1不是现在完成时.是一般过去时,由谓语动词 pretended 可知.
2 pretend主要用法有,pretend to do ,pretend + that从句
而pretend to do 有pretend to do sth（一般式）；prentend to be doing sth（进行式）；prentnd to have done sth（完成式）形式.
因为谓语pretended是过去,而read这个动作发生在 pretended之前,所以用完成式.
3这个句子并没有用过去完成时.
再问： to have read 不是完成时？
再答： to have read 是用了完成时，因为read这个动作发生在pretended之前. 但没有用过去完成时。
