Learning Procedure
Activity 1
1. Read the passage and underline all the modal verbs in the passage.
It is widely acknowledged that the Chinese government has spared no effort to stop the coronavirus from further spread. The official coronavirus statistics for China include more than 84,600 infections and over 4,600 deaths. The majority of both are in Hubei province, where the virus might have originated in a wet market. Strict lockdown measures and great dedication to the development of rapid test kits must have contributed to ending the outbreak in China, so that life is returning to normal even in Wuhan itself.
However, since the outbreak of the pandemic,U.S. President Trump has kept searching for parties to blame, who firmly believes that China must have initially covered up the outbreak and couldn’t have been truthful about the scope of the epidemic. He has said several times that China could have stopped the coronavirus before it swept the globe. He pointed out that China should have informed the World Health Organization about the new virus earlier.
Despite all these groundless accusations, experts in China have already taken the lead in developing a rapid nucleic test kit for the virus in the city of Wuxi. The newly developed kit can detect the virus within 8 to 15 minutes, according to the city bureau of science and technology. It is believed that its high sensitivity should have saved huge amounts of time previously wasted in identifying the novel type of the virus and its simple operation might have brought great convenience to transport.
The kit was the joint work of experts from the National Institute for Viral Disease Control and Prevention and a Wuxi-based high-tech company. The company received a notice to develop the kit which on Jan. 20, and it is now undergoing mass production. The company has confirmed that it can produce kits for 4,000 people a day, and the city government is helping the company expand production.
