(p10-2d) full在此处意为“忙的”。He was too full to find time for hobbies. 【直击考点】 1）adj. full 还可译为“满的，充满的”。 反义词是empty，意为“空的”。 Hotels are often full at this time of year. 拓展：A be full of B. = A be filled with B “A中充满了B” The room is full of students. The bus is full of people. 2）full adj. “饱的”。 其反义词是hungry，意为“饥饿的”。 Are you hungry or full? I can't eat any more. I am quite full. 2. maybe adv. 大概；或许；可能 教材原句：I go to the movies maybe once a month. (p11) 【直击考点】 1） maybe 常放于句首，引导的句子是完整的。如：Maybe he knows Tom. 2） 辨析：maybe 和may be maybe “也许，大概，可能”。（副词） Maybe you are right. may be “可能是，也许是”。 为“情态动词+be动词”结构。（位于句中，充当系动词） You may be right. 3. health n. 健康；人的身体（或精神）状态 教材原句：She says it’s good for my health.
