　　In England winter is not very cold and summer is not very hot.There is not a great difference between summer and winter.Do you know why?

　　England has a mild(温和) winter and a cool summer because it is an island eountry.In winter the sea is warmer than the land.The winds from the sea bring warm air to England.In summer the sea is cooler than the land.The winds from the sea bring cool air to England.

　　The wet winds blow over England all the year.They blow from the southwest and also bring rain to England.So England has a lot of rain all the year.The west of England is wetter than the east.The winds must blow over the highland in the west.They leave more rain here.The east of England is drier than the west.

　　The four seasons are all three months long.Winter is in December,January and February.Spring lasts from March to May.Summer starts in June and goes on to August.Autumn is from September to November.

　　Scientists at the California Institute of Technology have reported evidence that Mars was warmer and wetter long ago than it is today．They say they have directly established(证实)the temperature of Mars four billion years ago．

　　The scientists say carbonate minerals(碳酸盐矿物)formed on Mars at about 18℃．They reached the finding after studying a meteorite(陨星)that had its beginnings near the Martian surface．Today, the average temperature on Mars is-63℃．

　　The finding was reported on the website of the Proceedings of the National Academy of Sciences．Assistant Professor Woody says 18°C is not especially cold or hot．He says this makes the finding extremely interesting．Knowing the temperature can give scientists an idea of the climate on Mars long ago．It can also help them decide whether the planet had water．

　　Geology Professor John was another writer of the report．He says knowing the temperature of Mars from long ago provides valuable information．It shows that early in the planet's history, at least part of Mars could support a climate like that of Earth．

I am going to take it into the house．”

　　He took the ice to his father and said,“This is a beautiful piece of glass, but it is very cold and wet．It was on a bucket of water in the garden．”Mr Robinson smiled and said,“Take it to the kitchen(厨房), put it in front of the stove(炉子)there, and dry(弄干)it．”The boy took the ice to the kitchen and put it in front of the stove．He dried(弄干)his hands, because they were very cold and wet, and then he went to the ice again．He looked at it, and then he took it to his father again．He said,“I put this glass in front of the stove, but it does not get drier．It becomes wetter and smaller．”
