5. that / which 1) 在名词性从句中
that在所有的名词性从句中都不作任何 成分,也不充当成分。

is already an open secret. which表示特定事物中的“哪一个(些)”,一 般情况下在从句中充当定语,后接名词, 在一定的语境中,它所修饰的名词可以省 略, 在名词性从句中做主语\宾语
4. who 与 whoever 在引导名词性从句时,在句中作主语
时用who,意思是"谁",含有疑问意 味,whoever是它的强语势"无论谁",不 含有疑问意味。表示…..的人,相当 于the person who,或anyone who
Eg: ___B__ breaks the law should be punished. A. Who B. Whoever
3. It looks like rain=It looks _a_s_if_/t_h_ou_g_h__ it is going to rain.
联想:
表语从句中的系动词只有be吗?还有其他的 动词吗? be, look, remain, seem, appear等
