阅读理解。 Friend is better than fortune. Friend is worse than poison in some cases. The two sentences above are opposite and seem to be unreasonable but they can be explained as follows: the first refers to all good friends who drive us towards good while the second all bad ones who lead us to wrong ways. My ideal(理想的) friend is of course a good friend whose goodness is shown below-he has no bad likings, such as smoking and drinking. He lives in frugality(节俭). He studies hard so as not to waste his golden time. At home he honors his parents and loves his brothers; at school he respects his teachers and shares feeling s of his classmates. He treats those truly who are true to him. In a word, he has all the good characters better than mine. I can follow him as a model.
