colormovies,too.這是一個含有定語從句的復(fù)合句。thatledtocolormovies是一個由that引導(dǎo)的定語從句，修飾前面的先行詞inventions。翻譯為“我也了解到了促使有色電影（出現(xiàn)）的發(fā)明物?！眎nvention在此處作可數(shù)名詞，意為“發(fā)明；發(fā)明物”，此外，invention還可作不可數(shù)名詞，意為“發(fā)明”。其動詞形式為invent,意為“發(fā)明；創(chuàng)造”。inventor作名詞，意為“發(fā)明家”。Edisoninventedalotofthings.Hewasagreatinventorandheisfamousforhisinventions.3.I’veneverbeencamping.我從未野營過。此句為現(xiàn)在完成進(jìn)行時，這一時態(tài)的結(jié)構(gòu)has/havebeen+現(xiàn)在分詞，表示從過去某一時刻一直延續(xù)至今的動作。在本句中，說話人使用這一時態(tài)來強(qiáng)調(diào)自己至今從未有過野營的經(jīng)歷，欠缺這方面的經(jīng)驗。
