The weather of yesterday was very cold,my father [這是不是有個(gè)and啊?]mother had took me back to grandma`s house.An hour later,here we were.哦對(duì)，忘打了，那and還變嗎？and是連接詞不變的。時(shí)態(tài)問(wèn)題除了時(shí)間名詞或者時(shí)間狀語(yǔ)以及動(dòng)詞變化往前推一個(gè)時(shí)態(tài)，其他都不變化。這個(gè)句子里，today就是時(shí)間狀語(yǔ)——今天。動(dòng)詞有is、are、took因?yàn)樽兂梢话氵^(guò)去時(shí)，所以都往過(guò)去推，is就是was，are是were，took本身就是過(guò)去，它繼續(xù)前推，是完成時(shí)，had took。兩個(gè)名詞間father是父親，mother是母親，他們應(yīng)該有一個(gè)連接詞，也就是連詞and。
