desire 名词,“要求,心愿”,后面的 that 从句是主语从句,从句中要用虚拟语气,用情态动词 “should + 动词原形”的结构,而且 should 可以省略.所以选 C.(should) be made.
全句中文意思：“我们的要求（或心愿）是要付出一切努力来保护学校里面的环境.”

你好。句型是：
it is our desire that +句子（谓语动词是should+do / be done）-----should可以省略。
又如：
It is Tom's desire that he (should) get married with Mary, his next-door neighbour.

应该添should be made, 但这里should被省略了. 网上有解释, 如下:
一般说来，在一些特定的词语引导的从句中都要用带should的虚拟语气。在美国英语里，should是可省掉的。具体的省略情况如何呢？现归纳如下：

应该添should be made, 但这里should被省略了. 网上有解释, 如下:
一般说来，在一些特定的词语引导的从句中都要用带should的虚拟语气。在美国英语里，should是可省掉的。具体的省略情况如何呢？现归纳如下：
1．凡是由suggest，request，order，demand，propose，desire，command，insist等及物动词所带的宾语从句，其谓语部分的should可以省。例如：
The old peasant suggested that a reservoir（should）be built at the foot of thehill，那位老农建议在这座山脚下修座水库。
“The experiment had failed！”“I suggest you（should）try again．”“实验失败了！”“我提议再试一试。”
I desire that you（should）finish the task today．我希望你今天完成这项任务。
They requested（demanded）that everyone（should）attend the meeting ontime．他们要求大家准时出席会议。
He proposed that we（should）visit their school next week．他提议我们下周参观他们的学校。
The captain ordered（commanded）that his soldiers（should）go on to thefront．上尉命令他的战士继续开往前线。
The boy insisted that he（should）go back alone．这孩子坚持要一个人回去。
2．凡是由“It is（was）requested（ordered，suggested，desired，decided等）that…”引导的名词性主语从句中，其谓语部分的should可以省略。例如：
It is requested that the cloth（should ）be woven at once．下令马上织这种布。
It is desired that the bridge（should）be built in two years．要求两年内建成这座桥。
It has been decided that the meeting（should）be held tomorrow已经决定会议明天举行。
3．凡是由“It is（was）important（necessary）that…”引导的名词性主语从句中，其谓语部分的should可以省略。例如：
It is very important that everyone（should）work well．大家把工作做好是很重要的。
It is necessary that our college students（should）master a foreign language．我们大学生掌握一门外语是很必要的。
4．凡是主句中有以suggest，proposal，order，idea，plan，news，motion，demand等名词后面所带的表语从句或同位语从句中，其谓语部分的should可以省略。例如：
Xiao Wang's suggestion is that we（should）play basketball after school．小王建议放学后打篮球。
My idea is that our class meeting（should）be held next week．我的意见是下周开班会。
I agree to your motion that we（should）go swimming this afternoon．我赞成你的建议，今天下午我们去游泳。
They are discussing your proposal that we（should）visit the Great Wall of China tomorrow．你建议我们明天去参观长城，他们正讨论。
5．凡是由lest（以免；免得），in case（以防）和 for fear that（生怕，唯恐）引导的目的状语从句中，其谓语部分should可以省略。例如：
Keep quiet in case you（should）interrupt him when he is busy．要保持安静， 以防打扰他。
She is now studying for fear that she（should）fail in English．她现在很勤奋，生怕英语不及格。
You must wake him early lest he（should）be late for school．你务必早点叫 醒他，以免他上学迟到。
值得一提的是，在以上五种情况下用虚拟语气是美国英语和英国英语共同的特色，所不同的是美国英语通常省掉should，而英国英语通常保留should。
