5．-Tom seems not so enthusiastic as he was two years ago．
-Yes．He's really reached a point in his career ______ he has to decide what to do next．（ ）
| A． | that | B． | when | C． | where | D． | which |
试题答案
分析 -汤姆似乎没有两年前那么热情了．
-是的，他的事业真的到了必须决定下一步该做什么的关头了．
解答 答案：C
本句是定语从句；先行词是a point，由于该从句中缺少状语，指的是"at a point在某种关头"；故用关系副词where，故选C．
点评 做本题时，需要掌握定语从句的结构特点以及关系副词where的用法；
1．where 主要用于修饰表示地点的名词/代词，在定语从句中用作地点状语，
如：This is the village where he was born．这就是他出生的村子．
That's the hotel where we were staying last summer．这就是我们去年夏天住的旅馆．
2．where有时还可用于抽象名词后引导定语从句，并在该从句中作状语；
如：We have reached a point where a change is needed．我们到了必须改一改的地步．
There are cases where the word"mighty"is used as an adverb．在一些情况下，mighty一词可用作副词．
阅读下列短文，从每题所给的四个选项(A、B、C和D)中, 选出最佳选项。
According to the US government, wind farms off the Pacific coast could produce 900 gigawatts of electricity every year．Unfortunately, the water there is far too deep for even the tallest windmills to touch bottom．An experiment under way off the coast of Norway, however, could help put them anywhere．
The project, called Hywind, is the world’s first large-scale deepwater wind turbine (涡轮发电机)．Although it uses a fairly standard 152-ton, 2．3-megawatt turbine, Hywind represents totally new technology．The turbine will be fixed 213 feet above the water on a floating spar, a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently．The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables ; these will keep the spar stable and prevent the turbine from moving up and down in the waves．Hywind’s stability in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power．If all goes according to the plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September．
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean．To make that turbine heavier, the whole spar’s center of gravity must be moved much closer to the ocean’s surface．To do that, the company plans to design a new kind of wind turbine, one whose gearbox (变速箱) sits at sea level rather than behind the blades．
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large．Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted．Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection．If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available．
1.The Hywind project uses totally new technology to ensure the stability of_________.
A．the cables which tie the spar to the ocean floor
B．the spar which is floating in deep-sea water
C．the blades driven by strong and steady sea wind
D．the stones filled in the spar below the sea surface
2.To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed with its gearbox sitting_________.
A．on the sea floor
B．on the spar top
C．at sea level
D．behind the blades
3.Wide applications of deepwater wind power technology can_________.
A．solve the technical problems of deepwater windmills
B．make financial profits by producing more turbines
C．settle the arguments about environmental problems
D．explore low-carbon power resources available at sea
