【題目】Parents must focus on a healthy balanced lifestyle for their children instead of focusing on weight or dieting in order to prevent obesity(肥胖)and eating disorder among teenagers, say new guidelines from the American Academy of Pediatrics. The guidelines were developed in response to growing concern about teenagers’ use of unhealthy methods to lose weight.

Quick weight loss methods can cause medical consequences such as unstable heart rate. Also, teenagers who diet in ninth grade are three times more likely than their peers(同齡人)to be over-weight in 12th grade, the researchers said. “Scientific evidence increasingly shows that for teenagers, dieting is bad news,” said lead author Neville Golden, Professor at the Stanford University.

Parents should not encourage dieting, and should avoid “weight talk” such as commenting on their own weight or their children’s weight. Instead parents should help their children develop a healthy body image by encouraging them to eat a balanced diet and exercise for fitness, not weight loss, the researchers states. Further, they should also never tease teenagers about their weight. Negative comments about weight can also be detrimental to a teenager’s health.

“Mothers who talk about their own bodies and weights can encourage their kids to have body dissatisfaction, which we see in half of teenage girls and a quarter of boys,” Golden noted. Such dissatisfaction is associated with lower levels of physical activities and with use of laxatives(瀉藥)to control weight.

Families should eat regular meals together, the researchers suggested, adding that eating family meals is likely to prevent weight problems, said the paper published online in the journal Pediatrics. Eating too fast, eating when not hungry, always eating dessert, eating out often are not advisable when you watch your weight.

【1】What is likely to happened to teenagers if they go on a diet in ninth grade?

A. Their studies will suffer a lot

B. They’ll probably have unstable heart rate

C. They’re more likely to be overweight in 12th grade

D. They’ll probably have eating disorder problems

【2】What should parents do to prevent teenager obesity?

A. Urge teenagers to go on a strict diet

B. Comment on their own weight when eating

C. Express their dissatisfaction about their bodies

D. Encourage teenagers to eat healthily and exercise properly

【3】What does the underlined word “detrimental” in the third paragraph probably mean?

A. Strange B. Harmful

C. Necessary D. Deadly

【4】Which is considered helpful to prevent overweight?

A. Eating family meals more often

B. Eating only when hungry

C. Dinning out often

D. Eating too slow

【題目】As we all know ,New Zealandis one of the world's main island groups, extending1,700 kmacross theSouth Pacific Ocean, midway between the Equator and the South Pole.
The NorthIslandand the South Island make up most of New Zealand's 268,000 sq km, an area similar to that of the United Kingdom. Its has a coastline 10，000 kmlong and no inland locality is more than 110 kmfrom the sea.
　 New Zealand is full of every kind of physiognomy (地形，地貌), but is especially for the fact that about three-quarters of the country lies more than 200 meters above sea level. Much of the North Island's shape has been created by volcanic activity. The country lies across the "mobile" belt of the earth's crust which circles the Pacific Ocean. This represents the shape of the land by features all common to the New Zealand landscape — volcanoes, hot springs, mountain chains and active fault lines.
　 The centre of theNorthIsland is crowned by mildly active volcanoes reaching a height of2,797m onMountRuapehu. New Zealand's famous thermal (溫泉的) region runs northeast from here, through the country's largest lake, Taupo, and Rotorua to White Island in the Bay of Plenty. It is the centre point of the500 km longSouthern Alps, a wild region of spectacular alpine peaks, lakes and remote "sounds". Beyond the mountain areas lie extensive rolling downlands in regions such as South Canterbury in the south andHawkesBay in the north.

【題目】There is always something that happens in the world that everyone fears will happen to their town, city or country: natural disasters. The scariest part of it is that no one will ever see it coming. Though technology helps us prepare, but it never actually tells the people when it's going to hit. It is always estimated but the result is never 100% accurate.

However, that is not the point of this article. Two different natural disasters in two different parts of the world have happened in the past few weeks. One was a major flood that has hit Louisiana in the United States. The other was an earthquake that hit Amatrice, Italy. However, there is a major difference in the news coverage of the two tragedies.

As for the flooding in Louisiana, it is reported that this disaster is the worst to hit the United States since Super-storm Sandy and it'll cost at least $30 million. In only the first couple of weeks, 13 people had died. However, like me, many people did not hear about this tragic event. I did not learn about it until about three weeks after it happened.

In Italy, however, it covered all media instantly. The earthquake in Italy happened on Tuesday morning. That same day, I was on Twitter and that was all that was over the news feed. Every other post was about the earthquake. Some would have the opinion that Amatrice, Italy was one of the most beautiful towns in that country. I got in deep sorrow because there were more people killed in this quake than the flooding. So far, they have a total of 73 dead and over one hundred missing.

I understand that technically the earthquake in Italy was worse than the floods in Louisiana. However, I believe that if a natural disaster happens, they all should be equally covered and taken equally seriously. We are one world united and should be there for all of the people who are in need of help. We may not be able to accurately predict disasters but, we can surely lend a hand out for the needy.

【1】What really concerns the author about the two natural disasters?

A. The death and the injured. B. The media report.

C. The government's responsibility. D. Their economic loss.

【2】Why did the author learn about the flood so late?

A. He didn’t care about the flood.

B. He felt nervous about the news.

C. The media didn’t cover it in time.

D. The flood frightened the author a lot.

【3】What can be inferred from the passage?

A. Italy isn't good at predicting the natural disasters.

B. All natural disasters should be covered equally.

C. The world should be united into one instantly.

D. America should help Italy predict natural disasters.

【4】How is the text mainly developed?

A. By making a comparison. B. By following the time order.

C. By listing some examples. D. By analyzing the causes.

【題目】根據(jù)短文內(nèi)容, 從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。選項(xiàng)中有兩項(xiàng)為多余選項(xiàng)。
April 22nd every year marks the start of Earth Day, a day that is celebrated annually to raise awareness about our home planet and how we can save it from being damaged.
①Green-up your home
This is one of the most common things that people do whenever Earth Day rolls around, that is, switch off(關(guān)閉) their lights. Conserve(節(jié)約) energy by switching off all power or electricity points whenever they are not in use. In addition, take out all the plugs from plug points even after switching them off.
②
Cars, being the greatest source of air pollution, can be left at home this weekend. Other greener choices are carpooling, riding a bike or you can also walk if you want a healthier choice and if your workplace is not that far away from your home.
③Be a little dirty
No, we don't mean it 'that way'. We simply mean to say, don't take a bath. Yes, conservation of water is super essential. A day or two without a bath won't harm you, but it will certainly do a lot of good for our planet. A daily shower isn't a matter of health; it's a matter of comfort.
The future of our planet is in your hands!
A. Started in the year 1970, Earth Day is now celebrated in more than 190 countries each year.
B. Showering every day can wash away the natural oils that our skin and hair need.
C. Do something every day that will improve your surroundings to make the planet a better place to live in.
D. Traveling via public transport is the better choice.
E. Leave your cars at home.
F. Below, we have made a list of things you can do to celebrate Earth Day.
G. However, this is not something you should do just for a day or for only an hour.
