tendency 是源于動(dòng)詞 tend 的名詞,tend 是不及物動(dòng)詞,常與小品詞 to 搭配,表示“傾向于/有可能”.與動(dòng)詞同根的名詞在用法上依然保持動(dòng)詞的用法特點(diǎn),由此生成了如下的固定搭配：
have a tendency to do sth....有做某事的傾向/有可能做某事
因此本題應(yīng)該改為 Vanessa had a tendencyher mind often,so often in fact that her friends gave up expecting her to show up at their parties.
另如：
* Paint has a tendency to bubble and peell over time.油漆因年久而開始起泡并脫落.
* Fabric has a tendency to wrinkle.布料可能會(huì)起皺.
