| Tom and Jack are next door neighbours who all work in same office, so they often walk together to and from work. One afternoon, they was walking home together while it started to rain. Tom quickly opened his umbrella and said proud, "My wife really has great foresight (远见). She said this morning it will rain and told me carry my umbrella with me." Jack smiled and walked closely to him under the protection of Tom's umbrella and said, "My wife has more greater foresight. He didn't let me carry mine and told me to use yours." | 1._________ 2.________ 3._________ 4. _________ 5. _________ 6. _________ 7. _________ 8. _________ 9. _________ 10. _________ |
