Such a simple request. 
 
本句为 It was such a simple request 的省略.
 
But what ran through my mind was that if I touched him, I could lose my job. 
 
◎ 本句为多重复合句
 
第一重（全句）
    【主语从句】what ran through my mind
    【表语从句】that if I touched him, I could lose my job
第二重（包含在表语从句中）
    【主句】I could lose my job
    【条件状语从句】if I touched him
 
◎ 引导名词性从的关联词what 称作关系代词性连接词,等于“先行名词 + 关系代词”,相当于汉语的“所...的事物”.what ran through my mind  也可以改写为 the thing that ran through my mind.
 
So I told Billy I could not do that right now, but I suggested that he and I color a picture. 
 
◎本句为并列复合句
 
第一分句：I told Billy I could not do that right now,
 
    【主句】I told Billy （Billy是间接宾语）
    【宾语从句】I could not do that right now （直接宾语）,
 
第二分句：I suggested that he and I color a picture
 
    【主句】I suggested 
    【宾语从句】that he and I color a picture
 
◎动词suggest后面的宾语从句表示说话人的个人态度,要用虚拟语气,这类从句的谓语动词要用“should + 动词原形”或者“直接用动词原形”.凡是陈述个人意见的从句们都要用虚拟语气,类似的动词还有order,command,advise,insist,suppose 等.
 
Upon completing a wonderful piece of art that we were both very proud of, Billy again asked me to hold him. 
 
◎这是一个复杂句
 
时间状语Upon completing a wonderful piece of art that we were both very proud of, 
 
    【介词 + 动名词】Upon completing a wonderful piece of art   
    【定语从句】that we were both very proud of,
 
主句：Billy again asked me to hold him.
 
◎介词upon/on 后面跟表示瞬间行为的动名词意思是“在某瞬间行为之后就立即”,另如：
 
On entering the room, …  刚.一进这个房间便…
Upon hearing the news, … 一听到这个消息就…
On arriving home, …  刚到家就…
