分析：本句是一个主从复合句。whether引导宾语从句，作find out的宾语；if引导条件状语从句；“a certain event was happening in several days rather than years”是省略了that的宾语从句，作told的宾语。

译文：研究人员也试图弄清楚如果人们被告知某事将在几天而不是几年后发生，他们是否会更快采取行动。

5．What did Oyserman and Lewis intend to do through their study?

A．To work on a solution to test if someone is a procrastinator.

B．To find out whether human beings usually have two different characters.

C．To discover procrastinators are more likely to have a lower sense of well­being.

D．To prove it's helpful to connect our current selves more with future selves.

解析：D　考查细节理解。根据对第三段的整体理解可知，Oyserman和Lewis想要通过他们的研究去验证把“现在的我”和“将来的我”联系起来是否会对应对拖延症有一定的帮助，故选D项。

6．The underlined part “this way” in Paragraph 4 refers to “________”．

A．setting up tough deadlines

B．following schedules strictly

C．counting in smaller units of time

D．imagining how your future self will feel

解析：C　考查词义猜测。承接第三段最后一句“They made ‘Present Me’think about a far­off event a number of days away, not months or years”可推知，画线部分是指用更小的时间单位去计量，故选C。
