　　C General Information about Washoe

　　D The Gardeners Contributions Recognized

　　E Debate on Chimps Intelligence

　　5. Washoe could make signs to communicate

　　6. Some scientists doubted

　　7. Washoe taught three younger chimps sign language

　　8. The experimenters thought Washoe was intelligent

　　A if the Gardeners argument was sound

　　B because she was cleverer than other chimps

　　C when she wanted to eat

　　D while she was at a research center in Ellensburg

　　E because she could use sign language to ask for fruits

　　F while Washoe was learning sign language

　　答案與題解：

　　1. C 第一段主要介紹猩猩Washoe的出生地、死亡年齡、被帶到美國學習美式手語等一般情況。用General Information about Washoe來概括是很準確的。

　　2. B 第二段的關鍵句是In 1969， the Gardners described Washoes progress in a scientific report.隨后的句子簡略的介紹了Washoe的學習情況和結果，如已學會了250個單詞，并能用手語表達“該吃飯了”等概念。所以，Report about Washoes Progress in Learning Sign Language(選項B)是答案。

　　3. E 第三段介紹了對Gardener夫婦發表的報告有兩種不同的解讀。一派認為Washoe的手語能力只是機械重復、死記硬背、物質激勵的結果，不是智能的表現。另一派認為知識智能的表現，其證據是Washoe還能教三個小猩猩學習手語。爭論的焦點是猩猩有沒有智能。選項E用debate來概括上述爭論，所以是答案。

　　4. A 第四段解釋了為什么現在從事這項研究的科學家人數不多。部分原因是研究周期太長。

　　5. C 選C 的第四段第二句：Washoe made signs to communicate when it was time to eat.

　　6. A 第三段的上半段說了一些科學家對Gardener 夫婦的試驗的解讀所持懷疑態度。題干中出現的doubted引導我們選A.

　　7. D 依據是第三段的最后一句，即“He took Washoe to a research center in Ellensburg， Washington. There， Washoe taught sign language to three younger chimpanzees， which are still alive.”

　　8. E 本文第二段談到試驗的成果時有一個句子：“She could request foods like apples and bananas”。根據全段意思和上述句子，選擇E是正確的。
