16．Did you have any  interesting dreams last night？Do you know everyone dreams？But not everyone remembers their dreams．A person can usually have up to seven dreams a night，and each dream usually lasts from 10to 40minutes．
Why do we dream？Scientists believe that we dream to remember because dreams come from our memories and they tell us a lot about ourselves．They also help us learn from the past and even help us solve problems．
Different dreams mean differently to people．For example，if you dream about flying，you are probably quite happy．This is a good time in your life．You may feel that other people see you as a leader．And when you dream that you didn't study for a test，it usually means you are worried about an important thing coming in your life．

分析 文章大意：本文講述的是"夢"．一個人通常一晚上做七個夢，每個夢通常持續(xù)10至40分鐘．為什么要做夢？科學(xué)家認為做夢是為記憶，因為夢來自我們的記憶并告訴我們許多有關(guān)自己的事，幫助我們從過去中學(xué)習(xí)甚至幫助解決問題．不同的夢對人有不同的含義．

解答 46題答案：seven  細節(jié)題．由短文第1段的第4句：A person can usually have up to seven dreams a night人一晚上通常共做七個夢可以知道本題填：seven．
47題答案：remember 細節(jié)題．根據(jù)短文第一段中的"Do you know everyone dreams？But not everyone remembers their dreams．"你知道大家都做夢嗎？但是不是每個人都記得他們的夢可以推測出，這里填：remember．
48題答案：why/we/reason（s） 細節(jié)題．從后面所給的a、b兩點：a．to remember（記憶）；b．to solve problems解決問題）可以推測出，這里歸納的是人們做夢的原因．故可以這里填：why/we/reason（s）．
49題答案：dream（s）  細節(jié)題．從后面的要點，一是飛的夢；二是考試不及格的夢．可以推測這里歸納的是"夢的例子"，夢的例子，故填：dream（s）．
50題答案：happy 細節(jié)題． 由最后一段的"if you dream about flying，you are probably quite happy．"如果你夢見飛，你可能相當(dāng)快樂可以推測出，這里填：happy．

點評 本文是一篇日常生活類閱讀，題目涉及多道細節(jié)理解題，做題時結(jié)合原文和題目有針對 性找出相關(guān)語句進行仔細分析，結(jié)合選項選出正確答案．推理判斷也是要在抓住關(guān)鍵句子的基礎(chǔ)上合理的分析才能得出正確的答案．
