答案

这个题目出错了.mustn't只表示“禁止”、“不允许”,语气强烈.Youmustn't do well in the exam意思是“你不准在考试中表现良好”,这怎么可能呢?
应改成：
Study hard,or you won't do well in the exam.
=Study hard,and you will do well in the exam.
这两个句子的共同点是：前一分句是祈使句,后一分句是表示结果的分句.这种结构的两个子分句中间一定要用一个并列连词.
Last Saturday I walked in the zoo with my uncle.l w--------many animals.They come from many countries in the west.My uncle k------many animals in the zoo.Everyday he feed animals food.Now let me introduce some animals to you.Koalas come from Australia.They' re w------to watch.Dolphins are very lovely and clever.They live in the water.They can dance well with m------.They m-----people excited.
