1. C。
本题考查数量词的表达法，由句意可知，需要油做菜，所以选C，指“五公斤食用油”。
2. B。
本题考查分数的表达法，分子用基数词，分母用序数词，分子大于一时，分母要加-s。
所以四分之三是“three fourths”，地球表面是不可数名词，所以谓语用单数is。
3. B。
本题考查基数词和序数词的用法，第一空指第十五个纪念仪式，用序数词fifteenth，第二空指七年后，用基数词seven，注意in后接一段时间的句子，常用将来时。
4. C。
本题考查基数词用来表示年级、班级、房间号码、电话号码和编号。

名词在前，数词在后。
5. D。
本题考查基数词的单位hundred，thousand，million和billion等，当用来表示具体数目，前面有具体的基数词时，这些词的后面不加-s。
但是当hundred，thousand，million和billion等用来表示不具体的数目时用“hundreds/ thousands/millions/ billions of ＋名词”来表示，这些词的前面也不用具体的基数词。
本题属于后者。

基数词后面的hundred不加-s，三分之二的正确表达是Two thirds。
