注意:1.fish的“数”
用法 fish作“鱼肉”讲时为不可数名词
图解
fish指“鱼的条数”时,单数和复数同形,即 fish
fish指“鱼的种类”时,其复数形式是fishes
例句 I like to eat fish.我喜欢吃鱼。
There are 2 fish in the fish tank.鱼缸里有两条 鱼。
名词作定语强调“类指”,而名词所有格则表示“特指”
Please don't put the dog's food under the table.请不要把狗食放在桌子 下面。(特指给某一条狗的食物) Dog food costs as much as meals.狗的食品和人的食品一样贵。(指类 别,即供狗食用的食品)
