详细地帮我讲解下吧..光给我答案没用呃...
2的答案给的是b啊，还有1 解释一下呃..
第一题 B第二题 A解释：________is now part of the United States部分为 in 的宾语从句，这里表示地点所以用where，不用what。（若选C，则定语从句中缺少主语。若选D，则定语从句中缺少先行词。）第三题 B解释：Because是连词，后面应该跟一个完整的句子，而all the representatives still not there 缺少谓语第四题 are 解释：当or,either...or,neither...nor,not only...but also等连接两个并列主语时，谓语动词遵循就近原则 第五题 helping 解释：to do 不定式表目的时一般不用...
