1. Read, read, and read The more you read -- especially novels and literary works, but also magazines and newspapers -- the more words you'll be exposed to. As you read and uncover new words, use a combination of attempting to derive meaning from the context of the sentence as well as from looking up the definition in a dictionary. 2. Keep a dictionary and thesaurus handy. Use whatever versions you prefer -- in print, software, or online. When you uncover a new word, look it up in the dictionary to get both its pronunciation and its meaning(s). Next, go to the thesaurus and find similar words and phrases -- and their opposites (synonyms and antonyms, respectively) -- and learn the nuances among the words. 3. Use a journal. It's a good idea to keep a running list of the new words you discover so that you can refer back to the list and slowly build them into your everyday vocabulary. Plus, keeping a journal of all your new words can provide positive reinforcement for learni...

Turkeys. No, seriously. Because they’re so popular for Thanksgiving, farmers have been breeding male turkeys to become fatter and fatter. This causes them to lose the ability to reproduce. Well, to be more specific, they still have the ability to reproduce. However, they become so fat that they actually physically can’t breed. Don’t believe me? Let me show you… This: is a wild turkey. Now let’s look at those fat Thanksgiving turkeys: Woah! I can’t belive what Farmer John will do for money.

There are historical and modern reasons: Gold is non-reactive with other chemicals so it retains its color. Yet silver blackens, which has undesired effects. Gold has a unique color unlike other metals do. So people are fond of it and this has created more demand for it. Gold is rarer than silver and this is the main reason. When there is less supply of something and higher demand on it, then the price will be higher. Also because there are a lot more silver than gold on earth. On average, silver exists at a 17:1 ratio versus gold in the Earth’s crust.

Ethiopia for its long history is surrounded by mountains, and the only country that its geographical location possess total problem for other conquerors. Ethiopia has very harsh weather when you found surprisingly in the Horn of Africa, and Africa, you know, mostly no snow. But in Ethiopia, you won’t dare to fight in such 50 Celcius degrees. But at night or winter, it can be -15 Celcius degrees. Ethiopia has many different and hidden caves people have never explored itself.

You don’t know if any Ethiopians would surprisingly shoot you from back. Ethiopia also sustains a very gallant and, also, strong military force througho...
