Dear Jack, I remember the moment — it truly hit me that your autism(自闭症) lasted forever. I had already mentally planned our trips up north with the boys. I was going to spend endless hours playing baseball with you — like Grandpa did with me. When we said goodbye to kindergarten I knew it was real. I spent some time being sad. Now you are 8. You still have no words. We have never had one of those father-son moments I pictured when you were a baby. But I'm learning that's OK. I still have unbelievable things to offer as your dad, even if they weren't the things I originally expected. You have taught me to be patient. You have taught me that it's OK to be different and to be sad when life doesn't go as planned. You have taught me that it is OK to talk about those feelings and fight for what is right. Stand up and say this is wrong, and encourage others to stand up for you and say the same. My job on this earth is to create a world for you and other kids like you. Be the voice you don't have, and build the kind of community which I want to see you grow up in. I used to shy away from contacting people with disabilities or just not consider them. Before you were born, I was so caught up in my own world that I probably wouldn't have even noticed. Now, I see things differently. I notice. You did that for me. And hope my example will do that for others. Your mom and I have spent 8 years trying to find your voice. And honestly, we don't know if we ever will. I promise you I will spend my life keeping you safe and making this world better for you. What can be learned about the author? A. He is at a loss what to do to help Jack. B. He is to blame for Jack's present condition. C. He has changed his attitude to the disabled. D. He hasn't accepted the reality up to now.

II. 七选五 Exam Anxiety Has this ever happened to you? You've been studying hard for your midterm, but when you walk into your exam room, your mind goes blank, your heart races fast, you get sweaty palms and you find it hard to breathe. ___1___ Everyone feels stressed during exams. Usually, it results from a fear of failure, lack of enough preparation time and bad experiences of taking tests in the past. This is normal and often helps you work harder, think faster and generally improve your performance. ___2___ You may also feel that other people are managing the exam better than you. This can cause you to feel that your mind has "gone blank" on the information you know you have revised. ___3___ Some choose to ignore the problem, while others don't review because they think they will do badly anyway and even miss exams due to anxiety. It can also be really easy to think that if you don't try and then you fail, you won't feel as bad as if you fail after trying really hard. So what can you do to fight against the negative mindset and stay calm before and during your test? ___4___ Yes, this seems obvious, but it's worth repeating. If you feel confident that you've prepared thoroughly, you'll feel more confident walking into the exam room. The second tip is simple: just start. The blank page can maximize your anxiety. ___5___ You can always go back and change things later if needed, but a few quick answers can get the ball rolling. Besides, allocating your time is equally important. Look through the whole test before getting started. Mentally allocate how much time you'll spend on each section. If there's time to check the paper, it will be even better. A. The first thing you should do is to be prepared. B. People often deal with exam stress in many unhelpful ways. C. If these classic signs of exam anxiety sound familiar, you're not alone! D. Therefore, people need an appropriate amount of pressure to help deal with exams. E. Realizing time is almost up and that there's still a lot of blank space will make you desperate. F. However, if you are overly anxious about the result, you may be unable to focus on your work. G. After you get the paper, dive right in by getting some questions done to build up your confidence. III. 完形填空 Rebecka Peterson, a high school math teacher, is the 2023 National Teacher of the Year. Her first year of teaching wasn't without ___1___, but she remembered why she was there and wanted to bear those ___2___ thoughts in mind. So she created the One Good Thing blog. It was ___4___ and fun, really. Every evening, she would write in her blog, ___5___ one good thing she experienced that day. She gave her blog the tagline: "Every day may not be good, but there is one good thing every day." She encouraged her ___6___ to do the same in their handwritten journals. Just a few minutes a day to ___7___ something good that happened—that would be enough, "she ___8___. She believes that it will make them happier and more ___9___ about learning. During her eleven years of teaching, Peterson has ___10___ that some students find math difficult. Her efforts to make it ___11___ to the students made her the 2023 Oklahoma Teacher of the Year. From there, she ___12___ the title of "2023 National Teacher of the Year" for her remarkable contributions to maths education. Peterson has travelled around the country, talking to other teachers about bringing ___13___ back into classrooms. Her goals include emphasizing the positive experiences students have not only of math but of learning ___14___. She hopes her stories will attract new teachers to the profession and give ___15___ to current ones. 1. A. difficulties B. wonders C. rewards D. surprises 2.
