考研英语长难句精析—DAY150(考研英语长难句精解100句百度云)

【结构分析】
先抓主干部分，再看修饰部分。
本句主干是scientists… should not be distracted by…，其中scientists是主语，后面是“who know exactly where they are going and how they will get there”定语从句修饰，谓语动词是被动语态should not be distracted by，the necessity是宾语，“of keeping one eye on the cash register while the other eye is on the microscope”引导结构做定语。

句首的简单句的主语用的是形式主语it，真正的主语是for后面的部分。believe后面跟的是一个that引导的宾语从句。我们把这个句子再进行详细切分如下：
active learning// inwhichstudents write essays or perform experiments and then have their work evaluated by an instructor//, is far more beneficial // for those who have not yet fully learned //how to learn.

【重点词汇】
entirely reasonable 完全有理由
keep an eye on sth. 关注… 留意…

【参考译文】
审计员完全有理由相信有着明确目标并且知道如何实现目标的科学家不应该被这种必要性分心：一只眼睛盯着收银机，同时另一只眼睛盯着显微镜。
