Question

用单词合适的形式填空
Some areas of concern distract our attention away from the main problem on which we need to remain ____(focus).
书上给的答案是focused,

Answer 1

remain作系动词
表示“一直保持”、“仍然（处于某种状态）”
后接形容词 后面接focus时,focus要变成focused,看成形容词形式,意思“专心的;集中精力的”.也就是remain+形容词的句式
Some areas of concern distract our attention away from the main problem on which we need to remain focused 一些地区从主要问题中分散了我们的注意力,而那些正是我们该集中精力的.
