Question

【题目】（题文）Little Jack has learned to do lots of things on his own , ______ he is only four years old.

A. if B. though C. for D. since

Answer 1

【答案】B

【解析】句意：小杰克自己学会了做许多事情，尽管他只有四岁。A. if 如果； B. though 尽管 C. for 因为，为了； D. since自从；根据Little Jack has learned to do lots of things on his own , 和he is only four years old.之间是让步关系，所以用 though 引导让步状语从句；故选B
