An international group of more than 2,000 scientists project an average global warming that will be between 1.8 and 6.3 degrees Fahrenheit by the year 2000.
(A) project an average global warming that will be between 1.8 and
(B) project an average global warming to be from 1.8 to
(C) project global warming that will average between 1.8 and
(D) projects global warming to average from 1.8 to
(E) projects an average global warming of between 1.8 and 答案分别是B E 第一道题目先来谈谈时态吧，从句的确是一般现在时，按照道理主句就应该是一般将来时，但根据句意，应该用虚拟语气似乎好一点啊，请问有没有从句已经用了一般现在时，主句虚拟的呢，我记得从句用一般现在，主句是时态不限制的吧，可以为现在和将来的任一个时态。另外这道题比较对象是a level吧，希望我没有弄错！
关于第二道题，问题比较大一点，首先主语肯定是单数，所以谓语动词肯定是单数了，因此从DE中选择，我选择了D，E里面的of between 两个并在一起太奇怪了，我觉得of完全是多余的啊！而D当中from...to...比较好，因为后面时间状语是时间点，所以to后面就是表示到了2000年，平均气温增加了多少，而且project sth to我在牛津高阶上也看到了被动形态的句子，没有错，求解答啊！！
