32、He (help) us in the Anti-Japanese War. He (always, remember)by us Chinese people. 解析 答案：1 was awarded 本题时间状语是last year，可知句子应用过去时态，且只说明一个事实，因此用一般过去时态。由于主语Tom 是被授奖的对象，所以用被动语态。2 had worked 因为有since 1998，宾语从句应用现在完成时态，但宾语从句在此是作主句谓语动词said的宾语，所以现在完成时得改为过去完成时。3 Have, heard, knows, helped, will always be rem

40、。2 sitted 改为sat sit 是不规则动词，它的过去式是sat。3 why改为because 这里引导的是原因状语从句，所以该用because。4 sleept改为slept sleep 是不规则动词，它的过去式为slept。5 at 改为in 因莫斯科是个大地方，该用in。6 were改为was 因主语time 是不可数名词，所以谓语动词该用单数形式。7 doesnt改为didnt 根据上下文理解，这里该用过去时态。8 on改为in on表示在物体的表面上。9 anywhere改为everywhere 此处指“到处”。10 inside改为outside或out 这里指恶劣的天气里
