1. consider的基本用法。

He was considering how to do the work.他正在考虑怎样做这项工作。
He considered how he should answer the question.他考虑怎样回答这个问题。
②认为，把……当作，后常接从句或复合结构。
e.g. He considered me(as)a friend.他把我当成朋友。
They considered me too young to do the work.他们认为我太年轻，不能干这份工作。We considered him to be a good student.我们认为他是个好学生。

③consider用于被动语态中。

2. means方法、手段、工具，单复数同形，要根据具体语境确定其单复数，它常用于下面一些短语中，by means of通过……的方式，by this/that/these/those means通过这种（那种，这些，那些）方式。by no means决不。
way常与in连用，in this way用这种方法。means为动词，意为“打算”时后接不定式，意为“意味着”时后接动名词。meaning为名词，意为“意义，含义”。
e.g. Thoughts are expressed by means of words。思想是借助语言文字来表达的。
He hopes to solve the problem by peaceful means.他希望通过和平的手段来解决问题。There seems no means of knowing it.似乎无法知道它。
3. experience n. 经验，不可数名词经历，可数名词
vt. 体验
experienced adj.有经验的，老练的，熟练的
e.g. Our country has experienced great changes in the last fifty years.
She is a teacher with twenty year s’ experience.
Our journey was quite an experience.
He experienced great hardship for the first time in his life.
He is very experienced in money matters.
4. watch out 当心，小心。如果加宾语，需借助介词for e.g. Watch out! There is a car coming.
Watch out for cars when you cross the street.
Watch out for the thief while you are shopping.
5.danger n. 危险,为抽象名词,常用作不可数名词,可用于下面短语中:in danger在危险中,be in danger of有……危险，out of danger脱险，其形容词为dangerous。
e.g. We should help others whenever they are in danger.我们应当帮助有危险的人们。He was in danger of losing life at that time.他那时有生命危险。
He has been very ill，but the doctors say that he is now out of danger.
区别：dangerous 和in danger
dangerous 表示“危险的”，指句子的主语对别人有危害。in danger表示“处于危险的状态里”，指句子的主语的处境。
e.g.(1) He told me that the girl was in danger, so I went to help her.
(2) The man was dangerous, we must be careful with him.
danger如果用于抽象名词具体化，即指“有危险的人（物），危害”时，为可数名词。
e.g. A busy street is a danger to children.
Do you know the dangers of smoking?你知道抽烟的危害性吗？
6. protect vt. 保护
e.g. The soldiers were fighting to protect their country.战士们正在为保卫祖国而战。
②protect …from保护……不受……的影响, 而prevent/stop/keep…from…意为“阻止……做某事”
e.g. (1) The doctors try to protect people from SARS.医生们努力保护人民不受到非典的影响。
(2) I will protect you from danger.我会保护你不受到危险（威胁）。
(3) The trees will protect the sand from being washed away.这些树会保护土壤不被冲走。
(4) The rain prevented us from going out.
(5) We wear sunglasses to protect our eyes from the sun.
(6) We wear sunglasses to prevent the sun from hurting our eyes.
7. as with hiking = as it is with hiking 就像进行徒步旅行一样，作方式状语，其中it is 省略。
as引导的状语从句中如果是it is+ 表语，it is可以省略，如as soon as possible = as soon as it is possible.
