一般现在时的用法

He was named after his father.——这句话只说明他在起名的时候跟他父亲一样。只表示一个过去的动作或状态(named 可以看作形容词表状态),网友可能想知道,此人是否健在。最大的可能是,此人已不健在。The street is named after the famous South African leader, Nelson Mandela. ——一般现在时,不仅表明过去被命名这个...

倒装句(涉及Lying here is a girl类型的句式)

(1)除了写成Lying here (there) is a girl.还可以写成Here (There) is lying a girl.吗?如果可以,这两个句子有什么区别,同理Lying on the couch is a girl.和On the couch is lying a girl.有什么区别?【答】Lying here (there) is a girl. ——这个倒装句正确。但不可以写成Here (There) is lying a girl. 因为,here (t...

have it good是什么用法

You already have it good. have 偶尔可以接形容词作宾补。如: I expect Amy will have the tea ready right now. The long trip had them extremely tired. 但我的语感是,这句中的 good 是副词,应该理解为状语。

动词mark的含义理解?

But there's one obstacle that's marked ice cream makers since the industry's earliest days. 网友没看见 marked 后面的宾语吗?提问题之前先好好想想。mark 在这里可以理解为“妨碍,困扰”,ice cream makers 为宾语。

不定式和现在分词作后置定语的区别

it isn't the only company to have tried ice cream on demand.现在分词完成体,不能作定语。不定式可以,或者改用定语从句。it isn't the only company having tried ice cream on demand. (误)it isn't the only company that (has) tried ice cream on demand.

麻烦老师分析一下 less than 和 as many 比较句型如何理解?

1. Some companies like Pet Health Inc. which track national demand for dogs and cats, say adoptions in 2020 are actually less than they were in 2019.——现在人们喜欢用 less than 代替 fewer than,可能是发音不便的缘故。主语是复数可数名词,本应跟 fewer 搭配。2. That not as many people have gotten a new p...
