Monkeys are clever, social animals. They are known for running and leaping through trees with ease. Like apes and humans, monkeys belong to the group of mammals called primates.
Monkeys look somewhat like apes such as chimpanzees, orangutans, and gorillas. But monkeys differ from apes in several ways. For instance, every monkey has a tail, even if it is just a tiny nub. Apes do not have tails. Monkeys also generally have narrower chests than apes do.
Monkeys are intelligent animals that are good at solving problems. Almost all types live together in groups. A monkey group commonly includes several related females, their young, and one or more males.
Most monkeys eat mainly plants. Different types eat fruits, flowers, seeds, shoots, roots, and leaves. Some types of monkey also eat birds’ eggs, insects, and other small animals.

Probably, every woman dreams of her own knight on a white horse, who will come and take her to a fairy tale, in which he will Serenade her, kiss her hands and generally perform various feats in her honor. This is in our view the standard of a knight without fear and reproach.
Knights in our understanding are closely connected with the middle ages, it is from there that the ringing of swords and the trampling of hot horses from famous jousting tournaments are heard.
The middle ages are shrouded in a cloak of romance and hidden from us under the visor of time.
Knights appeared in Europe around the time of 10 in the 19th century, they were the personal cavalry army of a separate feudal Lord or king, in fact, they were the equestrian bodyguards of their master.

various feats - различные подвиги
reproach - упрек
trampling - топот
jousting tournaments - рыцарские турниры
shrouded - окутанный
cloak - плащ, мантия
cavalry army - кавалерийская армия

A sore throat is pain, scratchiness or irritation of the throat that often worsens when you swallow. The most common cause of a sore throat (pharyngitis) is a viral infection, such as a cold or the flu. A sore throat caused by a virus resolves on its own.
Strep throat (streptococcal infection), a less common type of sore throat caused by bacteria, requires treatment with antibiotics to prevent complications. Other less common causes of sore throat might require more complex treatment.
The best way to prevent sore throats is to avoid the germs that cause them and practice good hygiene.
- Wash your hands thoroughly and frequently for at least 20 seconds.
- Avoid touching your face. 
- Cough or sneeze into a tissue and throw it away, and then wash your hands.

scratchiness - царапанье
viral infection - вирусная инфекция
strep - стрептококк
complications - осложнения
prevent - предотвращать
hygiene - гигиена

Ancient Egypt and India used tattoos as methods of healing and as methods of religious worship. They were also marks of a status in a society but also a punishment. Tattoos in Philippines were marks of the rank and accomplishments and people there believed that they have magical properties.
When Christianity appeared, tattooing was considered a barbaric tradition and it slowly faded in Europe to return with transoceanic travels in 16th. At first, tattooing was “reserved” for sailors and lower classes but in time, as tattoo artists became more and more proficient, tattooing became hobby of aristocracy which had money to pay high prices of professionals. As the tattooing became cheaper it again was seen as a mark of a lower class. 

healing - исцеление
worship - поклонение
accomplishments - достоинства

Backpacking is a very loose definition. There are backpackers who go tramping in the forests sleeping in tents and on the beach, and hitchhike their way around the world.
And there are those who backpack with roller-bag suitcases, sleep in hotels and rent a car to get around a country.
These are two completely different types of traveling, but they both like to call themselves backpackers.
A backpacker is a person who is taking a vacation or traveling for whatever reason but instead of carrying a suitcase and luggage, is carrying everything in a backpack. They are likely someone who would be staying in a hostel rather than in a hotel. They will be more likely to take public transportation and walk than to rent a car.
Backpacking is considered to be an inexpensive way of traveling.

loose - обширный
tramping - бродить
hitchhike - путешествовать автостопом
roller-bag suitcases - чемоданы на роликах
vacation - отпуск
considered - считается
inexpensive - недорогой

Without light, there is no color. When people see colors, they are really seeing different types of light bouncing off objects.
Three colors of light—red, blue, and green—can combine to make any other color. For example, if a beam of green light shines over a beam of red light, yellow light appears. Red, blue, and green are called primary colors of light. Mixtures of the primary colors of light produce all the other colors.
Cells in the eyes called cones make it possible for humans to see color. Different types of cones absorb different colors. Some people are color blind. This does not necessarily mean that they cannot see any color at all. More commonly, people with color blindness think certain colors, such as red and green, look the same.

bouncing off - отскакивая от
combine - соединять, объединять

The marine animals known as sea urchins look something like globe-shaped pincushions. There are more than 900 species, or types, of sea urchin. They live in all seas except those of the polar regions. They are found on the ocean floor, usually on hard surfaces.
Sea urchins mainly eat plant material. The mouth contains a strong jaw piece called Aristotle’s lantern, which is made up of five bony teeth. The teeth can be pushed out of the mouth to scrape algae and other substances off rocks.
Sea urchin eggs are prized food in some countries. Sushi and seafood recipes often contain sea urchins. Many of the sea urchins caught in the United States are sent to Japan. Some conservation groups monitor the catching of sea urchins to make sure that enough of the creatures remain in the water to reproduce.

Everyone experiences stress to some degree. The way you respond to stress, however, makes a big difference to your overall well-being.
Stress can sometimes be mistaken for anxiety, and experiencing a great deal of stress can contribute to feelings of anxiety. Experiencing anxiety can make it more difficult to cope with stress and may contribute to other health issues, including increased depression, susceptibility to illness, and digestive problems.
Stress and anxiety contribute to nervousness, poor sleep, high blood pressure, muscle tension, and excess worry. In most cases, stress is caused by external events, while anxiety is caused by your internal reaction to stress. Stress may go away once the threat or the situation resolves, whereas anxiety may persist even after the original stressor is gone.

anxiety - беспокойство
contribute - способствовать
susceptibility - восприимчивость
digestive - пищеварительный
nervousness - нервозность
muscle tension - мышечное напряжение
resolve - решать

A map is a symbolic representation of selected characteristics of a place, usually drawn on a flat surface. Maps present information about the world in a simple, visual way. They teach about the world by showing sizes and shapes of countries, locations of features, and distances between places. Maps can show distributions of things over Earth, such as settlement patterns. They can show exact locations of houses and streets in a city neighborhood.
Mapmakers, called cartographers, create maps for many different purposes. Vacationers use road maps to plot routes for their trips. Meteorologists—scientists who study weather—use weather maps to prepare forecasts. City planners decide where to put hospitals and parks with the help of maps that show land features and how the land is currently being used.

representation - представление
features - особенности
distributions - распределения
settlement patterns - схемы расселения

Over 200 years ago, when locomotives were first being developed, people worried their speed would make passengers “unable to breath” or that “they would be shaken unconscious by the vibrations.”
Clearly, trains have changed dramatically since they first took to the rails. Like any other mode of transportation, trains, as we know them today, have been centuries in the making!
Today, it’s relatively simple to purchase a train ticket and travel freely—depending on what part of the world you’re in.
Railways existed as early as 1550, in Germany. These pathways of wooden rails called “wagonways” were the beginning of modern rail transport, making it easier for horse-drawn wagons or carts to move along dirt roads.
By the late 1700s, iron replaced the wooden rails and wheels as wagonways evolved into “tramways” and became popular throughout Europe.

unable - не в состоянии
unconscious - без сознания
dramatically - резко, сильно

Since the beginning of civilization, humans have needed to maximize the usefulness of water resources and minimize destruction from floods and drought. To this end, dams have been used for millennia, providing storage for drinking water and irrigation, flood control, and open water for navigation and recreation as well as improving water quality and generating electricity.
While dams are essential components of our infrastructure systems, they also present potential hazards. The mass and potential energy of the water impounded by a dam can be devastatingly destructive if the dam were to fail and the water were to be released uncontrolled.
When properly constructed, designed, and maintained, dams pose a very low risk of failure. Poor design, neglect, and catastrophic natural events such as massive rainstorms or earthquakes can cause dams to fail.

irrigation - орошение
