24、rom the ground and then dropped it on to the wires When it I did so, it sent sparks down to the ground and these immediately started a fire 可以判断只有d. a snake which had been dropped on to the wires by a bird 与课文的实际内容相符，只有它是引起火灾的原因，其他3个选择都不符合课文的实际内容。,3. a 只有a. since最合乎题目意思和语法。因为本句是现在完成进行时，只有since引导的时间短
25、语最适合于完成进行时态，表示“自从以来”，所以应该选a.其他3个选择都不能引导合适的时间短语。,4. c 本句表示时间的词是often, 表示经常性的动作，因此应该用一般现在时。 a. is causing 是进行时，b. has caused 是完成时，d. is caused by 是现在时被动语态，而本句需要主动语态。 只有c. causes 是一般现在时，第3人称单数形式，本句的主语Broken glass 是单数，所以c.最符合语法，所以选c.,5. c a. almost certain(几乎肯定)， b. fairly certain(相当肯定)，c. completely ce
26、rtain(完全肯定)， d. nearly certain(几乎肯定)4个选择中只有c. 同前一句中的quite sure(十分确信)意义最接近，所以选c.,6. c 只有c. succeeded in solving it (成功解决了它)同前一句中的 was able to solve the mystery (解开了这个谜)的含义相同，所以c.是正确答案。 其他3个选择都与前一句意思不符。,7. d 只有d. on是对的,因为它后面的词是the ground,表示在地面上,只能用介词on.其他3个选择都不符合题目意思. The snake had been on the ground.
27、这条蛇在地面上。 注意本句说的是在蛇被抓起之前，它在哪？它在地面上。,8. c a. controlled it (控制了它)；b. checked it (制止了它); c. extinguished it (扑灭了它)；d. turned it off (关掉，关上它)，只有c. extinguished it 与前面一句中的 put out the fire (把火扑灭) 意义相同，所以选c.,9. d 只有d. this morning 今天早上, 是正确的表达方式.其它3个选择都不符合习惯用法,都不是正确的表达方式.所以选d.,10. a a. by chance (偶然)，b. c
28、hancily (没有这个词)；c. fortunately (幸运地) 和d. luckily (侥幸地，幸运地)这4个选择中只有a. by chance 同前一句中的accidentally (偶然地)意义相同，所以选a.,11. c 前一句的短语In this way 是“用这种方法“,本句需要选一个同这一短语含义相符合的短语. a. Thats so 就是如此 b. like this 像这样 d. so 因此, 这3个选择都不符合题目意思. 只有c. Thats how(那就是的方法)同In this way 的含义相符合,因为how 相当于the way in which ,所以选c.,12. c a. taken(拿), b. pulled(拉,拖), c. seized(抓住)和d. carried(携带)4个选择中只有c. seized同前一句的snatched(抓住)意义相同,所以选c.,Bye bye ! See you next time!,
