新概念第二册练习册上的题目13课~·
Next month a famous group os singers,"the Greenwood Boys",will be playing at our local concert hall.All the young people in the town want to hear them and there is a great demand for tickets.People （2 are booking/booked）their seats in advance (3 in case/because) they (4 could not/want to)get tickets .Some people (5 will be trying/are trying)to (6 do/make) money on the tickets they hanve (7 bought/brought) and (8 were/are) advertising them in the paper for (9 three or even four times/half)the (10 purchase money/money they sold them for).

are booking/because/want to/ are trying/make/bought/are/three or four times/purchase money/need/need
主要解释一下第二题——为什么选are booking？事先预定不是应该选booked吗？还有12题为什么是need?还有第五行是第六个字是have不是hanve
第三题的答案是because~第四题的答案是want to

Answer 1

下个月,一个名叫“绿木男孩'的著名乐队将在我们当地的音乐厅进行表演.我们镇上所有的年轻人都想去听他们唱歌.门票的需求量很大.很多人都提前预定了他们的位置,以防拿不到票.一些人想要尝试着利用他们买的票来赚钱.他们在报纸上刊登这些票的广告,以三到四倍买价的价格来出售.
你一定需要有个好嗓子才能当一个著名歌手么?我不敢肯定,但是你必须得有个大嗓门.
这个题目主要考察的是用现在进行时来表示将来时态
第二题,are booking用现在进行时表将来,带有意图,安排,打算的含义
3.in case,以防万一
4.could not,不能
5.are trying ,同2,表意图,想通过已经买的票赚钱
6.make money,固定搭配,赚钱
7.bought,买
8.are,同2,表将来
9.three or even four times,句意 4倍
10,purchase money,句意,买价
11.need,需要一个好嗓子
12.need,因为11题选need,所以12选need,都表需要,不用want,需要一个大嗓门
want是have a desire for sth.而need 是you can not do sth without sth,虽然中文都是需要,意思不一样
补上：书上的答案没有错!
个人觉得两个都可以吧,就是你选了because后面就只能选want to,选了in case 就只能选could not,刚开始我就选的because和want to,后来发现in case 和could not 貌似也说得通的说,即：
如果是选because和want to 就是 “因为想弄到票,所以他们都提前预定了座位”
如果是选in case和could not 就是“他们提前预定座位,以防他们不能弄到票”
哦,后来想了下,要是用in case 的话后面应该是用can not,而不是 could not
