314. Half of the employers expressed worries about employees' basic literacy and numeracy (计算) skills, while the biggest problem is with IT skills where two-thirds reported concerns.
译文
有一半的雇主表示对员工的基本读写和计算能力表示担忧，而最大的问题在于有三分之二的企业对员工的IT技能感到担忧。
点睛
该句是由表示转折关系的连词while连接的并列句，句子主干为Half of the employers expressed worries…, while the biggest problem is with IT skills。后半句中的where引导的是定语从句，相当于with which，which指代IT skills。express worries意为“表示担忧”。
