本题考查将含感官动词或形式宾语的简单句转换为that引导的宾语从句，需遵循时态一致原则，并保证从句为完整的陈述句结构：
1. 原句为一般过去时，notice后的宾语从句时态保持一致，需将原句中的动词原形leave改为过去式left，从句为“Mary left the party early yesterday”；
2. saw为一般过去时，从句中动词fly需变为过去式flew，从句为“two planes flew over her home just now”；
3. 原句中it为形式宾语，转换为that从句时，用it作从句的形式主语，不定式为真正主语，从句为“it is uncomfortable to go to school by bus”；
4. 原句中it为形式宾语，转换为that从句时，用it作从句的形式主语，不定式为真正主语，从句为“it is easy to repair this bicycle”，保持原句的否定含义；
5. 原句是hear sb doing sth（听到某人正在做某事），转换为宾语从句需用过去进行时，从句为“his neighbour was playing the piano this morning”；
6. 原句中it为形式宾语，转换为that从句时，用it作从句的形式主语，不定式为真正主语，从句为“it is necessary to go jogging every day”。
