Lesson20 教材知识详解1. Danny, I have to go to the supermarket. 丹妮，我得去超市。

have to表示在有外来压力的情况下“必须；不得不”，后接动词原形，可用于多种时态。

如：She had to look after her sick mother yesterday.昨天她不得不照顾她生病的妈妈。

(l)must为情态动词，也意为“必须”，表示说话人的主观看法，语气很强硬。

如：You must be careful! 你必须小心！(2)must的否定形式不能用don’t must，它和may，can这类词一样，要在后面加上not。

如：You mustn’t take the books out.你不准把书拿出去。

2. It’s full of delicious food. 它充满了美味的食物。

be full of为固定短语，意为“充满”。

(l)be filled with意为“装满了……”，相当于be full of，表示一个状态。

如：The bag is full of books.=The bag is filled with books.包里装满了书。

(2) fill...with…的主语通常是人，意为“用……装满……”，表示一个动作。

如：He filled the bag with clothes.他用衣服把包装满了。

food为名词，意为“食物”。

如：Do the twins like Chinese food? 那对双胞胎喜欢中国食物吗？(l)food意为“食物，粮食，（与饮料相对的）食品”时，为不可数名词。

(2)当表示特定种类的食品时，food可以作可数名词，其复数形式是foods。
