I took a deep dive into the publicly available TOEFL reading sets to measure which academic subjects appear most frequently.  My study included the tests in:

• The Official Guide to the TOEFL 
• The Official iBT Tests Vol. 1
• The Official iBT Tests Vol. 2
• The free practice test on ETS.org
• The TOEFL PDF sets on ETS.org
• The Propell Workshop Teacher’s Book

These contain 47 passages in total.

I think this is everything that is easily accessible.  I didn’t include the TPO sets in my study because we aren’t really supposed to have access to those.  If there are any other sources I should consult please let me know, and I will add them to the list.

I examined each reading passage and classified it by subject.  I focused on the broadest possible subject headings.  So, for example, I used “history” as a category but not “political history.”  This wasn’t always an easy task as some of the passages cover overlapping subject areas.

Following this chart, I’ll include a few notes about more specific subject areas.

Anyways, here’s what I found:

As you can see, history is by far the most common subject area in the reading section.  Zoology is also pretty common.  

There are a few other things that are worth mentioning here.  They are:

• The passages about history often focus on the history of early humans and early civilizations.  
• Political history is also somewhat common.
• One of the passages marked as “geology” was actually about the history of geology.
• Likewise, the passage about astronomy was about the history of astronomy.  Read some history!

Perhaps this information will serve as a guide you as look for materials to develop your academic reading skills before the test.

Hey, it’s the end of the month, which means it is time for some recommended reading.

I spent some time catching up with my National Geographic subscription. Honestly, it has been a tough year for Nat Geo, as they’ve attempted to pivot into being something of a current events magazine. They haven’t always been successful at that, but there are usually a few good items in every issue. Here’s what I liked from the December thru February issues:

• So Great, So Fragile  is a long article about threats to the Great Lakes in North America.  It is really long, but still worth your time as physical geography is a common topic on the reading section of the test.
• Reclaiming History is a long article about the desire to remove symbols of the Confederate States of America from the USA.  This is a great example of how the magazine is succeeding in its coverage of current events.  Of course it touches on  history quite a lot, which is another common topic on the TOEFL.

As usual, I read a few issues of “Science News.”  As always, everything in this magazine is useful.  A few things caught my eye, though.  They are:

• Rats with Poison Hairdos Show a Cuddly Side is another weird animal story.  These rats chew on poisonous tree bark and droll it all over their bodies to protect themselves from predators.  Zoology is a common topic on the reading section of the test, so I always recommend articles about animals.  Actually, keep an eye on the blog for a “research report” on the most common subject areas.  I’ve got the numbers and will post them soon!
• Ice Age Hunters’ Leftovers May have Fueled Dog Domestication is a very short article that I found particularly interesting.  Apparently early humans had too much protein in their food supplies.  Like, they had so much meat that was free of fat that they couldn’t eat it all.  They gave it to wolves and, presto, the domesticated dog was born.  A lot of TOEFL reading passages deal with early humans, so check this one out.
• Early Sea Trip was Probably No Accident also covers early humans.  This one is about how ancient mariners first reached Japan’s Ryukyu Islands.

Alright, so those are your articles for the month.  I also read a few books, for what it’s worth.  A few are worth mentioning:

• I read “Gigged” by Sarah Kessler.  It’s a book about the “gig economy,” which is dominated by companies like Uber.  Economics doesn’t seem to be a particularly common topic on the TOEFL, but all non-fiction has some value when it comes to improving your academic reading skills.  This is a fairly easy read, and it feels something like an extended magazine article.  No free versions are available online, but you can get it via Amazon.
• I also read Colin Thubron’s “Mirror to  Damascus.”  This is a hard book.  But if you are interested in history and travel take a moment to check out a free version on Open Library.  Thubron is, in my opinion, the best living travel writer. This year I will be revisiting a bunch of his travelogues in preparation for his latest book, which will be published in a few months.  “Mirror to Damascus” is his very first book, written after he took a trip to Syria in his early twenties.  I also visited Syria in my early twenties (but 40 years after Thubron).  His book makes me feel some guilt for just mucking about when I was in the country, but I do remember my time there fondly.  It was one of the happiest months of my life.

That’s all for now, but I’ll have a few more recommendations next month.  Stay tuned.
