Have you ever heard about any special plants?,Language Points,when it comes to 這個是固定結構，意為“當提到……；就……而論”，這里的 to 是介詞，所以后面是動詞的時候，要用V-ing形式；如果后面是名詞，直接加就可以。如：,When it comes to laughing, this tree is really funny. 當談到笑的時候，這棵樹真的很有趣。,When it comes to politics, I know nothing. 當談到政治方面的時候，我什么也不知道。,hear sb. doing表示聽見某人或某物正在做某事；而hear sb. do意為“聽到某人做了某事”，是指聽到整個過程。如：,2. When people first hear it laughing, they are usually quite surprised and begin to laugh along with the tree. 當人們第一次聽到它笑時，他們通常都很驚訝，開始和數(shù)一起笑。,I often hear her sing. 我經常聽到她唱歌。,知識鏈接 與此相同用法的有： see sb. doing sth. 看見某人正在做某事，see sb. do sth.看見某人做了（做過）某事； watch sb. doing sth. 觀看某人正在做某事，watch sb. do sth.觀看某人做了某事。,3. This plant can live as long as 1500 years, so people call it a living fossil. 這種植物能活到長達1500歲，所以人們稱它為活化石。,as long as 表示“長達------之久；和------一樣長”。as…as結構，中間接形容詞或副詞原級，在否定句中，也可說成 (not) so… as。as long as也意為“只要”，注意引導條件狀語從句時，主句用將來時，從句用一般現(xiàn)在時態(tài)代替將來時態(tài)，即“主將從現(xiàn)”。如： This river isn’t so long as that one. 這條河與那條河不一樣長。,Exercises,1.
