答案

解析

【分析】
首先明确方框内单词的词义与词性:perform(动词,表演)、shy(形容词,害羞的)、lazy(形容词,懒惰的)、compare(动词,比较)、hard-working(形容词,勤奋的)、loud(形容词,大声的)。解题时需逐句分析句意,结合句子的语法结构(如时态、词性需求)选择恰当单词并调整形式:第1句是一般现在时,主语为复数,需用动词原形;第4句有时间标志just now,需用动词过去式;其余句子根据语境需用形容词原形作表语或修饰名词。
【解析】
1. 句意:老师经常把学生的作业做比较来找出差异。固定搭配compare...to...表示“把……和……比较”,主语Teachers是复数,一般现在时,故填compare。
2. 句意:Lucy是我们班最勤奋的学生,所有科目都表现最好。修饰名词student需用形容词,hard-working符合语境,故填hard-working。
3. 句意:Tom是个很懒的男孩,从不帮父母做家务。修饰名词boy需用形容词,lazy符合语境,故填lazy。
4. 句意:Jack刚才在学校艺术节表演了一个节目。时间状语just now表示过去,动词需用过去式,perform的过去式为performed,故填performed。
5. 句意:她太害羞了,在全班面前说不出话。feel后接形容词作表语,shy符合too...to...结构的语境,故填shy。
6. 句意:音乐太吵了,我没法思考。so后接形容词,loud符合语境,故填loud。
【答案】
1. compare 2. hard-working 3. lazy 4. performed 5. shy 6. loud

2. 语境隐含音量的比较,需用loud的比较级louder,故填louder。
3. 修饰事物用boring,修饰人用bored,此处修饰movie,故填boring。
4. than是比较级标志,good的比较级为better,故填better。
5. 第一空为谓语动词,表过去动作,用performed;第二空为名词,用performance,故填performed, performance。
