第1题:

关于worth的Try to spend your time just

Try to spend your time just on the things you find _________. 

 A. worth doing them B. worth being done C. them worth doing D. worth doing


     【解析】you find worth doing是关系代词that(作find的宾语,that省略)引导的定语从句,worth doing是宾补。
答案是选择C 的。因为fine sth. doing.
而且是worth doing sth.
所以答案选择C。
应该选D。
worth doing

Try to spend your time just on the things you find

这句话是祈使句。Try to spend your time 是句子的主体。to spend是不定式宾语。your time是宾补。后面on是状语修饰time。you find worth doing 是修饰the things 的定语。things作为在定语从句中被修饰的宾语。因此后面没有them。所以AC不选。

worth是形容词。后面加doing。worth doing本身就有被动的意思。所以是值得被做的。doing是worth的补语。因此不能选B。
应该选D。
worth doing

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.
The first thing for a person to build a house is ______

A.to get as much money as possible
B.to find a suitable piece of land
C.to work out a plan
D.to make an estimate

答案:B
解析:
由短文首段的第三句“Your first stepwill betofind a right plece of land.”(你的第一步就是选好一块合适的地)可知此句正是该题答案的出处

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7题:

请阅读短文,完成此题。
What should you think about in trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong or weak subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. Knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.
Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metal work or cookery and look for a job where you can improve these skills.
If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in apart-time job. Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is bitter to face any weaknesses than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic about it but instead recognize that you will have a chance of a fresh start at work.

The writer thinks that for a student to have a part-time job is probably__________.
查看材料

A.a waste of time that could have been spent on study
B.useful for his future work
C.a good way to earn extra money
D.a good way to find out his weak points

答案:B
解析:
本文的第三段说的是兼职工作能教给人哪些素质,以及它能让人认识到自己对什么职业感兴趣。因此B项最合适。

Next you will find a good builder, and together with the builder you will work out a plan. The builder will draw the plan.

The best title of this passage is ________

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。
