Rock climbing(攀岩)did not become a sport until in the late 19^th century. {#blank#}1{#/blank#} 

While rock climbing may still be necessary for mountain climbing, most people just climb low mountains for fun.

    If you have ever done rock climbing, you will know that it is not a very easy sport. {#blank#}2{#/blank#} What most people don't know is that rock climbing is one of the sports that depend on your body and mind(意志).

    To climb successfully, one must use wonderful skills. {#blank#}3{#/blank#} Another important rule is that your arms only hold you close to the rock face while your legs are pushing you up. The closer you are to the rock face, the easier it is to climb.

{#blank#}4{#/blank#} Once you start to learn how to climb, you'll find more fun. People who like games such as chess playing or problem—solving may love rock climbing, because they are nearly the same in the way of thinking. {#blank#}5{#/blank#} Anyone who enjoys a difficult game and loves the outdoors should think of taking rock climbing as a new hobby.

    Jack is my best friend. He is in a new school. He likes it very much. It's not far from his home. And it usually takes him 10 minutes to get to school by bike. School begins at 8: 00 every morning. But these days Jack is often late for school. This morning, he is late again. The teacher is very angry.

    "How do you usually come to school?" asks the teacher. "By bike." Jack answers. "What time do you usually get up?" "At 6: 30." "Well, it's not late. What time do you usually leave home?" "I leave home at 7: 55." "Why not leave home earlier?" "My mother is ill (生病的). She stays in bed all day. I must look after her and give her medicine at the right time， so I'm often late for school," says Jack with tears (泪水) in his eyes. "I see, Jack, you are a good boy!" says the teacher.

Should We Help Strangers?

Recently our class had a discussion about {#blank#}1{#/blank#} we should help strangers or not. Different students have different {#blank#}2{#/blank#} (idea).

Some think {#blank#}3{#/blank#}we should try to help strangers. Helping others is a virtue (美德), and helping others is helping {#blank#}4{#/blank#} (we). We may come across some trouble and need others' help some day. If everyone isn't willing to help us just {#blank#}5{#/blank#}we are strangers to them, it's hard to imagine {#blank#}6{#/blank#} our world will be like.

However, some worry {#blank#}7{#/blank#} helping others can sometimes bring us trouble. Sometimes we are just misunderstood and even have to pay the cost of kindness.

In my opinion, we should try our best {#blank#}8{#/blank#} (help) others when they are in need of help, but we should also avoid {#blank#}9{#/blank#} (get) into trouble. If everyone tries a little kindness, our world{#blank#}10{#/blank#}(be) full of love.

Health problems which are related to climate change are getting worse, say two research reports.

The report s followed 44 health problems that are related to climate change around the world. They include heat deaths, infectious diseases（传染病）and hunger. "All of them are getting worse," said Marina Remanello. She is research director of the Lancet Countdown project. "With global worming getting worse, doing nothing on climate and health will cost more than acting now, one of the reports says.

The reports are called "code red for a healthy future". One report is centred（集中）on the US and the other is centred on the whole world. The reports found some dangerous facts. At-risk populations like older people and the very young are more easily influenced by high temperatures. For people over 65, the researchers found they stayed living in warm places where it is easier for some diseases to spread. For example, coast areas are warm enough for dangerous bacteria （细菌）to grow. In some poor nations me season for disease-spreading mosquitoes（蚊子）has got longer since the 1950s.

The research also found that 72 percent of countries saw an increase in wildfires. And in 2020, up to 10 percent of the world's land surface was influenced by extreme（极端的）drought. In the US, the heat. fire and drought caused the biggest problems. The Pacific Northwest and Canada saw extreme neatwaves. An earlier study found that the heatwaves would not have happened if there were no human-caused climate change.

Mary is studying in a middle school in Shanghai. She likes Chinese {#blank#}1{#/blank#} very much because it is delicious. Today is the Dragon Boat Festival. Mary is watching the dragon boat race with {#blank#}2{#/blank#} classmates Alan and Henry. 

At noon, they all feel {#blank#}3{#/blank#} so they take a bus to a Chinese restaurant. They want to order (点餐) some Chinese food for {#blank#}4{#/blank#}. "I don't want to eat hamburgers. They are not {#blank#}5{#/blank#} for my health," Alan says. "I'd like some rice and chicken. What about you, Mary?" "Many Chinese say if you eat a dumpling with a coin (硬币), you can get good luck," says Mary. "We will have{#blank#}6{#/blank#}important test next Monday, so I'd like to have some Chinese {#blank#}7{#/blank#} to have good luck." 

"Haha! Mary," Alan says. "You can only eat them {#blank#}8{#/blank#} Chinese New Year." "Oh, I know, but now I want to{#blank#}9{#/blank#}some dumplings," Mary says. "And what would you like to eat, Henry?" 

"I'd like noodles," says Henry. "And I'd like some fish, too. It shows you will have lots of money {#blank#}10{#/blank#}fish sounds ‘yu' in Chinese." 

Sam is an eight-year-old student. He can't always have fun at school,1 he doesn't like his school. He is good at all his2 , but he doesn't have friends. Sam is not happy about that.3 a Saturday morning, Sam sees a big tree. 

A small blackboard is in 4 tree. It says, "I am a magic(有魔力的)tree. Say the right words to me and then I can 5 you."

Sam says many words but they are not useful. The tree6 say a word. At last, he says, "Please, dear tree! Thank you!" The tree says, "Sam，say7 more(更多) and then you can be happy."

After that, Sam often 8 "Please" and "Thank you" at school. His classmates think he is nice and they all want 9 his friends. Then Sam asks many of his classmates to come to his 10 birthday party. They all have a good time.
