2、trunk n.行李箱行李箱 confident adj.有信心的有信心的value n.价值价值 Grammar:本课主要是介绍used to和would的用法。used to表示过去的习惯，在本课中我们要学习的是：would是另一个用于描述过去经常性行为的词，它与used to有时可以互换，有时则不可以，看 下面例子1.当我们暗示或强调今昔对比的时候，只能用used to，而不能用would。也就是说如果我们要表达过去的习惯性行为时，used to在任何情况下都可以使用。但如果我们要使用would，就要确保句意没有暗示或是强调今昔对比。I used to drink heavily,but

3、 I have given up drinking now.我过去喝酒很厉害，但我已经戒了。【明显的在做今昔对比，所以只能用used to，不能用would。】2.一个故事开头时不用would，必须首先用一段过去时或used to描述背景，然后用would表示习惯性动作。3.would不能用来描述过去的状态和情况，would只表示过去特有的习惯或行为。1.Dreams of finding lost treasure almost came true recently.最近，找到失踪宝藏的梦想差最近，找到失踪宝藏的梦想差一点儿变成现实。一点儿变成现实。(1)come true为固定短语，表为固

6、海盗们过去常把金子埋藏在那个洞里，可后来却没能取走。（1）would在这里不表示过去将来时，而表示过去的习惯性动作，它后面跟动词原形（bury和fail）。（cf本课语法）（2）fail to do sth.表示“未能”、“不能”做某事：Doctors failed to save the girls life.fail 也可用来表示没有通过某项考试：5.Armed with the new machine,a search party went into the cave hoping to find buried treasure.一支用这种新机器装备起来的探宝队进入了这个岩洞，希望找到埋

7、藏着的金子。arm(ed)with可以表示“带着”、“装着”、“穿着”等：Dont worry.Im armed with an umbrella.Youd better arm yourself with a warm coat.6.The leader of the party was examining the soil near the entrance to the cave when the machine showed that there was gold under the ground.当这个队的队长正在检查洞口附近的土壤时，那台机器显示出它的下面埋有金子。entrance

18、nd buried treasure 可以推测只有 a.gold 是探宝队所寻找的东西。b.gold mine(金矿)；c.pirates(海盗)；1.d.a tin trunk(一个铁皮箱)这3个选择都与课文的实际内 容不符，所以选a.2.a 根据课文最后一句In spite of this,many people are confident that The revealer may reveal something of value fairly soon 可以判断只有a.works very well能够说明“探宝器的性能如何,而其他3个选择都与课文内容不符合.3.b 只有b.dete

19、cting(探测)最符合语法，因为介词for 后面只能跟名词或者动名词，其他3个选择都不能用在介词后面，所以选b.4.d 前半句中的used to 表示过去常做某事，而现在已经不做了，只有d.thats what hey would do(那就是他们过去经常做的)同前半句意思想吻合。因为would 同used to 一样也可以表示过去经常性的动作。其他3个选择都表示现在还在做，不合乎逻辑。5.a 只有a.would find 是对的，因为前一句They hoped to find.就等于They hoped they would find.。其他3个选择都与前一句的时态不符合，所以选a.6.a

20、 该句是一般过去时疑问句，因为它已经有助动词did 提问了，所以谓语动词要用原形。只有a.dig 是动词原形，其他3个选择都不是动词原形，所以选a.7.c 本句的疑问词How 是对主语the hole 的状态或性质提问的,因此它后面要跟形容词.只有c.deep是形容词,表示深的,可以修饰名词hole.其他3个选择 a.deeply(深深地)词性不对;b.depth(深)是名词,词性也不对;d.down(向下)词性和词意思都不对,所以只能选c.8.a 该句的主语Revealer(探宝器)是一种机器。a.machine(机器)；b.engine(发动机，火车的机车)；c.machinery(机器总

21、称)是不可数名词；d.mechanic(技工，机修工)，这4个选择中只有a.machine 可以是Revealer 的定义，所以只能选a.9.b 前一句的examining the soil 意思是检查土壤本句需要选出一个同它含义相同的词语.a.testing it(考验它),b.looking at it carefully(仔细观察它),c.watching it(留意它),d.trying it(尝试它)4个选择中只有b.同examining the soil 含义最接近,所以选b.10.d 只有d.value(价值)最符合题目意思，因为of small value(价值很小)同前一句中

22、的almost worthless(几乎没有价值)的意义相同，所以应该选d.其他3个选择中a.worthy(值得的)是形容词，词性不对；b.honour(荣幸，荣誉)的词意思不对；c.price(价格，物价)词意思也不够贴切。11.a pletely(完全地)；b.across(横越，在对面)；c.inside(在里面)；d.finally(最终)这4个词中只有pletely 同前一句中的thoroughly(彻底地)含义相同，所以应该选a.12.b a.confide(v.吐露)；b.believe(v.相信)；c.confuse(v.使弄错，混淆)；d.confess(v.坦白)4个选择中只有b.believe 同前一句中的are confident(确信的，自信的)含义相符，所以选b.Bye bye!See you next time!
