2. 西湖因其美景而出名。
The West Lake its beauty.
3. 她是大家所熟知的一名好演员。
She everyone as a good actress.

1. is known / famous as
2. is known / famous for
3. is known to

【分析】
要完成这道题，需先明确be known for、be known as、be known to三个短语的用法区别：be known for后接特点、原因类名词，意为“因……而闻名”；be known as后接身份、职业类名词，意为“作为……而出名”；be known to后接人或群体，意为“为……所熟知”。再结合每个句子的后半部分，判断应使用的短语，注意时态为一般现在时，主语是第三人称单数，be动词用is。
【解析】
1. 句中“a great scientist”是身份，对应短语be known as，主语Einstein是第三人称单数，故填is known as（也可填is famous as）；
2. 句中“its beauty”是出名的原因，对应短语be known for，主语The West Lake是第三人称单数，故填is known for（也可填is famous for）；
3. 句中“everyone”是群体，对应短语be known to，主语She是第三人称单数，故填is known to。
【答案】
1. is known / famous as
2. is known / famous for
3. is known to
