1.ds 一个仓库里储藏某东东，本来是12个东东装一箱，正好装完没剩余，后来加了60个这种东东，变成14个一箱，正好装完没剩余。问本来有多少东东
                

     应该是加东东，而不是加箱子吧

可爱的小猪sisi啊！有了老公就不自由了，再没有机会了，你可是机会多多啊！

讨论一道题吧

Nitrogen dioxide is a pollutant emitted by automobiles.  Catalytic converters, devices designed to reduce nitrogen dioxide emissions, have been required in all new cars in Donia since 1993, and as a result, nitrogen dioxide emissions have been significantly reduced throughout most of the country.  Yet although the proportion of new cars in Donia’s capital city has always been comparatively high, nitrogen dioxide emissions there have showed only an insignificant decline since 1993.

Which of the following, if true, most helps to explain the insignificant decline in nitrogen dioxide emissions in Donia’s capital city?

1. More of the cars in Donia’s capital city were made before 1993 than after 1993.
2. The number of new cars sold per year in Donia has declined slightly since 1993.
3. Pollutants other than nitrogen dioxide that are emitted by automobiles have also been significantly reduced in Donia since 1993.
4. Many Donians who own cars made before 1993 have had catalytic converters installed in their cars.
5. Most car trips in Donia’s capital city are too short for the catalytic converter to reach its effective working temperature.

 总是想不通E怎么能解释呢，跟温度啥么关系啊，有点晕

和温度没关系，只是说，在某种情形下，这个device 是不管用的。那么这种情况就是 这些车跑的距离太短，device还美热身起来，所以不能发挥作用。所以，这种情况使得device 不管用，恰巧就老发生在capital city 也就使得 污染没怎么减少——一句话，那个device 还是不管用啊

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.

 

(A) electricity was in less than one percent of homes, where lighting was still

(B) electricity was in less than one percent of homes and lighting still

(C) there were less than one percent of homes with electricity, where lighting was still being

(D) there was less than one percent of homes that had electricity, having lighting that was still  A

(E) less than one percent of homes had electricity, where lighting had still been

我觉得是E 啊 PUBLIC PLAXES 对 HOMES~~~

qianrene

(E) less than one percent of homes had electricity, where lighting had still been

where的修饰词不对，had been时态没道理~~

amorela

这里E也不是public places对应homes,如果按照E的说法,是public places 对应less than one percent of homes,地方对应数字.而且为什么要用过去完成式呢?应该是说lighting依然被用,是一个延续到说话时的动作,用过去的过去没道理.

而B错在: and lighting still 的结构错.

C和D there be错,there be只表示一种存在的状态.用在这里不适合.而且but 前后结构不一致. 而且C,D后面的动词也错.
