在教与学的活动中，()是基本矛盾。

When a friend is sad about a tragedy(悲剧)，it’s hard to know how to comfort(安慰) him/ her. But the worst thing you can do is say nothing. It could mean that you don’t care. You don’t have to say much.. A single supportive phrase doesn’t require absolutely perfect words to break the ice. Here are some conversation starters when life difficult situations have your tongue tied.

1. A friend loses his baby.

Don’t say: “Don’t worry. You’re so young. You’ll have another baby.” Do say: “ I’m so sorry. I can’t begin to imagine what you are going through, but if you want to talk about it, call me anytime.”

2. A guy deserts（抛弃）your friend.

Don’t say: “I never liked that rat bastard (坏蛋) anyway!” ( If the couple winds up reconciling (和解)， you could end up losing your friend.) Do say: “Breaking up is always hard to deal with, but I’m here for you, whatever you need.”

3. A friend has a death in the family.

Don’t say: “It’s God’s will.” or “I know exactly how you feel.” Do say: “I’m sorry about your loss. What can I do to help?”

4. A friend loses a job suddenly.

Don’t say: “Work is always boring. Those bosses didn’t suit you!” Do say: “I’m sorry for that, but I know there’s an even better job waiting for you there. Let’s think about possibilities.”

5. Someone’s pet dies.

Don’t say: “Gee! It was only a cat!” or “My roommate doesn’t like her dog and she is getting rid of her dog. Do you want it?” Do say: “I’m sorry, she was such a great cat. How long did you have it?”
