IMPROVE YOUR WRITING | WRITING INSPIRATION | GET PUBLISHED RESOURCES

Founded in 1887, The Writer aims to expand and support the work of professional writers with a straightforward presentation of industry information, writing instruction and professional and personal motivation. If you’re passionate about books, authors, and writing, you’ll find everything you need within our pages 12 times a year.

Our editors are interested in query letters (投稿信) on concrete topics written by emerging and experienced writers. We are looking for clear takeaway for our readers: What can they learn to improve their writing or advance their careers? What specific how-to tips and strategies will accomplish this?

In addition to a fleshed-out outline of your story idea and an estimated word count, queries should include a brief description of your background. For personal essays, we prefer writers to attach or paste the finished piece in their query email. We do not accept material that has been previously published in any form in print or online.

Queries should be sent by e-mail to tweditorial@madavor.com. All queries sent to any other address will be deleted.

Unfortunately, we receive hundreds of letters every week and cannot respond to all of them. If you haven’t heard from us in two weeks, please feel free to move your submission (投稿) to another publication. If you’re unfamiliar with our magazine, we recommend reading a few issues, subscribing, or at least signing up for our newsletter to get a feel for the kind of work we publish.

Article lengths vary widely from 300 to 3,000 words.

We recommend writers ask themselves the following questions before querying. It isn’t necessary to include them in your query, but we find it’s a good way to help us understand how your piece best fits in our pages:

* How specifically will this story idea help our readers become more informed writers?

* Why is this particular idea timely or relevant?

* Why are you the perfect person to write this piece?

We prefer electronic queries. Please do not mail queries.

Payment varies.

Thank you for considering a submission to The Writer magazine, the voice of imagination, creation, and publication since 1887.

To many of us, the bilateral symmetry(左右对称) that characterizes the human face and the animal kingdom may be one of the first impressions we get of the world. If you reflect the left half of the face or body in a mirror, you obtain something that closely 1 the right half. Bilateral symmetry is so common that it could 2 be due to chance. If you think of the human body as a collection of some ten thousand trillion molecules, then there are countless ways to combine them into non-symmetrical shapes than into symmetrical ones. Why is it, then, that bilateral symmetry is so common? Given that all life on Earth slowly 3 through natural selection, the fact that we and many animals possess left-right symmetry, not, say, up-down or front-back symmetry, must have somehow 4 certain advantages. But how?

We can understand at least some parts of this natural “engineering” 5 by considering some simple physical principles. First, on the surface of the Earth, the Earth’s gravity introduces a 6 difference between up and down. Animals had to be able to remain stable and to cope with their weight under Earth’s perpetual downward pull. The ability to move further enhanced the difference between top and bottom.On one hand, birds had to handle the aerodynamics of flying, and on the other, be able to handle landing. Land animals had to develop some “mechanical” appendages (in other words, legs) to allow them to 7 themselves efficiently.

Animal locomotion was probably also 8 for the front-back asymmetry. Whether it was a bird, or a fish, having the sensory organs and the mouth in the front could mean the difference between finding lunch or missing it. The digestive and reproductive systems were pushed to the rear. Having eyes, ears, and noses in the front was also 9 for the avoidance of predators, and for the ability to explore an area before actually entering it. Life 10 that are fixed in one place or that move very slowly, such as trees or jellyfish, tend to have a different kind of symmetry, similar to that of a cone(球果) — they produce similar reflections in any mirror passing through their central axis.
