?Step4:师生互动、展示提升

互动三:知识点展示大比拼
知识点一:Flowers, leaves and stems grow above ground.
【词语辨析】on/above/over
On一般表示“在……的上面”(既垂直又接触),与beneath相对;
Over一般表示“在……的正上方”(垂直但不接触),与under相对;
Above一般表示“在……的上方”/“比……还高”(既不垂直又不接触),与below相对。
注意:above还可指数量、重量、度数、山岳的海拔高度等方面超过或高于规定的数量或一般标准
Eg:Today's temperature is above 39℃。
【小试身手】用on、over、above填空
1 We can see a new bridge < > the river.
2 The plane is flying < > the clouds.
3 They planted many trees < > the hill.
知识点二:Plants have flowers because the flowers make seeds.
Because是连词,意为“因为”,引导原因状语从句,就其引导的原因状语从句提问要用why。
【英汉差异】在英语里表达“因为……所以……”时,只能分别用because或者so,二者不能同时使用,这一点与汉语不同,值得注意。
Eg:He didn't go to work because his wife was ill.
= His wife was ill, so he didn't go to work.
知识点三:New plants grow from seeds.
知识点四:The seeds of the rice plant feed billions of people.
hundred/thousand/million/billion用法小结
【词语辨析】hundred & hundreds of
1. 当hundred作为数词或表示具体的数量时,前面可用其它具体数词来修饰,后面直接跟名词。
There're two hundred monkeys in the hill.
2. 当hundred用于表示不确定的数量时,其后加s,即hundreds, hundreds of 成百的,数以百计的。前 面可用some,a few,several等词来修饰。hundreds 后面加of再加名词。
hundreds of dollars几百美元
I think there're hundreds of children in the kinder garden.
我看这个幼儿园大约有几百名儿童。
类似的搭配还有thousands of 数以千计的;millions of 数以百万计的;无数的。 象hundred,thousand,million,billion等量词,在用法上都遵循这一点。
