第4题：

Building a house costs quite a lot of money. Suppose you plan to build a house. Your first step will be to find a right piece of land. Your choice will depend on many different things. You will probably try to find a sunny place, with pleasant surroundings near shops and bus stops, not too far from your friends and the place where you work.
Next you will find a good builder, and together with the builder you will work out a plan. The builder will draw the plan. It will show the number of rooms, their position and size, and other parts, which must be noticed, such as windows, doors, and electric outlets. The builder will work out how much money is needed to build your house. He will work out the cost of the wood, bricks, the glass, and everything else that must be used in building the house. Later on, when he starts to build, this estimate must be corrected and revised. His estimate is based on existing prices, but prices of such things may change, and many other things may happen between the time when he makes the estimate and the time when he builds the house.
When the builder gives his estimate, you may wish to change your plan. (You may also wish to change your builder, if his estimate is too high! ) You may find that the house you wanted at first costs too much, or that you can spend a little more and add something to your plan. The builder's estimate depends on the plan, but the final plan depends on the builder's estimate.
When the builder starts to build a house, his estimate will have to be corrected and revised because _______.

A.it is wrongly worked out by a workman
B.the future owner of the house thinks the estimate is so high that he cannot afford the building
C.the prices of building materials and the expenses of labor may be different from the original prices and expenses
D.estimates are usually mistaken in the beginning

答案：C

解析：

本题属细节考查题。考查的是在盖房的施工中，最初的预算必须更正与修改的原因。短文第二段的倒数一、二句就有相对应的部分；随后，当他开始施工时，此预算必须更改与修正。他的预算的根据是当时的价格，而建筑材料与其他东西的价格在制定预算和开始施工这一阶段很可能会有变化。A项说的是“预算经常被施工者算错”，在短文中找不到依据；B项的“未来的房主认为预算太高他支付不起”在短文中也没有体现，D项的“在开始时预算往往是错的”与A项的错误一致．

21.

答案：C

解析：文章主要围绕建房子的顺序步骤：选土地、找建筑师、做预算等来展开的，故“Planning a House”符合题意。A、B两项概括不全面，只是文章内容的一部分。

22.

答案：B

解析：根据文中“Your first step will be to find a right piece of land.”可知，建房子的第一件事是要找到一块合适的土地。故选B。

23.

答案：A

解析：根据“draw a plan”后面的“It will show the number of rooms, their position and size, and other parts, which must be noticed, such as windows, doors, and electric outlets.”可知，建筑师绘制的平面图具体包括房间的数量、位置、尺寸以及窗户、门、电插座等。故A项符合题意。

24.

答案：C

解析：根据文中“His estimate is based on existing prices, but prices of such things may change, and many other things may happen between the time when he makes the estimate and the time when he builds the house.”可知，预算是建立在现有价格上的，但是这些价格可能会变，而且在建筑师作出预算和建造房子之间可能会发生许多其他事情，故C项正确。

The phrase "draw a plan" in this passage means _______

A.making a picture of a building or a room
B.making a plan
C.working out a plan
D.pulling a picture out of a room

答案：A

解析：

解答该小题的重点是要准确理解“draw a plan”这个短语中的关键词plan。plan在本短文中反复出现了八次，第一次出现以动词形式出现，其他七次都是名词。作名词用时其常见用法有二：计划，方案；平面图，纸张。plan在与draw连用时，就表明：画一张建筑物的平面图。B项和C项都是把plan理解为“计划”或“方案”了，而D项则理解成“把一张图画从屋里找出来”，这是无稽之谈。由此答案非A莫属。

第10题：

A.Building a House Costs Much Money
B.Estimate Is Important
C.Planning a House
D.Depend on the Builder

答案：C

解析：

本题考查对整篇短文中心思想的理解。A项讲的是“盖一幢房子要花很多钱”，这是本文的第一句话，但它只讲了上述三段的盖房子要花很多钱这一项内容，所以其概括不准确。B项是说“预算是重要的”．同样犯了以偏概全的毛病。D项讲的是“依靠建筑工”，这与短文内容是相矛盾的．故此三者皆否定之。

You are running parallel to the coast and estimate that the
