1.A
It be .that 固定句型 用于强调
我昨天是在街上遇见玛丽的（这里是强调地点“在街上”,如果强调遇见的人是“mary”,则为It was Mary that i met in the street yesterday.）
2.A
原因和上题一样,不过在这里强调的是时间“十点”
3.B
worth是动词和名词.而句中应该填的是形容词,“值得的”.
worthwhile是表示“值得的”的意思,be worthwhile (for sb)to do sth“（对某人来说）做...是值得的”
worthy也表示“值得的”,但是它用于 be worthy of doing sth“做...是值得的”
