“It + be + 时间名词+before / since”从句句型中用before引导时，句意是 “过了多久才……”，主句中的be动词为过去时或将来时态；用since引导时，其句间是“自从……以来已经多久了”，主句中的be动词多为现在时(或现在完成时)或一般过去时。

By the time a student starts to apply (申请) for a US university, much of his or her record, including grades and after-school activities, has been set in stone. For this reason, the student must in his or her first year of high school start getting ready for college. He or she also has to decide on the non-academic (非学业的) tasks, which are important to improve the student’s chances of getting in.
1. After-school activities
When it comes to high school activities, quality is better than quantity (数量). Admissions (录取) officers do not want to see a student who has joined dozens of organizations (组织) for a short period of time.
Many students try to do this towards the end of their high school. But schools want to see a student who has been with one organization for all or most of high school. A student who can do this shows maturity (成熟). It is the quality that admissions officers look for as it is one of the markers of future success.
2. Leadership
Schools want to see a student who has taken on a leadership role in an organization. A student can show leadership by taking on any role that needs extra commitment (奉献) and responsibility.
If you do not have a great title (头衔) such as president, be sure to explain any leadership roles you have taken. This kind of involvement (参与) in school activities shows you are the responsible person that admissions officers look for.
3. Consistency (一致性)
Admissions officers like an application (申请) to be consistent. For example if there is a high school activity you particularly (特别地) love, it would help if that activity matches your future academic and career interest.
Of course not everything needs to be consistent. Otherwise (否则) the student would be narrow and this is not what schools are looking for. However, you cannot have different parts of your application saying conflicting (矛盾的) things.
