Look, listen and say

There are twenty ducks.
I see a bird in the tree.(我看到树上有一只鸟。)
★see“看见”，bird“鸟”，in the tree“在树上”。
注意区分：on the tree修饰的是原本就长在树上的东西，如树枝、树叶、花、果实等。in the tree修饰的是原本不在树上，后来被放置或挂在树上的东西，如鸟、猫等小动物，物品及人，或者是其他装饰品。
How many ducks are there (有多少只鸭子？)
★“how many多少”用来修饰可数名词的复数。“How many…are there”是用来询问某处有多少人或物的句型。
★“How many…are there”的基本用法是：How many+可数名词的复数形式+are+there+地点/时间状语？回答通常用“There are+基数词+可数名词复数+地点”，或直接回答“具体数字”。
There are some birds in the river.(河里有一些鸟。)
★“There are some…in the…”是英语中的一种常见句型，用于表达“某地有某物”。
★“There are some…in the…”的基本结构是“there”+“be动词(are) +“some”+复数名词+“in the”+地点状语。
