Money or Friendship or Both
1 Friends and money don't mix. It's a dangerous combination since a fight over money is one of the fastest ways to end a friendship. But what if a friend asks you to lend him or her some money? If you don't lend your friend the money, you risk losing the friend If you do lend your friend the money, you risk losing both the friendship and your money
2 We have to face facts, so here are some situations you might run across with your buddies (伙伴) - and some helpful tips (忠告) on how to deal with them. Think about why this person needs to borrow in the first place. If he is always living beyond his means, it's his fault, not yours. Any sensible person would not put himself in a position of debt so often. So simply say "no" to this friend. Even if your friend really needs that money for emergency use and you are willing to help him, before you dived into your pocket, follow this reality check: Do you have the extra money? Are you sure you don't need it? Are you willing to write off that amount if it's not returned? If your answers are negative, do yourself a favor and say "no".
3 Let's assume you can't stand saying "no" to your friend because you don't want him living off cat food. What do you do? Write down these details on a sheet of paper before opening up your wallet:
Amount of the loan.
Date of the loan.
Time of repayment.
Amount of interest (if any).
Lender's and borrower's signature.
This will at least keep the borrower from forgetting the loan so easily. If your friend's loan is past due, it's important that you ask him - and it's actually not rude. The longer you wait, the more you brood (忧伤), and the more your resentment builds.
4 You can send him a friendly reminder via e-mail. Tell him something like 'Tm going over my bank account and I'm just wondering when we'll be able to settle that money thing." E-mail saves you from an uncomfortable face-to-face confrontation. There is almost no chance of turning a bad reaction into an argument. Unlike a public conversation, an e-mail message will always be private.
5 After asking two or three times, you might have to wnte it off and the friendship with it. That's what happens. If he just doesn't have the money or is unwilling, then what kind of friend is that?

A Time to break off a friendship
B Unconditional assistance to friends in need
C Things to consider when you have to say "no" to your friend
D Things to think over when you don't want your friend to eat cat food
E Strategies for borrowing money

Understanding Autism
1 Autism (孤独症) is a life-long developmental disability that prevents individuals from properly understanding what they see, hear, and otherwise sense. This results in severe problems of social relationships, communication, and behavior. Individuals with autism have to painstakingly '(费力地) learn normal patterns of speech and communication, and appropriate ways to relate to people, objects, and events, in a similar manner to those who have had a stroke.
2
The cause of autism is still unknown. Some research suggests a physical problem affecting those parts of the brain that process language and information coming in from the senses. There may be some imbalance of certain chemicals in the brain. Genetic (遗传的) factors may sometimes be involved. Autism may indeed result from a combination of several "causes".
3 Most people with mental retardation (智力迟钝的)show relatively even skill development. Individuals with autism, however, typically show uneven skill development, with deficits (~欠缺) in certain areas - most frequently in their ability to communicate and relate to others - and distinct skills in other areas. It is important to distinguish autism from mental retardation or other disorders, since diagnostic (诊断的) confusion may lead to inappropriate and ineffective treatment techniques.
4 In general, individuals with autism perform. best at jobs which are structured and involve a degree of repetition. Some people who have autism are working as artists, piano tuners, painters, farm workers, office workers, computer operators, dishwashers, assembly line workers, or employees of sheltered workshops or other sheltered work settings.
