1.I was asked to make a speech .这句是过去时吗?为什么make不用made了?
2,disappointed和disappoinment的区别是什么?
3.remark和notice,observed的区别是什么?
4.in case的用法有那些了?
我知道了是被动语态咯- -

2.disappointed是disappoint的过去时和过去分词,同时也是一个形容词,表示希望退却后的难过心情,直译就是‘失望的’；而disappointment是名词（你原问题漏了t）,表示：失望的行为；失望的感受；还有就是失望的人.
他很失望(disappointed); 他是失意人（disappointment); 他现在知道什么是失望了disappointment).
3.remark可以名词,可以动词.作为名词可以说是一种描述noticing和observing的行为.也是一种注释或标记（简短的,随笔性质的）.作为动词,就是上述名词的动词化.
notice同样可名词,可动词.作为名词,就是记录、观察,理解和留意,程度上比remark的随意性要正规；也表示书面的声明、通知等.动词则是名词的动作化.
Observed是observe的过去时和过去分词,也是形容词,表示经科学观察发现或断定的.observe则是动词,表示经仔细、刻意发现而获知；这个观察发现是在不干预被观察对象的情况下进行的,因此有系统科学地观察的意思.需要注意的是,observe和notice和remark都有点关系,更趋向与notice,但是以那种仔细全面的方式；而只在表示说的时候,才和remark类似,是say casually的那种.
4.In case 就是"以备万一"的意思,即是一种假设,也是一种小心.
再问：你可以举些句子例子吗？第三个问题
再答： remark 名词： the event passed without remark，事情顺利通过了，没有留下任何首尾。动词： place worth to remark，只得一提的地方 notice 名词：That detail escaped my notice. 细节超乎我的观察。动词：noticed a figure in the doorway. 留意到门庭里有个人。 observe 动词：observe a child's behavior. 仔细观察孩子的行为。 observed no explanation for the observed phenomena. 对观察到的现象无法作出解释。
再问：好的，谢谢了
再答：不客气， you are welcome, :-)
