Back Ⅲ. Problematic Areas for This Unit 1、upset 可作动词、形容词和名词。作为不同词性使用时，它们的意义又是相互联系的。 2、busy 通常作形容词，也可转换用作动词。 3、once 一般用作副词和连词。 4、get over 忘却（不愉快的经历、情绪等）；克服（困难、难题）。该词组为及物动词词组，后接宾语。 5、hear from 收到------来信。该词组及物，后面须接“某人” 作宾语，相当于receive a letter from somebody. 6、put on weight 增加体重。与此同义，也可以说gain weight;反义词组为lose weight.这里的weight为不可数名词，其前可加修饰语，说明体重增加或减少的程度。 7、give up sth or doing sth. 放弃（做）某事。该词组及物，常接名词或动名词作宾语。 upset ⑴作动词时，通常表示： a. 使担忧，使不安。如： Do whatever your mother tells you, or you will upset her.b. 引起（胃）疼痛，难受。如： The Cantonese food upset her stomach. ⑵作形容词时，主要含有“担忧，着急，不快乐”等意思。如： He is upset about what she told him. She seldom gets upset when she is answered “no”. ⑶作名词时，表示“乱七八糟，混乱不堪的状态”或“造成这种状态的”。如： A complete upset of the classroom. Back busy ⑴作形容词时表示： a. 忙，忙碌。如： The teacher is very busy now.b. 繁忙的，用作定语
