有3道英語選擇題.
1.If you plant watermelon seeds in the spring ,you( )fresh watermelon in the fall.
A.eat B.would eat C.have eaten D.will be eating
為什么不能選B啊?是不是后面不能用would那種的?
2.For many years,people( )electric cars .However,making them has been more difficult than predicted.
A.had dreamed of B.have dreamed of
C.dreamed of D.dream of
這題為什么不選C啊?為什么一定要在前面加一個have?
3.The traffic rule says young children under the age of four and ( )less than 40pounds must be in a child safety seat.
A.being weighed B.to weigh C.weighed D.weighing
不是說weigh無進行無被動嗎?為什么選D呢?
因為老師講過一遍我還是沒懂又做錯了.
第1句不就是虛擬的嗎?不是有個IF嗎?
第3句沒看懂.
