精品解析：【单元热点难点】译林版（三起）英语五年级上册Unit 7 At weekends 语法划重点

【讲练结合】五年级上册英语Unit7 My weekends语法划重点 1. 语法精讲 一、always, usually, often, sometimes的用法 always,usually,often,sometimes都是用来表示时间的频度副词,但它们所表示的动作频率不同。 通常说来,always表示100%,usually表示80%,often表示60%,sometimes表示40%。 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。如:He always helps me. 他总是帮助我。 2. usually意为“通常”,表示通常如此,很少例外,频度仅次于always。 如: I usually get up at six in the morning. 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。 如:My parents often take me to the zoo at 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. 他们有时在星期六下午踢足球。 =They sometimes play football on Saturday afternoon. =They play football on Saturday afternoon sometimes. 注意 :一般情况下,这四个词都位于行为动词之前,be动词、助动词或情态动词之后。  sometimes的位置较灵活,可以放在句中,也可以放在句首或句末。 补充:always > usually > often > sometimes > seldom 偶尔 > neve从不 对这些频率副词提问时,用 how often。如:How often do you watch films? 其他频率副词:once(一次)twice(两次),once a week 一周一次,twice a day 一天二次 二、询问某人在周末做什么的句型 —What (do /does ) +主语+ do at weekends?     答句:—主语+动词原形/动词三单形式……. ★do / does: 助动词,由主语的人称数而定. 主语是第三人称单数时,用does, 主语是第一人称、第二人称、第三人称复数时,用do. ★答句: 如果主语是第三人称单数,则要用动词三单形式；主语是第一人称、第二人称、第三人称复数时用动词原形。 三、一般现在时的特殊疑问句修改方法: (1)找出特殊疑问词。(2)改为一般疑问句,尤其注意第三人称单数,借助does,动词变原形。(3)去掉划线部分,句子合并。 2.专题训练 用often, always, sometimes填空。 1.
