拼写、标点与校对：原创混合练习与详解

“Yesterday” 指过去。“walk” 变成 walked。“meet” 是不规则动词，过去式是 met。

Yesterday, Li Wei walked to school and met his teacher.

“Three of the” 后面需要复数名词：girls。复数主语需要 bring。“their bag” 变成 bags，因为三个女孩带的不止一个包。

Three of the girls bring their bags to class.

两个词都在描述动词，所以都需要 -ly。“slow” 变成 slowly。“polite” 变成 politely（保留 e）。

The speaker talked slowly and answered every question politely.

• run：一个短元音加一个结尾辅音，所以重复：running。
• hope：去掉不发音的 e：hoping。
• plan：重复 n：planning。
• wait：结尾辅音前有两个元音，所以不重复：waiting。

两个完整的想法只用逗号连接。下面几种写法都正确：

• It was late. The shop was closed.
• It was late; the shop was closed.
• It was late, so the shop was closed.
• The shop was closed because it was late.

“However” 自己不能连接两个想法。在它前面用分号，后面用逗号：The plan was simple; however, it took weeks. 也可以用连接词：The plan was simple, but it took weeks.

缺口。 错误的写法出现了两次，而学生无法当场改正。做法：学会 “receive” 在 c 之后是 ei，用 “receive”、“received” 和 “receiving” 各写一个新句子，三到五天后重测。

• 大写：My。
• 词尾：单数的 “brother” 用 works；“he enjoy” 变成 enjoys；复数的 “customers” 用 are。
• 标点：逗号连接了两个完整的想法，所以用 “and”：works in a bank, and he enjoys。
• 拼写：because。
• 句末标点：加句号。

My brother works in a bank, and he enjoys it because the customers are friendly.

按遍数逐一处理。

词尾： “go” 变成 went（过去）。“We was” 变成 We were。“show” 变成 showed。“how he” 后面的 “milk” 变成 milked（过去）。“Everyone were” 变成 Everyone was（“everyone” 是单数）。

标点： “We were excited, the bus left at seven” 是逗号拼接。用 “and” 或句号：We were excited, and the bus left at seven.

拼写： “suprised” 变成 surprised。

改正后： Last month our class went on a trip to a farm. We were excited, and the bus left at seven. The farmer showed us how he milked the cows. Everyone was surprised by how warm the milk felt.

条目应该有完整句子形式的错误写法和正确写法、类型、学生自己话写的简短规则，以及用新句子做的重测。
