题目分析：
小题1:He has made great progress in English this semester.
本题的关键在于名词progress是一个不可数名词，没有复数形式，和动词make连用，形成make progress的固定搭配。
小题2:Only by washing hands often / frequently / regularly can we avoid being infected by disease(s).
Only when we wash our hands often / frequently / regularly can we avoid being infected by disease(s).
本题考察的是only引起的倒装句，当Only放在句首，且强调状语的时候，后面的主句使用部分倒装的形式。
小题3:The principal / headmaster made / delivered a speech / an address at the graduation ceremony, which was deeply impressed on our minds / memory.
本句考察的是动词impress的用法，impress sb 给某人留下深刻的影响。以及which引导的非限制性定语从句的具体用法。
小题4:The problem, if (it is) not dealt with properly / well, will get worse and worse with the passing of time / as times goes on / with time going on.
本句考察的是状语从句的省略。当状语从句的主语与主句的主语一致，且状语从句中有系动词be的时候，可以把状语从句的主语和be动词一起省略。如果状语从句中有it is的时候，it is 也可以省略。
小题5:Though he is fully / well aware that smoking is harmful to / does harm to health, he is always turning a deaf ear to our advice that he (should) give up / stop / quit smoking.
本句考察的是though引导的让步状语从句，以及do harm to对…有害的；和形容词aware的用法，该词后面可以直接加从句，或者形成be aware of的结构。
点评：做这类题，不但要选择正确意义的词、词组及句型，还要根据具体语法和语境，选择适当的时态、语态及使用正确的词形。
