又是几道语法，请教！

以下是引用lf在2004-2-21 0:15:00的发言：
1，( Hair )     grows more     ( quickly )     in summer than in winter and more slowly at     ( the night ) than     ( during the day ).

ANS：C     请问应改成什么？====> night.     "at night" is a fixed phrase without "the".


2，,Many dinosaurs were ( so much     )     heavey that they     ( spent ) most of their lives is swamps and shallow lakes ( where ) water ( could support )     them.

ANS：A          可是为什么呢?
并问so much、very much、too much 在TOEFL 中如何区分？===> "so....that..." pattern.

3，,Transistors ( exhibit )     a high amplification factor,operate without ( distorted ) over a ( wide frequency )     range, and can be made     ( extremely small ).

ANS：B
是改成名词形式吧？===> yup.         "prep. + noun"

4，A     uniform minghlling of molecules,( which it )     occurs in homogeneous chemical compounds,results from     ( the chemical )     constituents melting,dissoving, (or )     diffusing into (     one another ).

ANS：A
是删调 it 吗？原因是定语从句，which代逗号前名短作从句的的主语。
是不是which/that 在定语从句中 有时作 有时不作 从句的句子成份，需视具体句意定？

prep. + which + subject + verb + object.


谢谢谢谢------------

at night是惯用法，中间不用加the

2，,Many dinosaurs were ( so much     )     heavey that they     ( spent ) most of their lives is swamps and shallow lakes ( where ) water ( could support )     them.

这里首先是结构so    。。that，已经有much的含义，加much多余。单纯的讨论so much、very much、too much 好像没有意义，只能说差不多，too much有的贬义

3，,Transistors ( exhibit )     a high amplification factor,operate without ( distorted ) over a ( wide frequency )     range, and can be made     ( extremely small ).

介词后面分词应该是改成ing形式

4，A     uniform minghlling of molecules,( which it )     occurs in homogeneous chemical compounds,results from     ( the chemical )     constituents melting,dissoving, (or )     diffusing into (     one another ).
