6.B do表示强调。用在祈使句中，置于be careful之前，可理解为“务必”。

5.C　 go进展，进行；work out 结果是；try out 考验，提炼；carry on 继续开展；it 指代our art exhibition,but的转折语气说明它进展得很好，C项合句意。

3. C keep词组考查题。keep on 继续，保持；keep at 坚持做，不放弃；keep up 保持(良好状态)，坚持；keep out 关在门外，不准入内。只有C项合题意。

4 A　 涉及keep 的用法题。由于standing表示静止状态，故不可用kept standing ,又rested,left与standing 在搭配和含义上有错误，故选remained standing ,相当于过去进行时。

2.D动词consider 的非谓语考查形式。符合“consider+宾语+宾补”结构，根据句意判断此句的宾补在consider之前已经发生，故用不定式的完成式。

1. C 考查make词组搭配题。根据句意：为祖国工作，应当充分利用分分秒秒。应考虑表示“利用”的make use of ,与表示“时间”的every minute之间存在动宾关系，因此，make use of 须用被动形式。故选C。
