以下内容制作 PPT，为第 10--13 页。
1）Have you ever grow any plants? If so, what did you do to grow them? If not, what kind of plant would you like to try growing? SS： （翻译）你种过植物吗？如果种过的话，你是怎么种的？如果没有种过 的话，你想要尝试什么植物？ T： （点拨）if so 为省略句，意为“如果是这样的话” ，if 用作连词，so 用来 代替上文内容，以避免重复。If not 为 if so 的否定形式。 2）In 1974, he became the first agricultural pioneer in the world to grow rice that has a high output. SS:（翻译）他成为世界上第一位种植高产水稻的农业先锋。 T： （点拨）to grow rice 是动词不定式作定语；that has---output 是定语从句， 修饰先行词 rice。 “the first +n.+ to do”意为“第一个要做------的------” 。不定式常 用在被序数词、最高级修饰的名词后作定语。而且这些名词与不定式有逻辑的主 谓关系。 3）This special strain of rice makes it possible to produce one third more of the crop in the same fields. SS： （翻译）这种特殊的水稻使得同样的土地多收获三分之一的粮食。 T： （点拨）本句中 it 作 make 的形式宾语，而真正的宾语为其后的不定式 to produce one-third more of the crop in the same fields, possible 在此处作 make 的宾语 补足语。一般的表达式为:make +it+宾语（to do/that） 。 4）Using his hybrid rice, farmers are producing harvests twice as large as before. SS:（翻译）用他的杂交水稻种子，农民种出的粮食比以前多了一倍。 T： （点拨）twice as large as before 是倍数表达方式。常用的倍数表达方式有： A is+倍数+as +adj.+as B +比较级+than B +the +名词（size, length, width, height）+of B +what 从句
