There are some injuries that are common to all types of extreme sports. The following are some of the important things to do to prevent extreme sports injuries. 1. But they can definitely minimize the risk of injuries.

Warm up.

2. They include a combination of cardiovascular(心脏血管的)exercises, strength drills and stretching. Cardiovascular exercises increase body temperature, heart rate and blood circulation, which is required for further movement of the body. Strength drills increase the stamina of the body, while stretching warms up the muscles preparing them for sudden forceful movements. 3. It also plays an important role in boosting the team spirit for a team sport. A warm-up session should last for at least 20 minutes and it can extend up to half an hour.

Avoid overworking.

There are some people who do not exercise their body for the sport on a regular basis and perform a week's task in a day or two. 4. They do not realize the effect of overworking during the performance and keep doing it until they feel extremely tired. Apart from the actual sport, one should also avoid overdoing the warm-up exercises before the activity.

5.

Just as warming up is essential before any rigorous(充满活力的) physical activity, cooling down the body after playing a rigorous sport is also a significant part of physical conditioning. When you are done with your sports session, you can conclude with some walking, jogging or light running. Slight stretching exercises, focusing on specific muscles, will also be useful for cooling down the body.

A. Cool yourself down.

B. Look for a coach to train you.

C. These people are likely to suffer from extreme sport injuries.

D. However, there are no perfect methods which can assure you 100% safety.

Dolphin or not a dolphin?That is the question!You see,there are several types of dolphins.Some are saltwater dolphins while others are river dolphins.

＂What are the 32 types of dolphins?"When people are asking the question,they are actually referring to the saltwater dolphins in oceans and seas.The river dolphins living in fresh water,are not included in these species.But what would be the answer in this case if we ask,"Dolphin or not a dolphin?"The answer would obviously be yes.River dolphins still belong to the dolphin family.

Among the 32 types of dolphins,some do not actually wear the word"dolphin”in their names,such as the tucuxi,while others actually have the word"whale"as part of their names even if they are not whales but in fact,belong to the dolphin family,for example, the melon-headed whale and the killer whale.So what would be the answer to the question＂dolphin or not a dolphin?"in these cases?It would be yes.All these species do belong to the dolphin family.

Another question that people ask is,"Are the sea animals that perform at aquariums all dolphins?"So,it always seems to come back to the question,"Dolphin or not a dolphin?"

Well the answer is no in this case.The sea animals that perform there are not all dolphins. The beluga which people tend to think belong to the dolphin family because they show what seems like a smile,like most dolphins,are in fact a species of the whale family.

Now that you read these facts about dolphins,you probably realize that certain sea animals may appear to be part of the dolphin species and that others seem to be part of the whale family,but in either case,it is not obvious and can be surprising when you identify a sea animal as being a dolphin or not a dolphin.That is the question!

1.What do we know about the majority of the dolphins?

A.They look like whales. B.They appear friendly.

C.They perform for audience. D.They live in fresh water.

2.What could be added about dolphins before the last paragraph if you were the author?

A.The living area. B.Dolphin training.

C.The eating habits. D.Further identification.

3.This article can be classified as_____.

A.popular science B.literary fiction

C.a travel diary D.a news report

There is no doubt that teens today are extremely busy. Homework piles up and extra-curricular (课外的) activities are time-consuming. Often, teens have to take part in a sport or activity after school, and they are up until 10:00 or later doing homework. Getting teenagers involved in volunteer opportunities can give them a sense of accomplishment that is not connected with sports or school.

Teenagers are often in their own little world. Helping them get involved in volunteering opportunities is the perfect way for them to open up that world and give their time to a good cause.

The key to getting teens involved in volunteer work is to find an opportunity that will fit into their schedule and find something that interests them. Also, keep it close to home. If they have to travel a long distance to volunteer, it’s less likely to be accomplished.

My son has helped with the local library’s reading program for two summers. It is close to home and the schedule is very elastic. We go in and choose days that work with his schedule and he volunteers for about 2 hours at a time. He is responsible for helping kids get signed up for the summer reading program and helping them record the hours they read. It is only a one-week time commitment, but it is very rewarding.

When teens volunteer they often see that there are others more needy than themselves. They also learn time management. Your teen will become a more rounded, less self-centred individual.

Colleges see thousands of students applying for admission every year. If your teen has shown the devotion to volunteer in the community, it can give him the advantage for college admission or scholarship opportunities. So, volunteering is good for their present and their future!

1.What is the text mainly about?

A. The heavy loads faced by teens toady.

B. The benefits of volunteering for teens.

C. The author’s son’s volunteering experience.

D. The requirements of volunteering.

2.The author of the text probably_______.

A. never thought his son would volunteer

B. tries to limit his son’s volunteering time

C. supports his son in volunteering

D. is concerned about his son’s learning

3.We can infer from the last paragraph that_______.

A. colleges show more preference for students with volunteering experiences

B. volunteering can help a teen stand out as an excellent student

C. scholarship opportunities are only offered to excellent students

D. one can’t become an excellent student without volunteering experience

4.The underlined word “elastic” in the fourth paragraph can be best replaced by “　　　　　　 ”.

A. independent　　　　　 B. tight

C. precious　　　　　　　 D. flexible

It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad!

The male giant water bug doesn’t seem to mind a heavy load on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch. The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back.

Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young — as many as 100 — until they can live on their own.

A similar example can be found in emperor penguins living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39° C. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born!

1. What do we know about the giant water bug?

A. It is unable to fly.

B. The eggs grow on the father's back.

C. The male must keep still to hatch the eggs.　

D. The female looks after her eggs together with the male.

2. During the hatching period, the male emperor penguin _______________.

A. is unable to eat

B. is fed by the female

C. tries to lose some weight

D. can't stand the cold weather

3.What is the best title for the text?

A. Mr. Moms in the Wild

B. Animals Do Have Feelings

C. Nature Loves Us like Our Dad　

D. Childbirth in the Animal Kingdom
