题目内容

. For breakfast he only drinks juice from fresh fruit ________ on his own farm.

A. grown B. being grown

C. to be grown D. to grow

解析:

A。由于名词fresh fruit与动词grow之间为被动关系，所以首先可排除选项D。而B和C虽然可以表示被动，但与句意不吻合，因为being grown表示一个正在进行的被动动作，to be grown表示一个尚未发生的被动动作，均不合题意。

Construction workers in Southern California have made a wild discovery. They were digging at a building site in San Timoteo Canyon (峡谷) when they unearthed hundreds of ancient animal fossils. Researchers say the bones hold important clues about the history of the region.
Nearly 1, 500 fossils were recovered from the dusty canyon. The remains are about 1.4 million years old. They include the bones of a new species of deer, several small rodents (啮齿目动物) and more. A giant cat fossil was also found. Scientists believe the animal was an ancestor of the saber- toothed tiger. Signs of plant life were uncovered as well.
