(a) It became a pandemic.
(b) The source of SARS virus was found in fish in China.
(c) It spread in 2013.
(d) It is a type of a coronavirus.

3. Circle the correct answers in the parentheses and fill in the blanks.

There are many known

coronaviruses, but only

( 5 / 6 / 7 / 8 / 9 / 10 )

of them infect humans,

and can cause disease.

( 1 / 2 / 3 / 4 / 5 / 6 ) of

them cause cold,

mild, highly contagious

infections of the                          

and                          .

( 1 / 2 / 3 / 4 / 5 / 6) of them

infect the                      , and

cause much more severe illnesses.

The

(5th / 6th / 7th / 8th / 9th / 10th),

which causes COVID-19, has 

features of each: it spreads easily,

but can severely impact

the                               .

 

 

  1. Fill in the blanks.

 <Traits of Coronaviruses>

(a) People will be infected when the virus enters their

(1)                             or

(2)                            .

 

(b) Coronaviruses transmit well in

(3)                                      spaces. 

 

(c) Coronaviruses get damaged

when they are exposed to

(4)                                   .

 

(d) Because many of us are not immune to COVID-19,

it may not need

(5)                                       

conditions to spread.    

 

(e) Coronaviruses store their

genes on (6)                           .

 

(f) Coronaviruses have some differences

from other RNA viruses.

I. They are (7)                             ,

meaning they have many genes.

II. They have more chances to make

harmful (8)                               .

III. They are much more

(9)                                    

because their enzymes check

whether there are any errors

in their replication.

 

5. Which of the following statements is not true?

(a) Once we are infected by a virus, our immune system will recognize it and protect us from getting sick again,
(b) Because coronaviruses mutate slowly, it is difficult to make drugs and vaccines.
(c) New antiviral drugs and vaccines are needed every year because viruses mutate slowly.
(d) We have not developed an approved treatment or vaccine for a coronavirus.

 

 

6. Some scientists believe a new coronavirus will always appear occasionally

(a) if we continue taking over other animals’ habitats.
(b) unless we stop consuming fish and meat.
(c) because many epidemics end before their treatments are developed.
(d) because COVID-19 is relatively strong comparing to other corona viruses.
