I am surprised 后面接的为什么是宾语从句

I am surprised that you should think the exam is pretty diffcult.在 think 后面确实省略了一个 that,宾语从句省略 that 很常见,同时本句也是为了避免两个 that 重复:I am surprised that you should think (that)the exam is pretty diffcult.由此看出,the exam is pretty diffcult. 是 think 的宾语从句。由于网...

副词修饰名词和及物动词问题

1. There was always music on in my house when I was little.on 是副词作 music 的后置定语。相当于一个定语从句 which/that was on。此时,on 的含义是“(指活动)在进行中”。又如:Let's go to the cinema— there's a good film on this week. (on 是副词作定语,不是介词,this week 不需要介词,而且也不能用on )咱...

地点状语能作主语吗

Hominid footprints found in South Africa in the mid-1990s and fossil remains uncovered since 2002 in Central Africa and near the Black Sea suggest that hominids may have walked upright as early as six million years ago.两处黑体部分都是过去分词短语作定语。在 uncovered since 2002 in Central Africa and...

关于down的理解

1. She [looked down the road] to see if anyone was coming.这里有两种翻译方式:①她往下看这条路……(因为look down是一个词组,译为往下看)②她顺着这条路看……(因为down作介词,译为顺着)这两种翻译方式正确吗?——从结构看,looked down the road 中,down 是介词,不是副词,因为后面接了宾语 the road。用作介词时,down...

这句话这里为何使用which

sensor detect when the dumpster are full,at which point a text is automatically send to a local operator says that...◆网友应该把句子写完整,以便分析和理解句意。此外,里面有多出错误:1. sensor detect(单数可数名词缺少冠词,或用复数,detect 应该用单三形式);2. the dumpster are full,应为 the dumpste...

at the time , at that time的区别

1. at this time = at this moment 目前现在——这两个词组不完全相等。at this time 除了指瞬间,还可以指一个时间段,而at this moment 只能指瞬间,这是 moment 的词义决定的。如果没有this 和 at 这两个词,那么 time 和 moment 是不相等的。time 指一个无限的时间,而 moment 则是指“瞬间”。但是,如果 time 之前加了指...

不及物动词talk和speak为什么都后接了宾语

In the Grimm's stories, a forest is often the home of evil witches (as in "Hansel and Gretel"), talking animals, and magical beings.——talking animals, 这是一个含有现在分词的名词短语,不是动宾结构。talking 是不及物动词作定语,意思是“会说话的动物”。For centuries, storytellers - called rune singers-lea...

介词of使用迷惑

1)What example is given of a story that includes an evil witch ?2)What is an example of a moral that appears in Grimm's fairy tales ?of 本身可以表示 “关于;涉及”,与about 同义。以上两句用法相同,区别是:第一句的 example 与 of a story  被谓语动词 is given 分隔。

非谓语动词用法疑问

Parnia's team, in an ongoing experiment, set up special shelving in rooms in which people are resuscitated, holding randomly generated pictures on the ceiling at an angle that require an out of body experience - the person would have to be separate from the corporeal body to see the images.1. 这一部...

介词to后面为什么没有成分

Any problem that has something to do with teenagers' mental health is worth paying attention to.be worth  的用法要求:后面接的动名词,其逻辑宾语一定是句子的主语。因此,这个动名词必须是及物动词或者及物的短语动词,且一律使用主动形式。包括:1. 及物动词:The film is worth seeing.2. 不及物动词 + 介词:Th...
