[解析]
My little cousin is greatly interested on science.And he does some dangerous experiments sometime.Although his parents want to encourage him to be∧great scientist,at times they worry about his safety.Last week,when my cousin was doing an experiment,he hurts his thumb.My aunt felt sadly and wanted him to stop from doing that experiment.However,my cousin didn't want to give up.She said,"Many scientists got hurt when they were doing experiments,so they didn't give up."My aunt had to let him finish the experiments and he finally succeeded in finish it.
详解:
1.on 改为in;考查介词,be interested in…是固定搭配,意为"对…感兴趣".
2.sometime改为sometimes;考查副词,sometimes是副词,意为"有时";sometime意为"在某一时候",分析句意为"有时候他做一些危险的实验"故用sometimes.
3.be后面加 a;考查冠词,scientist是一个可数名词,前面用冠词a泛指"一个",一个伟大的科学家.
4.hurts改为hurt;考查动词的时态,根据时间状语Last week可知句子要用一般过去时,动词hurt的过去式和过去分词和原形一样.
5.sadly改为sad;考查形容词,此处用形容词sad放在系动词feel后面,构成系表结构.
6.去掉from;考查固定短语,stop doing sth意为"停止做某事".句意:想要他停止做这个实验.
7.She 改为He;考查人称代词,本句的主语是my cousin,是男性,故使用he.
8.so 改为but;考查连词,分析句意为"很多科学家在做实验的时候都受伤,但是他们都没有放弃".所以下文之间存在着转折关系,故用but.
9.experiments改为experiment;考查名词,上文只提及这个实验,是一个单数名词.
10.finish改为finishing;考查非谓语动词,介词in后面接动名词doing形式,succeeded in doing意为"成功做某事".
