英文 高中 6個月以前 想知道為什麼這題是no而不是not ・綜合測驗 1 Helping a friend in need is what a true friend does. But when money is involved, you need to think twice. L'obaning money to friends is 1 simple matter. This simple act can lead to a strained relationship. Friends can become enemies with unsettled debts. After all, some lessons are meant to be learned the hard way. Friendly 2 may be helpful for the moment. However, 3 is that the person must learn effective money management to prevent making the same mistake again. If you still think it's important for you to affirm your loyalty to your friend by lending to him, here's some advice for you. First, work up to losing the money. Some people become 4 when they don't get their money back. But since you have made the decision to help, that's the risk you have to take. It's also suggested that you write down how much money he borrows and when you expect to be paid back. Written records make everything clear and avoid future conflicts. 5 everything else, you need to talk with your friend about money management. The sooner he gets back on his feet, the sooner you get your money back. A test of friendship is done. (B) not (D) never Ab (A) no (C) none Pa 11.00 已解決 回答數: 1
