英语一句话中怎样判断是系动词？常见的系动词有哪些？

Question

？？？？？？？？？？？？？？

Answer 1

用BE动词去替换该动词,若意思能说通,就说明该词为BE动词。She looks beautiful.可以说成She is beautiful.此时，look为系动词。
但She eats an apple. 不能说成 She is an apple. 故eat不是系动词。系动词很多。具体要看在句中所作的成分。常见的系动词有：look , seem , stay, go, become, turn, get , sound, smell,taste

Answer 2

系动词很多。具体要看在句中所作的成分。常见的系动词有：look , seem , stay, go, become, turn, get , sound, smell,taste, and so on. 其中sound, smell,taste等要看是不是实意动词啊。
She is feeling the soft Chinese silk carefully. (此时的feel 不是系动词了。)
