28、h_ he is still a disabled boy.文章大意：本文是一篇记叙文。Tom是一个残疾男孩，他不能像正常人一样走路。妈妈给他买了一个机器人Jimmy作为陪伴。尽管他仍然是一个残疾人，但是在Jimmy的陪伴下他恢复了自信。解析：1考查名词。physical为形容词，其后应用名词。故答案为disability。2考查冠词。normal boy是可数名词单数形式，前面用a泛指“一个”。故答案为a。3考查定语从句。设空处引导定语从句，先行词为robot，从句中指“机器人的名字”，故答案为whose。4考查分词作状语。本处take与句子主语Jimmy之间为主动关系，应用现在分词作伴随状
29、语。故答案为taking。5考查动词的时态。根据前半句的shows可知此处是并列的谓语动词，应该用一般现在时态，故答案为tries。6考查固定搭配。protect.from doing sth.保护免遭；再根据句子主语和harm之间是被动关系，所以这里用动名词的被动式，故答案为being harmed。7考查替代和时态。句意：他鼓励汤姆试着走路。汤姆确实这样做了。So主语助动词do/does/did，此处表示与上文动作一致，用助动词do/does/did代替上文相同的动作。根据Some days ago，可知句子用一般过去时态，故答案为did。8考查介词。make fun of是固定词组，意为“嘲笑”。故答案为of。9考查形容词或固定结构。句意：这一次，汤姆适应了这种情况，再也没有感到笨拙。此处用形容词adaptable作表语，也可用固定结构be adapted to，故答案为adaptable/ adapted。10考查连词。分析句意为“尽管他仍然残疾，但他重新获得了自信”，可知应填though引导让步状语从句。
