（五）重点、难点分析
1. 过去进行时：表示在过去某一时间内正在进行的动作。
构成：was / were + 现在分词（其中was是am、is的过去式，were是are的过去式）
eg. 1) I was doing my homework then . 那时，我正在做作业。
    2) He was cooking in the kitchen at 12 o'clock yesterday .昨天12点，他正在厨房烧饭。
用法：1）过去进行时表现过去某一时刻正在进行的动作。
eg. She was writing a letter when I came in .我进来时，她正在写封信。
2）过去进行时还表示过去某阶段正在进行的动作。
eg. They were waiting for you yesterday .他们昨天一直在等你。
2. 现在分词的构成
1）一般动词在词尾加-ing，读[iη]，如go→going。
2）以不发音字母e结尾的动词，先去掉e，再加-ing。
   come→coming     make→making    write→writing
3）以重读闭音节结尾的动词，如果末尾以一个辅音字母结尾，应先双写这个字母，再加ing，x和w结尾的除外。
   如get→getting   swim→swimming  show→showing
4）以字母y结尾的单词，直接加ing。
　 如carrying、playing、studying。
5）以字母ie结尾的动词，变ie为y，再加ing。
   die→dying   lie→lying
6）以元音字母加e结尾，或以e结尾，且e发音的动词，直接加-ing 。
   see→seeing  be→being
3. 使用进行时态的注意事项
1）一些动词，如see、hear、love、like、know、remember；understand、have等表示感情、知觉和状态的词，一般不用于进行时态。
2）在there和here引起的句子中，常用一般现在时代替现在进行时。
   eg. Here comes the bus .
       There goes the bell .
4. 过去进行时和一般过去时的区别
1）过去进行时表示过去正在进行的动作，而一般过去时则表示一个完整的动作。如：
   They were writing letters to their friends last night .昨晚他们在写信给他们的朋友。（没有说明信是否写完）
   They wrote letters to their friends last night .他们昨晚写了信给他们的朋友。（表达了他们已写好的意思，整个写的过程已完成。）
2）当动作延续较长时间时或表示厌烦、赞美等感情色彩时，常用过去进行时表示。如：
   He was thinking more of others than of himself .他考虑别人的比考虑自己的多。（表示说话者赞扬的口气）
   The boy was always making trouble then .那时，他总是惹麻烦。（表示说话者厌烦的口气）
5. 以when和while引导的时间状语从句
1）延续性动词和非延续性动词
延续性动词指动作可以延续一段时间，而不是瞬间结束。如：work、study、drink、eat等。
非延续性动词指动作极为短暂，瞬间结束。如：start、begin、hit、jump、knock等。
2）在本单元中，出现了以when和while引导的时间状语从句。
<1> when表示“当……的时候”。从句中既可用延续性动词，又可用非延续性动词，这些动词既可以表示动作，又可表示状态。从句中的动作既可和主句的动作同时发生，又可在主句的动作之前或之后发生。如：
Mary was having dinner when I saw her .
The boy was still sleeping when his mother got home yesterday morning .
<1> while表示“在……的时候”、“在……期间”。它强调主句的动作与从句的动作同时发生或主句的动作发生在从句的动作过程中。while从句中必须是表示动作或状态的延续性动词。如：
The weather was fine while we were in Beijing .
She called while I was out .
如果主句的动作在从句的动作过程中发生，从句常用进行时。如。
While we were swimming someone stole our clothes .
Don't talk so loud while others are working .
总结：
<1> when可指时间点，又可指时间段，从句中可用延续性动词，也可用非延续性动词。
<2> while总是指一个时间段，从句中必须用延续性动词。
6. In this unit , we'll learn how to tell a story . Let's take section B 3a as an example .
1）Listen to this story 听这个故事
Linda Jacobs loves her dog Davy . They went to New York City last Saturday . While Linda was buying a newspaper at the train station , the dog got out of his box and ran away . The station was crowded and Linda couldn't see Davy anywhere . When Linda shouted his name , some people looked at her but Davy didn't come . Then she called the police .

The Bermuda Triangle

The three points of the triangle （三角形）known as “the Bermuda Triangle” are Bermuda, Florida and Puerto Rico．From 1945 until the present day over 1,000 lives have been lost in this area without trace （痕迹，踪迹）─ no bodies have ever been found!

The most remarkable （显著的）loss was a group of six US Navy planes in 1945．Five of these were>Many small boats and light aircrafts have vanished （消失）in this area．But so have large ships．What makes these losses even more mysterious （神秘的）is the fact that hardly SOS signals are ever received from the ships and boats which disappear．Also, these things happen in good weather and without warning．Ships just seem to vanish into thin air．This fact has led some people to suggest all sorts of strange explanations．For example, some people believe that the planes fly into a “hole in the sky” from which they are unable to escape．Others think that the ships that have disappeared have been the victims （牺牲）of beings from outer space who have snatched （攫取）them from the surface of the sea and taken them to some unknown world!

More reasonable people say that the large number of losses in this area can be explained more simply．They say that the extreme weather conditions which occur in this part of the world are the reason why so many ships and planes disappear in this area．For instance, huge freak （反常的，奇异的）waves can form quite quickly and these can crush （压碎，碾碎）a ship before it has time to escape．Also waterspouts are found in this area．These are similar to cyclones （过滤器）but because they are over the ocean they form a great column of water which can be over 60 meters high．They could destroy a small ship or plane．

Some people point out that the Bermuda Triangle is>Some people even say that the Bermuda Triangle does not exist and that all the accidents that have happened there are simply coincidences．
