2. alone adv.   Without any companions 独自地;孤独地
示例
       I don't like going out alone after dark. 我不愿意天黑后独自外出。
用法
解析along 和lonely:
(1)alone 既可用作形容词,又可用作副词,意思是“独自的(地);单独的(地)”,侧重于说明独自一人,没有同伴或助手。alone和on one's own,by oneself意思相近。alone用作形容词时,一般与be 动词连用,在句中作表语。例如:She is alone at home. 她独自一人在家。alone 用作副词修饰动词时,放在动词后面作状语。例如:I like to work alone. 我喜欢独自一人工作。alone 用作副词时,也可作定语,意思是“只有;仅仅”,但必须置于它所修饰的名词或代词之后。例如:This year alone, we've already planted ten thousand trees. 仅是今年,我们已经载了一万颗树。
(2)lonely只用作形容词,它在句中既可作定语,也可作表语,表示“孤独的;寂寞的”。该词带有“孤寂”的感情色彩。用作定语时,意思为“孤单的;荒凉的;偏僻的”等。例如:That's a lonely island. 那是一个荒凉的岛屿。Lonely用作表语时,可以表示“孤寂的;寂寞的”。例如:I was alone but I didn't feel lonely. 我独自一人,但我并不感到孤独。
词汇拓展
常用搭配:let / leave somebody / something alone 不干涉某人或某物;听其自然
                         let alone 不管;不必考虑
谚语:An evil chance seldom comes alone. 祸不单行

3. dress  v. put clothes on yourself or someone else 穿衣
示例
Is she old enough to dress herself yet? 她会自己穿衣服了吗?
用法
dress还可以用作名词,表示“女服;连衣裙;服装”。例如:Mary wore a long red dress last evening. 玛丽昨晚穿了件红色的连衣长裙。
辨析dress,put on 和wear:
(1)用作动词时,dress既可以表动作,也可以表状态,常用人作宾语,意思是“……穿衣服”,例如:She is only a girl of three. She can't dress herself. 她只是一个三岁的女孩,她还不能自己穿衣服。需要注意的是,在表示“给自己穿衣”时,我们通常说dress oneself (= get dressed);当dress表示状态时,一般要用be dressed in 结构,例如:She was dressed in a red coat. 她穿着一件红色的上衣。
(2)put on 意思是“穿(戴)上”,强调动作。例如:He put on his coat and went out. 他穿上大衣就出去了。
(3)wear意思是“穿(戴)着”,强调状态。例如:Lucy's mother often wears a pair of glasses. 露西的母亲常常戴着一副眼镜。
词汇扩展
常用搭配:dress (somebody) up (in something / as somebody or something) 化妆打扮
谚语:Eat to please myself, but dress to please others. 吃是使自己受用,穿是使别人受用。

示例
The tree was probably a hundred years old. 这棵树可能已经有一百年了。
Hundreds of people attended the famous director's farewell concert. 好几百人出席了这位著名指挥家的告别音乐会。
用法
hundred 用于数词或含有数量意义的词之后,一般不用复数形式,例如:three hundred, a few hundred 等。但当hundred 表示“成百的;许多的”意思时,它面前不用具体数字,而常用hundreds of 结构。注意hundred 在这个结构中要用复数形式,前面可加some,a few,several等词修饰。例如:Her coat cost hundreds of dollars. 她的大衣价值几百美元。类似的搭配还有thousands of数以千计的;许多的,millions of 数以百万计的;无数的。

Science Daily (June 24, 2009) — Bioengineers at Duke University have developed a laboratory robot that can successfully locate tiny pieces of metal within flesh and guide a needle to its exact location -– all without the need for human assistance.

Science Daily (Feb. 28, 2008) — The type of robot chosen as a personal companion by participants at the University of Hertfordshire Science and Technology Research Institute's (STRI) Showcase is likely to depend very much on their personality type.

Science Daily (Aug. 29, 2008) — Whether driving on the highway or walking down the street, we pick up on both deliberate signals and unconscious cues to predict what other people are going to do and act accordingly. But robots have trouble following each other around, for example, when a leader turns a corner and disappears from sight.

Science Daily (Oct. 21, 2004) — 20 October 2004 – The chances of having an obedient robot do unwelcome or dangerous jobs have increased tremendously, with orders for industrial robots rising to a record 18 per cent in the first half of this year, a new report co-sponsored by the United Nations Economic Commission for Europe (ECE) says.

Cars are becoming more popular in China and around the world. They have many advantages, but they also have many disadvantages. For example, a car uses more natural resources than a family set of bicycles and causes pollution. It also takes up much more space. In some countries, teenagers get their own cars and driving is a popular activity in songs and movies. Many American films are so-called road movies. In these movies, two or more people set off on a trip to see new parts of their country and get to know each other better along the way.
