Ted is a boy--- is easy to get along with,all of us like him

很高兴为你解答.
保证正确率~!
正确答案是：
Ted is a boy【 who /that】 is easy to get along with.All of us like him very much
特德是一个平易近人的男孩,我们都很喜欢他.
这里定语从句缺主语,修饰人,用 that / who 都可以,修饰 boy,最好是用 who.
祝开心~!

who,这里缺一个定语从句的引导词，根据前面的先行词a boy，需要选用who

who 定语从句，先行词为人，用who。ted是一个容易相处的人，我们都非常喜欢他。用that也可以，一样
