小題2:don’t sell
小題3:has forgotten
小題4:would take
小題5:thought
小題6:to stay   
小題7:had rung/rang
小題8:studying

小題1:考查被動語態(tài)。主語和謂語train是被動關(guān)系，故用被動語態(tài)。故填be trained。
小題2:考查被動語態(tài)。sell, wash等詞，當(dāng)表示事物本身的屬性時，用主動表示被動，故填don’t sell。
小題3:考查時態(tài)。根據(jù)is可知，是現(xiàn)在的情況，句意是“恐怕他已經(jīng)忘記要去參觀博物館了”。故填has forgotten。
小題4:考查時態(tài)。根據(jù)were可知，從句用過去將來時。故填would take。
小題5:考查時態(tài)。根據(jù)情境可知，“我”原先認為......，故用過去時。故填thought。
小題6:考查固定句型。have no choice but to do sth別無選擇只好做某事。故填to stay。
小題7:考查時態(tài)。在完成剩下的題目之前，鈴響了。用過去完成時或過去時皆可。故填had rung/rang。
小題8:考查固定搭配。devote oneself to doing sth“致力于......”。故填studying。
