1.think abut ding sth. 考虑做某事-cnsider ding This is a big issue ; we need mre time t think abut it. 这是个重大问题，我们需要花较多的时间考虑。[拓展] 含有think的其他短语：think highly f 对……高度评价　think little f 轻视……；对……不假思索 [辨析]think f；think abut；think ver(1)think f意为“考虑到、想到”，后常接代词、名词或动词-ing形式；意为“认为”时，一般用于疑问句中，与what连用。基本意思是“想，思索”，指使一件事情在头脑中不断地浮现或使这件事保持这种浮现的状态，可以表示“想”的动作，也可以表示“想”的状态。还可指“以为，认为”，指某事在头脑中形成一个固定的概念，“想”的结果。
I ften think abut my friends back hme. 我常常想起老家的朋友。(2)think abut可接名词、动词-ing形式或由疑问词引导的不定式或宾语从句，表示“考虑……”。Dn't rush me. I need time t think abut it. 别催我。我需要时间考虑一下。(3)think ver意为“仔细考虑”，后接名词或代词作宾语。当后接代词时，应把代词放在ver之前。We must think ver what he said. 我们必须仔细思考他说的话。
2. neither adv.也不—I can't swim. 我不会游泳。—Me either. 我也不会。—I dn't want t g shpping. 我不想去购物。—Me neither. 我也不想。(1)neither用作形容词，后接名词单数，意为“（两者中）没有一个”Neither bk was very interesting. 两本书都不是很有趣。(2)neither用作代词，后接“f+名词”Neither f us felt like ging ut. 我们两个都不愿意出去。(3)neither用作连词，常与nr连用，构成neither…nr…结构，意为“既不……也不……”，连接同等的句子成分。当连接主语时，动词与靠近它的主语一致。Neither he nr I like cffee. 我和他都不喜欢咖啡。
3、get t 触及；接触；到达 get t作“触及；接触”讲时， 和 reach意思相近。get t还可作“到达”讲，后接地点，相当于reach或arrive at/in。 当 get t 和arrive at/in 后接here, there 或hme 等表地点的副词时，省略介词 t, at或in。arrive是不及物动词，可单独使用。When did yu get/arrive/reach hme yesterday? When did yu arrive? 你什么时候到的？
4、I thught yu liked Mars. 我原以为你喜欢火星。 英语中表示过去曾经有某种想法，但事实上并非如此，即“我原以为/原想……”之类的概念时，常用“I thught…”，此时宾语从句要用过去的某种时态。I thught they were interested in this bk. (1)“I think…”是指现在这样认为I think yu shuld think it ver. (2)含有think, believe, suppse, expect, imagine等动词的宾语从句的否定句应将从句的否定词转移到主句中，即主句的谓语动词用否定形式，从句的谓语动词用肯定形式。I dn't think I knw yu. 我想我并不认识你。 (1)否定转移的反意疑问句应与从句的主语与时态保持一致。 I dn't think Kate can sing, can she? (2)若谓语动词为hpe，宾语从句中的否定词不能转移。 I hpe yu weren't ill. 我想你没有生病。
5、There's n fruit r vegetables. 没有水果和蔬菜。 n fruit r vegetables意为“没有水果和蔬菜”，r用于否定句，连接两种或多种事物。I have n brthers r sisters. n＋单数可数名词＝nt (…) a/an＋单数可数名词； n＋复数可数名词/不可数名词＝nt (…) any＋复数可数名词/不可数名词Kate is n teacher.＝Kate is nt a teacher. He has n brthers.＝He des nt have any brthers. n用作形容词时，可直接放在名词之前，如果名词前有a, any, much, many, enugh等单词时，要用nt，不用n。
