Reading: Read the following passage and choose the best answer. Zhong Nanshan is a famous Chinese doctor. He is kind and hard-working, he plays an important role in curing infectious disease(治疗传染病). Zhong always told the truth. In 2003, a terrifying (可怕的) disease, SARS (非典型性肺炎) , caused(导致) many people to be sick and even to die in China. When some experts(专家) said chlamydia (衣原体) was the main cause(原因) of SARS, Zhong had a different opinion. He thought chlamydia might be one cause of death, but not the only cause of SARS. Not long after that, he created an effective treatment method (有效的治疗方法) for SARS. Thanks to it, many patients(病人) became well. Zhong, now 82, still sees patients at his hospital, as well as teaches young doctors. These days, 2019-nCoV(新型冠状病毒) becomes worse and worse, and it makes many Chinese become ill. At first, some experts thought the virus(病毒) couldn't spread from human to human. But Zhong searched(研究) carefully, and found the truth is different. This has helped the government and doctors contain the outbreak(遏制疫情爆发). Zhong Nanshan is a good doctor, we can learn a lot from him, to be hard-working and always tell the truth.
