回答：一题选d：occur to sb.突然出现在某人脑海里
一个不错的想法突然出现在我的脑海里，我可以用零钱买条领带，作为生日礼物送给爸爸


二题选a：

it指前面提到的“同一”事物。My father bought me a pen and I like it very much.我父亲给我买了一支钢笔，我非常喜欢它。

that是指前面提到的“同类”事物。如：
This dictionary is more useful than that (=the one)I bought yesterday

those只能替代可数名词

one替代“a＋单数可数名词
此题属于第二种情况，所以选a
