问题: 一道中考模拟题,

Thrifty Corn : 96 ¢, 12 ounces
BEST CORN : 56 ¢, 8 ounces
以上是两种罐头
1 .If you had a store coupon for 24 cent off the can of Thrifty Corn .How much would the can cost ?前一句话是什么意思?

2.Is that cost lower than Best Corn without a store coupon ?
A .Yes B .No
选哪个?这句话是什么意思?
3。Here is a ticket for twins ,so ___of them has to be left .我觉得应该填either, 而答案是one ,答案对吗?为什么?
谢谢!

解答:

1. 如果你有一张可抵折24美分的Thrifty Corn优惠券,该罐头要花多少钱?

coupon:优惠券
24 cents off:抵折24美分

2. 这笔开销比没有优惠券的Best Corn的罐头要低吗?
选A
因为Thrifty Corn每盎司的价格为(96-24)/12=6
Best Corn每盎司的价格为56/8=7

3. 答案是对的,因为如果用either of them的话,动词应该用复数形式,也就是either of them have to be left.
它不同于either...or...结构,这一结构要用单数,例如:either Rose or Mary has to be left.
