语言准确性是培养学生英语学科核心素养的基础。这些年的大中小学教育改革使部分师生误以为语言准确性不再重要，甚至忘记了自己教和学的是“语言”本身，其后果是学生们的口笔头表达错误百出，惨不忍闻/睹，师生们对教与学的成效都深感挫败！

今天我们来分享一些不会增加教师工作负担和学生学习负担但能提升学生语言准确性的练习设计。类似练习适用于初中、高中和大学本科的英语学习。

下文选自外研社普通高中教科书《英语》选择性必修第一册（2019）第一篇阅读文本。 

The Best Medicine

As I approach the hospital wearing my white coat, I look just like any other doctor. That is until I put on my curly rainbow wig, big red nose, and add my name badge “Doctor Larry Laugh-Out-Loud”. I walk through the doors into the waiting area, where there’s a familiar atmosphere of boredom and tension. People sit uncomfortably on plastic chairs, looking through old magazines, all of which have been read hundreds of times previously. Anxious parents do what they can to comfort nervous and crying children.

In the middle of this particular scene I spot a small girl whose ankle is twice its normal size. I speak with the on-duty nurse, who tells me that Lara’s parents rushed her to the hospital after she fell off her bicycle. Since getting here, Lara has spent her time crying in pain. Although it’s the doctors and nurses who will treat her injury, it’s my job to make her feel better.

Scientific studies show that laughter produces chemicals to make people feel better, which means clown doctors can be helpful. We are specially trained clowns who work as part of a programme known as “hospital clowning”. I chose this career because of my experience of going to hospital when I was a kid. Although the doctors and nurses did a great job, hospitals weren’t really designed for children. I spent much of the time when I was there feeling frightened and more than a little bored! Being a clown doctor means I can help people by entertaining them.

Visiting hospitals and other health care facilities, we clown doctors work together with medical professionals. On a typical day, we spend our time cheering up patients, their families, and more often than not, the hospital staff, too! We do this by doing magic tricks singing songs, telling stories and, of course, telling silly jokes. Some children, though, don’t feel like laughing, especially if they’re in pain. We have to be very sensitive and work closely with the doctors and nurses, who keep us updated on each patient.

And my magic medicine does indeed seem to do the trick. While the doctor concentrates on examining Lara’s ankle, I get her attention by doing a magic trick. Although she is clearly still in some pain, her scared and anxious look has been replaced – first by a small smile, and then by loud laughter as I “magically” produce her sock from out of my pocket. Seeing their daughter so much happier has in turn made Lara’s parents more relaxed.

And as for me? Well, when I take off my wig and my red nose, I’m still wearing a big smile, as I remember all the fun and laughter of the day. While there might be more hospital visits ahead for Lara and others, I hope that clown doctors help make it a friendlier place to visit. After all, it really is true that “laughter is the best medicine.” (494 words)
