本题考查八年级上册核心语法与固定搭配，逐空解析如下：
15. 句中描述过去发生的动作，后文introduced提示时态为一般过去时，arrive的过去式为arrived。
16. 此处泛指“一个非常可爱的女孩”，very以辅音音素开头，用不定冠词a。
17. 固定搭配ask sb. to do sth. 意为“邀请某人做某事”，故填to sit。
18. 前文提到Paul很想和Lisa交谈，后文说他几乎没法和她搭上话，前后为转折关系，句首首字母大写，填But。
19. 固定搭配be busy doing sth. 意为“忙于做某事”，动词talk变为动名词talking。
20. 空前有some修饰，plan是可数名词，需要变为复数形式plans。
21. 固定搭配make sb. do sth. 意为“让某人做某事”，后接动词原形，填feel。
22. 介词to后面要接人称代词的宾格形式，they的宾格是them。
23. 此处暗含和之前的喜爱程度作比较，much可修饰比较级，well的比较级是better。
24. 固定搭配feel sorry for... 意为“为……感到抱歉”，填介词for。
