In places like India, the peacock is considered lucky because the great many “eyes” on its feathers are said to alert it to 23 evil.
答案：(B) approaching
alert sb to sth 的 to 是介系詞，後面須接名詞，故空格要填修飾 evil 的現在分詞 approaching（逼近的）；approach 與 be approaching 都是動詞形式，approached 為被動意味，均不合。
答對率 36%。
看到空格前面的 to，你大概直覺要接原形動詞，於是選 approach。但這個 to 不是不定詞，是片語 alert sb to sth（提醒某人注意某事）自帶的介系詞——後面要接名詞。
遇到空格前有 to，先看前面那個動詞的字詞搭配。若動詞本身要求接 to（alert sb to、look forward to、be used to、object to、devote oneself to），那個 to 就是介系詞，後面接名詞或 V-ing。國中學過的 look forward to seeing you、be used to getting up early 就是這條規則。
to 後面的名詞是 evil，空格夾在中間，要填修飾 evil 的形容詞——approaching（正在逼近的）。
alert sb to sth（提醒某人注意某事）、look forward to + V-ing（期待）、be used to + V-ing（習慣於）、an approaching storm（逼近的暴風雨）。
Much like the dove and robin, the bluebird is considered a very lucky sign in most cultures, particularly when seen in the spring. 21 , a woodpecker, when seen near the home, is regarded as a good sign. In contrast, the peacock is not 22 seen as lucky. In places like India, the peacock is considered lucky because the great many "eyes" on its feathers are said to alert it to 23 evil. Peacocks are also highly valued in China and Japan, where they are kept as symbols by the ruling families to 24 their status and wealth.
However, the peacock receives only scorn from the rest of the world. The feathers of peacocks are considered the most 25 part of the bird because the eye-shaped markings on them are associated with "evil eyes." To bring the evil eye into the home is thus believed to invite trouble and sorrow.
