二、用法详解与例句

1. In a row

核心逻辑:突出“连续的次数/时间段”,常回答“how many times consecutively”(连续多少次)的问题。

常见搭配:数字 + in a row(如3 times in a row, 5 days in a row)。

例句1(现在完成时,接次数)

She (主语)

has won the math competition three times in a row (谓语:has won,现在完成时,表“到目前为止连续发生的结果”;状语:three times in a row,表连续次数)

since she entered the middle school (时间状语从句:since引导,主句用现在完成时,从句用一般过去时“entered”)。

例句2(一般过去时,接时间段)

The factory (主语)

stopped production for a week in a row (谓语:stopped,一般过去时,表“过去发生的连续动作”;状语:for a week in a row,表连续时间段)

because the raw materials were in short supply (原因状语从句:because引导,时态与主句一致,用一般过去时“were”)。

2. Constantly

核心逻辑:突出“动作反复、状态持续”,常回答“how frequently”(频率如何)的问题。

常见搭配:修饰动词(如work, complain, rain),体现动作的“持续性”。

例句1(现在进行时)

My little brother (主语)

is constantly asking me for storybooks (谓语:is asking,现在进行时,表“当前正在持续的动作”;副词:constantly,修饰ask,表“反复询问”)

while I am doing my homework (时间状语从句:while引导,主句用现在进行时,从句也用现在进行时“am doing”,表“同时进行”)。

例句2(一般现在时,表习惯性动作)

He (主语)

constantly checks his phone for messages (谓语:checks,一般现在时,表“习惯性动作”;副词:constantly,修饰check,表“频繁、持续检查”)

even when he is having meals (让步状语从句:even when引导,从句用现在进行时“is having”,表“即使在吃饭时也持续”)。

三、练习题与解析

练习题

用 “in a row” 或 “constantly” 填空,并分析句子结构与时态。

1. The team ______ (win) five games ______, which makes all the fans excited.

2. The old man ______ (talk) about his past experiences ______ when he meets his friends.

答案与解析

1. The team has won five games in a row, which makes all the fans excited.

解析:空格后有具体数字“five games”,强调“连续次数”,用“in a row”;“赢5场比赛”是“到目前为止的结果”,用现在完成时“has won”(主语the team为单数,谓语用has won);定语从句“which指代‘赢5场’这件事”,用一般现在时“makes”表当前的影响。

2. The old man talks about his past experiences constantly when he meets his friends.

解析:句子强调“见面时反复谈论”的频率,无具体次数,用“constantly”;“meet friends”是习惯性场景,主句用一般现在时“talks”(主语the old man为单数,谓语用talks);时间状语从句“when引导”,用一般现在时“meets”与主句时态一致。

四、总结:

1. 看是否有“具体数字(次数/时间段)”:有数字→用 in a row;无数字、侧重“反复频率”→用 constantly。

2. 看时态搭配:表“连续结果”(完成时)或“过去连续动作”(一般过去时)→用 in a row;表“持续动作”(进行时)或“习惯性反复”(一般现在时)→用 constantly。

3. 看核心含义:强调“连续的次数/时间段”→ in a row;强调“动作持续、反复发生”→ constantly。
