如:

He has turned teacher. = He has become a teacher. 注意:系动词turn后表示身份或职务名称的名词前多不用冠词。
(4)有些系动词既有系动词的功能，又保留实义动词本身的含义。如:rise, stand, blow, wear等，后面一般多接形容词。如:
She stopped and stood quite still.
The window blew open.
The material has worn thin.
动词contribute的用法搭配:
1. 表示“捐献”“捐助”“捐款”时，无论用作及物还是不及物，均通常与介词to(有时用towards)连用。如:
Every worker contributed 100 yuan to the Red Cross. 每个工人向红十字会捐赠100元。
He contributed a lot good ideas to the discussion. 他在这次讨论中提出了很多很好的建议。
2. 当contribute (…) to后接动词时，通常用动名词(因为to是介词)。如:
Everyone on the team contributed to winning the game. 球队的每个人都为赢得比赛而作出贡献。
He contributed much time to studying English usage. 他把许多时间用来研究英语惯用法。
但是，有时也可用动词原形(即将 to 视为不定式符号)。如:
We all contributed money to buy Richard’s present. 我们都凑了钱给理查德买礼物。
动词take的常见用法与搭配:
1. 表示“拿去”“带去”等，与 bring(拿来)方向相反。如:
Please take the empty cup away and bring me a cup of tea. 请把这个空杯拿走，给我倒杯茶来。
若语义需要，其后可带双宾语;若双宾语易位，用介词to引出间接宾语。如:
Please take him a cup of tea.=Please take a cup of tea to him. 请给他端杯茶去。
有时表示“拿去”可能与方向无关。如:
He took the box to the farm. 他把那个箱子带到了农场。
2. 表示“搭乘(交通工具)”，比较下面的同义表达:
他决定乘出租车去火车站。
正:He decided to take a taxi to the railway station.
正:He decided to go to the railway station by taxi.
3. 表示“认为”“当作”等，通常与 for, to be, as 连用。如:
He took me for my brother. 他错把我当成是我兄弟。
I took him for an honest man [to be honest]. 我看他为人老实。
按传统说法，take…for 往往指不合事实地“误认为”，而 take…to be [as] 则可能指正确地也可能指不正确地“认为”，但现代英语已不完全遵循此规则。
4. 表示“花费”，主要用于时间，有也用于人力、人手、劳力、精力、脑力等。如:
The flight will take three hours. 路上要飞3小时。
It takes patience. 做这工作需要耐心。
It takes two to make a quarrel. 一个巴掌拍不响。
It took three men to lift the box. 抬这个箱子要3个人。
It takes a lot of labor to build a railway. 修筑一条铁路要花费许多劳动力。
比较以下同义表达:
他写这本书花了5年时间。
正:It took him five years to write the book.
正:It took five years for him to write the book.
正:The book took him five years to write.
正:He took five years to write the book.
正:He took five years writing the book.
以上各句均可说，但以第一句最为普通。
在现代英语中take有时可用于金钱。如:
It takes a lot of money to buy a house like that. 买那样的房子需要很多钱。
It will take ten million dollars to build the library. 建这个图书馆要花1,000万美元。
5. 用于take to，用法如下:
(1) 对……产生好感，开始喜欢
I took to her the moment I met her. 我一见到她就立刻对她产生了好感。
(2) 形成…的习惯，沉溺于(通常后接动名词)
He soon took to drinking again. 不久他又喝起酒来。
(3) 前往(某处)，求助于
The criminal took to the woods to hide. 罪犯跑到树林里藏起来了。
He was ill and had to take to bed. 他病倒了，只好卧床。
动词walk用作动词时的及物与不及物:
1. 用作动词，表示“步行”“散步”等，是不及物动词。如:
He walked away sadly. 他伤心地走了。
Walking in step is not easy. 要走齐是不容易的。
Don’t walk on the grass. 不要在草坪上走。
2. 有时用作及物动词，但用法非常有限，主要见于以下情形:
(1) 表示“陪着……走”“护送……走”。如:
He offered to walk her to the station. 他提出陪她去车站。
(2) 表示“带着(宠物)散步”“遛(狗、马等)”。如:
Between one and two I was walking the dog. 一点到两点之间我在遛狗。
(3) 表示“步行走过(一段距离)”。如:

(4) 表示“步行沿着……走”“步行走过……”。如:

有时及物和不及物两种用法可能会混用。如:
