As is often the case, it is human nature to lead a sedentary（久坐的）lifestyle and most of us are so involved in our busy schedules that we don't even notice our bad habits. Many worry about the right time or "right age" to start working out. 1. Here're some practical tips to help you get fit.
Master your mind. Most people argue that they are too tired or old to start exercising. Doing so is much easier than trying to change the busy lifestyle. Change your mindset and be more confident in improving your health. 2.
Easy does it. Once you have chosen a fitness program, start slowly and increase it in stages. Begin with just a few minutes of gentle exercises and stretches. 3. About 30 minutes should be devoted to your workout. As your body starts to respond and your muscles get used to the exercises, you can gradually increase the length of your workout.
Always warm up. Always remember to warm up your muscles before exercising. Gentle warm-ups will reduce your risk of injury, aches and pains, and increase blood circulation and flexibility.
4. There's no quick access to getting fit. It's a common mistake to do too much too soon. If you don't know how to balance your needs and your expectations, you might seriously injure your muscles or just create stress.
Cool down. When you finish your routine, you need to cool your muscles and let your heart rate slow gradually. 5.
A.Don't overload your body.
B.Never ignore your potentials.
C.Tell your body to be more active and say, "I can do it."
D.However, nobody cares about what you have done for them.
E.Go next to some mild activity such as walking, jogging or cycling.
F.Cooling down will help your body to return to its pre-exercise level.
G.But it's never too late for them to start exercising and all they need is enough determination.

As is often the case, when people are attending to meetings, having meals or waiting for buses, you can always find them addicting to their phones, completely ignoring others.
This is really a common phenomena in our life. The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat. Therefore, too much exposure to phones are bad for people in terms of health. Moreover, people involved in phones fail to communicate well with these around them.
As far as I am concerned, people should wisely make use of their phones to help their work and study. Meanwhile, care much about their family and friends rather than mobile phones.

It is one of the greatest mysteries of nature. In case you haven’t noticed, all living things follow very definite, individual rhythms, all as regular as a clock, but what makes them regular?
Though many scientists maintain that these rhythms are the result of some outside force like gravity or radiation or both, the results of most scientific researches agree with other scientists who believe that each living thing has its own built-in biological “time clock.”
Take the mystery of migration for example. Scientists can’t really explain why many species of birds migrate in the autumn even though the temperature is still summery. The birds just seem to snub the comfortable weather that they are having. When a certain time comes, they travel south by the thousand. In spring time, they migrate northwards when though there probably is snow still covering the ground when they finally arrive. Something said “go”, and they did.
Animals that hibernate are obeying individual time clock, too. When their clock indicates the time to take a winter’s nap, they do, and nothing can stop them. At a certain time in the spring, they wake up and come out regardless of the weather outside.
Plants appear to have yearly rhythms, such as the sprouting(发芽)of seeds, and they also have daily rhythms. Notice sometimes that plants raise their leaves in daylight and lower them at night.
If you live along the California coast, you can easily observe a demonstration of this mysterious clock functioning regularly. There, from February to September, the highest tides occur exactly every fourteen and four-fifths days, and during these high tides, but at no other time, small silvery fish called grunions surf-ride a wave to the beach. There the female deposits her eggs in the sand and the male, fertilize them; then both hitch a wave-ride back to the sea. Exactly fourteen and four-fifths days later, never before or after, the tiny eggs hatch, and the high tide carries the new habits out to sea.
1.According to the passage, the mysterious rhythms result from ________.
A.the influence of gravity on living species
B.the effect of radiation on living species
C.the influence of a mysterious outer force on living species
D.the internal mechanism inside the living species
2.The underlined word “snub” in the third paragraph probably means ________.
A.fight B.ignore
C.symbolize D.criticize
3.Which of the following statements is NOT TRUE?
A.Hibernating animals are obeying an internal time clock.
B.The positioning of the leaves of some plants is due to the daily rhythms.
C.The internal clock functioning is demonstrated in the reproducing habits of grunions.
D.The yearly hibernation is more because of the weather influence than the biological functioning.
4.The passage is mainly about ________.
A.the rhythms of life B.the reasons of mysterious hibermation
C.strange behaviors of species D.the timing for different events in the world of species

When humans and nature go head to head, nature often ends up losing. Rivers get polluted. Trees are knocked down. Natural resources are exhausted. That’s what makes the Galapagos Islands so special—it’s one of he few places on the Earth that nature can truly call its own.
For people used to having wild animals run at the scent of humans, a visit to the Galapagos is a real eye-opening experience. Over 1,600 km west of Ecuador, the islands are home to a unique variety of animals that have absolutely no fear of people. Visitors can play on the beach with sea lions and giant sea turtles, swim with dolphins and whales, and get close enough to the penguins to count the eggs in their nests.
The islands were declared a national park over 40 years ago, and the number of human visitors is tightly limited to avoid damaging he environment or putting stress on the animal. Tourists have to pay a $100 daily visitors fee, and can’t step off the boat unless accompanied(陪同) by an official guide. Once on the islands, you have to stay on the trail(小径), but that seldom presents a problem: the animals are so curious about people that they’ll usually come up to say hello.
“It’s a little like being in a zoo,” said one traveler. “But instead of us looking at the animals, the animals, the animals are looking at us.”
Aside from the wildlife, one of the island’ more unusual features is its post office. You can send postcards for free, but the problem is that there’s no postman to collect them. Instead, travelers pick up mail addressed to people who live near them back home, and then hand-deliver the postcards when their trip is finished.
1.The Galapagos Islands are .
A. terribly polluted B. near Ecuador
C. in the Atlantic Ocean D. independent of Ecuador
2.Which animal is NOT mentioned in the passage?
A. Whales. B. Sea lions.
C. Goats. D. Dolphins.
3.On the Galapagos Islands the mail is delivered by .
A. the government B. the post office
C. the tourists D. the guides
4.What would be the bet title for the passage?
A. Special “Zoo” B. Humans and Nature
C. Go Head to Head D. Ecuador—An Island Country
5.What is one of the islands’ more unusual features?
A. There’re some postmen to collect letters.
B. There are only the wild life.
C. You can send letters.
D. Travellers deliver the letters by themselves.
