语法精讲
be going to
用法
表示打算、计划或决定要做某事。如：We are going to have an exam tomorrow.
表示根据目前情况所作出的推测。如：The sky is becoming dark.It’s going to rain.
句式
肯定句：主语++其他.
否定句：主语++其他.
一般疑问句：+主语+going to+动词原形+其他？
特殊疑问句：疑问词+be+主语+going to+动词原形+其他？
当there be句型与be going to连用时，意为“将有……”。其结构为“There is/are going to be...”。注意to后的系动词be不能换成have。如：下周六我们学校将有一场篮球赛。
误：There is going to have a basketball match next Saturday in our school.
正：There is going to be a basketball match next Saturday in our school.
注意
be going to后一般不接go，come，start，leave等表示位置移动的词，这类动词通常用现在进行时表示将来。如：I’m coming./We are going to Beijing for a holiday.
表示客观上必然会发生的事情时，不用be going to结构。如：
Today is Monday，and tomorrow is Tuesday.

3. 此处用现在进行时表将来，结构为“am/is/are + 现在分词”，主语是I，故填am leaving。
4. 由often可知，句子用一般现在时，主语she是第三人称单数，动词get变第三人称单数形式gets，故填gets。
5. 由Look可知，句子用现在进行时，结构为“am/is/are + 现在分词”，主语my sister是单数，故填is setting。
6. 由last week可知，第一空用一般过去时，win的过去式是won；由every day可知，第二空用一般现在时，主语she是第三人称单数，spend变spends，故填won;spends。
【答案】1. is going to be 2. Are;going to take 3. am leaving 4. gets 5. is setting 6. won;spends

【分析】本题考查一般将来时（be going to结构）的句式转换与时态改写，解题思路：1. 改一般疑问句需将句中be动词提前至句首；2. 改否定句在be动词后加not（缩写）；3. 对动作提问用What，结构为“What + be + 主语 + going to do？”；4. 同义句转换时，be going to的“有”结构对应“There is/are going to be”；5. 用将来时间改写时，将原时态转换为be going to的一般将来时。
【解析】1. 原句含be动词is，改一般疑问句将is提前，其余部分保留，故填Is; going to；2. 原句be动词为are，改否定句加not缩写为aren't，故填aren't going；3. 划线部分是动作，用What提问，主语Joan对应be动词is，结构为What is Joan going to do，故填What is; going to do；4. 原句表“举办派对”，同义转换为there be的一般将来时，即There is going to be，故填is going to be；5. next term表将来，将原现在进行时改为be going to结构，主语Linda对应is，故填is going to learn。
