pretend
1.下面三句意思相同：
He pretended to be ill.
He pretended that he was ill.
He pretended illness.
2.注意下面第一和第二句里有to，第三和第四句里没有to：
He pretended to great learning.
She did not pretend to much wisdom.
He pretended illness.
She pretended friendship for us.
pretend(ed) to是“自以为有…（也许真有，也许没有）”，那后面的名词总是指“学问”、“智慧”、“美德”等，pretend(ed)是“假装着…”。
