Typically, the ice sheet begins to show evidence of thawing in late summer. This follows several weeks of higher temperatures.
Which choice most effectively combines the two sentences at the underlined portion?
A) summer, following
B) summer, and this thawing follows
C) summer, and such thawing follows
D) summer and this evidence follows
答案：A
答案解析：这是一道很典型的句子合并题，正确答案选A。分析句子不难发现，题目中的主
干句是the ice sheet begins to show evidence of thawing in late summer，A选项中，
直接在主句后使用现在分词短语following several weeks of higher temperatures，在这样的结构中，分词短语与主句之间用逗号隔开，此时分词短语在全句中起状语作用，相当于
是一个修饰的成分，因此A选项结构最为简洁，相当于简单句。根据简洁原则，语法中的简
单句>复合句>并列句，而B C D三个选项中的结构均为and连接两个完整句，属于并列句，
因此A选项具有选择优先性

This exhibit showcases sixty-eight miniature rooms inserted into a wall at eye level. Each furnished room consists of three walls; the fourth wall is a glass pane through which museumgoers observe. The rooms and their furnishings were painstakingly created to scale at 1/12th their actual size, so that one inch in the exhibit correlates with one foot in real life. A couch, for example, is seven inches long, and that is based on a seven-foot-long couch. Each room represents a distinctive style of European, American, or Asian interior design from the thirteenth to twentieth centuries.
The plainer rooms are more sparsely furnished. Their architectural features, furnishings, and decorations are just as true to the periods they represent. One of my favorite rooms in the whole exhibit, in fact, is an 1885 summer kitchen. The room is simple but spacious, with a small sink and counter along one wall, a cast-iron wood stove and some hanging pots and pans against another wall, and a small table under a window of the third wall. Aside from a few simple wooden chairs placed near the edges of the room, the floor is open and obviously well worn.
Which choice most effectively combines the sentences at the underlined portion?
A) furnished by their
B) furnished, but their
C) furnished: their
D) furnished, whereas
答案：B
答案解析：与例一不同，这道句法题主要考察的是逻辑关联。划线部分的两个句子都是有着
完整主谓结构的句子了，所以我们要选的是合适的连词来进行连接。这类题目在分析时务必
要结合上下文的大意，在理解的基础上进行选择。根据原文，本句的意思应该是“虽然越朴
素的房间越装修简陋，但是他们的装修风格，家具以及装饰品都完全忠于他们所代表的时
代”。
然后分析选项：
A选项中，by是一个介词，后面只能接短语不能接句子，所以排除;
C选项中冒号是解释说明的作用，用在这里与原文表意不符，排除;
D选项中使用了连词whereas，虽然也有表转折的作用，但是少加了代词their会使句子表意
不清，另外，whereas更多的用于对比和比较，比如 You treat the matter lightly, whereas
I myself was never more serious. 你掉以轻心，而我从来没有比这更严重。表示两种情况
的对比。
因此，这道题选B。

Artificial light sources are also costly aside from lowering worker productivity. They typically constitute anywhere from 25 to 50 percent of a building’s energy use. When a plant in Seattle, Washington, was redesigned for more natural light, the company was able to enjoy annual electricity cost reductions of $500,000
In context, which choice best combines the underlined sentences?
A) Aside from lowering worker productivity, artificial light sources are also costly, typically constituting anywhere from 25 to 50 percent of a building’s energy use.
B) The cost of artificial light sources, aside from lowering worker productivity, typically constitutes anywhere from 25 to 50 percent of a building’s energy use.
C) Typically constituting 25 to 50 percent of a building’s energy use, artificial light sources lower worker productivity and are costly.
D) Artificial lights, which lower worker productivity and are costly, typically constitute anywhere from 25 to 50 percent of a building’s energy use.
答案: A
答案解析：本题依然是一道句法题。根据前后文不难看出，原句想表达的是人工光源的缺点，
除了会降低员工生产力之外还很贵。
A选项中使用了分词短语做状语的结构，有效合并了两个句子，使原句结构最简洁;
B选项中主语被偷换为the cost of artificial light sources，改变了句意;
C选项中的表达是英文中不常用的表达方式，用and连接lower worker productivity 和
costly没有直接用介词短语Aside from lowering worker productivity简洁;
D选项中是一个复合句，根据简洁原则，不是最优选项。
