这题怎么感觉那么怪异,肯定是我哪里没有开窍,哪位大牛 帮我讲解下?这个 researchers have discovered 插在路中间怎么这么怪异
啊,它前面是个完整的句子啊,怎么没有连词? 要是做插入语也不带这样插的啊。。后面那个画线的句子讲的是神马意思列? 对于这题我是一头雾水啊。。。谁能帮我拨开它神秘的面纱。。。答案是D

"researchers have discovered, "是插入句,忽略不考虑;后面的and句子的主语是A scrub jay ,所以用tends;tend不能接在can后面;最好的办法是,你把省略的主语带入句子中,一看就知道了;If 觉得是可有可无;OG的解释估计会说,if是wordy。
