Question

4. One day he was doing some frying at the stove        the oil sprayed from the pan. (get)

Answer 1

4. when his face got burnt by考查特殊句型和get的用法。get sth. done使某事被做，遭受。was / were doing sth. when sth. happened正做某事这时发生了(其他事) 」谅句型为固定句型。若表"刚做了什么这时……"或"正要做某事这时……"之意时，则分别用had (just / hardly)  done sth. when sth. happened和was / were about to do sth. / on the point / edgeofdoingsth. + when sth. happened。这组句型中，when-分句中的时态总是一般过去时。
