★3. hardly ever 几乎从不
hardly， 副词 几乎不，几乎没有。本身具有否定含义。放于连系动词be、情态动词之后，实义动词之前。也可用来回答 how often引起的特殊疑问句。

★4. once a week 一周一次
(1) once 副词 ①一次 ②曾经；从前
e.g. He visited his grandparents ___________.(一月一次)
翻译:那个男人曾住在广州_________________________________________________
【拓展】 once 的固定搭配：at once 立刻，马上 once or twice 一两次 once again 再一次
【注意】 一次：once 二次：twice 三次或三次以上：基数词+times
e.g. 三次：__________ 十五次：_____________ 许多次：____________
(2) 表示频率的常用表达：①次数+a+day/ week/ month/... e.g. once a day
②every+day/ week/ month/... e.g. every day
★5. ...next week is quite full for me... ······我下周相当忙······
full 形容词 ①忙的，同义词_____, 反义词______
e.g. Go to bed. You have a _____ day tomorrow. 睡觉去吧，你明天的事情排得满满的。
②满的，充满的 反义词_____. (be) full of... 充满......的；装满......的
e.g. The bottle ___ _____ _____water. 瓶子里装满了水。
③饱的，反义词是________ e.g. 翻译：I' m so full that I can hardly move.______________________
★6. How come 为什么呢？/ 怎么会呢？
相当于“Why / Why is it / For what reason or purpose ”，用于询问某事为什么会发生，或者为什么会有某种情况存在，可以单独使用，也可接陈述语序的句子。
e.g. _______________ you didn't wait for me 你为什么不等我？
【注意】why 也可表示“为什么”，但后用疑问语序构成疑问句。
