We all know that exercise is great for you. But let's be honest.1. Here I am going to share my top reasons for working out.
Exercise can completely change your feeling. When you work out, your body produces endorphins（内啡肽）.2.You will feel better after a workout than you did before it. Next time you're having a bad day, try going for a fast-paced run or taking a spinning class（单车课 程），and the day won't seem so bad after all.
3. Whenever I move to a new city or work, I look for exercise classes, where you can always meet like-minded people. You can support each other during a difficult workout. And you all share a collective feeling of happiness when the hard class finishes!
Exercise makes you feel confident. We all know the physical effects of exercise on our bodies but we don't always talk about the mental effects.4.This new feeling might even help in your work or social life.
Exercise makes you feel strong and fit. Running 30 minutes every day helps you keep healthy and makes you feel a sense of achievement. It's a great feeling doing something you couldn't do before and knowing it's a result of your hard work.
So, next time you're feeling down, put your trainers on and get sweating. It might not be easy in the beginning for most people. 5.
A.Exercise helps you become sociable.
B.Exercise helps you reduce stress and anxiety.
C.That will give you a rush of happiness.
D.You can get to know each other well and make close friends.
E.But I promise you will feel much better once you've finished.
F.Sometimes finding that motivation to work out can be a little difficult.
G.Exercise might give you belief in yourself from being comfortable with your body and appearance.

We all know that water is tasteless. But it happens from time to time: you pick up the bottle of water you didn’t finish yesterday, and it tastes strange. Most often, you tend to drop the bottle in the trash bin, believing that the water has gone bad. But is it true?
According to Time, of course not, taste has little to do with quality of water.
According to Time, when water is exposed to the air for 12 hours, carbon dioxide interacts with the H2O in the water, and the pH value lowers slightly. As a result, the water has a different taste.
“But it’s most likely safe to drink,” Norwegian expert Truls Krogh told Science Nordic. “If the water is covered and of good quality to start with, in principle it can last a thousand years. That’s because when water is fresh, it contains little organic matter. As long as water is held in clean glasses or bottles, no pollutants will enter it to harm our health.”
People in countries like the US, the UK and Australia usually drink tap water. According to Time, if tap water is drunk within six months, the chlorine (氯气) in the water will be enough to kill any bacteria and keep it safe to drink.
However, there are also some exceptions. If you accidentally put your fingers into water or store water in unclean containers day after day, microorganism (微生物) will enter the water.
With the help of surrounding temperature, and sunlight streaming through windows, these microorganisms multiply quickly. Sooner or later, the water will be in the charge of the unfriendly bacteria. And if you drink the water too often, then you’re more likely to be ill.
And what about water in plastic bottles? Heat and plastic are a bad combination, US researcher Kellogg Schwab stresses. When plastic bottles are used at high temperatures, they produce a chemical called BPA. BPA is something that affects hormones (荷尔蒙) and research has tentatively linked it to “several health damage, including heart disease and cancer”, Time reported.
Schwab suggests replacing disposable (一次性的) plastic bottles with the refillable containers made of metal or glass to deal with BPA.
1.The purpose of the first paragraph is to ________________.
A. show an example B. draw a conclusion
C. analyze a phenomenon D. introduce a topic
2.Which of the following may Truls Krogh agree?
A. If the water tastes different, we shouldn’t drink it.
B. The water held in a clean container is likely safe to drink.
C. Although kept fresh, water may still have much organic matter.
D. Covered water can last for a thousand years.
3.What can we infer from the passage?
A. BPA does little harm to our health.
B. Tap water is always safe to drink.
C. Microorganisms are easy to produce in the heat.
D. Disposable plastic bottles have been banned already.
4.What can be the best title of the passage?
A. Why Water is Tasteless B. How to Get Clean Water
C. Does Water Really Go Bad? D. Learn to Protect Water

Nobody needs reminding that exercise is good for our health, but we may need reminding that it needs to be done in the right way.
Light exercises are a great way to improve circulation and keep our muscles active, especially if the rest of the day will be spent sitting in front of a computer or in a lecture hall. However, certain sports like long distance running require training to build up our bodies so they can handle the challenge. If we go into such sport cold, it can shock our muscles, hearts, lungs, and other organs and cause severe pain or in some cases, even death.
Some people are born with medical conditions that go unnoticed until they stress the unstable part of their body. A weak heart may never be seen until we do something that causes extreme physical effort. Recently there have been cases of people dying while running long distances. Also, a university student died after taking a 1.000m running exam. Some universities and high schools have cut long distance races (i.e. 3.000m, 5,000m) from their campus sports games, partly because of the supposed danger and partly because they say fewer people are entering such events.
Maybe education about such events is lacking, especially during primary and high school. People participating in such competitions should realize that a reasonable amount of training is required beforehand and having a medical check is wise, especially for a marathon. People shouldn’t be forced to participate in events that push them past their limits, especially if they haven’t warmed-up completely. Cancelling events could lead to people becoming less healthy and overweight. Maybe these events shouldn’t be cancelled, but organizers and participants should be more careful about regular health checks.
1.Why does the author write the text?
A.To give us some reminding on exercises.
B.To persuade us to take less sports.
C.To advise students to have regular exercises.
D.To require cancelling long distance running.
2.What does the underlined word “cold” in paragraph 2 probably mean?
A.Having trained a lot. B.Without any preparation.
C.Having a low temperature. D.In an unfriendly way.
3.Why do some universities and schools cancel long distance races?
A.Because no students are willing to enter such events.
B.Because the students’ physical conditions are too poor to finish them.
C.Because long distance running is not fit for students.
D.Because they worry about the supposed danger in such races.
4.What does the author advise us to do before running a marathon?
A.Have a medical check and warm-up exercises.
B.Push ourselves past our limits.
C.Participate in it confidently.
D.Try to lose some weight first.
