A lovely rabbit, a cute hamster, some colourful fish, a strange-looking turtle or a snake...What kind of pet would you like? Lots of kids love animals and dream of having a pet.

    But not every family can have a pet. So, in many Western countries such as America, Britain and Australia, primary and middle school classes have their own pets. Looking after a pet is not as easy as you may think! Fish and turtles need clean water and the right food. Hamsters and rabbits need fresh vegetables and a warm place to sleep. Even little mice need good care! What would you feed a pet mouse? How about snakes?

    Class pets teach kids about nature and being responsible. Sometimes the pets have babies. It's very exciting but it also means having more animals to take care of!

    Students take turns to take care of their class pets. Every week the pets have a new “mum and dad” to look after them.

    You may want to know what happens to the class pets during school holidays. At the end of term, the teacher chooses a responsible student. This lucky student keeps the pets at his or her home for the holidays.

    Notes:

1) hamster n. 仓鼠   2) turtle n. 乌龟   3) responsible adj. 负责任的   4) choose v. 选择

Until the beginning of July, there has been no rain in northern Italy for over 100 days. Add to that the high temperatures, and the locals get very dry conditions. This is the most serious dry spell（干旱期）for that area in the past 70 years. Because of this situation, the country's longest river, the Po, is drying up!

This is bad news for several different reasons. The fresh water of the Po provides drinking water for northern Italy. Besides, farmers in this area need the water of the Po to keep their crops growing. What's more, the flowing river water is used to create about half of the hydroelectric power（水力发电）for Italy. Its drying up means that more natural gas（天然气） will be used, which is bad for the environment.

There have been some interesting discoveries from this lack of rain, however. Between Florence and Milan, a long ship sunk （沉没）in 1943 appeared because of the low water levels of the river. Now many tourists and locals come to see this ship. A German tank has also appeared out of water near Mantua. At other places along the river, people can even walk on the sandy river bed. Although this may be interesting, people in Italy and around the world are hoping for the return of rain to refill the Po!

Cinyee Chiu, an artist from Taiwan, is always happy to try something new. Her amazing works won lots of prizes. Among them, "24 Solar Terms (节气)" is the most popular.

Ancient Chinese divided a year into 24 parts according to the changes of the weather. It's the 24 solar terms. But not everyone knows them well. Cinyee Chiu put the 24 solar terms in pictures to help people understand them better.

Cinyee turned each solar term into an animal. But these animals are not just animals. You can also find seasonal fruits, vegetables or beautiful flowers on them.

When spring comes, water gets warm and fish start to swim around. So Cinyee chose fish as a symbol of Start of Spring. Also, she drew spring vegetables, Chinese chives (韭菜) on the back of the fish.

White Dew (露珠) falls on about Sept. 8. It shows the beginning of the cool autumn. There are colorful leaves and cooler nights at this time of year. As the temperature falls, white dew is often seen on the grass and trees at night. For White Dew, Cinyee chose a raccoon (浣熊)—a small animal with thick hair. She drew white spots (小圆点) on the raccoon to show dew. And she used the dragon fruit to show the rich colors in autumn.

The young artist really gave the ancient Chinese culture a new look.

Dogs really are man's best friends, and they are very useful in some ways. 

A new study said that dogs can smell(闻) if people are feeling stressed(有压力的). They can smell the difference in breath(呼吸) and sweat(汗液) from people. Then they can tell if people are. stressed or not. It could be 93.75 percent right! A study from scientists at Queen's University Belfast, UK, said this. 

Scientists got breath and sweat from people both before and after doing a hard maths problem. They looked at the people's heart rate(心率), blood pressure(血压) and stress level(压力水平) in the study. The dogs found stress in 675 of the 720 people, that is 93.75 percent of the people, reported Australian news. 

Stress makes people's breath and sweat different. Dogs can smell that difference, said the study's writer Clara Wilson. In the study, she also said this finding helps us know how dogs may know people's feelings. 

Dogs are always man's best friends, and they have special ability(能力), do you think so?
