考点 01
一般现在时(描述日常习惯)
1.动词形式的 “两情况”
(1) 情况 1:主语是 “非三单”:包括第一人称(I/we)、第二人称(you)、复数名词(如 my grandparents、the children),动词用原形。例:We visit my grandparents every Sunday.(我们每周日看望祖父母。)(主语 we 是第一人称复数,“visit” 用原形,对应 “每周日” 的日常习惯)
(2) 情况 2:主语是 “三单”:包括第三人称单数(he/she/it)、单数名词(如 my mother、this park)、不可数名词(如 the water),动词需变 “三单形式”。例:My mother washes clothes every Saturday.(妈妈每周六洗衣服。)(主语 my mother 是单数名词,“wash” 变三单 “washes”,体现 “每周六” 的固定习惯)
2.三单动词变形的 “三类规律”
变形类型
规则
例词(原形→三单)
五年级易错题提醒
一般情况
直接加 s
visit→visits、play→plays
注意 “s” 发音:清辅音后读 /s/(如 visits),浊辅音 / 元音后读 /z/(如 plays)
以 s/x/ch/sh/o 结尾
加 es
wash→washes、fix→fixes、watch→watches、go→goes
不要漏加 “es”,比如 “do” 的三单是 “does”,不是 “dos”
以 “辅音 + y” 结尾
变y 为i 加 es
study→studies、carry→carries
若以 “元音 + y” 结尾,直接加 s(如 play→plays),不要混淆
3.否定句与疑问句的 “两步法”(五年级新增难点)
(1) 否定句:非三单主语:主语 + don't + 动词原形例:They don't go to the park on weekdays.(他们工作日不去公园。)三单主语:主语 + doesn't + 动词原形(注意:doesn't 后动词必须变回原形)例:My father doesn't watch TV in the morning.(爸爸早上不看电视。)(易错点:不要写成 “doesn't watches”)
(2) 疑问句:非三单主语:Do + 主语 + 动词原形例:Do you play chess with your grandpa?(你和爷爷下棋吗?)三单主语:Does + 主语 + 动词原形例:Does your sister write e-mails to your grandma?(你姐姐给奶奶写邮件吗?)(易错点:Does 后动词用原形 “write”,不是 “writes”)

考点 02
频率副词的用法
1.频率副词的 “位置口诀”(必背)“实义动词前,be 动词后;助动词 / 情态动词后,实义动词前”
(1)情况 1:句子有 “实义动词”(如 visit、play、write),频率副词放实义动词前面。
例:I often play chess with my grandpa.(我经常和爷爷下棋。)(“play” 是实义动词,“often” 放前面)例:She sometimes writes e-mails to her grandparents.(她有时给祖父母写邮件。)(“writes” 是实义动词,“sometimes” 放前面)
(2) 情况 2:句子有 “be 动词”(am/is/are),频率副词放 be 动词后面。
例:They are always happy to see me.(他们见到我总是很开心。)(“are” 是 be 动词,“always” 放后面)例:My grandma is usually busy in the morning.(奶奶早上通常很忙。)(“is” 是 be 动词,“usually” 放后面)
(3) 情况 3:句子有 “助动词(do/does)” 或 “情态动词(can)”,频率副词放助动词 / 情态动词后面、实义动词前面。
例:Do you usually go to the park with your family?(你通常和家人去公园吗?)(“do” 是助动词,“usually” 放后面,“go” 前面)
例:He can sometimes help his grandma do housework.(他有时能帮奶奶做家务。)(“can” 是情态动词,“sometimes” 放后面,“help” 前面)
2.频率副词的 “程度排序”从 “频率最高” 到 “频率最低”:always(100%)> usually(80%)> often(60%)> sometimes(30%)> seldom(10%)> never(0%)
例:I always visit my grandparents on the Double Ninth Festival.(重阳节我总是去看望祖父母。)(“always” 体现节日固定习惯)
例:She seldom eats fast food.(她很少吃快餐。)(“seldom” 描述不常发生的动作)
3. 频率提问的 “核心句型”用 “How often” 提问 “多久一次”,回答时用 “频率副词” 或 “具体次数(once a week/twice a month)”。句型结构:How often + 一般疑问句?
例:- How often do you go to see your grandparents?(你多久去看一次祖父母?)
-I go to see them twice a month. / I often go to see them.(我一个月去两次。/ 我经常去看他们。)
例:- How often does your father play chess with your grandpa?(你爸爸多久和爷爷下一次棋?)
-He plays chess with my grandpa once a week. / He sometimes plays chess with my grandpa.(他一周和爷爷下一次棋。/ 他有时和爷爷下棋。)
