【解析】

本文讲述美国有一种新型的苹果保鲜长达一年，科学家花了20多年才生产出来，在美国的超市可以买到。

1.句意：苹果在冰箱里能保鲜多久？

根据下文“Maybe just three or four weeks.可能只有三四个星期。”可知，此句应用how long询问多长时间。故填long。

2.句意：但是在美国有一种新型的苹果。

通读全文可知，时态是一般现在时。此句是there be结构，遵循就近原则；空后“a new type”是单数，故用is。故填is。

3.句意：它（它们）可以持续长达一年！

此处应用代词代替前文中“a new type of apples”；表达一类事物时，可用名词单数或复数，故代词可用it或they。故填It/They。

4.句意：这个苹果被称为宇宙脆。

再次提到同一事物时，名词前用定冠词the。故填The。

5.句意：华盛顿州立大学的科学家们研究并培育了这种新型苹果。

studied和grew皆为动词过去式，故用and连接，作并列谓语。故填and。

6.句意：他们花了20多年才生产出来。

根据句意可知，时态是一般过去时。句型为It takes sb. some time to do sth.某人花费多少时间做某事；take过去式took。故填took。

7.句意：这个月要减价出售。

根据下文“You can buy it in the supermarket of the US.”可知，应是销售苹果。on sale销售，固定短语。故填sale。

8.句意：你想尝试这个新苹果吗？

have a try尝试，试一试，固定短语。故填try。
