She never keeps a promise.2.when 与 while 的区别：when 表示“当时候”，既指时间点，又指一段时间，when 引导的时间状语从句中的动词可以是终止性的也可以是延续性的。When the teacher came in, the students were talking.When she arrives, Ill call you.(主将从现)while 表示“当时候”，仅指一段时间，从句中的动作必须是延续性的，一般强调主从句的动作同时发生， while 还可以作并列连词，意为“ 而、却”，表示对比关系。Lisa was singing while her mother was playing piano.Tom is strong while his younger brother is week. 3. practice vt. 练习， 后接名词，代词或v-ing 作宾语。Your elder sister is practicing the guitar in the room.常跟v-ing 作宾语的动词有：考虑建议盼原谅：consider, suggest/advise, look forward to, excuse, pardon.承认推迟没得想： admit（承认）, delay/put off, fancy（幻想）.避免错过继续练：avoid, miss, keep/keep on, practice.否认完成能欣赏： deny, finish, enjoy, appreciate.不禁介意与逃亡： cant help , mind, escape.不准冒险凭想象： forbid, risk, imagine.4. everyday 与 every day 区别everyday adj. 每天的 在句中作定语，位于名词前。 This is our everyday homework.every day 副词短语， 在句中作状语，位于句首或句末。 He reads books every day. 5.be sure 的用法1. be sure of/about sth/doing sth，意为“确信.”；“对.有把握”。例如：He is sure of success. 他自信会成功的。若后面要接反身代词，则只能用 be sure of, 即 be sure of oneself,意为“有自信心”。例如：Joan will sit for an important examination next week, but she is not sure of herself. 琼下周要参加一个重要考试，但她对自己没有十分把握。2. be sure to do sth，表示说话人对句子主语作出的判断，认为句子主语“必定”、“必然会”、“准会”.。例如： It is sure to rain. 天一定会下雨。He is sure to have known about that. 他准会知道那件事。然而be sure to do 用在祈使句中，不是表示判断，而是表示
