in case 引导条件状语从句， 译为：“以防万一，以免”
You may find yourself facing one interviewer or a panel. The latter is far more intimidating， but do not let it worry you too much.
The interviewer will probably have a table in front of him/her. Do not put your things or arms on it.
If you have a bag or a case， put it on the floor beside your chair. Do not clutch it nervously or， worse still， drop it， spilling everything.
Shake hands if the interviewer offers his hand first. There is little likelihood that a panel of five wants to go though the process of all shaking hands with you in turn. So you do not be upset if no one offers.
Shake hands firmly － a weak hand suggests a weak personality， and a crushing grip is obviously painful. Do not drop the hand as soon as yours has touched it as this will seem to show you do not like the other person.
Speak politely and naturally even if you are feeling shy. Think before you answer any questions.
If you cannot understand ask： “Would you mind rephrasing the question， please？” The question will then be repeated in different words.
If you are not definitely accepted or turned down on the spot， ask： “when may I expect to hear the results of this interview？”
If you do receive a letter offering you the job， you must reply by letter （keep a photocopy） as soon as possible.
Good luck ！
语 法 As的用法
I.语 法
1.AS的用法
（1）用作介词时的基本词义，“作为，担任”，“像，似”。
介词短语在句子中可担任的成分：状语、定语、宾语补语和表语
（2）用作副词表示程度，as … as … 结构中
（3）用作连词，引导状语从句（比较、让步、时间、原因和方式状语从句）
（4）用作关系代词，引导定语从句，
（5）As用于常用习语中
2.过去分词、现在分词、不定式作定语的区别
分词作定语：
过去分词作定语，修饰名词、代词，表示被动、已经完成。
现在分词作定语，修饰名词、代词，表示主动、正在进行。
单个分词一般置于所修饰的词之前，但也有例外。
例如 an extended family 一个扩展了的家庭 / a singing girl 一个唱歌的女孩
a developed country 发达国家 / a developing country 发展中国家
the people concerned 有关人员
分词短语一般放在所修饰的词之后，例如：
A decision is a choice made from among alternative courses of action.
Have the letter inviting you for an interview …
现在分词的被动式和过去分词都表示被动，区别在于前者表示修饰的词正在承受的行为，而后者表示修饰的词已承受过了的行为。
例如： The problem being discussed is important. 正在讨论的这个问题很重要。
The problem discussed yesterday was important. 昨天讨论的那个问题很重要。
现在分词的完成主动式，表示动作已经完成。having done
现在分词的完成被动式，表示动作已经被完成。the decision having been made
不定式作定语
不定式作定语应当放在所修饰的中心词之后。例如：We have plenty of work to do.
一般来讲，不定式作定语时，表示动作将要发生。另外，还要注意的是不定式有三种时态，也有被动态。
3.分词短语作时间、条件、让步状语
为了表示明确的时间或条件，有时常在分词前面加上when， while， even if， even though， unless 等连词作时间、条件、让步等状语。
