2017届高考英语一轮复习夯实训练：Unit 21《Human Biology》（北师大版含解析）

　　1．which　[考查定语从句。引导非限制性定语从句，在从句中作主语。]

　　2．Using　[考查非谓语动词。分析句子结构可知， use在句中作主语，故用动名词形式。]

　　3．but　[考查连词。前后语义为转折关系，故用but。]

　　4．possesses　[考查主谓that引导的定语从句，a face－to－face conversation作主语为单数故谓语用possesses。]

　　5．greatly　[考查副词。修饰动词affect要用副词。]

　　6．is thinking　[考查动词时态。think 和从句主语the other person 构成逻辑上的主谓关系，且从句缺少谓语，且后有and feeling，故用进行时is thinking。]

　　7．be applied　[考查语态。Facial expression与apply为动宾关系用被动语态。前面有can，系动词用原形。]

　　8．features　[考查名词。前有形容词physical，故用名词feature复数形式。]

　　9．to comfort　[考查非谓语动词。此句中can be 为谓语，空处为非谓语，to do表目的。]

　　10．between　[考查介词。在交流双方之间用between。]

　　(2016·成都诊断)Many years ago, an experiment in education was carried out in secret at a school in England.The school had two classes for children of the same age.At the end of the school year an examination was held, in order to select the children for the classes of next year.However, the results of the exam were never made known.In secret, based on their performance in the exam, the higher performing and lower performing children were divided equally between the two classes.Only the headmaster and the psychologists knew the truth.Teachers for the next year were carefully selected for equal ability and experience.Even the classrooms were chosen with similar facilities (设备).Everything was made as equal as possible, except for one thing: one was called “Class A”， the other, “Class B”.
