连接副词However作句子什么成分

黎老师,您这本《英汉多功能词典》新编升级版,不该出现这么明显的失误。网友的题目也写的很清楚,however 是连接性副词。怎么能充当 conj. 引导从句呢?从属连词和连接性副词是两个不同的概念,前者是引出从句的,后者是副词作状语,是一种起连接作用的 “标识语”。用现在新的术语,however 叫做 “标记语”,也称为“连接副词...

touch down的用法

The plane touched down.touch down (着陆),等于 land(着陆),不说 land down。该词组借用 touch the land “接触地面”之意,touch + down (与 up 在相对)。

这里的及物动词后少了一个it

But Demis Hassabis, DeepMind’s boss, who founded in 2010 what was then an independent firm, did so hoping that they could also be employed to accelerate the progress of science.网友理解失误。found 是及物动词,肯定有宾语,但不是 it,而是 what was then an independent firm。你随便加一个 it 是什么意思?...

句子翻译

具体到一些词语,这句话可以有多种翻译。不过网友的这个翻译,总体上是很不错的。sea rice is a pioneer,这是比喻中的“暗喻”。汉语是允许的,英语中也大量存在。网友问的 “本是寸草不的盐碱地、沙漠” 是作什么成分”,你已经翻译出来了,是介词词组作地点状语,里面包含了一个定语从句而已。In saline areas and deserts wh...

I mean not wait till wednesday or anything. not解析

典型的口语特征,应该在mean 之后加一逗号,停顿一下。然后用 not 或 don't 否定动词 wait 均可,不能按语法规则去衡量句子的对错了:I mean,not wait till Wednesday or anything. I mean,don't wait till Wednesday or anything.

at ten years old和grow to over 80 meters tall

三个句子中,是不是介词,看括号说明。1. They could grow to six meters tall...    (to 是介词)2. 查《麦克米伦》grow词条:The redwood tree can grow over 80 metres tall. (over 是副词,修饰数字80,不是介词。该句没有介词)3. 网页上: They reached around eight meters in length at about 30 years old. (ab...

动词短语表语疑问

The world is a fine place and worth fighting for.网友不是叙述错误,就是理解错误。the world 是 fighting for 的逻辑宾语,不是逻辑主语。所以才不能加宾语。She is afraid of sth —— something 是必须有的,没有宾语的介词,就不是介词。
