高二英语第十九单元A Freedom Fighter,
句意为“ — 我什么时候来取像片呢?我可是明天下午需要这些像片。”“ — 像片想必会在 ( 明日中午 ) 十二点以前洗出的。”正确选项为 B。情态动词表示推测，语气由强到弱的是：must ( 一定会 ) →ought to / should ( 想必会 ) →can / could ( 可能 ) →may / might ( 也许，或许 ) 。
2 . could 后接完成式常表示“ ( 过去 ) 可能……”，但也可用来表示责备语气，意为 “过去 ) 本来能够……， 而实际上却未…… ”。如：
— We could have walked to the station ; it was so near .
— Yes . A taxi _____ at all necessary . ( NMET92 )
A . wasn\'t B . hadn\'t been C . wouldn\'t be D . won\'t be
该题虽是一道考查动词时态的考题，但从“We could have walked to the station”可知，实际不是步行去火车站的。结合下句可知是坐了出租车去的，时间是过去，故正确答案是 A。

(2) demand that + (should) 。
(3) sth + be required to do (不能用demanded )
(4) sth require / want / need + doing = sth require / want / need + ing
(5) make a demand for要求…… 。 in great demand大量需求。

5. usual , common , ordinary 的用法
〖点拨〗三者都可用来描述每天发生的事，或被大多数人接受为正常自然的而不是新奇的事件。
usual 意为“通常的，寻常的，通例的”，用于修饰经常、固定或有一定的时间间隔重复发生的事，即有一定的规律性。
它可修饰符合自然规律的事物，也可修饰符合社会风俗或个人习惯的事物，侧重于一贯如此，遵循常规，并非新奇等含义。如：
Thunder is the usual sign of an approaching storm .
The following Thursday she went out at her usual time .
common 含有“平常，普通，常见，不足为奇”等意思，侧重于缺少显著或异常的特征，特别说明某物因司空见惯而普通。如：
Colds are common in winter .
A dog is one of the commonest pets .
This flower is common in spring .
ordinary 意为“正常的，通常的，平常的，普通的”，指由于与常规、习惯、一般标准或品质相同而普通，无特别惊人的性质。如：
