题型要求肯定句变为否定句,其规则是“若原句中有情态动词can/may/would/could
等时,肯定句变否定句,直接在这些词后面加not,即can not/would not/could not等;
如果原句中没有情态动词时,则需借助于助动词“do/does/did”来构成,如果原句时态为一般现在时,则用“do/does”,does 用在第三人称单数前面,而do用于其他人称。did用于一般过去时态。
那么上述的句子时态是一般过去时态,又没有情态动词,所以就借助于助动词did,原句就改成了“She did not became a skating champion when she was ten.”
