解题技巧点拨
考查要点：
主要考查固定搭配，语法结构，句意理解(连词)，特殊句型
解题技巧点拨：
先分析结构，确定句子类型，再预判空格处可填单词的词性，然后根据句意、相似结构、搭配、同根词等确定所填单词，填写时注意名词的单复数、动词的形式。
1.先找谓语动词，如一句话有2个或以上谓语动词，则是复合句，缺少连接词，再判断是填从句连词还是并列连词。
2.主语和宾语中间填谓语动词，注意人称、时态和语态。
3.“冠词＋空格＋名词”，空格处通常是名词或形容词。
4.“空格＋名词”，如名词是可数名词单数，空格处通常是冠词；如果名词是不可数名词或可数名词复数，空格处通常是名词或形容词。
5.“动词＋(限定词)＋空格”，及物动词后通常是名词、代词，不及物动词后通常是副词。注意：“be动词＋空格”，空格处通常是实义动词的 ing、过去分词形式，或是
名词、形容词；“have/has＋空格”，空格处通常是实义动词的过去分词形式或名词，如此时空格后有名词，参考“空格＋名词”。
6. 主句无谓语动词，且句首空格，通常是感叹句或祈使句。
重点词汇、短语积累
1.device　n. 装置　
2.safety　n.安全　
3.degree　n.度数　
4.award　n.奖
