Sally Dawly is a woman from Auburn, California. Over the last three and a half years, the anti-littering woman has spent most of her free time picking up cigarette butts (烟头) from the streets of her home city.

Called the “Butt Lady” by her local community, Dawly began her mission to rid the streets of her city of cigarette butts in October, 2014. The woman looked for cigarette butts, picked them up and threw them in the trash. To keep a count of how many butts she picks up, the Butt Lady has been using a tablet, and earlier this month, she hit a historic milestone—one million cigarette butts.

“I got tired of going on my walks and seeing cigarette butts everywhere,” Sally Dawly said. “I’m just shocked that I had to pick up so many. I’ve ever picked up 3,000 butts in one day,” she said. “Don’t throw away your butts; better yet, stop smoking.”

With so many cigarette butts littering the streets, can one person’s efforts really make a difference? Surprisingly, the answer seems to be yes. Soon after the Butt Lady of Auburn started her mission and word of her efforts spread, cigarette cans started appearing around bars and restaurants in the city. Members of the local community even came out to cheer her on as she approached her one-million-butt milestone.

Sally knows her city’s cigarette butt littering problem won’t be solved anytime soon, but she hopes her work will inspire people to at least think twice before dropping cigarette butts in the streets. She has decided to continue cleaning up after irresponsible smokers, and already has a new milestone in her sights—two million cigarette butts.

Word of the Butt Lady’s efforts to keep the streets cigarette butt-free has reached neighboring communities as well, and CBS Sacramento reports that other cities have started seeking her help as well.

4. Why does Sally Dawly carry an iPad with her while picking up the butts?

A．To entertain the crowds.

B．To monitor the smokers.

C．To attract people’s attention.

D．To record the number of butts.

5. How did Sally Dawly feel when picking up cigarette butts?

C．Frightened but content.	D．Astonished and desperate.

6. From the text. what can be inferred about Sally Dawly?

A．She picks up nearly 3,000 cigarette butts every day.

B．She will work in other cities in California in the future.

C．She has set a new goal of picking up two million cigarette butts.

D．She picked up one million cigarette butts with members of her community.

7. What is the text mainly about?

A．California’s “Butt Lady”.

B．Fighting against smoking.

C．Californians health problems.

We've all experienced it. We invite a friend to dinner, only to learn that she is the dreaded "V-word". Vegan is someone who allows a diet that contains no animal meat, fish, eggs, dairy products, or any other food that comes from animals. They differ from vegetarians, who generally still eat dairy and eggs as part of their diets. Vegans also typically abstain from using any other products that come from animals, such as honey and leather jackets.

Back in 2008, vegans only accounted for around 0.5 percent of the U. S. population, or about one million people. As of polls taken in 2014, vegans now make up roughly 2.5 percent of the population. At least in the United States, women seem to be far bigger fans of veganism, making up around 79 percent of vegans.

People on a vegan diet tend to be leaner. In a cross-sectional study of nearly 40,000 adults, meat eaters had the highest mean body mass index, or BMI. Vegetarians were in the middle, and vegans had the lowest. Based on several studies from Finland, some scientists have suggested that vegan diets may be helpful in the treatment of rheumatoid arthritis(类风湿性关节炎). Vegans also appear to have lower rates of hypertension(高血压) than both meat eaters and vegetarians. Vegans also typically have lower cardio metabolic(心脏代谢) risks for conditions like heart disease or strokes.

While there certainly may be some health advantages in going vegan, there seems to be some common deficiencies in the diet. One of these deficiencies is with the vitamin B-12. The ADA states that there are no natural plant foods that contain any significant amount of the vitamin. Vegans can still get it, but they need to take a vitamin or consume fortified foods like soy milk and certain breakfast cereals. Omega-3 fatty acids(欧米珈-3 脂肪酸) are also very difficult to come by on a vegan diet, but this can be overcome through the consumption of algae(海藻) supplements. With vegans requiring supplementation to meet their nutritional needs, it supports the claim that veganism is unnatural, but that doesn't necessarily mean it's unhealthy.

Many health organizations, including the ADA, state that well-planned vegan diets are healthy and nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases. It seems like no matter what your dietary preferences are, a healthy lifestyle can be achieved on or off a vegan diet.

“Today, technical innovations dominate our everyday life in many areas. New technologies, however, always are associated with risks-and these are also seen by laymen,” says Christoph Böhmert, first author of the recently published study and researcher of the Science Communication Group of KIT's Institute for German Studies. “It is crucial to enable adequate communication between science and society, which does not only consider scientific findings, but also concerns of the population.” The study clearly showed that communication of risks may be complicated sometimes. Information on efficient precautions was found to lead to an increased risk perception by the recipients of the information.

In their study, the researchers analyzed communication about a technology that has become indispensable in our life-mobile communications and the electromagnetic fields(电磁场) on which it is based. All over the world, radiation protection authorities, such as the German Federal Office for Radiation Protection, communicate the current state of research into risks of electromagnetic fields as follows: Investigations made and all findings obtained so far do not allow any conclusions to be drawn with respect to mobile communications being a risk for human health. But, the experts continue, there still are knowledge gaps as regards long-term impacts. Then, measures are recommended to reduce exposure of the individual to electromagnetic fields.

It had been known from previous studies already that information on precautions may increase worries. It had been suspected that people conclude from the recommendation of precautions that there really is a risk. This effect was not confirmed by the recent study. The scientists rather attributed the increased worries to a lack of knowledge about the propagation(传播) of electromagnetic fields.

Within the framework of the study, the recommended precautions were submitted to 1717 Australians, together with one of six information brochures providing scientific background information. When test persons were given not only the recommendations, but also explained why observation of these tips strongly reduces their exposure to electromagnetic fields, worries increased. For example, scientists explained to the test persons that telephone conversations with a headset largely reduce exposure. When a mobile phone is located ten centimeters instead of just one centimeter away from the ear, the electric power absorbed by the ear is about one hundredth of the initial value. Hence, their own mobile phone usually causes an exposure that by far exceeds that of mobile communications stations that are generally referred to as “cellphone towers”. While the scientists wanted to explain the effectiveness of precautions, test persons mainly considered this information to be an indication of their mobile phone-not the transmission towers-being dangerous. As a result, they perceived increased risk potentials for telephone conversations with their mobile phones.

“The study reveals that messages on precautions and information are a double-edged sword in terms of subjective risk perception. Their use should be far better understood,” Boehmert says.

B．Mobile communications definitely do harm to people's health in the long run.

C．Information about technologies and their risks may have undesired side effects.

13. According to the passage, we can conclude that the best way to relieve the inappropriate worries is to _______.

B．produce new electric products with a lower radiation value

C．provide the public with less information on effective precaution
