考前问几道prep题 Prep-24，prep-25

红色部分为正确答案

24.        (25819-!-item-!-188;#058&002130)

Employment costs
rose 2.8 percent in the 12 months that ended in September, slightly less
than they did in the year that ended in the previous quarter.

(A) less than they did

(B) less than it did

(C) less than they
were

(D) lower than

(E) lower than they
were

 我想问问low 和 less 的区别是什么？这里指的是程度上的比较还是绝对值上的比较？

是不是涉及到增长，就值得是程度上的比较？

25.        (25865-!-item-!-188;#058&002136)

Often incorrectly
referred to as a tidal wave, a tsunami, a seismic sea wave that can reach up
to 150 miles per hour in speed and 200 feet high, is caused by underwater
earthquakes or volcanic eruptions.

(A) up to 150 miles per hour in speed and 200 feet high,
is

(B) up to 150 miles
per hour in speed and heights of up to 200 feet, is

(C) speeds of up to
150 miles per hour and 200 feet high, are

(D) speeds of up to 150 miles per hour and heights of up to
200 feet, is

(E) speeds of up to
150 miles per hour and as high as 200 feet, are

我理解D非常平行，但不明白为什么要用复数？是说它的速度和高度在某一个范围里？就是speed在0-150之间都有可能？
