四、重难点突破
What's this? 与 What's that? 的区别
What's this? 用来询问离自己较近的事物(近指),What's that? 用来询问离自己较远的事物(远指)。回答都用 It's a/an... 结构。this 指近处的「这个」,that 指远处的「那个」。
— What's this? — It's a tomato.(——这是什么?——这是一个番茄。)
— What's that? — It's an orange tree.(——那是什么?——那是一棵橘子树。)
【进阶训练】选择正确的疑问词:Look! _____ is a flower near me. And _____ is a tree over there.
A. This; that B. That; this C. This; this D. That; that
答案:A 离自己近的用 this(近指),离自己远的用 that(远指)。
It's a... 与 It's an... 的用法
在 It's a/an... 结构中,a 用在以辅音音素开头的单词前,an 用在以元音音素开头的单词前。注意是看发音而不是看字母,如 an orange tree(orange 以元音音素开头),a university(university 虽以 u 开头但发辅音/juː/)。
It's a carrot.(它是一根胡萝卜。carrot 以辅音/k/开头,用 a)
It's an orange tree.(它是一棵橘子树。orange 以元音/ɒ/开头,用 an)
【进阶训练】选择正确的选项:It's _____ tomato. It's _____ orange tree.
A. a; a B. an; an C. a; an D. an; a
答案:C tomato 以辅音音素/t/开头用 a,orange 以元音音素/ɒ/开头用 an。
leaf 的复数形式 leaves
leaf 的复数是不规则变化,变为 leaves,即 f 变为 ves。类似的词还有:wolf → wolves, shelf → shelves。注意书写时不要忘记把 f 变成 v 再加 es。
It has green leaves.(它有绿色的叶子。)
Look at the leaf. It's beautiful.(看这片叶子。它很漂亮。)
【进阶训练】选择正确的选项:The carrot has green _____.
A. leafs B. leaves C. leaf D. leafes
答案:B leaf 的复数是不规则变化,f 变为 ves,即 leaves。
