24、What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.
Escaping a fire is a serious matter. Knowing what to do during a fire can save yourself. It is important to know the ways you can use and to show them to everyone in the family, such as stairways (楼梯) and fire escapes, but not lifts.
From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving through windows with the least chance of serious injury (伤害).
The second floor window is usually not very high from the ground. An grown person, hanging by the finger-tips (手指尖) will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may have leaked (泄露) into the room.
On a second or third floor, the best windows for escape are those which open onto a roof (屋顶). From the roof a person can drop to the ground more safely. Dropping onto cement (水泥) might end in injury. Trees and grass can help to break a fall.

26、 History that's hard to trace
Since December, there have been tens of thousands of COVID-19 cases both in and out of China, caused by a previous virus we don't know: novel coronavirus.
It's not the first time for viruses to make headlines. Viruses have brought big trouble to humans, with their potential to cause widespread disease and death.
What are they? Viruses are considered to be non-living organisms (有机物) They can infect animals and plants, making them sick. They include genetic materials like DNA and are protected by a coating of protein.
Unlike bacteria (细菌),viruses can't reproduce (繁殖)on their own. Instead, they invaded the cells of living organisms to reproduce, spread and take over. But the basic question is, where did viruses first come from?
Until now, we still have no clear explanation for their origin (起源). “Tracing the origins of viruses is difficult,” Ed Rybicki, a virologist at the university of Cape Town in South Africa, told Scientific American, “because viruses don't leave fossils (化石) and because of the tricks they use to make copies of themselves within the cells they’ve invaded.”
Understanding the origins of viruses means fully understanding the history of their hosts--not only humans, but also bacteria, plants and other animals, which is a complicated task, says Nature.
However, here are three main theories to explain the origin of viruses. First, viruses started as independent organisms, then became parasites(寄生者). Second, viruses evolved(逐渐形成) from pieces of DNA or RNA that “escaped” from larger organisms. The third one is that viruses co-evolved with their host cells, which means they existed alongside these cells.
For the time being, these are only these theories. The technology and poofs we have today cannot be used to test these theories and discover the most reasonable explanation. Continuing studies may provide us with clearer answers. Or future studies may find that the answer is even more mysterious than it now appears.
【1】What can we lean about viruses from the article?
A.The mainly infect animals and plants. B.They are really small living organisms.
C.They are more dangerous than bacteria. D.They can't reproduce unless they find a host cell.
【2】Which of the following might explain the origin of viruses?
A.They evolved along with their host cells.
B.They evolved from the DNA or RNA in animals.
C.They evolved from the fossils of large organisms.
D.They evolved from parasites to independent organisms.
【3】What do we learn from the article?
A.Viruses live longer in human host cells than in animals'.
B.Viruses will become more like bacteria as they evolve.
C.It may take a long time to understand the origin of viruses.
D.The author is confident about future virus research.
27、 I received a private message on Facebook. It began harmlessly enough: Hey, girl. Wanted to invite you to join in my next project—30 minutes of exercise and healthy eating. Promise to help you “LOSE WEIGHT!”
It was all becoming too much. Facebook was running my life, not me.
But what killed Facebook for me was when I posted a photo, and five minutes later my son asked me how many “likes” it got. His question was a wake-up call.
“Likes” are signs of acceptance and approval. I had forgotten that acceptance and approval need to come from within and had unknowingly set him a bad example.
I tried to remember what life was like before Facebook. Surfing the internet was an occasional (偶尔的) activity, and I spent a lot more time reading books and magazines. I checked in with friends through texts, emails and phone calls.
To recreate the simplicity (简单) of those days and set a healthier example for my son, I closed my Facebook account.
I’d been in the habit of checking Facebook many times a day, so I had to come up with some new habits. I carried a novel and a crossword puzzle book around with me. I rediscovered playing the piano. I started taking yoga classes.
I stopped looking at the world through my cellphone. I felt completely present at the moment. The break left me feeling better about myself, my family, my home and my life.
After a few weeks, I returned to Facebook. Now I look at the photos of my friends’ kids growing up and treasure how Facebook allows me to keep in touch with family far and wide. I have a look at it every day, but no longer with the need to post ideas and photos from time to time.
It is not an addiction (瘾) any more.

A.she wanted to set her son a good example

【2】What can we know about the writer?
A.She isn't interested in reading.
B.She doesn't use Facebook now.
C.Playing the piano is new to her.
D.She lived a simple life before Facebook.
【3】The writer has learned a lot from her experience except _________.
A.we should eat healthily and do more exercise
B.we ourselves should control our lives, not Facebook
C.we should use Facebook correctly to make good use of it
D.we shouldn't care too much about what other people think of us
【4】What can be the best title for the passage?
