分析下面三句话的主谓宾等
（2）you would consider octopus a great delicacy.You would not be able to understand why some people find it repulsive.
（3）No creature has received（ more praise and abuse than the common garden snail）.
（4）I happened to be walking in my garden when I noticed a huge number of snails （taking a stroll on some of my prize plants）.

答案

1 包含两个从句,When 后面引导的时间状语从句,其中又套两个what 引导的宾语从句.
2 第一个句子主语 you 谓语 would consider 宾语octopus 宾补a great delicacy
后一句 主语 you 谓语would not understand 宾语由 why some people find it repulsive从句充当.
3 主语creature 谓语has received 宾语more praise and abuse 比较状语从句than the common garden snail
4主语I 谓语happened to be walking 地点状语in my garden 时间状语从句 when I noticed a huge number of snails （taking a stroll on some of my prize plants） ,其中括号部分是现在分词结构作定语,修饰snails,
