25、rightly.1.c 根据课文第二行 they have been trying to find out how the fire began 可以判断出只有c.wanted to find out what had caused the fire 最能说明消防队员仔细查看地面的原因，其他3个选择都不够全面。2.d 根据课文第根据课文第10-12行行A bird had snatched up the snake from the ground and then dropped it on to the wires When it I did so,it sent sparks down t
26、o the ground and these immediately started a fire 可以判断只有可以判断只有d.a snake which had been dropped on to the wires by a bird 与课文的实际内容相符，只有它是引起火灾与课文的实际内容相符，只有它是引起火灾的原因，其他的原因，其他3个选择都不符合课文的实际内个选择都不符合课文的实际内容。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
27、.c 本句表示时间的词是本句表示时间的词是often,表示经表示经常性的动作，因此应该用一般现在时。常性的动作，因此应该用一般现在时。a.is causing 是进行时，是进行时，b.has caused 是完成时，是完成时，d.is caused by 是是现在时被动语态，而本句需要主动语态。现在时被动语态，而本句需要主动语态。只有只有c.causes 是一般现在时，第是一般现在时，第3人称单数形式，本句人称单数形式，本句的主语的主语Broken glass 是单数，所以是单数，所以c.最最符合语法，所以选符合语法，所以选c.5.c a.almost certain(几乎肯定几乎肯定)，b.
28、fairly certain(相当肯定相当肯定)，pletely certain(完全肯定完全肯定)，d.nearly certain(几几乎肯定乎肯定)4个选择中只有个选择中只有c.同前一句中的同前一句中的quite sure(十分确信十分确信)意义最接近，所以选意义最接近，所以选c.6.c 只有只有c.succeeded in solving it(成功解决了它成功解决了它)同前一句中的同前一句中的 was able to solve the mystery(解开了这个谜解开了这个谜)的含义相同，的含义相同，所以所以c.是正确答案。是正确答案。其他其他3个选择都与个选择都与前一句意思不符。
29、前一句意思不符。7.d 只有只有d.on是对的是对的,因为它后面的词因为它后面的词是是the ground,表示在地面上表示在地面上,只能用介词只能用介词on.其他其他3个选择都不符合题目意思个选择都不符合题目意思.The snake had been on the ground.这这条蛇在地面上。条蛇在地面上。注意本句说的是在蛇被抓起之前，它在哪注意本句说的是在蛇被抓起之前，它在哪？它在地面上。？它在地面上。8.c a.controlled it(控制了它控制了它)；b.checked it(制止了它制止了它);c.extinguished it(扑灭了它扑灭了它)；d.turned it
30、off(关掉，关关掉，关上它上它)，只有，只有c.extinguished it 与前面与前面一句中的一句中的 put out the fire(把火扑灭把火扑灭)意义相同，所以意义相同，所以选选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.chancily(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!Se!
