A cloud forms in the jar! Some of the hot water in the jar turns into water vapour(水蒸气).The water vapour rises and meets the cold air commna off the ice cubes.When the water vapour condenses, it forms a cloud.

The word has also become people in foreign countries is an example of China's spreading influence in the world. This spreading influence is shown not just in economy(经济), but also society and culture. People are paying attention to picking up some Chinese words. Those words express special Chinese ideas.
The OED is also thinking about adding hukou and dama to the 120 Chinese words that makes sure Chinese people can live in a certain place, and dama means middle-aged Chinese women who influence the global gold markets because of their gold-buying habits.
The news that the OED will include these Chinese words has been criticized (批评).Some people say the words can be embarrassing(使人尴尬的)to some people in China, but others think that it's。natural for words to spread and”“used in. other places. In fact, the word tuhao expresses the humor or China. it is easy to pronounce and it makes nun of rich people who have more money.
So, welcome to the English language, tuhao--let's be friends!

Many Chinese children are often asked what they want to be when they grow up. 1000 boys and girls aged between two and twelve in the UK have been asked the same question recently. The result shows the future health of Britain is in safe hands- Most children chose doctor as the best job, ahead of(在……前面)teacher, actor and scientist.
The research was conducted by Mothercare, a British retailer(零售商)which specializes in (专门经营)products for mothers-to-be(准妈妈)and children up to 8 years old. While it shows most children dream of becoming doctors when they grow up, nurse,firefighter and musician,have also made the list of top ten jobs. Surprisingly, more boys dream of becoming dancers than girls while girls like football boots better than ballet shoes.
When they were asked what was the most important part of a job, many children(34%).said that "having fun" and "helping others" were more important than being rich and famous. It explains why only 1% of the children wanted to be a celebrity(名人)or reality TV star. 8% of boys said that they would most like to become dancers,perhaps taking inspiration(鼓舞)from some popular TV dance competitions such’as Strictly Come Dancing and Got To Dance.
However, lawyer did not appear on any of the lists. As you know, lawyer was a popular choice for children in the past.
The survey marks the launch(启动)of Mothercare's "Born To" series' for Save.the Children.Save the Children is the world's, independent charity for children in need. For every item in the "Born To" series sold. Mothercare will donate￡1 to the charity.
