人教A版高中数学必修二有限样本空间与随机事件事件的关系和运算教学设计
新知讲授（一）——随机试验 我们把对随机现象的实现和对它的观察称为随机试验，简称试验，常用字母E表示。我们通常研究以下特点的随机试验：（1）试验可以在相同条件下重复进行；（2）试验的所有可能结果是明确可知的，并且不止一个；（3）每次试验总是恰好出现这些可能结果中的一个，但事先不确定出现哪个结果。新知讲授（二）——样本空间思考一：体育彩票摇奖时，将10个质地和大小完全相同、分别标号0，1，2，...，9的球放入摇奖器中，经过充分搅拌后摇出一个球，观察这个球的号码。这个随机试验共有多少个可能结果？如何表示这些结果？根据球的号码，共有10种可能结果。如果用m表示“摇出的球的号码为m”这一结果，那么所有可能结果可用集合表示{0，1，2，3，4，5，6，7，8，9}.我们把随机试验E的每个可能的基本结果称为样本点，全体样本点的集合称为试验E的样本空间。

常跟双宾语的动词有：（需借助to的）bring, ask, hand, offer, give, lend, send, show, teach, tell, write, pass, pay, promise, return等；基本句型 五S +V + O + OC（主＋谓＋宾＋宾补）特点：动词虽然是及物动词，但是只跟一个宾语还不能表达完整的意思，必须加上一个补充成分来补足宾语，才能使意思完整。 判断原则：能表达成—宾语 是…/做…注：此结构由“主语+及物的谓语动词+宾语+宾语补足语”构成。宾语与宾语补足语之间有逻辑上的主谓关系或主表关系，若无宾语补足语，则句意不够完整。可以用做宾补的有：名词，形容词，副词，介词短语，动词不定式，分词等。如：He considers himself an expert on the subject.他认为自己是这门学科的专家。We must keep our classroom clean.我们必须保持教室清洁。I had my bike stolen.我的自行车被偷了。We invited him to come to our school.我们邀请他来我们学校。I beg you to keep secret what we talked here.我求你对这里所谈的话保密。用it做形式宾语，而将真正的宾语放到宾语补足语的后面，以使句子结构平衡，是英语常用的句型结构方式。即：主语+谓语+it+宾补+真正宾语。如：We think it a good idea to go climb the mountain this Sunday.
