(2)非限制性定语从句从句是对主句或先行词的补充和说明，去掉后不影响主句的意思，与主句之间往往用逗号隔开。The house, which we bought last month, is very nic

2、e. 当先行词是专有名词或被物主代词/指示代词所修饰时，其后的定语从句通常是非限制性的。Charles Smith, who was my former teacher, retired last year. My house, which I bought last year, has got a lovely garden. 非限制性定语从句还能将整个主句作为先行词，对其进行修饰，这时从句谓语动词要用第三人称单数。He seems not to have grasped what I meant, which greatly upsets me. 知识点2  关系代词与关系副词关

3、系代词who人主语Do you know the man who is talking with your mother?whom,which和that在从句中作宾语时,常可以省略,但介词提前时后面关系代词不能省略,也不可以用thatwhom人宾语Mr Smith is the person with whom I am working.The boy (whom) she loved died in the war.whose人、物定语I like those books whose topics are about history.The boy whose father works ab

2.学习、记忆是动物脑的高级功能。研究者通过电刺激实验,发现学习、记忆功能与高等动物的大脑海马区(H区)密切相关。如果在H区的传人纤维上施加100次/秒、持续1秒的强刺激(HES),在刺激后几小时之内,只要再施加单次强刺激,突触后膜的电位变化都会比未受过HES处理时高2~3倍,研究者认为是HFS使H区神经细胞产生了“记忆”。如图为这一现象的机制。A受体胞内肽段(T)被C酶磷酸化后,A受体活性增强。为验证T的磷酸化能增强神经细胞对刺激的“记忆”这一假设,下列步骤中对达成实验目的非必要的是A.用T的磷酸化位点发生突变的小鼠和未突变小鼠作实验材料B.HFS处理两组实验小鼠的H区传入纤维C.检测H区神经细胞突触后膜A受体能否磷酸化D.检测和比较两组小鼠突触后膜电位变化
