公共英语三级属于英语的中间级，需要经过笔试和口试。对于2017年下半年的公共英语三级，小编为大家准备了干货分享，帮助各位考生攻克公共英语三级。
一、观点态度题型
对话中对话者对他们谈论的人或事持什么观点或态度往往含而不露，考生只能根据对话内容的关键词、上下文甚至语气、语调的内涵意义并利用逻辑思维能力来进行判断，才能对传递的信息进行比较深层次的理解。具体表达观点、态度时，可能出现的模式有：间接表达式，不明说赞成或反对;反问否定式，常委婉地表示质疑和反对;委婉谢绝式，先表示肯定、赞成、谢意等，随后说出真实看法;看似否定实为肯定式，如 why not, I can’t agree any more 等。
常见的提问方式有：
How does the man/woman feel about...?
What does the man/woman think of...?
What does the man/woman say about...?
What does the man/woman mean?
二、地点方向题型
这种类型的考题主要考查学生对对话地点及人物去向的判断。其中既有直接提问的，也有间接提问的。
常见的提问形式有：
Where does the conversation probably take place?
Where is the woman going?
Where are the two speakers?
在这类考题中，选项大部分是表示地点场所的名词，同时需注意这些名词前的介词，如in a bank, in a dining-room, at the airport, at home, on the desk, on the floor等，这些介词对判断场所非常有帮助。另外，考生应集中注意力去捕捉那些“关键词”，抓住了“关键词”，做题就容易多了。以下是一些常考的地点及相关词，也就是刚才提及的“关键词”，需重点记忆：
学校(school)：required course, elective course, quiz, professor, thesis, make-up, credits, master, dormitory, department, lecture, essay, bookshelf, application form, entrance.
旅馆(hotel)：reception, book, reservation, tip, check in, single room, double room.

二、感官动词、使役动词的用法及英语中常考的两个句式结构
1、感官动词的用法及其被动语态：在英语中，常见的感官动词有“五看二听一感觉”(see、watch、look、notice、observe;hear、listen to、feel)，在主动语态中用动词原形或现在分词作宾补，如see sb do/doing sth，改为被动语态时则要加to，如sb be seen to do sth.
2、使役动词的用法及其被动语态：在英语中，常见的使役动词有make、let、have，在主动语态中用动词原形做宾补，如make sb do sth，改为被动语态时则要加to，如sb be made to do sth， 两种形式都表示使/让某人做某事的意思。例：We were made to study hardy.我们被要求努力学习。
3、英语中常考的.句式结构一：sth need/ want/ require doing 某物需要?(=sth need/want/require to be done)(此句式主语为物)例：My room is a mess. It needs tidying up(整理)。
4、英语中常考的句式结构二：have/get sth done 请/让别人做某事(have/get后接宾语为物)

三、情态动词
常见的情态动词有can、could;may、might;must、need;should;ought to，对于情态动词常考其两方面的内容，一是情态动词用于推测句型，二是情态动词用于虚拟语气(该部分的讲解放在虚拟语气)
1、情态动词用于对现在内容推测的常见句型有：
Can/may do sth：表示对现在内容的可能性的推测;
Must do sth：表示对现在内容的肯定性的推测。
2、情态动词用于对过去内容推荐的常见句型：
