Hedied3yearsago.（）TFAttentions3.带有双宾语的动词，如give,send,bring,take,teach,show,tell,make,sing,write,read,sell,buy,pay,lend,pass,promise等，变为被动语态时，将间接宾语变为主语，若将直接宾语变为主语时，间接宾语前面要用相应的介词短语。Thecompanyhasgivenhimachancetoworkabroadrecently.→Hehasbeengivenachancetoworkabroadrecently(bythecompany).→Achancetoworkabroadhasbeengiventohimrecently(bythecompany).Attentions4.短语动词不能分割，而且不能省略短语动词中的介词或副词。判断正误:
