爱华网一般现在时态
一、主要用于下面几情况：
1)描述当前时间内经常出现、反复发生的动作或存在的状态。
在这种情景中，句子常带有表示频率的时间状语：always,everyday,often,onceaweek(month,year,etc.),sometimes,seldom,usually等等，以表示句中的动作或状态是习惯性的、经常性的。例如：
Shedoesn'toftenwritetoherfamily,onlyonceamonth.她不常给家里写信，仅一月一封而已。
Icycletoworkeveryday.我每天骑自行车上班。
2）仅为了描述状态、性质、特征、能力等等。
这里的目的是为了"描述现阶段的动作或状态"，其重点"不是强调动作发生的时间、或进行的状态"。例如：
Hecanspeakfiveforeignlanguages.他能说五种外语。
Thatisabeautifulcity.那是座美丽的城市。
Shemajorsinmusic.她主修音乐。
Allmyfamilylovefootball.我全家人都喜欢足球。
Mysisterisalwaysreadytohelpothers.我妹妹总是乐于助人。
3)陈述客观事实、客观真理。
顾名思义，客观的情况是"没有时间概念"的；也"不会在意动作进行的状态"。例如：
Theearthgoesaroundthesun.地球绕着太阳转。
Lighttravelsfasterthansound.光的速度比声音的速度快。
4)根据英文语法规定，当主句的谓语动词是一般将来时，那么时间或条件状语从句的谓语动词只能用一般现在时来表示将来要发生的动作。例如：
I'lltellhimthenewswhenhecomesback.他回来时，我将告诉他这个消息。
Ifyoutakethejob,theywilltalkwithyouingreaterdetails.
如果你接受这份工作，他们将和你谈谈细节。
用于一般现在时的副词，除了上面提到的一些表示频率的以外，常见的还有：now,today,nowadays等等。
