八年级英语上册Unit1Howoftendoyouexercise知识点总结人教新目标版

⼋年级英语上册Unit1Howoftendoyouexercise知识点总结⼈教新⽬标版Unit 1 How often do you exercise1．What do you usually do on weekends? 你周末常常做什么？（1）这是⼀个由疑问词what引导的特殊疑问句。

前⼀个do为助动词，构成疑问句结构，后⼀个do为实义动词（或叫⾏为动词），意思是“做；⼲”。

注意：助动词do要随着主语的⼈称、时态和数的不同作出相应的变化。

如：▲What does she do on weekends? 周末她做什么？（2）usually为频率副词，意思是“通常；经常”，与often意思相近，但程度有别。

【辨析】：频率副词always, usually, often, sometimes, hardly ever, never【拓展】频率副词always的⽤法：在所有的频率副词中，always语⽓最强，表⽰“总是；永远”。

①always可⽤于进⾏时态，表⽰“⽼是；总是”，是⼀种加强语⽓的说法，含有“⽓愤；不满；不耐烦；赞赏”等感情⾊彩。

如：▲He is always coming late. 他总是迟到。

（埋怨）▲ He is always helping others. 他总是帮助别⼈。

（赞扬）②always通常放在be动词后⾯，⾏为动词前⾯，⼀般不放在句⾸。

但为了强调或在祈使句中，也可放在句⾸或放在整个谓语前⾯，有时甚⾄置于句末。

如：▲ Always pay attention to your pronunciation. 要始终注意发⾳。

③always与not连⽤时，表⽰部分否定，意思是“不⼀定总是；未必”等。

如：▲ Honesty is not always the best policy. 诚实未必永远是上策。

（3）on weekends 意思是“在周末”，也可说成at (the) weekends, 此处的weekends指星期六和星期⽇。
