1．Sure，it's good to get along well with your teacher because it makes the time you spend in the classroom more pleasant.
And yes，it's good to get along well with your teacher because，in general，it's smart to learn how to get along well with the different types of people you'll meet throughout your life.
In fact，kids who get along well with their teachers not only learn more，but they're more comfortable about asking questions and getting extra help.This makes it easier for them to understand new materials and do their best on tests.When you have this kind of relationship with a teacher，he or she can be someone to turn to with problems，such as problems with learning or school issues.
Here is a question：what if you don't get along well with your teachers？In fact，teachers want to get along well with you and enjoy seeing you learn.But teachers and students sometimes have personality clashes（個性沖突），which can happen between any two people.If you show your teacher that you want to make the situation better，he or she will probably do everything possible to make that happen.By dealing with a problem like this，you learn something about how to get along with people who are different from you.
However，if a certain teacher isn't your favorite，you can still have a successful relationship with him or her，especially_____.Here are some of those responsibilities：
?Attend class ready to learn.
?Be prepared for class with the right pencils，books，and completed assignments.
?Listen when your teacher is talking.
?Do your best，whether it's a classroom assignment，homework，or a test.

2．Suppose you're in a rush，felling tired，not paying attention to your screen，and you send an email that could get you in trouble．
Realisation will probably set in seconds after you've clicked "send"．You freeze in horror and bum with shame．
What to do？Here are four common email accidents，and how to recover．
Clicking "send" too soon
Don't waste your time trying to find out if the receiver has read it yet．Write another email as swiftly as you can and send it with a brief title explaining that this is the correct version and the previous version should be ignored．
Writing the wrong name
The sooner you notice，the better．Respond quickly and briefly，apologising for your mistake．Keep the tone measured：don't handle it too lightly，as people can be offended，especially if your error suggests a misunderstanding of their culture （i．e．incorrect ordering of Chinese names）．
Clicking "reply all" unintentionally
You accidentally reveal（透露）to the entire company what menu choices you would prefer at the staff Christmas dinner，or what holiday you'd like to take．In this instance，the best solution is to send a quick，light-hearted apology to explain your awkwardness．But it can quickly rise to something worse，when everyone starts hitting "reply all" to join in a long and unpleasant conversation．In this instance，step away from your keyboard to allow everyone to calm down．
Sending an offensive message to its subject
The most awkward email mistake is usually committed in anger．You write an unkind message about someone，intending to send it to a friend，but accidentally send it to the person you're discussing．In that case，ask to speak in person as soon as possible and say sorry．Explain your frustrations calmly and sensibly -see it as an opportunity to clear up any difficulties you may have with this person．
（1）After realizing an email accident，you are likely to feel．
A．curious
B．tired
C．a(chǎn)wful
D．funny
（2）If you have written the wrong name in an email，it is best to．
A．a(chǎn)pologise in a serious manner
B．tell the receiver to ignore the error
C．learn to write the name correctly
D．send a short notice to everyone
（3）What should you do when an unpleasant conversation is started by your "reply all" email？
A．Try offering other choices．
B．Avoid further involvement．
C．Meet other staff members．
D．Make a light hearted apology．
（4）What is the passage mainly about？
