Day and night 180 miners worked underground there, more than 6,00 feet 1 .They all took their 2 of night work, but Bill always worked at night. he said he 3 it.

It was a 7 getting up-because he could still see the blue light in front of his eyes. As the evening 8 darker, the light grew stronger. Bill got ready for the night shift.

7 (15分)“10米折返跑”的成绩反映了人体的灵敏素质。测定时，在平直跑道上，受试者以站立式起跑姿势站在起点终点线前，当听到“跑”的口令后，全力跑向正前方10米处的折返线，测试员同时开始计时。受试者到达折返线处时，用手触摸折返线处的物体（如木箱），再转身跑向起点终点线，当胸部到达起点终点线的垂直面时，测试员停表，所用时间即为“10米折返跑”的成绩。设受试者起跑的加速度为4m/s 2，运动过程中的最大速度为4m/s，快到达折返线处时需减速到零，减速的加速度为8m/s 2，返回时达到最大速度后不需减速，保持最大速度冲线。求该受试者“10米折返跑”的成绩为多少秒？（臂长忽略）

9 完形填空。 My husband and I insisted that our children were old enough to clean their rooms and make their beds. But they thought 1 . My complaints, even self-justified(自有道理) 2 , were always landing on 3 ears. Very often a whole hour"s scolding would end with their 4 into tears. I felt very frustrated. I realized I needed to 5 my method of "mothering". One day when they were at school, I spent some time tidying their rooms. On their desks, in plain 6 , I left the cards: "Dear Bill(the other card was 7 to Sarah), your room was messy this morning and I"m sure you like it clean. Love, the Room Fairy." 8 arriving back, the children were 9 excited to receive the little note from the Room Fairy. The next day, their rooms were fairly tidy. Sure enough, there was another note from the Room Fairy 10 for them, thanking them for their nice "gift" of a clean room and 11 asking them to play a certain violin 12 . Each day, thank-you notes would be written differently to keep the ideas 13 . Sometimes the Room Fairy would propose a little 14 : "If you can finish your homework and go over your lessons before dinner, I"d like to watch a particular television program with you tonight." Sometimes some colored markers or other little items would be left in 15 of well-done jobs the day 16 17 I can"t remember how long "the Room Fairy" continued leaving her love notes. When they were age appropriate, we used various versions of Post-Its (贴条). The bathroom mirror became the 18 centre of our home. Appointments, notices about visiting relatives, lesson schedules, and changes in plans could be 19 . all benefited from and 20 the idea of sharing reminders and daily details of life through notes. I believe the true advantage of the Room Fairy notes survives in our frequent and enjoyable communication. ( ) 1. A. different ( ) 2. A. crying ( ) 3. A. side ( ) 4. A. crying ( ) 5. A. adjust ( ) 6.
