Energy drinks are not allowed _____ in Australia but are brought in from New Zealand.
A．to makeB．to be made
C．to have been madeD．to be making
B

試題分析：考查動詞不定式用法。固定詞組allow sb to do sth允許某人做某事，本題是這個結(jié)構(gòu)的被動語態(tài)sb be allowed to do sth，而且make與energy之間也構(gòu)成被動關(guān)系，也要使用被動語態(tài)的形式。本句不強調(diào)已經(jīng)被生產(chǎn)的意思，所以就使用一般式。故B正確。
點評：當(dāng)不定式的動作與名詞構(gòu)成被動關(guān)系的時候，就使用被動形式；構(gòu)成主動關(guān)系就使用主動形式。如果在謂語動作之前發(fā)生就使用完成式。
