标题: [求助]GWD24-22

Most household appliances use electricity only when in use. Many microwave ovens,
However, have built-in clocks and so use some electricity even when they are not in
Use. The clocks each consume about 45 kilowatt-hours per year. Therefore, house
Holds whose microwave oven has no built-in clock use 45 kilowatt-hours per year
Less. On average, than do comparable households shoes microwave oven is other-
Wise similar but has a built-in clock.

Which of the following is an assumption on which the argument depends?
A Households that do not have a microwave oven use less energy per year, on
average, than do households that have a microwave oven.
B Microwave ovens with a built-in clock do not generally cost more to buy than
microwave ovens without a built-in clock.
C All households that have a microwave oven also have either a gas oven or a
Conventional electric oven.
D Households whose microwave oven does not have a built-in clock are no more
likely to have a separate electric clock plugged in than households whose
microwave oven has one.
E There are more households that have a microwave oven with a built-in clock
than there are households that have a microwave oven without a built-in clock.
Answer:

毫无头绪,请大家指教,最N的是我觉得这题好像没结论,请高手指教

还有,最后一句的shoes哪来的,搞得我好晕

不是高手…..只是新手来挑战..

这道D??

我觉得D只是文章全部改写的浓缩版

D: 相较于本来有built-in clock, 没有built-in clock微波炉的家庭,也不可能会再放一个要另外要接电的clock
                    

因为第一句说许多家电用品用电是当他们使用时。
                    


D就是假设前提啰!
                    

因为本来就没built-in clock了!表示当初就认为没有使用的必要,于是也不会想再用外接的clock,而刚好符合题目的first sentence 其它后面,都只是要影响思考的废话。

 

A Households that do not have a microwave oven use less energy per year, on average, than do households that have a microwave oven.->非文章讨论范围
B Microwave ovens with a built-in clock do not generally cost more to buy than microwave ovens without a built-in clock.->明显与文章论述相反
C All households that have a microwave oven also have either a gas oven or a Conventional electric oven.->IR
D Households whose microwave oven does not have a built-in clock are no more likely to have a separate electric clock plugged in than households whose microwave oven has one.
E There are more households that have a microwave oven with a built-in clock than there are households that have a microwave oven without a built-in clock.->比较microwave oven with a built-in clockwithout a built-in clock拥有人数多寡NONSENSE

 

请指教

谢谢lily同学,想通了Therefore, house
Holds whose microwave oven has no built-in clock use 45 kilowatt-hours per year
Less. On average, than do comparable households shoes microwave oven is other-
Wise similar but has a built-in clock.两句连起来是结论

我走错房间了,这题题号仿佛是24-18呀。

既然进来了顺便说一句,这题打字水平实在够呛啊!结论貌似是

Therefore, households whose microwave oven has no built-in clock use 45 kilowatt-hours per year less, on average, than do comparable households whose microwave oven is otherwise similar but has a built-in clock.

lily的选项跟我一样,但解释跟我有点不一样,我觉得D的意思是

微波炉里没有钟的家庭不会比有钟的家庭多买一个钟。

也就是说如果一般微波炉里没有钟的家庭如果还要另外多用一个钟,那么其家庭费电量与微波炉有钟的家庭不会还是一年差45度了(至少差距缩小)

另外个人觉得相对比较有迷惑性的选项是B:说内置钟的微波炉购买的成本不比无钟的微波炉高。这个结论貌似拉大了两种家庭的成本差,但是看结论的问法仅仅是问耗电量比较,没有提其他经济成本,所以这个选项超出结论讨论范围了。
