didn’t touch his eyes, mouth or nose. Then, right after class, he washed his hands.
Tuesday, January 19th
This morning I jumped into the nose of Sam’s best friend, Bill. Unluckily, the mucus (黏液) in his nose
caught me. I thought it was over for me. Suddenly, Bill sneezed (打喷嚏) while he was talking to Sam. I knew that
would send me right into Sam’s face! However, Sam quickly gave Bill a tissue (纸巾), and Bill sneezed into that
instead! Infecting people is harder than I imagined.
Thursday, January 21st
I’m feeling very unhappy today. Some scientists caught my friend Harry and put him under a microscope
(显微镜). Harry is a flu virus and he’s a dangerous little guy. Besides, Sam ate all his vegetables today. He’s
exercising, and he gets eight hours of sleep every night. His body is too strong for me!
Friday, January 22nd
I tried to infect Sam again today, but he washed his hands five times and never touched his face! He also
gave tissues to every student in his class who was sneezing. It’s impossible to give him a cold! So I have to give
up and I’m moving to another school.

（23-24 八年级下·江西宜春·期末）When we hear the word “sport”, we usually think of football,
basketball, the Olympic Games. and things like that. But isn’t a sport more than that? Different people have
different answers.
Many people think that a sport must be hard for your body. But what about if you only need to think? Look
at chess. There are chess competitions and chess stars. So is chess a sport? And do you need to be strong and fit to
take part in a sport? What about Olympic shooting? You don’t have to be strong to do that.
One thing all sports need is skill. A skill is something special you can do better than others. It is often a
thing you learn, but some people have natural skills. Most people can learn to play football. But to be a really
good football player, you need to be naturally quick and move well.
Then there are hobbies, Hobbies are special activities that we like to spend our time doing when we aren’t
working. So a sport can be a hobby, but not all hobbies are sports. Painting and cooking are hobbies. ________ If
your hobby is looking after your garden, people don’t call it a sport. But if you climb mountains—if you’re a
mountaineer (登山运动员) —many people will say you’re taking part in a sport. Maybe that’s because
mountaineers compete—in other words, they try to do better than other climbers. Finally, what are games?
Football is a game—but chess, video games, and hide and seek are games, too, each with its own rules. Is a game
something we do just for fun? That’s also true for hobbies. And some games are clearly sports, but people don’t
agree about others.
There are different activities, For some, you have to be fit and strong. For others, you have to be smart or
quick, But are they sports, games or hobbies? You decide.
1．What does the underlined word “It” in Paragraph 3 refer to?
A．A rule. B．A skill. C．A garden. D．A competition
2．Why do many people think mountain climbing can be a sport?
A．Because mountain climbers compete.
B．Because mountain climbers have fun.
C．Because mountain climbing is their hobby.
D．Because mountain climbing doesn’t need skills.3．Choose the best sentence to fill in the blank “________” in Paragraph 4.
A．But few people do them after sports. B．And they need some natural skills,
C．But no one calls those things sports. D．And people spend their free time on them.
4．What do we know about games according to the passage?
A．People have to be strong to do them. B．They are less interesting than hobbies.
C．They are things people need to learn D．Most of them have their own rules.
5．What is the topic of the passage?
A．Success. B．Sports. C．Family. D．Olympics.
【答案】1．B 2．A 3．C 4．D 5．B

（23-24八年级下·北京东城·期末）Scientists have studied the full genetic (基因的) information of more
than 18,000 cancer samples. They found new information about the patterns of mutations (突变) , or changes,
which could help doctors provide better treatment.
Their study, which appeared recently in the publication Science, is not the first to do such a complete
genetic study of cancer samples. But no one has ever used such a large sample size.
Serena Nik-Zainal of the University of Cambridge was part of the team that did the research. She said this
was “the largest cohort (群体) in the world. It is extraordinary.”
Over 12,000 samples in the study came from patients recruited (招募) by Britain’s National Health Service.
They were part of a project to study whole genomes (基因组) from people with common cancers and rare
diseases. The rest of the data came from existing cancer data sets.
Researchers were able to study such a large number because of the same improvements in technology that
recently permitted scientists to complete the map of the entire human genome.Andrew Futreal, a genomic expert at MD Anderson Cancer Center in Houston, was not involved in the
study. He said the study gave scientists some knowledge of the destructive (破坏性的) forces that caused cancer.
Cancer is a disease of the genome or full set of instructions for running cells. It happens when changes in a
person’s DNA cause cells to grow and divide uncontrollably. DNA is a substance (物质) that carries the genetic
information in the cells of living things, like a human. In 2020, there were about 19 million new cancer cases
worldwide.
For the study, researchers looked at 19 different kinds of cancer in the human body. It identified 58 new
“mutational signatures”, or pieces of evidence leading to the causes of cancer. Nik-Zainal said researchers also
confirmed 51 of more than 70 previously reported mutation patterns. Some arise (出现) because of problems
within a person’s cells; others are caused by ultraviolet (紫外线的) radiation, tobacco smoke, or chemicals.
Knowing more of them “helps us to understand each person’s cancer more precisely,” which can help guide
treatment, Nik-Zainal said.
Genetic sequencing, the process used to study the makeup of a cell, is already being included in cancer
care. It is part of the growing move toward personalized medicine, or care based on a patient’s genes and specific
disease. Now doctors will have much more information to draw from when they look at individual cancers.
To help doctors use this information, researchers developed a computer program that will let them find
common mutation patterns and seek out rare ones. Nik-Zainal said doctors could suggest a treatment based on a
special pattern.
Futreal said the data can also show doctors what tends to happen over time when a patient develops a
cancer with a certain mutation pattern. This will help doctors give earlier treatment and hopefully stop the
developing disease.
1．Which of the following statement is true?
A．Scientists have studied the full genetic information of more than 18,000 cancer samples.
B．They found new information about the patterns of mutations, or changes, that could help doctors provide
better treatment.
C．Their study, which appeared recently in the publication Science, is not the first to do such a complete
genetic study of cancer samples.
D．All of the above.
2．What can we infer from the passage?
A．Cancer is a kind of disease that happens when DNA in cells grow or divide.
B．Some cancers arise because of problems within a person’s cells.
C．Some cancers are caused by ultraviolet radiation, tobacco smoke, or chemicals.D．Genetic sequencing has been used in medical treatment.
