托福閱讀試題：懷孕魚龍群

　　There are numerous unsubstantiated reports that natural vitamins are superior to synthetic ones，that fertilized eggs are nutritionally superior to unfertilized eggs，that untreated grains are better than fumigated grains and the like.

　　(并列同位語從句reports that…，that…，that…)

　　關(guān)于天然維生素優(yōu)于人造維生素，受精蛋比未受精蛋的營養(yǎng)價值更高，未經(jīng)熏蒸消毒處理的谷物比經(jīng)過處理的好等等報道屢見不鮮，但都沒有得到證實。

　　分句1：There are numerous unsubstantiated reports

　　分句2：that natural vitamins are superior to synthetic ones

　　分句3：that fertilized eggs are nutritionally superior to unfertilized eggs

　　分句4：that untreated grains are better than fumigated grains and the like

　　分句1是整個長句的主句，分句2、分句3和分句4是并列關(guān)系，共同構(gòu)成分句1的同位語從句。本句的意思是有很多沒有經(jīng)過證實的報道，然后并列了三個未經(jīng)過證實的報道的從句。
