五、语法知识
宾语从句综合 & 动名词作主语 & 宾语从句时态呼应
【一、宾语从句时态呼应规则（必考！）】
◆ 规则①：主句为现在时 → 从句可用任何时态（根据实际需要）
I think he is right.（现在）I think he was right.（过去）
I wonder if it will rain tomorrow.（将来）
◆ 规则②：主句为过去时 → 从句须"时态后退"
一般现在时 → 一般过去时：He said he was busy.
现在进行时 → 过去进行时：She said she was reading.
现在完成时 → 过去完成时：They said they had finished.
一般将来时 → 过去将来时：I thought it would rain.
◆ 规则③：客观真理永不变（不受主句时态影响）
He said the earth moves around the sun.（永远用moves）
【二、动名词（doing）作主语】
◆ 动词-ing形式可作主语，谓语动词用单数
Reading is a good habit.（阅读是一个好习惯）
Learning English well requires practice.（学好英语需要练习）
◆ 常用结构：It is + adj. + doing sth.
It is no use crying over spilt milk.（覆水难收）
It is worth reading this book.（这本书值得一读）
【三、whether...or not 的三种写法】
◆ ① whether or not 连在一起（最正式）
I don't know whether or not he will come.
◆ ② whether...or not 分开（or not放句末）
I don't know whether he will come or not.
◆ ③ if...or not（口语中可用，但正式考试建议用whether）
介词后、不定式前、主语从句中只能用whether
【四、be likely to do sth. 很可能做某事】
◆ 结构：sb./sth. + be likely to do
It is likely to rain tomorrow.（明天很可能下雨）
You are likely to succeed if you work hard.（如果你努力，很可能会成功）
◆ 反义：be unlikely to do 不太可能做某事
【五、keep...in mind = remember 牢记】
◆ keep the rules in mind 牢记规则
◆ keep my advice in mind 记住我的建议
◆ 类似短语：learn...by heart = memorize 背诵/记住
【六、run out 与 run out of 辨析】
◆ run out（不及物）→ 某物"被用完"，主语是物
Our money has run out.（我们的钱用完了）
◆ run out of（及物）→ "用完"某物，主语是人
We have run out of money.（我们用完了钱）
run → ran → run（过去式/过去分词不变）
