一、下面四组,每组短语之间有什么区别?有什么不同的含义?请详细解答并写出例句
1.以下一组词都用来提出建议,表示“最好”或者“以…为妙”,属于情态动词,用在动词原形前,had better 语气较 had best 弱.如：
had better：You had better go now.你现在走比较妥当
had best：You had best go now.你现在以走为上.
2.以下是一组复合情态动词的同义词,都表示“只能、只好、只得、不得不”,后面跟动词原形,意思大体相同,侧重面略有区别,其中的 but 是副词,含有“仅仅、只有、除了”的意思.如“我不得不改日拜访他”——
* can but：You can but visit him another day.（我能够而且也只能够改日拜访他）
* can’t but：I can’t but visit him another day..（我除了改日拜访他不能现在就去）
* can’t choose but：I can’t choose but visit him another day.（我除了改日拜访他别无选择）
* can’t help but：I can’t help but visit him another day.（我除了改日拜访他别无它法）
3.以下一组中的 than 有时候是跟名词作宾语的介词,有时候是跟其他语法成分的连词——
* rather than表示“与其...(宁愿...),胜于”,如：
He resigned rather than take part in such a dishonest transaction.他宁愿辞职也不愿意参加这样一种欺骗的交易.（不定式）
I would you came tomorrow rather than today.我宁肯让你于明天来而不是今天来.（副词：时间状语）
* other than表示“只好,远不如,不同于…”.如：
I can't do other than to go.我只好去.（不定式）
She performed other than perfectly.她表演得远说不上完美.（副词）
They were given nothing other than dry bread and water for their evening meal.他们晚餐仅仅分到干面包和水.（名词）
* more than 表示“多于,胜过,不仅仅”,than是介词,后面跟名词作宾语.如：
He disliked no one more than her.没人比她更惹他讨厌.
He is more than a scholar.他不只是个学者
* else than意思是“除...别的以外”,常跟在-thing,-body,-one一类的合成不定代词后,后面跟不带 to 的不定式,如：
*He did nothing else than laugh.他除了笑以外没做其他事.(他只是笑.)
* anywhere than 意思是“除...地方以外”,后面跟名词或不带 to 的不定式.如：
You can visit else anywhere than stay at home.你可以参观任何地方,只是不要呆在家里.
4.以下是一组由 soon 的比较结构构成的短语,
would sooner（=would rather）宁愿
would just sooner 仅只宁愿
would sooner…than…宁愿…也不
had sooner…than…刚一…就
would as soon as…总会一…就
二、请把下面两个句子改成陈述句,并分析句子成分.
What does he like to do besides read novels?
改为陈述句：He likes to do other things besides read novels.除了看小说外,他还喜欢做些别的事.
结构分析：
1、What does he like to do besides read novels
主语：He
谓语动词：does like
宾语：to do / what （what 都是不定式的宾语）
方面状语：besides read novels
2、What does he like besides to read novels?
主语：He
谓语动词：does like
宾语：what
方面状语：besides to read novels
三、下面这个句子正确吗?请写出句子成分分析.
There was nothing else but to leave.除了离开别无他法.这个句子不对,应该改为——
1、There was nothing else to but leave.
2、He did nothing else than leave ——他除了里开外什么也没有做（或者：他只能离开）
四、下面两个句子正确吗?有什么区别?
都正确,前一句中含有动词 do,要求用不带 to 的不定式；后一句中没有动词 do,要求用带 to 的不定式.
1.The enemy can do nothing but surrender.敌人除了投降之外,别无出路.
2.The enemy had nothing to choose but to surrender.敌人除了投降之外,别无选择.
附言：你的问题不仅多,而且也大,有的还重复,做起来很费事,一言半语解释不清楚,只能删繁就简回答了以上的问题.
