There is a zoo in my town. I often go there with my parents by 1 on the weekend. It usually takes my father about 2 minutes to drive there. We often leave home at about eight and 3 there at about twenty past eight.

    I like many kinds of animals, but I like  4 best. First, they are very cute. Second, they are friendly, and they are one of China's 5. but now pandas are in great danger, so we must  6 them.

    Now, I'm watching the two pandas in the zoo. I  7 want to go near and play with them. 8 I also want to give them some food. But 9 the rules in the zoo: 1. Don't go near tothe animals. 2. Don't give10 to the animals.

    To make animals live a happy life, everyone needs to follow the rules.

    Although cats may be one of the most popular pets today, little is known about how and when humans and cats set up their close relationship.

    The earliest evidence for human–cat interaction dates back to prehistoric Cyprus(史前塞浦路斯), where the remains of a wild cat and a human — dated 9,500 years old — were found buried together

A new study in the Proceedings of the National Academy of Sciences has confirmed the first direct evidence of a human–domestic cat relationship among Chinese farmers 5,300 years ago. Researchers studied the bones of cats, dogs, deer and other animals unearthed in an excavation (挖掘) near a village in Central China. By using some ways, scientists showed that the cats were living on a mostly millet(黍)–based diet, just like the domesticated dogs and pigs from the site.

"The most reasonable explanation for a high consumption of millet–based food is that the cats had formed a stable and mutual relationship with humans and could easily feed on rodents (啮齿动物) around human villages, find leftover food or even have been fed by people intentionally," said Hu Yaowu from the Chinese Academy of Sciences in Beijing, whose research focuses on the relationship between humans and domesticated animals.

    "It is very interesting for us to find the consumption of millet-based foods by the cats, since this kind of evidence had long been missing.” Hu explains. Since cats usually eat meat, such a diet would be unexpected, unless the cats were being fed by people, the study argues. The researchers also found that one of the cats survived to reach old age, implying that it had a safe place to live and enough to eat.

Why the farmers wanted to keep cats nearby or make them "pets" could be answered by other evidence. Chinese archaeologists found some storage containers were specifically designed to keep out rodents — a vermin (害兽) that cats could certainly have helped with.

The simplified theory is that rats were attracted to the food of farmers, and so were harmful to farmers. Cats were attracted to the rats, and so farmers formed a mutually beneficial relationship with cats, taking care of them in return for pest control.

"Can I have a glass of hot water?" This is a very common question in a restaurant for many Chinese people, nothing is more common than drinking hot water every day. However the simple habit is hard for people from other countries to understand. 

For many Westerners, the idea of drinking hot water is very strange. However, most Chinese people think the Americans' habit of drinking ice water is also strange and even unhealthy. Some old people in China would carry a kettle(水壶) when they travel. Chinese doctors advise more people to take on the habit of drinking hot water especially for women. 

But in Western countries, drinking hot water isn't common. Westerners often have drinks with ice, not just on hot days but almost every day. 

There is a story online about an American who has been in Beijing for over five years. He visited a local restaurant after going back to America. He asked for a glass of hot water, but this request(要求) surprised the waitress, "To...to...to drink?" she asked him. Finally the man received the hot water but felt cold stares from every corner of the restaurant. 

Westerners wonder why Chinese people drink hot water as Chinese wonder why Westerners drink cold water. This cultural difference is not a simple problem, but related to(与......有关联) history, culture and science. 

As a matter of fact, many Chinese teenagers now like bottled water for daily drinking. With teenagers growing up, will drinking hot water become a less popular life habit in China?

Singapore is a small island nation in Southeast Asia. Singapore is both the name of the country and its capital. It is said that a prince named the Island Singapore, meaning "Lion City". It's also called "Garden City" because gardens and trees are everywhere. Singapore Island and about 60 small islands make up the country. Almost 5,630,000 people live there. That makes Singapore one of the most crowded countries in the world. Most people speak English, but Chinese, Tamil (an Indian language) and Malay are also official languages. What's more, it is very hot and often rains in Singapore. 

What is your favorite colour? Does it make you feel happy or relaxed? Some people think colours have a connection with(与…有联系) their feelings(情感). This may be true. Scientists ask 26,596 people from 100 countries about their favorite colours and why they like them. 

Many people think blue is a cool colour. Blue clothes can help you feel relaxed. And the colour blue can make people not eat too much. If you don't want to be fat, you may try to eat at a blue table. Blue can also mean sadness. When you are unhappy, you may say "I'm feeling blue". 

Yellow is the colour of the sun. It's a warm colour. When you walk in a yellow room, you may feel warm and comfortable. Many people like orange because it is also a warm colour. In factories(工厂), orange is the colour of workers' clothes. It can help them work better. 

How about green? When you do your homework for a long time, just stand up and look at the trees outside. You may feel better. 

Purple usually makes people think of beautiful things. On your mother's birthday, you can buy her a purple sweater as a gift. 

①What will you do if you see a cockroaeh(蟑螂) ? Quite a few people are very afraid of it, so they may shout for help or try to kill it. Next time you see it, you may need to think twice before killing it.

②There were cockroaches on the earth long ago, and many people believe that they will still be here long after all the people leave it. Cockroaches are small in size, and they are good at climbing and jumping. A cockroach can live for about a week without a head. These make them great helpers during the search and rescue missions(搜救任务).

③Alper heads up led a scientist team at North Carolina Stage University. "I joined the search and rescue missions in Turkey in 1999, "he said. "One of the most difficult problems was to find where the living people were. We needed to find them in a short time, but there was no useful way to help us at that time. "So Alper and his team had the idea of turning cockroaches into special robots.

④Scientists put a small sensor(传感器) and a smart camera on a cockroach's back. Cockroaches climb everywhere with them, With a sensor and the camera, cockroaches can tell people from other things, and then find where the missing people are. In this way, more people can be saved in time.

⑤All in all, the scientists hope these special cockroach robots will be used for more work over the next five years. "We never thought we would see the day, but here we are!"a scientist said.
