小博士：时间名词前可以用的介词在初中阶段学的主要有5个，可以用下面的速记歌来帮助学习。
年月之前要用“in”，遇到日期却用“on”。
上午下午又是“in”，某日上下午“on”帮忙。
正午、晚上用“at”，黎明、午夜也相宜。
时钟之前也是“它”，差分过秒不用“它”
说“差”要用介词“to”，说“过”要用“past”。
多说多练牢牢记，学好英语本事大。

What will the future be like?It’s possible that we may often fly up into space!Out of all the coolest inventions of the year, Time chose Spaceship One as the best．
Spaceship One is a 6-meter-long white spaceship．On June 21, American pilot Mike Melvill flew it to space and back-about 100 kilometers up into the sky．(1)Some might say it’s not a big deal．You know, people went to the moon years ago．
Well, Spaceship One is special because(2)it is the first spaceship that wasn’t made by the government．It was built and launched(发射)by a private US company．Lots of people want to travel in space．But it’s too expensive．American milliomaire Dennis Tito paid almost US ＄ 20 million to become the first space tourist to visit the International Station in 2001．So private companies began to think of making their own spaceship to take other tourists up into space．
(3)飞船一号的成功是一个好的开端。In the next 10 to 15 years, if you pay ＄20,000 to ＄100,000, you could fly high above the earth．

Our earth is in trouble．Our drinking water is becoming dirtier, and the air is not as clean as before．People and factories are polluting the air, rivers and lakes and seas．You may think that there is mothing you can do to help．That's not true．There are many things you can do to help the earth．
Cars burn gasoline．This will produce a lot of CO2 into the air．Some people believe that too much CO2 is making the earth warmer than ever．They think CO2 thins the clouds above us．The clouds keep us away from the strongest sunlight．So try to walk, ride a bike or take a bus．And if you drive a car, drive at a steady speed．This can save some gasoline．
The biggest energy use at home is for keeping warm and cool．So turn the air conditioner off when you don't need to use it．Use lights that save energy．
Use fewer things that cannot be used again．When you buy something, consider those made from things that can be used again first．
(1)要用大量的水来洗澡沐浴．In one week an American family uses as much water for showers as a person drinks in three years! Buy a waterworks that uses less water, or take shorter showers．This can cut the use of water．

小词典：大家一定记得以前我们学了one，two，three，four这样一组表示数目的数词，这类词叫基数词。这一单元我们学到了表示顺序的数词，如：first，second，third等，这类词叫序数词。每个基数词有一个对应的序数词。除了一些特殊的变化外，一般是在相应的基数词后加-th构成序数词。序数词前一般要加定冠词，如the first name(第一个名字，名)，the second day(第二天)，CharlesV 查理五世读作Charles the fifth.
