Test analysis: this question examines the ability to use words (including idioms) correctly, and the ability level is E. Wind and rain do not change: describe people who often work hard outside regardless of wind and rain. Obviously it doesn't match the meaning of the sentence, and this word can't be used as an attribute. Charm: describe the charm of women. It is ok to describe Mei Lanfang here because she plays the role of an actress. Courtesy in court: Originally, it means that the host and the guest meet, stand on both sides of the court and salute each other. Now the metaphor is equal and equal. Out of context. Look sideways: Look at people sideways. Describe hatred or fear and resentment. Very arrogant, obviously inappropriate.
