一、（）favourable conditions, He should have performed well.
A.With B.But for C.Under D.Due to
本题考察虚拟语气，尤其是考察under引导的状语成分的虚拟语气。under favourable condotions 是指“要是在有利的条件下...”due to 不能导致虚拟语气的产生。B也可以导致虚拟语气 但是句意不通顺，故选C。
二、save 的熟词僻义＋except与except for 的区别。
save 本身也可表除...之外
eg. She gave me that pen save this one.
还可以save that也表除...之外
eg. We knew little about him save that he had a brother.
except一般是同类中的一个是例外，except for是指大范围中的小类事物为例外，不是同类哦
eg. everybody was invited except me.
except for an old lady, the bus was empty.
三、sb had hoped that...通常表示过去未实现的愿望，比如，He had hoped that he could have been a doctor.他本可以成为一名医生。那么，有三个可以表示had hoped相同意思的词组你知道是什么嘛？

2.sb meant/planned to have done sth
3.sb was/were to have done sth.
She was to have bought apples她本打算去买苹果的。
四、恶性循环与良性循环
恶性肿瘤与良性肿瘤。
恶性循环：vicious circle/cycle
良性循环：virtuous circle/cycle
恶性肿瘤： benign tumor

take sth on
