Sandy: I'm really excited about seeing the famous paintings by Picasso.
Wu Lan: Me, too! I'm glad Mr. Smith chose the art museum for our school trip this year.
Sandy: I'm going to bring my new camera to take lots of photos!
Wu Lan: Oh, no. Mr. Smith says we must not take photos. It's not allowed in the museum.
Sandy: That's too bad! Do you think we may be allowed to take photos if we don't use a flash?
Wu Lan: Hmm... I think they just want to protect the paintings. So if you don't use a flash, then it may be OK.
Sandy: Yeah. I think we should be allowed to do that. I'll bring my camera anyway.

Mom Knows Best
妈妈最懂
When I was a tiny baby crying all night, my mom sang to me and stayed by my side.
When I was tired and hungry, she gave me food and warm arms to sleep in.
When I was two running through the field, she made sure I was safe and kept me from danger.
When I fell and hurt myself, she gave me a hug and lifted me up.
When I was seven coughing badly, she said no ice-cream for me.
But I talked back loudly, "I should be allowed to eat some! Give it to me now!"
When I was nine watching scary movies, she said it'd give me awful dreams.
But I shouted back angrily, "I should be allowed to watch it! I'm not a baby!"
When I was a teen going out with friends, she said, "Please be back by ten!"
But I talked back again — "I should not be told what to do! I'm seventeen now!"
I should be allowed to eat some!（我应该被允许吃一些！）I should not be told what to do!（不应该被指挥做什么！）should + be + 过去分词 = 应该被……
诗歌形式
本文是一首诗歌，采用排比结构(When I was... she.../But I...)。每段描述一个年龄段妈妈的爱与约束，最后一段表达醒悟与感恩。
Now I'm an adult, thinking back to those times.
I coughed for days after eating that ice-cream
And had scary dreams after watching that film.
I was late for school from staying out past ten.
I regret talking back, not listening to Mom.
Mom knows best, and for me she wanted only the best!
Many teenagers have hobbies. But sometimes these can get in the way of their schoolwork, and parents might worry about their success at school. Teenagers often think they should be allowed to practice their hobbies as much as they want. Do you agree?
They should be allowed to practice their hobbies.（他们应该被允许练习爱好。）情态动词被动语态贯穿全文。
Liu Yu, a fifteen-year-old boy from Shandong, is a running star. He is on his school team and has always wanted to be a professional runner when he grows up. However, his parents won't allow him to train so much. "Of course we want to see him achieve his dreams," says Mr. Liu. "And we know how much he loves running. My wife and I have supported every one of his races. We have nothing against running! But we think our son needs to think about other possible jobs. He's getting older now, so he needs to think about what will happen if he doesn't end up as a professional runner."
Liu Yu，山东的15岁男孩，是跑步明星。他在校队，一直想长大后成为职业跑步运动员。然而，他的父母不让他训练那么多。「我们当然想看到他实现梦想，」刘先生说。「而且我们知道他多么爱跑步。我和妻子支持他的每一场比赛。我们不反对跑步！但我们认为儿子需要考虑其他可能的工作。他现在长大了，需要想如果没有成为职业跑步运动员会怎样。」

Liu Yu doesn't really agree. "Well, I think I should be allowed to decide for myself," he says. "My parents have always taught me how important it is to work hard at school and enter university. I understand this, but I'm serious about running. It's the only thing I've ever wanted to do." His parents believe that Liu Yu should study hard in the evenings so they don't allow him to practice running at night. "Maybe he thinks it's too strict or unfair," says Mrs. Liu. "But we think we're doing the right thing. He needs to spend more time on his homework because becoming a professional sports star is a difficult dream to achieve."
Liu Yu不太同意。「嗯，我认为我应该被允许为自己做决定，」他说。「我父母一直教育我在学校努力学习、上大学有多重要。我理解这个，但我对待跑步是认真的。这是我唯一想做的事。」他的父母相信Liu Yu应该晚上努力学习，所以他们不允许他晚上练习跑步。「也许他觉得太严格或不公平，」刘太太说。「但我们觉得我们在做对的事。他需要花更多时间在作业上，因为成为职业体育明星是一个很难实现的梦想。」

My parents have always taught me how important it is to work hard.（父母一直教育我努力学习有多重要。）how + adj + it is + to do。
Liu Yu still disagrees. "I know my parents care about me. They always talk about what will happen if I don't succeed. But I will! I'm a quick runner! I think I should be allowed to make this choice myself. Only then will I have a chance to achieve my dream."
Liu Yu还是不同意。「我知道父母关心我。他们总讨论如果我不成功会怎样。但我会成功的！我是一个跑步很快的人！我认为我应该被允许自己做这个选择。只有这样我才有机会实现我的梦想。」
