doubt 与 suspect 的用法比较
doubt 与 suspect 作动词用 ， 都有“怀疑”的意思，但实际上它们的用法还是有区别的。下面我们就来比较一下：
一 . 如果后面接名词、代词或名词性词组时，两者基本上可通用。例如：
I doubt/suspect the truth of her statement. 我对她那番话的真实性表示怀疑。
He says he can cure me， but I still doubt/suspect him. 他说他能治好我的病，但我仍对他不放心。
二 . 如果后面接 that 从句，意思就截然不同。 doubt 意为“无把握；不相信（ question the truth of； don't believe/think ）”，怀疑其无。 suspect 意为“有存在或属实的想法；相信（ have an idea of the existence； believe； guess ）”，怀疑其有。例如：
I doubt that he has stolen my watch. 我不相信他偷了我的手表。魅力四川
I suspect that he has stolen my watch. 我怀疑 / 猜想他偷了我的手表。
The doctor suspected that he was ill with flu. 医生怀疑 / 认为他得了流感。
这时 doubt 更多用于否定句或疑问句中。如：
I don't doubt that he is right. 我确信他是对的。
I didn't doubt that he would come. 我当时相信他会来的。
Why did she doubt that they were cheats？ 她为什么怀疑他们是骗子？
自由自在的意思三 . doubt 用于肯定句中时，多接 whether/if 引导的从句，意义与 that 从句不同，这时意为“不敢肯定（ feel uncertain about ）”。而 suspect 不可接这种从句。例如：
I doubt whether/if he'll come. 我不敢肯定他来不来。
It's raining hard. I doubt whether it will be fine tomorrow. 雨下得很大，我不敢说明天会晴。
四 . 其他搭配。
doubt 可作不及物动词，用于 doubt of sth； suspect 用于 suspect sth to be， suspect sb of（doing） sth . be suspicious of sth. = be doubtful of 例如：
She never doubted of his success. 她从不怀疑他的成功。

由动词involve演化而来的形容词involved，放在名词前和名词后有不同的含义。放在名词后使用，大多是这个词的本意“牵扯进来的、有关的、卷入的”；放在名词前使用，意思大多是“复杂的、不易懂的、难于解开的” 例句：

牵扯到的公司中有一家是国企。（involved另一个含义的用法）
Concerned, concerning, regarding, regards
Richard was called in by the police to answer questions ______ disappearance of Thomas Ripley, who relatives were so _____ his prent situation.
A concerning; concerning about B concerned; worrying about
C with regards to; concerned about D regarding; concerned about
这个应该选 D。警方把理查德召来，询问了一些关于托马斯失踪案的问题。托马斯的亲属们很担心托马斯目前的处境。
concerning， regarding 是同义词，都是“关于”的意思。
concerned它的意思是“关注，担心”。
regarding, with regard to, as regards, in regard to 全都是表示“关于”， with regard to里面的 “regard” 没有 s。
As regards the people below them they are tigers.对于下面的百姓，他们是老虎。
With regard to houwork, my mother always argues with my father.
青年教师工作总结With regard to the money, we'd better be careful.
a country's laws in regard to human rights. 一个国家关于人权的法律
里面这个 regarding，你也可以换成 as regards 或是 with regard to。但是记住 with regard to 的 "regard" 不带 s
arrange 在用法上应注意以下几点：
1. 用作及物动词表示“安排”“准备”时，其后通常接事情，而不接具体的人或东西；若接具体的人或东西则需后接介词for，如以下两例中的for不宜省去：
We’ll arrange for an experienced teacher. 我们将安排一位有经验的教师。
更年期饮食I’ve arranged for a taxi. 我已安排好了一辆计程车。
2. 后接事情作宾语时，其后接不接介词for均可(在现代英语中以不接为多见)：
Would you like to arrange (for) a personal interview? 你希望安排一次个别接见吗?
3. 正因为表示“安排”时不能直接跟某人作宾语，所以要表示汉语的“安排某人做某事”，英语习惯上不说 arrange sb to do sth，而说arrange for sb to do sth：
I’ve arranged for Mary to meet you at the airport. 我已经安排玛丽去机场接你。
类似地，英语不说 hope sb to do sth，而说 hope for sb to do sth，不说 wait sb to do sth，而说 wait for sb do sth，不说long sb to do sth，而说long for sb to do sth等。另外还有，英语习惯上不说 demand sb to do sth，而说 demand of sb to do sth。
4. 其后可接that引导的宾语从句，从句谓语通常用虚拟语气，但有时也可用将来时态：
They arranged that the meeting (should) be put off to Saturday. 他们安排把会议推迟到星期六。
I’ve arranged that one of our reprentatives will meet you at the airport. 我已安排好派一个代表到机场接你。 车库的英文
比较同义句：I’ve arranged for him to attend the meeting.=I’ve arranged that he (should) attend the meeting. 我已安排他去参加会议。
5. 其后习惯上不接双宾语，如“请给我们安排一次与工人的会见”不能译为：Plea arrange us an interview with the workers. 可改为：Plea arrange an interview with the workers for us.
