明智的做法是将 WHERE 子句发送至数据库，但是这意味着我们必须将谓语 p.Age < 18 转换成 SQL，并将其发送给数据库。

The sensible thing to do is to send the WHERE clause to the database, but this means that we would have to translate the predicate p.Age < 18 into SQL and send that to the database instead.

与此同时，还可以尝试向WHERE子句中添加额外的谓语来匹配其他WHERE子句。

In the meantime, you also should try to add extra predicates into your WHERE clause to match other WHERE clauses.

再加上指定测试条件的行，该语句就完整了，指定测试条件的行用来组成from子句以组成谓语。

This statement is then completed by the row specifying the test condition, which is also used to populate the FROM clause and additional the WHERE clause so forming a predicate.
