308.Thus, for example, we should expect to see consumers is a positive mood state evaluate products in more of a favorable manner than they would when not in such a state.

英語四級譯文:
因此，比如，我們應該可以看到，消費者處在積極情緒狀態下比處在消極情緒狀態下更能以一種嘉許的態度評價產品。

四級詞匯講解:
本句的主干是we should expect to see...。其中，consumers in a positive mood state evaluate products in mare of a favorable manner than they would when not in such a state是省略了引導詞that的賓語從句，該賓語從句的主干是consumers evalute products; in a positive mood state作consumers的后置定語。

英語四級考點歸納:
探析that在名詞性從句中的省略情況。
名詞性從句一般包括主語從句、表語從句、賓語從句和同位語從句。that引導名詞性從句，本身無詞義。

that引導主語從句或同位語從句時一般不能省略，而引導賓語從句或表語從句時可以省略。如:
1)No one can deny the fact that China has become one of the leading powers in the world.沒有人可以否認，中國已經成為世界上的主要大國之一。(同位語從句的引導詞that不能省略)
2)He thought ( that ) he would pass the exam this time.他認為這次可以通過考試。(賓語從句的引導詞that可省略)
