Man has a big brain(脑). He can think, learn and speak. Scientists always say that men are different from animals because they can think and learn. They know now that dogs, rats, birds can learn too. They are beginning to understand that men are different from animals because they can speak. Animals cannot speak. They make noises when they are afraid, or angry or unhappy. Apes(类人猿) can understand some things more quickly than humans. One or two of them can learn a few words. But they cannot join words to make sentences. They cannot think like us because they have no language(语言). They can never think about the future. Language is a wonderful thing. Man can build a modern world because he has language. Every child can speak his own language very well when he is four or five, but no animals learn to speak. How do children learn it? Scientists do not really know. What happens inside our body when we speak? They do not know. They only know that man can speak because he has a brain.

    Giraffes are beautiful, smart and friendly. They have long legs and necks (脖子). They are so tall that they can grow up over 5 meters (米). So how do they sleep or drink?

    You may think it's difficult for them to sleep, but they have no such problems because giraffes don't often stop for a sleep. Giraffes just need to sleep about thirty minutes a day. When they sleep, they don't always lie down (躺下). They usually sleep for minutes at a time, because it's difficult for them to get up again. And it's a great danger to sleep in the wild (荒野). But the giraffes in the zoo sleep for about 4-6 hours every day. They usually lie down when they sleep.

    Drinking water is a big problem for giraffes because their long necks are too "short". To drink water, they must spread (伸展) their front legs in a difficult way. And in this way, other animals like Africa's big cats can easily hunt (猎食) them. So they usually get most of their water from the trees and flowers. Giraffes don't need to drink water very often. They can even drink no water for months!

China's Project Hope has s{#blank#}1{#/blank#} over 4 million poor students since it was set up years ago. Until today, the project has raised more than 10 billion yuan of d{#blank#}2{#/blank#} from many people. The money has b{#blank#}3{#/blank#} used in building more than eighteen t{#blank#}4{#/blank#} Project Hope primary schools. Over 4 million children can go to these schools. Project Hope knows that these children won't have a bright f{#blank#}5{#/blank#}if they get no education. Most of the primary schools and students helped by the project are in China's central and w{#blank#}6{#/blank#} areas which are less developed. Project Hope has helped build learning centres, libraries and training centres. It also helps t{#blank#}7{#/blank#} school teachers from rural(乡村的) areas. Project Hope has been the largest and most influential（有影响力的）welfare（福利）project of China. Though it has done a lot for them, there are still millions of students who are too p{#blank#}8{#/blank#} to receive education. More action should be taken to h{#blank#}9{#/blank#} them. Project Hope needs more people's help and we can support its work by s{#blank#}10{#/blank#} donations.

Different countries have different rules on doing business. When there is a chance for you to go abroad for a business purpose, it is best to be clear about the rules and customs. {#blank#}1{#/blank#}

In Brazil

Brazilians are warm and friendly. They often stand close when talking and it is common for them to touch the person on the shoulder. People often greet each other (especially women) with light kisses.

{#blank#}2{#/blank#} Business meetings sometimes start later than planned. But to be safe, be on time. Meals can last for hours there's no such thing as rushing a meal in Brazil. Brazilians are social, preferring face-to-face communication to mails or phone calls.

In Singapore

Singaporeans shake hands when they meet and often also greet each other with a small, polite bow. Business cards should be offered and received with two hands. {#blank#}3{#/blank#} This is because arriving late is considered impolite.

In Switzerland

The Swiss call each other by their last name. They are also respectful of private lives. {#blank#}4{#/blank#}

For example, asking about a lady's age or how much they make a month is seen impolite. Being on time is required. Arrive at any meeting or event a few minutes early to be safe. They al-so have clear structure in their companies. Higher-ups make the final decisions, even if others might disagree.

{#blank#}5{#/blank#} They keep their hands be seen at the table and their arms off the table. It is polite to finish the food on your plate.

Please remember, when in Rome, do as the Romans do.

Earthquakes happen without warnings. But {#blank#}1{#/blank#}(not worry) because most are so weak that you won't feel them. Only a few big ones hurt people. However, it's very important{#blank#}2{#/blank#}(know) what to do when an earthquake happens. Let's learn some. 

● Don't go outside. You could get hurt from {#blank#}3{#/blank#}(fall) glass, windows or furniture. If you are outside, stay away from{#blank#}4{#/blank#}(build) and power lines. 

● Stay under strong furniture. Hold onto it. Or stay in a corner of the room. Cover your face and head {#blank#}5{#/blank#} your arms and cover your mouth with a towel(毛巾) or clothing. Don't go outside {#blank#}6{#/blank#} the shaking stops. 

● Keep away from falling things. Most people get injured (受 伤) by falling things during {#blank#}7{#/blank#} earthquake, not by the shaking itself. So {#blank#}8{#/blank#} (not stand) too near to something that could fall and hurt you. 

● Stop and stay inside your car. If you are driving when an earthquake happens, stop the car if it's safe. Stay inside your car until the earthquake stops, and {#blank#}9{#/blank#}(not drive) near bridges. Try {#blank#}10{#/blank#}(not stop) by power lines or trees. These might fall and hurt you. 

Many students find it hard to make good friends. To solve the problem, I plan to share my advice. 

Find chances to meet people. For example, sit somewhere with others when you are at school, especially at lunchtime. It doesn't have to be a crowded table, but try to choose one with at least two other people. Remember: Friends never knock on your door when you stay at home. 

        ▲   Joining in club activities is a great way to find other people who have the same hobbies as you. If you enjoy listening to music or singing, joining a music club is a good choice. More importantly, you can make friends there. 

Volunteer(自愿) for a group you care about. By working together, you can build friendships with others. You may spend your time at a hospital helping the people in need with other warm-hearted friends. 

Why not try these pieces of advice from now on?
