题型：不详难度：来源：
Don’t lose heart; __________ difficulties you are faced with will be overcome in the end.| A．however | B．whatever | C．what | D．How |
|
答案
| B |
解析
试题分析：考查主语从句。本句中的whatever difficulties you are faced with是一个主语从句。要注意后面的是名词difficulties ,故使用whatever来引导。However后面要接形容词或者副词来引导。“No matter+特殊疑问句”只能引导让步状语从句；“特殊疑问句+ever”既可以引导让步状语从句，也可以引导名词性从句；句意：不要失去信心，你们面对的无论什么困难最后都将被克服。故B正确。
点评：本题考查了主语从句的连接词，如果后面是名词或者名词短语就使用whatever来引导。However后面要接形容词或者副词来引导。要特别注意“No matter+特殊疑问句”只能引导让步状语从句；“特殊疑问句+ever”既可以引导让步状语从句，也可以引导名词性从句； |
