Kyle Cassidy and three other members of the Annenberg Running Group were stretching on the grounds of the University of Pennsylvania, waiting for a few latecomers. The Penn colleagues and other community members meet three days a week for a roughly 30-minute jog and an occasional lecture. That's right― during some runs, one of them delivers a talk. Topics range from the brain to Bitcoin.
But on this day last January, it would not be their normal run. The first clue that something was off was the man who sprinted past them. "Running at an amazing pace," Cassidy told Runner's World admiringly. Cassidy discovered why the sprinter was so fleet of foot when another man ran by, yelling, “Help! He took my phone and laptop!"
At that, the group did what running clubs do: They ran, trailing the suspect down the streets of Philadelphia until he ducked into a construction site. The runners split up. Cassidy ran around to the far side of the site to cut the thief off while the others wandered the neighborhood hoping he had dumped the loot

No luck. So they decided to ask residents whether they'd seen the guy. When they knocked on the door of one row house, they were in for a surprise. Unknown to them, he had already emerged from the construction site—and was hiding behind a bush by that very house. As the owner opened the door, the suspect darted out from behind the bush ... and right into the arms of campus police, who'd joined the chase shortly behind the runners.
The members of this running group are not hard-core athletes. But they do understand the benefit of a little exercise. “Running is typically a useless sport where you turn fat cells into heat,” Cassidy told The Philadelphia Inquirer. “But occasionally it can be useful, and here was one of those opportunities.”
4．Why do the group members gather together?
A．To do some stretching. B．To have a regular run.
C．To deliver a lecture. D．To cover some topics.
5．What does the underlined word “sprinted” in Paragraph 2 probably mean?

An infectious disease is a disease that is caused by the invasion of a host by pathogens（病原体）whose activities harm the host’s tissues and can be spread to other individuals.
Microorganisms（微生物）capable of causing disease are called pathogens. A true pathogen is an infectious agent that causes disease in any possible host. The terms “infection” and “disease” are quite different. In order to cause disease, pathogens must be able to enter the host body, stick to specific host cells, invade and multiply and do damage to host tissues.
Pathogens may be spread through either direct or indirect contact. Direct contact occurs when an individual is infected by contact with the infection source. It also includes taking in the infectious droplets released by sneezing or coughing. Indirect contact occurs when a pathogen can survive the environment outside its host for a long period of time. So lifeless objects that are polluted by direct contact with the infection source may be the indirect contact for easily infected group.
Public health measures typically involve killing the pathogen from its source or from its route of spread. Those measures include ensuring a safe water supply, effectively treating waste water, and initiating animal control and vaccination（疫苗）programs, etc. Personally, the first line of defense is to keep pathogen at bay by following good personal hygiene（卫生）habits. Prevent infection before it begins and avoid spreading it to others with some easy measures, such as washing hands, getting vaccinated and so on.
Man never stops fighting against all kinds of infectious diseases. But in the past two decades at least a dozen “new” disease have been identified, and traditional diseases that appeared to be “on their way out” are re-emerging. Globally, infectious diseases remain the leading cause of death. Clearly, the ballet has not been won. Nevertheless, it is increasingly difficult for most of us to deny the claims of science. We are continually presented with great amounts of relevant scientific and medical knowledge, which encourages us to take more responsibility for our own health.
8．What’s the main idea of paragraph2?
A. Origin of true pathogens.
B. Strategies for avoiding tissue damage.
C. Nature of infectious diseases.
D. Differences between infection and disease.
9．What is likely to cause disease spread through indirect contact?
A．Breathing in tiny drops from coughing
B．Embracing an infected person.
C．Getting bitten by an infected cat.
D．Using umbrella a sick man used.
10．What does the underlined phrase “at bay” in paragragh 4 mean?
A．At risk. C．Under control.

B．Stay away. D．Within reach.
11．What can we infer about the last paragraph?
A．Science plays an important in defeating infectious diseases.
B．Man is at a loss about infectious diseases.
C．Traditional infectious diseases are dying out.
D．The battle against infectious diseases is in vain.

If you think you’d like to live on Mars, you may have that possibility by 2023. A Dutch company called Mars One will soon advertise for people interested in colonizing (开拓) Mars. If you have all the necessary skills, you could be one of the first colonists. Are you ready for the challenge?
You won’t have to pay for the mission to Mars. Mars One has already received money from some donors and is hoping to get more from TV viewers who will become interested in the show where all applicants have a debate for the rare chances.
The main responsibility of the first colonists is to create an artificial environment on Mars where there is no air to breathe and no land to farm. Scientists know it’s quite possible because something similar has already been done in Antarctica.
Another problem is that space travel to Mars takes nearly a year to get to Mars and the colonists will live the rest of their lives there. When a human lives in an environment without gravity or with low gravity for a long time, the systems in the body weaken. Luckily, spinning (旋转) the spaceship can create artificial gravity, and artificial gravity can ease these problems. It will also be difficult for Mars colonists to be far from home, living in small spaces, and seeing the same people over and over. Colonists with depression could put the mission in danger. Fortunately, a few years ago, a joint Russian and European project called the Mars500 Mission studied people’s reactions in a Mars-like environment. It is viewed as a great success because scientists were able to see how people handle emotional and physical stresses.
Recent studies show that seven percent of people would want to go on such an adventure.
Mars One will soon start accepting its first colonists. Are you interested?
12．What do we know about the applicants to Mars from the first two paragraphs?
A．They will land on Mars in 2023.
B．They can get money from donors.
C．They will compete in a TV show.
D．They do not need special skills.
13．What will the first colonists do to solve the basic living problems on Mars?
A．Create earth-like conditions.
B．Build labs in Antarctica.
C．Spin the spaceship.
D．Start the Mars500 Mission.
14．What can the life of the first colonists be like according to the passage?
A．Difficult and dangerous.
B．Different but adaptable.
C．Challenging and unbearable .
D．Acceptable but depressing.
15．What’s the best title for the text?
A．Mars: our final destination?
B．Ready to be Mars’ colonists?
C．Space travel: a thrilling adventure?
D．Are you a qualified Mars astronaut?

She now spends her days creating meals and sharing ideas with people from around the world. When asked if it was exhausting to smile for the cameras every day, Ray said, “No, it’s fun. 18 .”
