一、行为动词的一般现在时常和表示频率的副词连用，英语中usually , sometimes, always, often, never等词被称为“频度副词”，是用来表示动作频率的，但在程度上有差别。一般来说可按频率大小排列：
always（总是）>usually（常常）>often（经常）>sometimes（有时） >seldom（很少）>never（从不） 二、频度副度在句中的位置。 1. 在be动词之后。
Boys are always good at playing computer games. 男孩子们总是擅长玩电脑游戏。

动词的现在进行时态
英语中动词和汉语中的动词不同，英语中动词有单复数、时态等方面的变化。根据动词发生的时间不同有不同的时态。
一、现在进行时的构成
1. 现在进行时由“be+动词的现在分词”构成。Be为助动词，本身无意义，与主语的人称和数保持一致。变疑问句时把助动词be提到主语之前，变否定句时在be后加not。
I am sending an email to the Internet. （陈述句） 我在网上发电子邮件。
Are you sending an email on Internet? （疑问句） 你在网上发电子邮件吗？
I am not sending an email on the Internet. （否定句） 我不在网上发电子邮件。 2. 现在分词的构成规则： go--going ask--asking look--looking have--having take--taking 以不发音的e结尾的动词，去掉e加-ing make--making write--writing get--getting sit--sitting 以一个辅音字母结尾的重读闭音节，双put--putting 写最后一个字母再加-ing run--running shop--shopping 以ie结尾的动词，要把ie变成y，再加lie--lying die--dying -ing 二、现在进行时的用法。 1. 表示说话时正在进行或发生的动作，常与now（现在），at the present（现在），at the moment（此时此刻）等时间状语连用。
I am buying some postcards now. 我正在买一些明信片。
Lily and Lucy are enjoying the sun on the Great Wall at the moment. 莉莉和露西正在长城上享受阳光。
2. 表示现阶段正在进行而说话时不一定正在进行的动作，常与today（今天），this week（这个星期），this year（今年）等时间状语连用。
We are working in a factory these days. 这几天我们在一家工厂工作。 Mr. Wang is writing a book this year. 今年王先生在写一本书。
3. 句中没有时间状语，通过上下文暗示用动词的现在进行时态。 （1）通过祈使句暗示。 Look! What are they doing? 看！他们正在做什么？
Listen! A bird is singing in the tree. 听！树上有只小鸟在唱歌。
18
一般情况下在动词词尾加-ing （2）通过陈述句暗示。
It’s five o’clock. People are going home from work. 5点钟了。人们正在下班回家。
I’m watching TV and my father is reading a newspaper. 我在看电视，我爸爸在看报纸。 （3）通过特殊疑问句暗示。 Where are Daming and Lingling? 大明和玲玲在哪里？
