Your other dinner companion should have the chance to talk to you.,4.If I were a boy again, I would practice perseverance oftener, and never give up a thing because it was hard or inconvenient.,5.Pigeons have a natural instinct to return home, even if they are far away and the trip is hard or dangerous.,1.The female mosquito is a vampire and lives on blood.,如不知道vampire的詞義, 從上文1ives on blood(靠吸血而生存)則可得知其詞義為吸血昆蟲。,2.The old man put on his spectacles and began to read.,如不知道spectacles的詞義, 從下文“戴上'spectacles'后開始閱讀“可猜得其詞義為“眼鏡“。,3.I'm sorry I've been monopolizing you.
