Plan your items ahead of time to avoid over-packing.

If you have a good sense of what the weather will be like, you can be very careful in your planning. If not, bring versatile(万能的)items that will allow you to adapt to changing conditions. 【小题2】 If you won’t have an opportunity to wash your clothes, putting them away in a separate bag will keep you from having to mix the clean with the dirty.

How do actors and actresses memorize hundreds of lines? Memorizing lines takes practice and constant repetition. However, there are a few ways to make the memorization process run smoothly and quickly.

【小题1】

For most performers, there is no quicker way of memorizing lines. To learn lines, an actor must recite the play loud over and over again. Most rehearsals(排练) encourage this by running through the lines or having a"read-through". By the time the opening night arrives, most actors have spoken their lines hundreds of times.

Listen to your cast members

Sometimes inexperienced actors spend rehearsals looking at fellow performers, waiting patiently to say their next line. 【小题2】. This will help the actors learn their lines better because the context of the dialogue is absorbing.

【小题3】

Because there is often not enough rehearsal time, many performers find ways to listen to the play's dialogue during everyday activities. They use a tape recorder or an MP3 player to listen to the lines from each relevant scene. Some actors prefer to record the lines of all the characters, including their own lines. 【小题4】. Others like recording the lines of fellow cast members, and they leave a blank space so that they can insert their dialogue while listening to the recording.

Think positively and don't panic

Most actors will experience stage fright before the opening night. Actors forget lines now and then. When it happens, however, most of the time the audience never notice. If you forget a line in the middle of your performance, don't freeze. Stay in character. Keep the scene going to the best of your ability. If unfortunately you forget a line once, you will probably never forget that line ever again. 【小题5】.
