知识点拨

考点 01  How often...? 询问频率与次数表达

How often do you have sandwiches?  你多久吃一次三明治？

Twice or three times a week.  一周两三次。

▸ How often...? 用于询问做某事的频率，回答用次数 + a week 等时间短语。

解析：How often 用来询问“多久一次”，是询问频率的特殊疑问句。主语是 I、you、we、they 等时用 do 引导；主语是第三人称单数时用 does 引导。回答常用 once（一次）、twice（两次）、three times（三次）等 + a week。

一、How often 的问法：do / does 的选择

主语是 you、they 等时用 How often do you/they...?；主语是 he、she 或一个人名时用 How often does he/she...?

例句：How often do you drink soya milk? 你多久喝一次豆浆？

例句：How often does James eat bread for breakfast? 詹姆斯多久吃一次面包当早餐？

二、频率回答：Once / Twice / ... times a week

once a week 一周一次；twice a week 一周两次；three times a week 一周三次。

例句：—How often do you have sandwiches? —Once or twice a week. —你们多久吃一次三明治？—一周一两次。

三、次数的表达规则

一次用 once，两次用 twice，三次及以上用“数字 + times”：three times, four times, five times。

例句：I read English five times a week. 我一周读五次英语。

⚠ 易错提醒：three times a week(√) three time a week(✗) 三次及以上要用“数字 + times”！

考点 02  would like to have ... 表达想吃的食物

I would like to have baozi for breakfast. How about you?  我早餐想吃包子。你呢？

▸ would like to have ... 表示“想要吃（喝）……”，语气礼貌委婉。

解析：would like 意为“想要”，后面接 to + 动词原形。have 在这里表示“吃；喝”，would like to have + 食物或饮品，表示想吃（喝）什么。

一、would like to have + 食物 / 饮品

表示想要吃或喝某种食物。
