Answer 1

分析 succeeded in

解答 答案：succeeded in
表示成功的做某事結(jié)合后面的setting用succeed in doing sth，這里是說last year去年的事情用一幫過去時(shí)，succeed的過去式succeeded，故答案是succeeded in．

點(diǎn)評(píng) success，名詞 可數(shù)名詞（成功的人或事）； 不可數(shù)名詞（成功）
如He is a great success as a writer
Failure is the mother of success
succeed，不及物動(dòng)詞 succeed in doing sth
如He succeeded in swimming across the river 
successful形容詞，成功的
如 He is a successful writer．
