If y is an integer and y = |x| + x, is y = 0 ?
(1) x < 0
(2) y < 1
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

EACH statement ALONE is sufficient.
Statements (1) and (2) TOGETHER are NOT sufficient.
还没有题目讲解（毕出老师会陆续发布对官方考题的解读，请保持关注）。
这道题的条件二也是成立的，做的时候忽略了题目说了，y是整数，所以如果y是整数的话，x只能小于零的整数。
