单选题
1.[阅读判断]Despite other explanations,the real answer in my opinion lies partly in the child himself,partly in the behavior of the people around him.
Q：The reason why children learn their mother tongue so well lies solely in their environment of learning.
A.True
B.False
C.Not Given
正确答案：B
答案解析：答案选B.原文说的是儿童之所以能够完全掌握母语部分原因在于儿童自身，部分原因在于孩子周围人们的行为。问题句说“儿童母语学得好的原因只是因为他们的学习环境。”此处solely的表述是错误的。
