频度副词的用法练习
Unit 4 Time to celebrate--单元语法：频率副词和一般现在时+练习(教师版)
外研版七年级上册新教材（讲义）Unit 4 Time to celebrate重点语法--频率副词和一般现在时在英文中用来表示动作频率的词被称为“频度副词”，例如：usually/sometimes/always/等，这些词在程度上有区别。
语法点讲解1. 意义：表示动作发生的次数、频率的副词。
always, sometimes, never,usually，often ...常用频度副词的频率排序：always 100%usually 90%normally 80%often 70%sometimes 50%occasionally 30%seldom 20%hardly ever 5%never 0%2. 频度副词出现的位置（用法）：1.频度副词通常放在实意动词之前（1），be动词之后（2），如果句子中出现情态动词或助动词，则放在情态动词、助动词与实意动词之间（3）。
如：I always do homework in the afternoon.（1）He is never kind to us.（2）She can never know your secret.（3）2.频度副词的特殊位置：表示次数的频度副词，如once, twice，可以放在动词后或句末（4）；有的频度副词也可放在句首表示强调（5）。
如：The car broke down twice.（4）Sometimes I go fishing with my dad.（5）3. 常用频度副词精讲：1. always 频率最高，表示动作重复、状态继续，表示“一直、总是”，其反义词为never。
always等与not连用时，表示部分否定。
如：The rich are not always happy. 有钱的人并不总是快乐的。
如果要变为否定句，应将always改为never才能全部否定。
如：Li Ping is always late for school. 李平上学总是迟到。

通常说来，always表示100%，usually表示80%，often表示60%，sometimes表示40%，seldom表示20%，never表示0%。
1. always是频度最高的词，表示动作的重复，状态的继续，中间没有间断。
意为“总是、一直”，其反义词是never。
当它与现在进行时连用时，常译作“老是”，“总是”，带有赞扬、厌烦、不满等感情色彩。

▲ What do you usually do on Sundays? 你星期天通常干什么？▲ I usually got up at six in the morning last term. 上学期我通常在早上六点钟起床。
3. often意为“经常、常常”，不如usually那么频繁，表示动作重复，中间有间断，反义词为seldom。
▲ They often go for a walk after supper. 晚饭后他们经常去散步。
▲ My parents often take me to the zoo on weekends. 我父母常常在周末带我去动物园。
4. sometimes意为“有时、不时”，表示动作偶尔发生，中间常有间断，频率比often低。
▲ Sometimes they play football on Saturday afternoon. =They sometim es play football on Saturday afternoon. =They play football on Saturday afternoon sometimes. 他们有时在星期六下午踢足球。
