烦恼时，友情如醇绵的酒；痛苦时，友情如清香的茶；快乐时，友情如轻快的歌；孤寂时，友情如对饮的月…… 友情是一汪温泉，是共同烦恼和喜悦的点点滴滴，最后汇聚成一条友情的河，在生命里潺潺不息。
友情是一缕轻柔的风，是懊恼时送来的缕缕畅意，是烦闷时真诚互吐的心曲，是节日时互赠的声声祝语……那时的友情，是一卷明朗的画，无论何时想起都清爽亮丽；是生命里郁郁葱葱的树木，一年四季常青。 一个人的天空是狭小的、单调的。友情织成的天空，是广阔的，也是灿烂的。友情能给你的生活增添情趣，让你更多的洞悉外面的世界。 友情是一股互助的动力，是互相欣赏的知己。是成功时的互相致意，是失败时永恒的鼓舞，是一曲豪迈的歌，何时唱起都激昂如昔。 友情，又像是一杯浓浓的咖啡，是成熟后的淡淡的香醇与苦涩，是愚人节一个善意的玩笑，是生日时的那一句：生日快乐！ 你是天上的云，我就是吹动你的风，我们彼此依赖，互相信任，互相关心。 友情，有时是一种无声的陪伴，是桌子前的两两对坐，无言亦是懂得。友情是一处温暖的海港，静静地接待疲惫的你靠岸。

英语语法课件之强调句_(ppt)
-------强调句型二、强调句型的判断把“It, be，that”去掉，如果剩余部分句子结构仍然完整（被强调部分要还原到原位置），那么这个句子就是强调句；如果句子不完整，则不是强调句。
如：（1）①It is he who / that often helps me with my English.②It is on the hillside that we plant trees every year.③It was because of bad weather that the football matchhad to be put off.(Shanghai 2003, spring)分析：去掉It is / was... that / who 句子后结构仍然完整，句意仍明确，都是强调句。
④ It was 9 o'clock when we came back．我们回来时是九点钟。
⑤ It was 3 hours since we had come back．我们回来已三个小时了。
分析： 在上面例句中若去掉It was... when / before / since等后，句子结构就不完整，所以不是强调句。
2） ① It was at the theatre _________ Lincoln was murdered. It was the theatre _________ Lincoln was murdered. A. which B. that C. where D. the oneC B② It was our teacher ________did the experiment in the lab last night.A.whomB. thatC. whichD. where③ It was ten years ago________ Miss Gao returned toChina.A. thatB. whenC. sinceD. as④ It was ________ he said ______disappointed me.(Shanghai'99)A. what; thatB.that; thatC. what; whatD.that; what ⑤ It was for this reason ________ her uncle moved out of New York and settled down in a small village. (Shanghai2001, spring)A. whichB.whyC.thatD.howB A AC三、强调句型几注意首先，我们按强调句的语序来总结强调句的五项注意：1. 句首词用“It”，不能用“This”，“That”等。
