Gerunds and Infinitives

 There are certain  words in English that are usually followed by an infinitive or a gerund. When these  words are followed by an infinitive, this could be with or without to. Gerunds are form adding -ing to the base form.

To know you is to love you.

She made her swim.

Cycling is good for your health.

Before going to bed he turned of the light.

Some verbs can be followed by a gerund or by an infinitive with no difference in meaning.

Begin, like, continue, love, hate, prefer, intend and start.

I started to read. = I started reading.

The musculoskeletal System

 

Did you know you have more than 600 muscles in your body? They do everything from pumping blood throughout your body to helping you lift your heavy backpack. 

You control some of your muscles, while others — like your heart — do their jobs without you thinking about them at all.

Muscles are all made of the same material, a type of elastic tissue (sort of like the material in a rubber band). Thousands, or even tens of thousands, of small fibers make up each muscle.

You have three different types of muscles in your body: smooth muscle, cardiac muscle, and skeletal muscle.

Plate Tectonics Theory

The theory, or idea, of plate tectonics says that Earth’s outer layer is made up of large, moving pieces called plates. 

German meteorologist Alfred Wegener is often credited as the first to develop a theory of plate tectonics, in the form of continental drift. 

Bringing together a large mass of geologic and paleontological data, Wegener postulated that throughout most of geologic time there was only one continent, which he called Pangea, and the breakup of this continent heralded Earth’s current continental configuration as the continent-sized parts began to move away from one another. 

Scientists discovered later that Pangea fragmented early in the Jurassic Period. Wegener presented the idea of continental drift and some of the supporting evidence in a lecture in 1912, followed by his major published work, The Origin of Continents and Oceans (1915).

All of Earth’s land and water sit on these plates. The plates are made of solid rock. Under the plates is a weaker layer of partially melted rock. The plates are constantly moving over this weaker layer.
