外研Join In版五年级上册 Unit 3 The ends of the earth 语法易错+巩固练习 语法易错01 will + 动词原形（一般将来时） 【语法点拨】 will 是情态动词，后接动词原形，表示将来会发生的事情或预测，没有人称和数的变化： You will see icebergs. 你们将会看到冰山。 I’ll show you my TV. 我会给你看我的电视。（I’ll = I will） Will she come back next year? 她明年会回来吗？ 否定式：在 will 后加 not，缩写为 won’t：It won’t be cold tomorrow. 明天不会冷。 疑问式：将 will 提到主语前：Will you go with me? —Yes, I will. / No, I won’t. 【易错提示】 ① will 后不能加 -s/-ing，始终用动词原形： He will goes. ✗ → He will go. ✓ ② 简略回答中，肯定用 I will，不能缩写为 I’ll：Yes, I will. ✓ / Yes, I’ll. ✗ 知识演练01 一、用括号内所给词的适当形式填空 1.

He will ________ the Arctic one day. A. visit B. visits C. visiting 6. —Will you go with me? —Yes, ________. A. I will B. I’ll C.

It’s going to melt.（根据迹象判断即将发生） will：表示预测/承诺将来会发生的事，或临时决定： You will see the Northern Lights.（预测） I’ll show you my TV.（临时决定） 课文中两种用法都出现了：We’re going to the playground.（计划） I’ll show you my TV.（临时决定） 【易错提示】 ① 已经计划好的事用 be going to，临时决定或预测用 will。不要混用！ ② 两者后面都接动词原形，但结构不同：be going to + 动词原形 vs. will + 动词原形。 知识演练02 一、用 be going to 或 will 填空 1.
