答案

①practising ②A ③keep away from

解析

【分析】
本题包含三道英语基础题,需结合固定搭配和动词短语的用法解题:①考查固定搭配keep on doing sth,需将动词变为动名词;②需辨析keep相关短语的含义,结合句意选择合适的短语;③考查固定短语keep away from的用法,直接填写即可。
【解析】
①固定搭配“keep on doing sth”表示“继续做某事”,因此动词practise要变为动名词形式practising;
②逐一分析选项短语:A.keep off意为“不接近,避开”,符合“晚餐准备好之前别碰那个蛋糕”的句意;B.keep away后需加from才能接宾语,不符合此处结构;C.keep from意为“隐瞒、阻止”,D.keep on意为“继续”,均不符合句意,故选A;
③固定短语“keep away from”表示“远离”,符合句意,故填写keep away from。
【答案】
①practising ②A ③keep away from
【知识点】
固定搭配;动词短语辨析
【点评】
本题聚焦英语基础的固定搭配与动词短语,属于常见考点,只要牢记相关短语用法即可轻松解答,难度适中。

【分析】
本题是英语单项填空题,考查基础语法与词汇知识。解题时需先理解每道题的句意,再结合选项的用法、搭配及语境逐一分析,排除不符合的选项,选出正确答案。
【解析】
1. 第1题:句意:练习很重要。除非你经常使用这些新单词,否则你会忘记它们。选项中,when(当……时)、if(如果)不符合逻辑;unless意为“除非,如果不”,符合句意;until(直到)也不合适,故选B。
2. 第2题:句意:——这道数学题如此难,以至于我解不出来。固定句型“so+形容词/副词+that+从句”表示“如此……以至于……”,such修饰名词,此处difficult是形容词,故用so…that结构,选C。
3. 第3题:句意:把刀放在远离桌子边缘的地方,它可能掉下来伤人!固定短语keep off意为“使不靠近,远离”;keep away需加介词from;keep from意为“隐瞒”;keep on意为“继续”,故选C。
4. 第4题:句意:这张地图的方向是令人困惑的。它说左转,但箭头指向右!surprised(人感到惊讶的)、surprising(物令人惊讶的)不符合语境;confusing修饰物,意为“令人困惑的”;confused修饰人,意为“困惑的”,此处修饰directions(物),故选B。
5. 第5题:句意:老师说:“在椅子上坐直——弯腰驼背对背不好!”固定短语sit up意为“坐直”;sit down(坐下)、sit on(坐在……上)、sit in(列席)不符合句意,故选D。
