It was a dark and stormy night. I was about to go to bed when I heard a tapping sound on my window.
“Who's there?” I shouted. Suddenly there was a flash of lightning; I saw a face at the window. It looked like an alien(外星人) an alien that I had seen on the television show, “the X files”.
I felt very scared. I ran to my bed and pulled my blanket over my head. I started to shout for my parents but there was no reply. Then I remembered that they were at a fancy dress party.
I looked out of my blanket but it was too dark to see anything. Then I heard footsteps. They were getting louder and louder. I ran to my drawer to take out my camera and started to take pictures in the direction of the window. Soon the footsteps died off.
The grandfather clock struck. It was 12 midnight. I went back to my bed and tried to sleep. But I could not sleep. I felt too frightened. I sat up, and my mind was full of thoughts. Time passed finally, I fell asleep.
I woke up only after eight and decided to find out what it had been. I found some footprints outside my bedroom window. I measured them with a ruler and found them to be exactly the same size as my father's shoes. I then went to town to get the film developed. I didn't realize that I did not use the flash until I saw the black photos.
When I reached home, I told my father the whole incident and he started to laugh. I started laughing too when he told me that he had dressed up as an alien for the party. Today, I am still amused to think I was so afraid of my own father.

The situation is that familiar deadlines are approaching, time runs out, disorder and confusion fills the day. The feeling is just as familiar a slightly faster heart rate, and shortness of breath. Yes, it is panic time.
It’s too late to kick yourself with “I should have started on this sooner.” or “It was a mistake to accept this tight deadline.” The only thing left to deal with the situation is to panic more efficiently.
① Focus.
Panic happens when you are on an overload too many things to do, too much pressure, too little time. But if you focus on the tasks that you need to take care of, and line them up in a logical list, you can have better control of a highly stressful and wild situation.
② Get rid of distractions.
Time wasters and unnecessary activities are the last things you need during this time. Let everyone know you are on panic mode and should not be disturbed unless it is an emergency.
③ Watch your time.
Don’t be too engaged in one detail so that you reduce your timing for the other important details. Mind the time and deal with each task so that you can finish all of the required activities sufficiently.
Try to solve a panic situation as quickly as you can so that you can rest and get back your energy and strength for the next one.
4. What can a person in a panic mode do to watch his time?
A. He should wear a watch. B. He should focus on one detail.

C
Work started this week on next season’s flu vaccine (疫苗), with experts working out forecasts about which types of the flu virus will be making the rounds. But don’t expect any improvements. Flu experts are already admitting that most vaccines will give at best basic protection, because they’re based on old-fashioned technology. It’s not a new problem, but one that the slow-moving world of drug and vaccine production seems helpless to improve upon.
Every flu vaccine is a cocktail, aimed at either three or four of the most common flu types. Flu vaccines must be recreated every year because flu viruses develop constantly in a process called antigenic drift. In February, global flu experts gather to trade notes on what viruses are circulating in different countries and to come to an agreement on which types the next vaccines should be made to target.
In recent years, flu vaccines have been based on H1N1, H3N2 and either one or two types of influenza B virus. Each of these has a “reference” type, which is used to make seed virus. Producers add the seed types to eggs and incubate (孵) them as the virus grows. Then they purify the virus, and either weaken it or kill it to make a vaccine.
Using eggs is a tricky (=difficult) and unpredictable process. Sometimes the virus doesn’t grow well in eggs, which can mean less vaccine than expected. The result is a flu vaccine that doesn’t offer much protection. “As long as we have eggs we are going to have this problem,” said Scott Hensley, a flu virus expert, “The only solution is not to depend on eggs.”
Flu is a major killer. The 2017-2018 season has been a severe one, hitting the entire U. S. with widespread influenza infection (感染) at once for weeks on end, and killing 97 children so far. Against this threat, even a less satisfying flu vaccine will definitely help. “Even when you have these mismatches it will not prevent infection but likely prevent disease severity,” said Hensley.
8. Next season flu vaccine fails to improve because ______.
A. it has offered the best protection
B. experts can’t forecast the flu types
C. it is based on outdated technology
D. experts are unwilling to respond to changes
9. According to Paragraph 2, flu experts ______ in February.
A. exchange views on the virus types next season
B. get together and make a deal on vaccines
C. sign an agreement on vaccine production
D. decide on how to circulate the viruses
10. The risk of using eggs to make
