A. Giving B. Having given C. To give D. Given
解析：答案是D。因动词give与句子主语these teenage soccer players之间为被动关系，所以要用过去分词given。为便于理解，此题可改写为：If these teenage soccer players are given the right kind of training, they may one day grow the international stars.
34. _________from other continents for millions of years, Australia has many plants and animals not found in any other country in the world.
A. Being separated B. Having separated
C. Having been separated D. To be separated
解析：答案选C。强调动作发生在主句谓语动作之前时，原则上要用完成式（根据情况可用不定式的完成式或现在分词的完成式）。因为Australia与separate是被动关系，且separate发生在谓语动词has之前，所以用现在分词的完成被动式作原因状语。

It seems that our team has won.=our team seems to have won.第一句 看起来我们队要赢 第二句 看起来我们队已经赢了。
38. ________ by the advances in technology, many farmers have set up wind farms on their land.
A. Being encouraged B. Encouraging C. Encouraged D. Having encouraged

A. come B. comes C. to come D. coming
