是can never还是never can?傻傻分不清楚
频率副词告诉我们某件事在以前,现在以及未来发生的频率,比如always、often、usually,这些都是频率副词,那么该怎么用呢? always: Peter is always getting into trouble. 彼得总是遇到麻烦。 usually: They usually get their work done on time. 他们通常按时完成工作。 frequently: My sister frequently goes shopping in Seattle. 我妹妹经常去西雅图购物。 rarely: They rarely ask questions about the homework. 关于家庭作业他们很少提问。 频率由高到低: always:总是 He always does his homework. 他总是完成作业。 usually:通常 They usually complete the work on time. 他们通常按时完成工作。 often:经常 I often watch movies online. 我经常在网上看电影。 sometimes:有时候 Jack sometimes comes over for dinner. 杰克有时会过来吃饭。 occasionally:偶尔 She occasionally asks a question. 她偶尔会问一个问题。 rarely:很少 They rarely have any homework. 他们很少有作业要做。 never:从不 I never complain at work. 我在工作中从不抱怨。 那么,频率副词在句中应该放在什么位置呢?我们来看看下面的规则: 如果句子中有一个动词(例如没有助动词),我们通常将副词放在句子的中间,即在主语之后,动词之前: subject / adverb / verb / predicate 主语/副词/动词/ 谓语 Tom usually goes to work by car. 汤姆经常开车去上班。 Mary often asks me for help. 玛丽经常请我帮忙。 频率副词通常放在“be”动词之后: subject /be verb / adverb / predicate 主语/be动词/副词/谓语 Tom is often late. 汤姆经常迟到。 Anne isn't usually sick. 安妮通常不怎么生病。 Peter isn't always right. 彼得并不总是对的。 如果我们将频率副词放在句子的开头或结尾表示强调,则情况并非如此。而且此规则也不适用于简短回答: Is she usually on time? 她通常准时吗? Tell her not to be late. 告诉她不要迟到。 Yes, she usually is. 是的,她通常是。 She never is. 她从来不。 如果句子中有多个动词(例如助动词),我们通常将频率副词放在第一个动词之后: subject / helping verb or modal / adverb / main verb / predicate 主语/助动词或情态动词/副词/主动词/谓语 I can never forget his name. 我从来都不会忘记他的名字。 Anne doesn't usually smoke. 安妮通常不抽烟。 The children have often complained about the playground facilities. 孩子们经常抱怨游乐场的设施。 例外: 在含有“have to”的句子中,频率副词位于所有动词之前: 主语/副词/have to/主动词/谓语 We often have to wait for the bus. 我们经常要等公共汽车。 She never has to do any housework. 她从不做任何家务。 为了表示强调,我们可以将频率副词放在句子的开头或结尾。 首先,把它放在最后是很少见的。我们通常只在我们忘记把它放在开头时才把它放在结尾。 adverb / subject / main verb / predicate 副词/主语/主动词/谓语 Sometimes we go to school by bus. 有时候我们乘公共汽车上学。 Often he waits for her after class. 他经常在课后等她。 subject / main verb / predicate / adverb 主语/主动词/谓语/副词 We go to school by bus sometimes. 我们有时乘公共汽车去学校。 They like to watch TV often. 他们经常喜欢看电视。 例外情况: “Never”,“seldom”,“rarely”不能放在句子结尾。他们只用于“陈述”的句子开头。然后他们必须遵循疑问句的词序: Never has there been a better time to overcome our differences. 从未有过比这更好的时机来克服我们的分歧。 Rarely do we have an opportunity like this. 我们很少有这样的机会。 在疑问句中使用频率副词时,请将副词放在主动词之前: auxiliary verb / subject / adverb / main verb / predicate 助动词/主语/副词/主动词/谓语 Do you often go to the cinema? 你常去电影院吗? Do they usually come late to class? 他们经常上课迟到吗? 例外: 当在否定句中使用频率副词时,请将频率副词放在主动词之前: Subject / helping verb / adverb / main verb / predicate 主语/助动词/副词/主动词/谓语 They don't often go to the cinema. 他们不经常去电影院。 Peter doesn't normally want to come with us. 彼得通常不想和我们一起来。 你用错过频率副词吗? |
