【分析】
【详解】
考查情态动词+have done。句意：——你昨天参加实验项目的会议了吗?——是的，但我想我（本来）不需要，因为我的主管在那里。Think/suppose等宾语从句中如果有否定词时，要把从句的否定词not前移，即“否定前移”。所以not是从句中的否定词。“need have done”意为“本来有必要做而未做”；“needn’t have done”指过去本来没必要做而做了。根据上一句时间状语“yesterday”可知本句指的是过去发生的事。结合第二句“because my director was there(我的主管)在”可推断出，我本来不必要去。故选D。

4、should作为情态动词,可以用来表示意外、惊喜或者在说话人看来是不可思议的.尤其在以why, who, how等开头的修辞疑问句或某些感叹句中常常译为“竟会”、“居然”。例如：How should I know it ?我怎么会知道这件事?
7、should作为情态动词,可以用于下列虚拟语气句中：
(1）用在表示与将来事实相反的条件状语从句中,构成“ If …… should（do sth）……, …… would/ could/ might（do sth.）…… ”句式。
5．—Daddy, would you please buy me an iPhoneX?
—If you can pass this midterm examination, you __________ have one as a reward.
A．mustB．need
C．wouldD．shall
2、should作为情态动词,可以用在条件状语从句中,表示语气较强的假设,译作“万一”、“竟然”,这时也可将should置于从句之首,即将should放在主语前面,而省略从属连词if。例如：If you should fail to come, ask Mrs Chen to work in your place.（= Should you fail to come, ask Mrs Chen to work in your place.）
（1）I shall think it over and Let you know my idea.我将考虑一下此事，然后告诉你我的想法。
（2）We shall have a good time in the park.我们在公园里会玩得很高兴的。
2. shall用于第一人称，表示征求对方的意愿。如：What shall we do this evening?
11．It wasn’t right to me that such near neighborsnot know one another.
A．couldB．would
C．shouldD．might
【答案】C
【解析】
【详解】
考查情态动词。句意：对我来说，很不正常，如此近的邻居居然不认识。A. could可能，能够；B. would将；C. should竟然；D. might可能，也许。should作为情态动词，可以用来表示意外、惊喜或者在说话人看来是不可思议的，常常译为"竟会"、"居然"，住的这么近的邻居居然不认识。表示意外，所以答案选C。

【答案】A

考查情态动词。句意：我喜欢周末，因为周六周日不必早起。A. mustn’t不能，禁止；B. needn’t不必；C. wouldn’t不会；D. shouldn’t不应该。此处表示“不必”，故B项正确。
考点：考查情态动词用法
点评：考本题是高考必考考点，一定要牢记句型意思。must have done过去肯定做了某事。should have done本应该做而实际未做。can’t have done过去不可能做了某事；shouldn’t have done本不应该做而实际做了。need have done本有必要做某事；needn’t have done本没有必要做某事；注意没有mustn’t have done的形式。
