這幾個(gè)題目我都選對(duì)了,幾乎都是語感,對(duì)時(shí)態(tài)的概念不是很清楚所以經(jīng)常會(huì)做錯(cuò).比如第一題,為什么要選完成時(shí).
如果有時(shí)間,可不可以幫我詳細(xì)的講講這幾道時(shí)態(tài)題目,不要只說對(duì)的選項(xiàng),解釋一下其他的選項(xiàng)為什么不對(duì),至少讓我明白點(diǎn)什么（我對(duì)這東西十分頭痛）
不勝感謝.
先謝謝回答
三樓的那個(gè)第一題，“有沒有東西落下”是在我“離開飯店前做的”我現(xiàn)在不是還沒離開飯店嘛，為什么要說是過去的過去呢？這里是不是強(qiáng)調(diào)一個(gè)結(jié)果什么的
那個(gè)第四題，我剛剛怎么樣，為什么要用進(jìn)行事態(tài)呢？反正都已經(jīng)是過去的事情了。
那個(gè)第三題不能就因?yàn)橐粋€(gè)was就確定是她正在說啊。其他的怎么不行了。
