With so many stars in the universe, are we alone,or is there life out there in space .
alone/lonely 这两个词看上去很相似,实际上意思是不同的. alone只是陈述一个客观事实,意思是“独自一人”、“没有同伴或助手”,只用作表语.有时放在名词或代词后,表示“仅仅”、“只有”,可作形容词.例如： He was alone in the house. 他独自一人在屋子里. I’m not alone in this opinion. 不只是我一人有这种想法. He alone knew about this. 只有他一个人知道这事. 另外,alone 可用作副词,表示“独自地”、“单独地”.例如： The boy can do it alone. 这男孩能单独做这事. My sister lives alone. 我姐姐只身独居. lonely 则有浓厚的感调,指因缺少朋友、同情、友谊时所发生的一种悲伤的和忧郁的感情,意思是“孤独”、“寂寞”,作形容词.例如： He felt very lonely when he left his family. 当他离开家后,他感到非常孤独. I was alone,but not lonely. 我虽单独一人,但是并不寂寞. 注意,lonely 有时也可作定语,一般只修饰表示地点的名词,如a lonely village一个偏僻的村庄.
