一、用 be going to 结构完成句子
1. Tom (pick) apples on the farm this Sunday.
2. There (be) a talk on education in our school tomorrow.
3. your classmates (play) computer games next Saturday?
4. I (not go) fishing this Sunday. I (have) a field trip.
5. —Are you free tomorrow?
—No. I (see) my grandma. She is ill in hospital.

1. is going to pick
2. is going to be
3. Are; going to play
4. am not going to go; am going to have
5. am going to see

【分析】
要完成这些句子，需掌握be going to结构的用法：该结构用于表达计划、打算做的事，基本构成为“主语 + am/is/are + going to + 动词原形”，其中be动词随主语的人称和数变化（I用am，第三人称单数用is，复数/第二人称用are）；否定句在be动词后加not，一般疑问句将be动词提前。另外，there be句型的将来时特殊结构为“there is/are going to be”，需根据后面的名词单复数确定be动词。解题时先确定每个句子的主语，匹配对应be动词，再结合句式调整，最后接动词原形。
【解析】
1. 主语Tom是第三人称单数，be动词用is，后接going to加动词原形pick，故填is going to pick。
2. there be句型的将来时，中心名词a talk是单数，be动词用is，结构为is going to be，故填is going to be。
3. 本句为一般疑问句，主语your classmates是复数，be动词用Are，后接going to加动词原形play，故填Are; going to play。
4. 主语是I，否定句用am not，后接going to加动词原形go；后半句主语仍为I，用am going to加动词原形have，故填am not going to go; am going to have。
5. 主语是I，be动词用am，后接going to加动词原形see，故填am going to see。
【答案】
1. is going to pick 2. is going to be 3. Are; going to play 4. am not going to go; am going to have 5. am going to see
【知识点】
be going to结构；一般将来时；主谓一致
【点评】
本题聚焦be going to这一一般将来时核心结构，覆盖不同句式（肯定、否定、疑问）及there be句型的将来形式，是初中英语语法基础巩固的典型题型，能帮助学生熟练掌握be动词与人称的匹配规则，夯实一般将来时的运用能力。
