Also after initials, as in Alfred D. Smith. Every sentence contains at least one punctuation mark -- the one at its end. The most common of these sentence-ending punctuation marks is the period (".", also called a "full stop"). This simple dot is used to mark the end of a sentence that is declarative. Most sentences are declarative. Any sentence that states a fact or describes or explains an idea is declarative. Here is an example of a period (full stop) being used correctly at the end of a sentence:The accessibility of the computer has increased tremendously over the past several years. The question mark ( "?" ) used at the end of a sentence denotes an interrogative sentence -- basically, a question. Use this punctuation mark at the end of any question, query, or inquiry. Here is an example of a question mark being used correctly at the end of a sentence:What has humanity done about the growing concern regarding global warming? The exclamation point ("!", also called an "exclamation mark" or "shout mark") suggests excitement or strong emphasis. The exclamation point is used to end exclamations -- short expressions of intense emotion that are often only one word long. Here are two examples of an exclamation point being used correctly at the end of a sentence:I can't believe how difficult the exam was! Eek! You scared me!

Summary: Use a period (full stop) to end declarative sentences and statements. Use a question mark to end questions. Use an exclamation point to end exclamatory sentences.

Unlike other pulley machines, the one you'll use for crossovers allows you to set weights for each side separately. Set them both to the same weight, and make sure that the cable pulleys are set in a low position as near to the floor as possible. Some cable machines have different grip attachments that can be attached. For cable crossovers, make sure to attach the single-grip cable attachments on either side.

Summary: Attach the desired amount of weight to each side of a dual pulley machine.

Definitely pay attention when you're in the same room as him to see if he keeps glancing your way. If you start to notice that he stares at you on a daily basis, and if you don't have anything weird stuck in your teeth, this could be a sign that he is into you. If you catch him looking at you and he quickly looks away, that means he was definitely looking at you and not just in your general area. If you want to flirt with him, try smiling and giving him a quick wave the next time you see him staring in your direction. This is a step above just catching him staring at you. If he makes direct eye contact with you when you pass in the hallway and gives you a smile, he is definitely noticing you and interested in being friendly. In this type of situation, think about what kind of guy he is in general. Do you notice him flirting with lots of people? Or is he generally shy? If he is a flirt, he may be interested in you, but pay attention to his actions to find out for sure! Whether he is talking directly to you or to a group of his friends, look at him to see if he is checking out your response to his stories or jokes. If he glances your way to see how you're responding, this means he cares that you notice him. If he tries to make you laugh and seems happy when you do, that's another sign he may like you. This won't be true with all guys, but it's a fairly common thing that happens. If he likes you, he may get tongue-tied, trip, knock things over, or just seem a bit clumsier than usual when he gets near you. If he drops his books or knocks something off if his desk when you walk by, he may like you. Think about how you act when you get close to your crush. Chances are, this guy experiences really similar feelings when he's around someone (maybe you!) that he likes. Physical touch is a huge indicator of attraction. Does he tap your shoulder or place his hand on your arm to get your attention? If you're talking, does he reach over and make physical contact? Does he try to sit beside you in class or on the bus?
Summary: Pay attention to how often he looks at you in class or in the hallway. See if he smiles at you and makes eye contact when you're nearby. Wait to see if he watches your reaction when he makes jokes in class. Keep an eye out for tripping or other clumsy behavior. Observe if he touches your arm in class to get your attention.
