1211．I had been in the city for some time and was coming home.I missed my boat and decided to travel on an old ship.I knew that it would not be a comfortable journey but I had no time to wait for another boat.
Hardly had we left the port when I saw the dog Gulliver，the captain's favourite dog，for the first time.What a big dog it was！I had never seen one that could frighten me so much!
On the third day the ship caught fire.Nobody tried to put it out.The ship began sinking and all the men rushed to the lifeboats.I saw no chance of getting away in a boat.Suddenly I remembered there was a life raft（橡皮救生筏） on the ship.I had no time，so I immediately rushed towards the raft and pushed it into the water.
In jumping down onto the raft I hurt myself badly and was unconscious for some time.When I came to，I found there was no sign of a lifeboat.Every man who had been on board the ship must have gone down with her.I was the only one who was saved.
Then I saw Gulliver was coming fast towards the raft.It struggled a long time before it managed to get onto the raft.I wanted to push it back into the water but did not dare to move.The dog shook itself，went to the other end of the raft and lay down.I did not dare to sleep that night.I must watch it.In the moonlight I could see its eyes were open.It was watching，too.

.Here are some of the challenges.
Multiplying infections
According to the existing data，the infection rate for SARS is 3 while the ordinary flu's infection rate is about 1.1.Now，based on the first 425 confirmed COVID-19 cases，each infection led to 2.2 more infections on average.（2）.Yet we don't know whether the new virus is weakening or is still learning what it can do.
Varying incubation periods （潛伏期）
Scientists estimated（估計(jì)）the average incubation period was roughly five days，but said it could last up to two weeks.（3）.People can move away from where they got it and not even remember places where they may have been exposed.
Spreading in stealth
Another big worry is that one person with no symptoms can also infect others.On Thursday，scientists reported that a woman who was not ill at the time spread the virus to a man in Germany during a business trip there.（4）.
Testing gaps
（5）.At present，a few types of test kits（工具包）have been developed.But they are not accurate enough.Scientists are not sure how many false alarms or missed cases each might give at any point in time.That leaves a key gap.
Although scientists are still faced with so many challenges，they are confident that the new virus will be put under control soon.
A.More testing equipment should be provided at once.
B.It's still a struggle to determine who is or is not infected.
C.Such a long potential incubation period can be a problem.
D.The rate is a bit lower than SARS but much higher than ordinary flu.
E.That is a very low infection rate compared with that of SARS and Ebola.
F.Then he infected several other coworkers before showing any symptoms.
G.However，new details show how challenging it could be to control this outbreak.發(fā)布：2024/11/1 5:0:2組卷：13引用：1難度：0.51214．The producer comes regularly to collect the cameras
