正确答案: 1.C 考查介词用法。in表示“在…内”;at表示“位于”;to表示“向,去”;0f表示所属关系。由于这里指的是“到英国旅游的游客”,所以选C。
2.A 考查动词辨义。say说;ask问;tell告诉;talk谈论。因为空格后是一个直接引语,且引语不是问句,所以只能选A。tell应用人作间接宾语、直接引语作直接宾语;talk为不及物动词。
3.C 考查形容词辨义与上下文理解。由空格前两个并列句与常识可知,填人的形容词应与not good同义,故选含否定义的terrible(糟糕的),wonderful精彩的,极妙的;nice好的,优雅的;special特别的。
4.C 考查副词与上下文理解。由句意与常识可知,只有当人们没有机会实践时他们才会得出错误的结论,所以此处选含否定义的副词seldom(很少),always总是,一直;often常常。never(从不)虽然也是否定副词,但它过于绝对,与常识不符。
5.B 考查代词用法与上下文理解。many不与of连用;most of指“大部分”;all of指“所有”;none of指“没有一个”。很明显,C、D两项都过于绝对,根据常识即可排除。
6.B 考查名词辨义与上下文理解。visitor游客;owner拥有者,老板;waiter侍者,服务生;guest客人。由于本句中and前后是顺承关系,表达的实际上是一种较弱的因果关系,而A、C、D三项都无法必然使饭店供应外国饭菜,所以B最恰当。
7.A 考查动词辨义与上下文理解。invite邀请;make使,制造;offer提供;ask要求。游客当然是被邀请到别人家里去吃饭,所以选A。
8.C 考查形容词辨义与上下文理解。different不同的;usual通常的;常见的;foreign外国的,不熟悉的;delicious美味的。由于全文谈论的都是外国游客对英国饭菜的印象,所以这里选与这一主旨有关的 C。这一句的意思是,邀请了游客到家里来吃饭时,英国人觉得不应当让客人吃英国饭菜,而应当做一些外国饭菜,所以才让人觉得英国饭菜不好。
9.B 考查从句连接词。先行词是人,填人的连接词在从句中作主语,故选who。
10.D 考查情态动词。should表示“应当”;must表示“必须”;may表示“也许”;can表示“能够,可能”。由句意及空格后表强调的副词really可知,应当选can。
11.B 考查固定搭配与上下文关系。at the same time同时;on the other hand另一方面;for example例如;in another word换句话说。前面一句说的是对于那些了解英国饭菜的人来说,英国饭菜真的很好,而空格后说的则是对于另外一些人来说英国饭菜很糟糕,前后明显是对立的关系,故选B。
12.C 考查副词形式。some time指“一些时间”;sometime指将来或过去的“某个时候”;sometimes指“有时,间或”;some times形式不对。本题指的是一种常见的情况,不指过去或将来,故选C。
13.A 考查名词与上下文理解。前文谈论的是游客对英国饭菜的好坏有两种相互对立的印象,这无疑是一个“问题”(problem),本句即是指出这一问题的部分(原因)所在,选A。其余三项都不合本文逻辑: question(需要回答的)问题,疑问;answer答案;time时间,次数。
14.C 考查动词搭配。由空格后的time和cooking这一现在分词形式可知,应选spend,构成spend time (in) doing sth.这一固定搭配。其余三项都不能这样用。
15.C 考查形容词与上下文理解。由空格前表并列的连词and及句意可知,应选与simple属于同一范畴和词性的easy(容易的,轻松的)。
16.B 考查介词。将食物加热当然是在吃饭之前,因此选介词before。
17.D 考查介词与上下文理解。near靠近,接近;inside在…内部around围绕,在…周围;away from远离。由空格前后country(乡村)与large towns(大城镇)的相对关系可知,选D最恰当。
18.B 考查从句连接词。先行词是country(乡村),表示的是地点,而填入的词在从句中又是作状语,故选where。注意,先行词不是large towns。
19.A 考查上下文关系。前文谈论的都是游客对英国食物好坏的印象及原因,并且空格前一句说的是在哪些地方可以找到最好的英国饭菜;而空格后说的则是游客并非是为了饭菜而来英国的,两者之间存在明显的转折关系,故选but。
20.C 考查固定搭配。空格后是一个名词,因此应填人一个介词。能与because连用的介词是of,构成固定搭配because of(因为,由于)。

第2题:

莨菪碱(A)、山莨菪碱(B)、东莨菪碱(C)的碱性顺序为

A. A. >B. >C.
B. A. >C. >B.
C. B. >A. >C.
D. B. >C. >A.
E. C. >B. >A.

答案:A
解析:
东莨菪碱和樟柳碱由于6、7位氧环立体效应和诱导效应的影响,碱性较弱;莨菪碱无立体效应障碍,碱性较强;山莨菪碱分子中6位羟基的立体效应影响较东莨菪碱小,故其碱性介于莨菪碱和东莨菪碱之间。
