三、重点语法。
1. I’m going to do some shopping tomorrow.
2. We are going to have a party next Wednesday.
3. She is going to learn a new language next year.
4. Look at the sky! It is going to rain soon.

【分析】
be going to是一般将来时的常用结构，用于表达计划打算做某事，或根据迹象推测即将发生的事。解题时需注意三点：①主语对应正确的be动词（I配am，we配are，she/it配is）；②后接动词原形；③时间状语（如明天、下周三）放句尾，同时牢记固定短语搭配（如“去购物”do some shopping、“举行聚会”have a party）。第4句是根据天空的迹象推测下雨，需用be going to表迹象推测的用法。
【解析】
1. 主语“我”对应I，be动词用am，“去购物”是固定搭配do some shopping，时间状语“明天”为tomorrow，组合得：I’m going to do some shopping tomorrow.
2. 主语“我们”对应We，be动词用are，“举行一次聚会”是have a party，时间状语“下周三”为next Wednesday，组合得：We are going to have a party next Wednesday.
3. 主语“她”对应She，be动词用is，“学习一门新语言”是learn a new language，时间状语“明年”为next year，组合得：She is going to learn a new language next year.
4. “看这天空”译为祈使句Look at the sky! 天气用it指代，be动词用is，“马上要下雨”是It is going to rain soon，组合得：Look at the sky! It is going to rain soon.
【答案】
1. I’m going to do some shopping tomorrow.
2. We are going to have a party next Wednesday.
3. She is going to learn a new language next year.
4. Look at the sky! It is going to rain soon.
