Perhaps everyone has heard warnings about the “freshman 15”, but is it true that many college students weigh 15 pounds more during their first year at school?

Recent studies find that some first-year students are indeed likely to gain weight, but it might not be the full freshman 15, and it may not all happen during the freshman year. That might sound like good news, but it’s not. Doctors are concerned that students who gradually put on pounds could have healthy problems.

Studies show that students on average gain 3-10 pounds during their first 2 years of college. Most of this weight gain occurs during the first year. A college offers many temptations (诱惑). You’re on your own and free to eat what you want. In addition, you may not get as much exercise as you did in high school. A college is also a time of change, and people sometimes eat in response to (对……做出反应) homesickness, sadness, or stress, and all of these can be part of starting a new life in college.

Some weight gain is normal as a young body grows, but rapid weight gain may become a problem. Weight gain that pushes you above the body’s normal range carries health risks. People who are overweight are more likely to have high blood pressure, heart disease and develop certain cancers.

The best way to beat “freshman 15” is to prevent it altogether. Good habits like a balanced diet, regular exercise, and getting enough sleep can do more than keeping the pounds off. They can also help you stay healthy.

1. The “freshman 15” refers to the fact that the first-year college students ________.

A. are likely to gain much weight    B. can’t get used to living in college

2. According to the writer, the causes of “freshman 15” don’t include ________.

A. getting less exercise          B. being free to eat food

C. feeling homesick            D. having more subjects.

3. What is the best way to beat “freshman 15”?

A. To ask doctors for advice.        B. To pay attention to your lessons.

C. To stop it from happening.        D. To do a lot exercise every day.

4. What can we learn from the text?

A. Getting less sleep can help people lose weight gradually.

B. Overweight people usually have more health risks.

C. Weight gain is becoming serious among college students.

D. Students gain more weight in the second year than in the first.

The world's oceans have warmed 50 percent faster over the last 40 years than previously thought due to climate change, Australian and US climate researchers reported on Wednesday. Higher ocean temperatures expand the volume of water, contributing to a rise in sea levels that is submerging small island nations and threatening to great damage in low-lying, densely-populated delta regions around the globe.

The study, published in the British journal Nature, adds to a growing scientific chorus of warnings about the pace and consequences of rising oceans. It also serves as a corrective to a massive report issued last year by the Nobel-winning UN Intergovernmental Panel on Climate Change（IPCC）, according to the authors.

Rising sea levels are driven by two things: the thermal（热）expansion of sea water, and additional water from melting sources of ice. Both processes are caused by global warming. The ice sheet that sits at the top of Greenland, for example, contains enough water to raise world ocean levels by seven metres（23 feet）, which would bury sea-level cities from Dhaka to Shanghai.

Trying to figure out how much each of these factors contributes to rising sea levels is critically important to understanding climate change, and forecasting future temperature rises, scientists say. But up to now, there has been a confusing gap between the projections of computer-based climate models, and the observations of scientists gathering data from the oceans.

The new study, led by Catia Domingues of the Centre for Australian Weather and Climate Research, is the first to reconcile（与…一致）the models with observed data. Using new techniques to assess ocean temperatures to a depth of 700 metres（2,300 feet）from 1961 to 2003, it shows that thermal warming contributed to a 0.53 millimetre-per-year rise in sea levels rather than the 0.32 mm rise reported by the IPCC.

64. What happens when the ocean's temperature rises?

A. It causes sea levels to rise.

B. It causes sea levels to remain constant.

C. It causes sea levels to decrease.

D. It causes sea level to change.

65. Which of the followings would be buried by the rising sea?

A. Small island nations.

B. All coastal cities around the world.

C. People who enjoy holiday on the beach.

D. Low-lying regions.

66. The new study in this passage _____________.

A. shows that thermal warming contributed to a 0.32 millimeter-per-year rise in sea levels.

B. did not reveal anything that scientists hadn't already known.

C. used new techniques to assess ocean temperatures.

D. shows that models contradict the observed data.

67. What was the main finding of the study?

A. Nothing enough is being done about global warming.

B. That ocean waters have warmed faster than scientists had previously thought.

C. That the warming of the world's oceans is not a threat.

D. A massive report issued last year by IPCC was wrong.
