这篇句法找茬刚做过，是不是上传错了？
直接把上次的答案copy过来了 ：D

这篇做过了

3.of将前后名词连接成从属和所有格关系，那么前后的词性应该一样，所以应该是meanings.5,特殊疑问句在句中当宾语从句，该宾语从句不需要对调，即主语后接谓语。so the correct is"what a word means.".6.ask sb to do sth/sb=ask sb for n.寻求帮助。在原文中最后有宾语you，所以应该是to help。如果for不改成to，把you去掉也可以。8.应该是It's a dictionary.实意名词前要有限定冠词。9，some important things.根据some修饰可数名词复数来判断。

求助一：第2句什么意思，请试着从主语谓语宾语等分析句子成分？
意思: 你可能试着从你知道的词中去猜测这些词的意思.
句子成分:
you-主语.
might try-复合谓语.
to guess-不定式作try的宾语.
what the words mean -what引导词,整句作guess的宾语从句.
from the words-介词短语作状语.
you know-省略了which或that的限制性定语从句, 其先行词为words.

求助二：文中多处用到mean这个单词，mean有几种词性，各是什么意思？
1>mean 动词词性, 意思: 含有...的意思, 意指.
eg. 1.what does this word mean? 这个词是什么意思?
2. what do you mean by 'a lot of money'? 你所说的"很多钱"是指什么?

2>mean 形容词词性, 意思吝啬的,自私的, 卑鄙的.
eg. 1. It's no good asking him for any money - he's much too mean.
向他要钱是没有用的-他太吝啬了.
2. He is a mean man. 他是个自私的人.
3. a mean motive. 卑鄙的动机.

第二句的意思：你可能尝试从你知道的单词中猜测这些生词的意思.主语you,谓语might try to guess,宾语从句what the words mean,from the words you know.mean有三种词性：v.-意味着To respect the national flag means to respect the country.adj-吝啬的、苛刻的My husband is very mean.n.-意思 I know what you mean.

第2句的意思是“你会试图从你知道的单词来猜这些单词的意思”

3.the meaning of new words改成the meanings of new words；5.what does a word mean改成what a word means，这里做宾语从句要用陈述语序；6.ask him for help you改成ask him to help you，ask sb to do sth；8.It is dictionary.改成It is a dictionary；9.some important thing about words改成some important things about words。求助一：你可以从你知道的那些单词来才这些单词的意思，主语：You谓语：might try to guess宾语：what the words mean状语：from the words you know；求助二：mean第一个意思：苛刻的，don't be so mean to me，不要对我这么苛刻；第二个意思：意味着，it means you've get the championship这意味着你赢得了比赛；第三层意思：中间的，基本相当于average。 嘻嘻，做过的再做一次也不错啊！
