Reading Comprehension 
Read the quoted parts carefully and answer the questions in English. “Shall I compare thee to a summer’s day?
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer’s lease hath all too short a date:”
What figure of speech is employed in the poem?
【正确答案】：

PERSONIFICATION

【题目解析】：引文中的修辞手法是拟人。引文“或许我可用夏日把你来比方，但你比夏日更可爱也更温良（Shall I compare thee to a summer’s day? Thou art more lovely and more temperate）” 中，lovely（可爱）和temperate（温和的）多用于形容人的性格，所以是把夏天比作人，来对比衬托作者描写之人的美好之处。
