Lucy starts to do her homework at six o'clock.
start to do sth
The first lesson starts at7:15.
一般现在时,第三人称单数(the first lesson),后面动词变形.
He often uses the Internet to do their work.
use to do
not good at doing sth
Swimming is her favourite sport.
swimming这里做主语,是名词游泳,而非动词游泳.
一般现在时,主语是第三人称单数(he/she/it),动词要相应变形.
现在进行时、介词后面、部分动词后,它们后面所接的动词用ing形式.
一般现在时,主语是第一人称单复数、第二人称单复数、第三人称复数,一般用动词原形.
部分动词后再接动词,要用动词原形.
