1.He _______ _______ _______ (写下了)many of the things he has learned from them in scientific papers. 2.He doesn't have anybody to practice speaking English _________ at home 3.------How ________ is road near your shool? ---------It's 30 meters wide
1.has written down 2.with 3.wide 1.因为后面说he has learned这里也是现在完成时,所以前后时态应该一致. 2.他家没有任何人能和他一起练习英语.因为缺少介词with,所以这里要填上.是和的意思. 3.回答是30米宽,那么问题就一定是问你有多宽了.所以可以直接用回答里的wide.否则答非所问.
