高中英语语法精讲 ⑥|背口诀不如认标志:一般现在/进行/过去/将来一张表讲透
时态(一)|"我明天去北京",为什么答案能有三四种?
高中英语语法精讲 · 第 6 期
导语
先看学生作业里的一句原话:
❌ If it will rain tomorrow, the sports meeting will be put off.
时态词都对,语法分照扣。高三复习时态,问题往往不是"没学过",而是凭感觉选。从这篇起,我们用两把尺子——时间标志 + 语境——把时态题变成送分题。先把四种基础时态讲透。
一、先建立地图:四种基础时态考什么
北师大版必修一 Unit 1(Lifestyle)的语法板块就是一般现在时和现在进行时,高一学的是"是什么",高三要补的是"怎么判断、怎么不丢分"。
一句话定调: 时态题先找时间标志,没标志就看上下文语境,两把尺子够用 90% 的题。
二、10 个高频易错点
1. 时间、条件状语从句:主将从现
规则: 主句用将来时,if / when / as soon as / until 引导的从句用一般现在时表将来。
❌ I'll call you when he will arrive. → ✅ I'll call you when he arrives.(他一到我就给你打电话。) ❌ If it will rain tomorrow, we'll stay indoors. → ✅ If it rains tomorrow, we'll stay indoors.(如果明天下雨,我们就待在室内。)
口诀:主将从现——主句将来,从句现在。
注意: if 意为"是否"(宾语从句)时不受此限:I don't know if he will come.(我不知道他是否会来。)
2. 状态动词不用进行时
know, believe, love, hate, want, need, own, belong to 这类状态动词,本身就表示状态,不能"正在"。
❌ I'm knowing the answer. → ✅ I know the answer.(我知道答案。) ❌ This bike is belonging to my brother. → ✅ This bike belongs to my brother.(这辆自行车是我哥的。)
技巧:能说"想拥有"却不能说"正在拥有"的,多半是状态动词。
3. 时刻表将来:火车、航班、电影用一般现在时
按固定时刻表发生的动作(车次、航班、开课、开演),用一般现在时表将来。
The train leaves at 6:30 tomorrow morning.(火车明天早上六点半发车。) The film starts at 8 p.m. tonight.(电影今晚八点开演。)
技巧:能印在时刻表上的,用一般现在时;人自己计划的,用进行时或 be going to。
4. be going to vs will:有迹象 vs 临时决定
- be going to
:事先打算,或有明显迹象。Look at the dark clouds — it is going to rain.(看那些乌云——要下雨了。) - will
:说话时临时决定,或客观预测。— The phone is ringing. — I will answer it.(电话响了。——我去接。)
口诀:云来了用 going to,电话响了用 will。
5. come / go / leave / move:现在进行时表已定安排
位移动词用现在进行时,表示已经安排好的将来。
We are leaving for Shanghai next Friday.(我们下周五动身去上海。) My cousin is coming to stay with us during the holiday.(假期我表弟要来和我们住。)
技巧:车票已买、行程已定 → 进行时;只是打算 → be going to。
6. 客观真理永远用一般现在时
即使主句是过去时,科学事实、客观真理仍用一般现在时。
The teacher told us that the earth goes around the sun.(老师告诉我们,地球绕着太阳转。) Water boils at 100°C.(水在 100 摄氏度沸腾。)
技巧:内容是"永远成立的事",时态就不跟着过去走。
7. always + 进行时:不是"总是在做",是抱怨或赞叹
He is always losing his keys.(他老是丢钥匙。——抱怨) She is always helping classmates with their homework.(她总是帮同学讲题。——赞叹)
技巧:always + 进行时自带情绪,写作里用来刻画人物很加分。
8. just now(刚才)vs right now(此刻)
口诀:just now 往回看,right now 看眼前。
9. 一般现在表习惯,现在进行表现阶段
He usually walks to school.(他平时走路上学。——长期习惯) He is walking to school this month because his bike is broken.(这个月他走路上学,因为自行车坏了。——临时阶段)
技巧:usually / every day 配习惯用一般现在;these days / this month 配临时状况用进行时。
10. 没有时间标志时,看"叙述视角"
完形和语法填空常常不给出时间词,此时靠上下文判断:讲过去发生的事,通篇用一般过去时,别被个别句子带偏。
Last summer I volunteered at a nursing home. Every morning I helped the elderly with exercise, and they treated me like family.(去年夏天我在养老院做志愿者。每天早上我陪老人锻炼,他们待我像家人一样。)
技巧:找到一个确定的过去时间点,同一段叙述都跟着走过去时。
三、高考风格演练(4 题)
1. If he ______ (not come) tomorrow, the meeting will be put off.
答案:doesn't come 解析:时间/条件状语从句中"主将从现",从句用一般现在时,he 是第三人称单数,否定借助 doesn't。
2. Look at the clouds! It ______ rain this afternoon. A. will B. is going to C. rains D. is raining
答案:B 解析:乌云密布是"明显迹象",用 be going to 表"看迹象就要发生";will 多用于临时决定或主观预测。
3. — When shall we set off? — The train ______ at 9:15 tomorrow morning, so let's leave home at 8:00. A. left B. will leave C. leaves D. has left
答案:C 解析:火车按时刻表发车,属于"时刻表将来",用一般现在时 leaves。
4. 语法填空:Last night, when I walked past the classroom, I noticed that the lights were still on, so I went in and ______ (turn) them off.
答案:turned 解析:全段叙述昨晚的事,and 连接的并列谓语 went in 和空格处动作一致,都用一般过去时。
四、随堂练习(5 题)
1. Listen! Someone ______ (knock) at the door.
2. I ______ (visit) my grandparents this weekend — the tickets are already booked.
3. As soon as he ______ (arrive) in Beijing, he will call me.
4. — Where is Tom? — He ______ (help) the new students with registration over there.
5. 短文改错:I will tell him the news as soon as he will come back.
参考答案
- is knocking
。Listen! 提示此刻正在进行,用现在进行时。 - am visiting
。票已订好 = 安排已定,位移动词类安排可用现在进行时表将来。 - arrives
。as soon as 引导时间状语从句,主将从现。 - is helping
。问"现在在哪儿",答"正在帮忙",用现在进行时。 - will come → comes
。as soon as 从句主将从现,will 多余。
五、一句话总结
时态两把尺子:先找时间标志,再看语境视角。
- 主将从现
:if / when / as soon as 从句里,将来用一般现在时表达。 - 时刻表用一般现在,人安排用进行时,有迹象用 be going to,临时决定用 will。
- just now 是刚才(过去),right now 是此刻(进行);客观真理永远是现在时。
下期预告: 时态(二)——现在完成、过去完成、将来完成。"我已经做完作业"和"我做完作业了才去打球",两个"完成"差在哪?下期把完成时家族一次讲清。
如果这篇帮你把"两把尺子"立起来了,收藏起来,做题前先扫一遍第二节;身边还在凭感觉选时态的同学,转给他。
