题目内容 （请给出正确答案）

I was very disappointed not to be able to go to the jazz concert last Friday. The advertisement in the paper said that you could buy tickets at the theatre box in Richland Hills any day between 10:00 and 4:00. Since I work from 9:00 to 5:30, the only time I could go to the theatre was during my 45-minute lunch break. Unfortunately, the theatre is on the other side of the town, and the bus service between my office and Richland Hills is not very good. But if you are lucky you can make the round trip in 45 minutes. Last Monday, I stood at the bus stop for fifteen minutes waiting for the bus. By the time I saw one come around the comer, there was not enough time left to make the trip. So I gave up and went back to the office. The same thing happened on Tuesday, and again the next day. On Thursday, my luck changed. I got on a bus right away and arrived at the theatre in exactly twenty minutes. When I got there, however, I found a long line of people at the box office. I heard one man say he had been waiting in line for over an hour. Realizing I would not have enough time to wait in line, I caught the next bus and headed back across the town. By Friday I realized my only hope was to make the trip by taxi, it was expensive, but I felt it would be worth it to hear the concert. The trip by taxi only took 10 minutes, but it felt like an hour to me. When I got to the theatre, I was relieved to see that nobody was waiting in line. The reason, however, I quickly discovered, was that they had already sold all the tickets.

1、The man learned ( ) that there would be a concert last Friday.

A、 from his friends

B、form. one of his workmates

C、over the radio

D、from the newspaper

2、He tried to go to the theatre every day but managed to get there only ( ).

A、once

B、 twice

C、 three times

D、 four times

3、One day the man took ( ) to get to the theatre by bus.

A、forty-five minutes

B、 fifteen minutes

C、 just twenty minutes

D、 over an hour

4、The underlined word "relieved" may best be replaced by "( )".

A、surprised

B、please

C、puzzled

D、sorry

5、The story is mainly about ( ).

A、a good concert

B、 the bad bus service in this city

C、the difficulty of getting a ticket for a concert in a city

D、someone''s disappointment at missing a concert

考题 阅读下列说明和C代码，回答问题 1 至问题 3，将解答写在答题纸的对应栏内。 【说明】 假币问题：有n枚硬币，其中有一枚是假币，己知假币的重量较轻。现只有一个天平，要求用尽量少的比较次数找出这枚假币。 【分析问题】 将n枚硬币分成相等的两部分: (1)当n为偶数时，将前后两部分，即 1...n/2和n/2+1...0，放在天平的两端，较轻的一端里有假币，继续在较轻的这部分硬币中用同样的方法找出假币: (2)当n为奇数时，将前后两部分，即1..(n -1)/2和(n+1)/2+1...0，放在天平的两端，较轻的一端里有假币，继续在较轻的这部分硬币中用同样的方法找出假币；若两端重量相等，则中间的硬币，即第 (n+1)/2枚硬币是假币。 【C代码】 下面是算法的C语言实现，其中: coins[]： 硬币数组 first，last：当前考虑的硬币数组中的第一个和最后一个下标 include stdio.h int getCounterfeitCoin(int coins[]， int first，int last) { int firstSum = 0，lastSum = 0; int ; If(first==last-1){ /*只剩两枚硬币*/ if(coins[first] coins[last]) return first; return last; } if((last - first + 1) % 2 ==0){ /*偶数枚硬币*/ for(i = first;i ( 1 );i++){ firstSum+= coins[i]; } for(i=first + (last-first) / 2 + 1;i last +1;i++){ lastSum += coins[i]; } if( 2 ){ Return getCounterfeitCoin(coins,first,first+(last-first)/2;) }else{ Return getCounterfeitCoin(coins,first+(last-first)/2+1,last;) } } else{ /*奇数枚硬币*/ For(i=first;ifirst+(last-first)/2;i++){ firstSum+=coins[i]; } For(i=first+(last-first)/2+1;ilast+1;i++){ lastSum+=coins[i]; } If(firstSumlastSum){ return getCounterfeitCoin(coins,first,first+(last-first)/2-1); }else if(firstSumlastSum){ return getCounterfeitCoin(coins,first+(last-first)/2-1,last); }else{ Return( 3 ) } } }【问题一】 根据题干说明，填充C代码中的空（1）-（3） 【问题二】 根据题干说明和C代码，算法采用了（ ）设计策略。 函数getCounterfeitCoin的时间复杂度为（ ）（用O表示）。 【问题三】 若输入的硬币数为30，则最少的比较次数为（ ），最多的比较次数为（ ）。
