1.选C.
答案A错误之处在于rise一般作不及物动词。做及物动词时一般是使上升，使升高，使飞起或者是，使出现〔通过向其靠近而使（海上远距离物体）出现在地平线之上而被看见〕，显然不适合这句
improve一般用于提高、改进质量以使之更加完善，与作动词的perfect意思相近。显然不适合该句。
raise一般表示提升高度、强度、也可以表示数量等，当strength表示强度时，一般用raise，如Technical measure to raise the strength of cement clinker
increase系指“形状、大小、数量、程度等的增大”,如:increase one's weight [power, debt] 。
increase表示数量是可与raise 通用,比如：提高房租(to increase the rent)，提高價格(to increase the price)，提高稅金(to raise/increase the tax)，提高工資(to raise wages/salaries，to increase the pay
可当strenght指身体的，精神的或道德上的坚强力量或活力时一般用increase.如：
The discussion centred on how to increase our strength.
讨论集中在如何增强我们的力量。
loose fat and increase strength。
在the player has done _more exercise to increase __ his strength中strength作力量讲
2.选C.brought in ，bring in是引进的意思。
答数A.brought为带来， 答案B.brought up抚养，答数D.brought at不知为何怪物。
3.选B.came into
一眼就知道A.came out不正确，因为意思完全反了。
答数C.brought in用法有误，如果正确的写法是were brought in(即应该用被动语态)
答案D.brought out 不但意思完全反了，也犯与brought in一样的错误。
