1,over ,是在...上面,
Eg: The bridge is over the river.桥在河的上面.
cross和across,都是穿过的意思,只是它们的词性不同,cross是动词,across是介词,
Eg:He crossed the street .
He went across the street.(他穿过街道.)
through 也是穿过的意思,它是指从物体的内部过,
比如,穿过隧道, go throgh the tunel(隧道)
穿过森林, go throgh the forest

2,D. look like和be like都是"看起来象..."本句中,主语the boy是第三人称单数,所以,动词应用相应的第三人称单数形式,故,只能选D,is like.
