Answer 1

1. C
be convinced of... 确信，认识到...
the effect on... 对...的影响/作用
2. C
逗号后面是非谓语动词做结果状语。
从句意来看，它表示由主句句意可以顺理成章推理而出的结果，所以用现在分词构成的短语。
如果是表示出乎意料的结果，则一般用不定式短语做结果状语。
再如：The earthquake happened at night, leading to many wounds and deaths.
3. A
解释同上题，即用现在分词构成的短语做结果状语，表示顺理成章的结果。
4. C
解释同上两题，用现在分词短语做结果状语，表示顺理成章的结果。
5. A
根据句子结构，可知____to be solved为后置定语，修饰problems.
而remain是系动词或不及物动词，不能用于被动结构，排除BC。
remain to be done是固定短语，意思是“有待于被...”，且problems和remain之间为主动关系，且remain该状态现在正在进行，所以选A remaining.

Answer 2

1.be convinced of sth.相信某事effect on sth.对某事的影响2.the news 为句子主语，shocked为谓语，leading为分词表结果，是主动。3.用2的方法理解一下句意。4.同25.rimaining为现在分词，表主动，修饰problems
