Several Eye-Opening Facts about Tears

Crying can be good for you.Some studies have shown a good cry can cause the release of certain chemicals that make us feel better.Crying can also improve people's sense of well being by bringing about social support.On the other hand,crying can sometimes make you feel worse than if you haven't cried at all.One study found that people who tend to cry in general more often feel worse after crying during a movie than people who seldom cry.
According to Entertainment Weekly,the biggest Hollywood tearjerker of all time is Terms of Endearment,about how a family deals with a cancer diagnosis.Number 2:Bambi.According to Merriam-Webster,the term tearjerker first appeared in 1912,which happens to be the same year the Titanic sank.(The movie Titanic is 16th on EW' s tearjerker list.)
In medieval(中世纪)times,crying was perfectly acceptable,even manly.In the Anglo-Saxon poem Beowulf,when Beowulf was killed by a dragon,his soldiers were extremely sad and cried aloud for his death.King Arthur was also known to turn on the waterworks.
Speaking of war,tear gas was banned on the battlefield via the Chemical Weapons Convention of 1993,which was made to happen by Iraq's use of chemical weapons in Iran in the 1980s.That said,American police can still legally use tear gas for crowd control.

''They're made out of meat. ''
''Meat? ''
''There's no doubt about it. We picked up several from different parts of the planet, took them aboard our craft, and probed them all the way through. They're completely meat.''
''That's impossible. What about the radio signals? The message to the stars? ''
''They used the radio waves to talk, but the signals don't come from them. The signals come from machines. ''
''So who made the machines? That's who we want to contact. ''
''They made the machines. That's what I'm trying to tell you. Meat made the machines. ''

''No. They're born meat and they die meat. We studied them for several of their life spans, which didn't take long. Do you have any idea what's the life span of meat? ''
''Spare me. Okay, maybe they're only part meat. You know, like the Weddilei. A meat head with an electron plasma(电浆) brain inside. ''
''No. We thought of that, since they do have meat heads, like the Weddilei. But I told you, we probed them. They're meat all the way through. ''
''No brain? So. . . what does the thinking? ''
''You're not understanding, are you? You're refusing to deal with what I'm telling you. The brain does the thinking. The meat. ''
''Oh, my! So what does this meat have in mind? ''
''First it wants to talk to us. Then I imagine it wants to explore the Universe, contact other creatures, exchange ideas and information. The usual. ''
''We're supposed to talk to meat! ? ''
''That's the idea. That's the message they're sending out by radio. 'Hello. Anyone out there? Anybody home? ' That sort of thing. ''
''They actually do talk, then. They use words, ideas, concepts? ''
''They do, but what do you think is on the radio? Meat sounds. They can even sing by forcing out air through their meat. ''

Facts About Goal Setting
These practical tips on goal setting can help make it easier to set and reach goals:
Specific, realistic goals work best. __1._____ "I'm going to recycle all my plastic bottles, soda cans, and magazines" is a much more doable goal than "I'm going to do more for the environment." And that makes it easier to stick with.
_____2._____ It will probably take a couple of months before any changes — like getting up half an hour early to exercise — become a routine part of your life. That's because your brain needs time to get used to the idea that this new thing you're doing is part of your regular routine.
____3.______ Say your goal out loud each morning to remind yourself of what you want and what you're working for. Writing it down works too. Every time you remind yourself of your goal, you're training your brain to make it happen.
____4._______ The key to making any change is to find the desire within yourself — you have to do it because you want it, not because a girlfriend, boyfriend, coach, parent, or someone else wants you to. It will be harder to stay on track and motivated if you're doing something out of obligation to another person.
Roadblocks don't mean failure. Slip-ups are actually part of the learning process as you retrain your brain into a new way of thinking. It may take a few tries to reach a goal. But that's OK — it's normal to mess up or give up a few times when trying to make a change. So remember that everyone slips up and don't beat yourself up about it. ___5.___
A. Repeating a goal makes it stick.
B. Pleasing other people doesn't work.
C. You should make a change in your life.
D. Just remind yourself to get back on track.
E. Set a goal and come up with steps to reach it.
F. It takes time for a change to become an established habit.
G. When it comes to making a change, the people who succeed are those who set proper goals.

Have you ever thought about what you would like to do after school? Perhaps one of these rather different jobs will suit you.
TASTER: Food companies need people to taste the products that they are making. So many kinds of no bad-tasting food are put onto the supermarket shelves. All tasters do all day is take small bites of food. They make notes of what tastes good and what tastes bad. It is not a job for those who would like to stay thin.
SNAKE MILKER: This involves taking the poison out of a snake’s teeth. You hold the snake over a glass and make it open its mouth very wide. The poison will then drip from the back of the teeth into the glass; this is known as milking the snake. You have to be very brave if you want to try this.
GOLF BALL HUNTER: You will spend your day diving into waterholes at different golf courses to hunt for lost golf balls. You could be picking up as many as 5,000 balls a day. Many golfers are willing to buy used golf balls and you could be making a lot of money.
CLOCK CLEANER: Every day you will be climbing to the top of the clock towers in the city. Your responsibilities will be to oil, wind and repair the clocks. This is not a job for someone who is afraid of heights.
1.If you are a taster, you will ________.
A. pick up golf balls B. oil and repair the clocks

A successful scientist is generally a good observer. He makes full 36 of the facts he observes. He doesn’t accept ideas which are not 37 on obvious facts, and therefore refuses to accept authority as the only 38 for truth. He always 39 ideas carefully and makes experiments to prove them.
The rise of 40 science may perhaps be considered to 41 as far back as the 42 of Roger Bacon, the wonderful philosopher of Oxford, who live 43 the years 1214 and 1292. He was probably the first in the Middle 44 to suggest that we must learn science 45 observing and experimenting on the things around us, and he himself 46 many important discoveries.
Galileo, however, who lived more than 300 years later (1564-1642), was the greatest of several great men, 47 in Italy, France, Germany, or England, began by 48 to show how many important 49 could be discovered by observation. Before Galileo, learned men believed that large bodies fell more 50 towards the earth than small ones, 51 Aristotle said so. But Galileo, going to the 52 of the leaning Tower of Pisa, let fall two 53 stones and proved Aristotle was wrong. It was Galileo’s 54 of going direct to Nature, and proving our 55 and theories by experiment, that has led to all the discoveries of modern science.

Facts about fevers
You wake up one morning, and your head feels like burning. Right away, you think, “Oh, no! I have a fever!” However, when you take your temperature, you see that it's only 37.2.1. Or, do you? From the standards in use for a long time, a fever starts at 38. Some doctors now don't agree with that, though. 2.It's the same for normal body temperatures.
They argue that everyone's normal body temperature isn't 37℃. It's 36.6 to 38℃ for kids and 36.1 to 37.2℃ for adults.3. Besides, people's body temperatures don't stay the same all the time.
When your body temperature is around 38℃, you have a fever.4.Fevers show that the body is doing its job. It's fighting the bad viruses and bacteria in your body. The body attacks them by turning up the heat. That way, it's harder for the viruses and bacteria to make copies of themselves. When their numbers decrease, the fever does, too.
5.So, let them do their jobs and don't treat them. Instead, try to find the cause and treat that. If the fever reaches 39.4C or higher, call your doctor. Do the same if the fever lasts longer than three days. Fevers fight to protect us, so they're our friends, not our enemies.
A.It means you have a fever.
B.Mild fevers don't last long.
C.So, you don't have a fever.
D.Fever does great harm to your body.
E.Women also have a higher number than men.
F.Many people think it's a bad thing, but it's not.
G.They feel our ideas about fevers are wrong and too old.
