In 2030, 42 percent of American adults will be obese, and about one-quarter of that group will be severely obese, a condition that shortens life and wastes large medical expenses, a new study predicts.
Obesity related ailments — diabetes, heart disease, kidney failure — consume at least 9 percent of health-care spending the United States. Some researchers believe the cost may be twice that estimate. Total health spending is about $2.6 trillion a year.
In 2030, 42 percent of people are projected to be obese, and 11 percent severely obese. Obesity is a body mass index , which suggests 85 kg for someone 1.67 meters tall. Severe obesity is 112 kg for someone that height.
Obesity is rising in higher-income men. Severe obesity is increasing in both sexes. It was 6.2 percent in women in 1999 and 8.1 percent in 2010. For men, it was 3.1 percent in 1999 and 4.4 percent in 2010.
It is believed that the obesity rate is closely related to the following factors: the price of gasoline, which discourages walking when it is low; access to the Internet (and other technologies), which encourages long periods of sitting still; and restaurants per 10,000 people, which increases eating out and weight gain when the number goes up.
Urgent measures must be taken to inspire people to exercise more and educate people about better eating habits before too many people will be suffering from being . obese.

Do you want to live forever? By the year 2050, you might actually get your wish — if you are willing to leave your biological body and live in silicon circuits （半导体电路）．But long before then, perhaps as early as 2020, some measures will begin offering a semblance of immortality （虚拟的永生）.
Researchers are confident that technology will soon be able to track every waking moment of your life. Whatever you see and hear, all that you say and write, can be recorded, analyzed and added to your personal chronicles （履历）. By the year 2030, it may be possible to catch your nervous systems through electrical activities, which would also keep your thoughts and emotions.
Researchers at the laboratories of British Telecommunications have given the name of this idea as Soul Catcher. Small electronic equipment will make preparation for Soul Catcher. It would use a wearable supercomputer, perhaps in a wristwatch, with wireless links to micro sensors under your scalp（头皮） and in the nerves that carry all five sensory signals. So wearing a video camera would no longer be required.
At first, the Soul Catcher's companion system — the Soul Reader — might have trouble copying your thoughts in complete details. Even in 2030, we may still be struggling to understand how the brain is working inside, so reading your thoughts and understanding your emotions might not be possible. But these signals could be kept for the day when they can be transferred to silicon circuits to revitalize minds everlasting entities （永生实体）. Researchers can only wonder what it will be like to wake up one day and find yourself alive inside a machine．
For people who choose not to live in silicon, semblance of immortality would not be as useless as they thought. People would know their lives would not be forgotten, but would be kept a record of the human race forever. And future generations would have a much fuller understanding of the past. History would not be controlled by just the rich and powerful, Hollywood stars, and a few thinkers in the upper society.
【小题1】The main idea of this passage is that _______．
| A．human beings long for living forever |
| B．there are many difficulties in making the Soul Catcher |
| C．people might live forever as technology develops |
| D．the invention of Soul Catcher has great importance |
| A．a new machine on which research measures have already been made |
| B．a new invention in order to catch and keep human's thoughts and emotions |
| C．made by British scientists to offer something that looks like living forever |
| D．made of silicon circuits which can catch people's nervous activity |
| A．to be a reality sooner or later | B．far from certain |
| C．just an idea that couldn't t be realized at all | D．a fading hope |
| A．make dead | B．make famous | C．make known | D．make active |
The US space agency NASA is looking for people to go to Mars, and stay there. This attractive career is for people who want a huge change of scenery and planet. The project is called the Hundred Years Starship, which aims to colonize (开拓殖民地) other lands such as the red planet Mars.
Settlers would travel to the red planet and live there forever. NASA says it would be too expensive to bring humans back to Earth. The space agency can afford, however, to send supplies to the astronaut pioneers from Earth. Astronauts would be landed on the planet's surface and would never be able to return home due to the cost.
NASA has started the project with $1.6 million, and hopes to attract investment from space-living billionaires. Google co-founder Larry Page told NASA he would be interested if the cost of a one-way ticket can go down from $10 billion to $2 billion.
The journey to Mars could take 4 months. Setting on the red planet would be extremely dangerous, especially given the freezing temperatures there. The thin atmosphere would be another problem as it is mostly carbon dioxide, so oxygen supplies are a must. A director in NASA said that he believed the trip might start with visiting Mars's moons first. He claimed that humans could be on Mars's moons by 2030.
Many scientists think colonizing space is absolutely necessary. Steven Hawking believes we must move to other planets to survive as a species. He said: “Once we spread out into space and establish independent colonies, our future should be safe.” Scientists Dirk' Schulze-Makuch and Paul Davies also call it a “desirable goal”, though there surely are huge risks to explore new lands.
【小题1】Which of the following is TRUE about the Hundred Years Starship?
| A．It has cost NASA around $10 billion. |
| B．It is expected to be conducted on Mars in 2030. |
| C．It aims to explore new lands in the universe. |
| D．It is a project first raise by Steven Hawking. |
| A．used to be an astronaut | B．is no longer rich now |
| C．is a fan of space travel | D．is a generous man |
| A．One-way trip to Mars |
| B．Mars's another moon is found. |
| C．Human landing on Mars. |
| D．NASA's first cooperation with Google. |
