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!

    InEngland, people often talk about the weather because you can experience fourseasons in one day. In the morning the weather is warm just like in spring. Anhour1 black clouds come, and then it rains hard. Theweather gets2 cold. In the late afternoon the sky will beclear, the sun will begin to shine and it will be summer at this time of a day.

    InEngland, you can also have summer in winter,3 have winter in summer. So in4 you can swim sometimes, and in summersometimes you should wear warm clothes.

    When yougo to England, you will see some English people take umbrellas or rain-coatswith them on the5 morning,but you shouldn't laugh at them. If you don't take an umbrella or a raincoat,you will regret later in the day.

How do you often get to school today? A recent survey by Weyview School Newspaper shows that Wayview students get to school by taking the bus, driving, riding a bike, walking and riding a scooter(滑板车). 

The survey shows that 25% of Wayview students take the bus to school. Fourth grade student Wesley Gibson said, "The bus is the best way to get to school. I can relax and talk with my friends while the bus driver does all the work." 25% of Wayview students get to school by car. Their parents drive them to school every day. 

The other 50% of Wayview students ride their bikes, walk, or ride scooters. 20% of Wayview students walk to school each day. Fifth grade student Alexis Wang is one of them. She said, "Walking to school is better because you do more sports."20% of Wayview students ride their bikes. Chris Madsen said, "he likes riding his bike because it's faster than walking."

The last group of Wayview students gets to school by riding scooters. More people ride scooters to school now. Last year, only 5% of the students rode scooters and this year it's 10%. Ellas Peterson said," Riding a scooter is the most fun way to get to school. It's cool. " But many students get hurt when riding scooters. Mr Smith, the headmaster of the school, advises that____. 

As you can see, Wayview students find all kinds of ways to get to school. It doesn't really matter how you get here if you get here on time. 

Almost all of us have had a flag raising experience.Hold it，then raise it.It's so easy.But doing so on the moon can be really difficult. 

There is no air on the moon，which leads to the first problem with flag raising—there's no wind to keep the flag flying. 

In the earlier Chang'e missions，the national flag of China was painted on the surface of the moon landers and rovers（月球着陆器和月球车）.In the Chang'e-5 mission，a special flag display system was invented.Since the Chang'e-5 didn't carry an astronaut to the moon，the work had to be done by a robotic arm.Researchers worked hard to make the display system weigh only 1 kilogram. The material of the flag is also a big problem.Normal flags on the earth would be broken or even destroyed quickly on the moon because of the radiation from the sun and huge temperature differences during the day and night. 

It took the researchers more than a year to find the ideal material.It was developed by Professor Xu Weilin and his team from Wuhan Textile University.It could help the flag keep its color and shape in the environment on the surface of the moon. 

The scene of the five-star red flag against the dark sky on the surface of the moon was taken by a camera on the lander and then sent back to the earth.Every Chinese was amazed at the history-making moment（时刻）.At the same time，we should also know and remember the teams behind this great effort.

Do you know any famous museums in the world？Here are three famous museums in different countries.

Some designers are trying to build a new type of house. The picture below shows some information about the house.
