There are four groups of sentences. I tried to make sentence B express the same meaning as sentence A's but in a different way. Please correct them for me. Thanks a lot.( ^_^ )

1)A. Little donkeys thread among the throngs of people.

   B. Through the bunch of people move slowly some small donkeys.

2)A. They narrow down their choice and begin the really serious business of beating the price down.

   B. They reduce the number of their choices and start to haggle seriously over the price.

3)A. He will price the item high and yield little in the bargaining.

   B. In the bargaining, he will not compromise much over the high price of goods.

4)A. As you approach it, a tinkling, banging and clashing impinges on your ear.

   B. You can hear something tinkling, banging and clashing as you come close to it.

          Thanks for your check. If you know how to express those better, PLEASE let me know.\(^o^)/
