No wrong numbers

Mr. James Scott has a garage in Silbury and now he has just bought another garage in Pinhurst. Pinhurst is only five miles from Silbury, but Mr. Scott cannot get a telephone for his new garage, so he has just bought twelve pigeons. Yesterday, a pigeon carried the first message from Pinhurst to Silbury. The bird covered the distance in three minutes. Up to now, Mr. Scott has sent a great many requests for spare parts and other urgent messages from one garage to the other. In this way, he has begun his own private 'telephone' service.

没有错号

詹姆斯·斯科特先生在锡尔伯里有一个汽车修理厂,现在他刚在平赫斯特又买了一个。平赫斯特距离锡尔伯里只有五英里,但斯科特先生的新车库装不上电话,所以他刚买了12只鸽子。昨天,一只鸽子把第一封信从平赫斯特带到了锡尔伯里。这只鸟只用了三分钟就飞完了全程。到目前为止,斯科特先生从一个修理厂向另一个修理厂发送了大量索取备件的请求和其他紧急信件。就这样,他开始了自己的私人"电话"业务。

🔑 关键句型:一般过去时 vs 现在完成时

本课最关键的学习点:同一个故事中两种时态交替使用,理解为什么用这个而不是另一个。

课文时态分布

句子时态为什么?
Mr. Scott has a garage in Silbury. 一般现在时 事实陈述(他一直拥有)
He has just bought another garage. 🎯 现在完成时 刚完成的动作,与现在相关
Pinhurst is only five miles away. 一般现在时 客观事实(距离不会变)
Mr. Scott cannot get a telephone. 一般现在时 现在的状态(装不了电话)
He has just bought twelve pigeons. 🎯 现在完成时 刚完成的动作
Yesterday, a pigeon carried the first message. 🎯 一般过去时 具体过去时间(yesterday)
The bird covered the distance in 3 minutes. 🎯 一般过去时 过去的一个具体事件
Up to now, he has sent a great many requests. 🎯 现在完成时 到目前为止(up to now)
He has begun his own service. 🎯 现在完成时 已开始,结果影响现在

📌 核心判断法则

看到 具体过去时间(yesterday, last week, in 2020)→ 一般过去时

看到 just / already / never / up to now / ever / yet现在完成时

看到 for + 时间段 / since + 时间点现在完成时

没有时间词 → 想一下:是过去的动作(一般过去时),还是与现在的联系(现在完成时)?

⚠️ 最常犯的错误:
I have seen him yesterday.(yesterday 是具体过去时间,不能用现在完成时)
I saw him yesterday.(一般过去时)
I have seen him three times today.(today 还没结束,现在完成时)

⚡ 时态对比示例

一般过去时 ✅现在完成时 ✅
I arrived at 8 o'clock.(具体时间) I have just arrived.(刚刚到)
He bought the car last year.(去年) He has just bought a car.(刚买)
She went to Paris in 2020.(过去某年) She has been to Paris twice.(经历,不关心时间)
We lived there for five years.(现在不住了) We have lived here for five years.(现在还住)

3. arrived(yesterday → 具体时间)
4. has just finished(just → 刚刚)
5. Have ... ever eaten(经历疑问句)

  2. She has went to London. → _______________
  3. They haven't finished already. → _______________

  5. Have you ever went to Australia? → _______________
答案:
1. I saw him yesterday.(yesterday 不能用现在完成时)
2. She has gone to London.(过去分词是 gone,不是 went)
3. They haven't finished yet.(否定句用 yet 不用 already)
