1.see sb.doing sth.看见某人正在做某事 这里是指他常常被看见和农民们一起劳动.现在分词表示动作正在进行,表主动.
2.used to 过去常常,选D 与前面There 构成There used to be 表示过去曾有,表存在的有,而have 表所属的有,故不选D,
3.现在分词做原因状语,若去掉横线的逗号可以选A做目的状语.
4.swim 其后的介词不能省 ,to swim in 的宾语是前面的water,像这样宾语可以在前面找到,或者逻辑宾语是句子主语的,就叫做反射不定式,因为宾语存在,就要用介词.
例如：
I feel that zoos provide clean and safe places for endangered animals to live.
LIVE的主语是ANIMALS,也就是只有主语,没有宾语,所以不用加介词了.
动词之后加介词一般都是因为动词不及物,所以加上介词加宾语；如果不及物动词之后没有逻辑宾语,就不用加介词.
再举例：The chair is very comfortable to sit in.（这个椅子坐上去非常舒服）这个句子,也可以说成,To sit in the chair is very comfortable.或者：It is very comfortable to sit in the chair.因为 in的宾语是chair所以要用介词.假如是It is very comfortable to sit.（坐着非常舒服）这里就不用介词了.
因此4不能选A.
祝进步.

下面回答的很好了，我就不赘述了。但是要说明下第四题填in的原因是swim in the sea。还有很多这样的例子，如 Can you give me a pen to write with?

1.see sb. doing sth. 看见某人正在做某事 这里是指他常常被看见和农民们一起劳作。现在进行时表示经常性动作
2.used to be 过去常常，过去有 固定搭配
3.分词做伴随状语
4.swim是不及物动词 其后的介词不能省

1.see sb doing sth, 而且这句是被动语态。
2。there be 表示有，have表示有，他们不能同时用，有区别的。
3.现在分词短语做主句的伴随状语
4.swim in the water.这是强调句，强调水冷.，所以把它们几个单词提前。

1、working 是一个伴随状语，在句子中与主语是主动关系
2、这是一个there be 句型和used to do 的结合体，构成了，“过去有…”句式
3、preparing 表原因，与主语是主动关系
4、先是too…to 句型， swim 为不及物动词，接宾语时必须跟介词
