave weighed around 350 kilograms and was as big as a fridge! {#blank#}4{#/blank#} Now millions of homes have microwaves. {#blank#}5{#/blank#}. So we can say that the microwave has changed the way we live. 

It is Sunday today. Lily and Wei Fang get up early(提早). After breakfast, they go{#blank#}1{#/blank#} in the clothes shop. There are some new clothes in the shop. Lily {#blank#}2{#/blank#} a red coat. It is nice. Wei Fang tries {#blank#}3{#/blank#} some clothes, they are all too big. So she doesn't buy {#blank#}4{#/blank#} clothes. But she buys a pair of {#blank#}5{#/blank#} for her mother. Her mother is very happy.
