30、。幸亏一位好心人的帮助，鼓起了我的信心。1A由后面的and had to go to hospital for a.examination可知是身体出了问题。2Dscientific意为“科学的”；final意为“最终的”；previous意为“先前的，以前的”；thorough意为“彻底的，完全的，细致的，深入的”。身体不适，到医院做“细致的”检查符合语境。3B身体的不适与我目前所面临的一件事相比仅仅是个小小的“挑战”。4Ago wrong意为“出毛病，弄错”，与后文的乘错公共汽车等相符。5C没有车，也不熟悉这个城市。leave意为“离开”；visit意为“参观，访问”；know意为“知道，

31、了解，熟悉”；appreciate意为“感激，欣赏”。由短文开头第一句话When I settled in Chicago，.可排除A、B两项；D项不符合句意。6A由我给自己留有足够的时间，到was going to be late可知需用Although。7C由于我上错了车，很明显我要迟到了。strange意为“奇怪的”；necessary意为“必需的”；obvious意为“明显的”；important意为“重要的”。C项符合句意。8D由于上错了车，再由后文的where a bus would take me back into the city可知车子把我拉向一个相反的方向。9C由and

32、stood on the pavement not knowing what to do可知是从公共汽车上下来了。10C由于是刚迁移到这个城市，人地两生，由后面的信息可知这是“陌生人”。11B由后面的信息，陌生人没有直接走过去，而是停下来问我好不好。我感到“很惊讶”，符合语境。12Cnervous意为“紧张的”；excited意为“激动的，兴奋的”；OK意为“好的”；dangerous意为“危险的”。只有C项符合句意。13D我向她解释了我的“处境，情况”。14A她指向对面的公共汽车站台，那边有辆公共汽车能把我带回到我要去的地方。appointment在这里指约定的那家医院。此题易误选C。要去的

33、是医院，而不是“方向”。15B在这陌生的城市有人愿意帮助我，我很感激。符合情理。16B接下来，我听到附近有汽车喇叭声。then表示时间顺序，承接上文。17C我抬头看见我的新朋友在车里向我招手。18A她是返回来送我去医院的。offer sb. a lift to意为“让某人搭便车，用车送某人去某地”，为固定搭配。19C这样得到路人意外的好心帮助，是令人欣慰的礼物。20B她微笑着叫我不要失去信心，因为一切皆有可能。faith意为“信念，信仰，信心”，符合句意。.语法填空Doctor：Have a seat please.

Do you take any exercise?Patient：No. I never have enough time for exercise. Can you give me some medicine?Doctor：I can,

37、 but Im not going to. You dont need medicine. You need advice. Dont work so hard. If you think your present job is too hard, find an _9_(easy) one. Anyway, its more important to be healthy than_10_(wealth)答案与解析1tired修饰人用ed形式的形容词。2whenwhen 引导时间状语从句，意为“当时”。3appetitehave no appetite 没有食欲。4untilnever.un

38、til.直到才。5taken现在完成时用 have done。6making动名词作宾语。7offtake off 脱下。8nothingthere is nothing wrong with you.你没有病。9easier根据上下文可知用比较级。10wealthy本空为(to be) healthy 对应，故用 wealthy。.短文改错Today is Sunday.
