Dear Ranger Jack, Q: Do crows always look angry? A: Crows are emotional animals. They can show
happiness, anger and sadness. Besides this, crows have excellent memories.
The Animal Whisperer Q: Are crows solitary animals? A: Many types of crows are *solitary.
But they will come together in groups when it is time to *forage.
Q: Are crows really intelligent? A: Crows have the biggest brain to body
ratio among birds. Crows know how to get food by using tools. They know to leave hard nuts on the road to let passing cars break them open.
Q: Can we keep crows as pets? A: Crows are very social and can
form a bond with humans. But birds should fly freely in the sky. There is no reason we should keep birds in cages. *forage: search for food *solitary: living alone or in pairs

Understanding
Taros Taros come in about a hundred different varieties. They can be oval or round in shape.
Taro plants have broad leaves that are shaped like a palm.
Taros are adaptable to a wide range of soils. Their roots have weak absorption, so plenty of water is needed throughout their growth period.

Oh! I See When most somnambulists (sleepwalkers) wake up, they have no idea of what they were doing during their night-time sleepwalking episodes.
SAS L1 no. 41
21
Somnambulism can be caused by mental stress such as anxiety, fear and tension. Specialists believe that somnambulism may also run in families.
The sphere of a somnambulist’s activities is always the environment that the somnambulist is most familiar with, or the things they do often in the daytime.
Somnambulists can perform complicated tasks in their sleepwalking episodes. They can even navigate obstacles and are often not hurt if they bump into the obstacles. SAS L1 no. 41

*contrails: a trail of condensed water that looks like a white streak
34
w! Wo
w! Wo Let’s take a ride in my jet plane.
I’ll get closer so you can see the “white smoke”.
The “white smoke” is actually formed by lots of water droplets.
When the exhaust emitted from the plane mixes with the air, it condenses into many water droplets.
When the water droplets come together, they form a cloud that is called a contrail.
Oh! I See A contrail is generally one to two kilometres thick.
SAS L1 no. 41

I’d love to open the window and touch this contrail.
I see. We really can’t see any of these water droplets at a distance.

SAS L1 no. 41
*fuselages: the main body of aircraft
37
Generally, jet airplanes can produce contrails at altitudes from 7,000 to 10,000 metres. Contrails are difficult to form anywhere beyond this range. Most contrails don’t exist for too long and usually disappear quickly. However, some contrails can exist for over an hour, if conditions are favourable, and expand into wider clouds.
When aircraft are performing at an air show, they leave colourful, beautiful and different-shaped smoke trails. These smoke trails are not contrails, but smoke agents made of chemicals and pigments.

Antelope Canyon was formed after soft sandstone was eroded over millions of years. Mainly it was flash flood erosion followed by wind erosion.
The geological structure of Antelope Canyon is red sandstone. The colour of the sun’s rays changes more constantly in deeper parts of the canyon. The sandstone can appear orange, purple and red. Tourists can go in only when they are led by native Navajo tour guides. This is for the protection of natural and cultural heritage, and also for the safety of the tourists.

g!
Ouch! I didn’t see that rock!
I’d wish I could shave off all my long hair.
Try putting your *bangs like this and you won’t have to worry about bumping into anything!
You can’t do that! Our long hair is one of our features.
Oh! Thanks!

The yak is a *herbivore that lives in extremely cold areas. It is a cattle breed that lives in the highest place above sea level in the world. The long hair on the yak keeps it warm, which helps it survive in extremely cold conditions.
Yaks are good at walking on dangerous roads, snowy mountains and in swamps. They are mainly distributed in China’s Qinghai-Tibet plateau in places that are 3,000 metres above sea level. Local *herdsmen, merchants and mountain climbers often use yaks to carry their heavy stuff.
