A couple of weeks ago, my grandfather was explaining his favorite expression. "Nothing is ever easy?The following day, as I tried to complete my day's work, I happened to notice a bumblebee （大黄蜂）on the skylight （天窗）.The skylight was particularly high up, but I thought removing the bee would take no more than five minutes. An hour later, the bee still remained. All that had changed was that the

living room was a mess and that 1 was dizzy from looking up into the sunlight. I

did not expect to waste an hour on an insect so tiny, but by doing so, I understood what my grandfather meant.

It is not only time that we tend to underestimate - we don’t account for unexpected costs. We often imagine what can work in our favor5 but we seldom think of all the negative things that could a fleet us. However, it is important to remember that your day or week or year might nor go as planned, and that is completely normal. It is perfectly acceptable to feel challenged 一 even at a task you thought was simple 一 because that is part of life.

If you can accept that nothing will ever be easy, then lite might seem slightly more manageable. In middle school. I thought high school might be easier because I could choose the classes I wanted to take. In high school I thought college might be easier because I could have a schedule （计划）best suited for myself. Yet each time, I was both wrong and disappointed. After accepting that school wouldn't （and shouldn't） be easy. I found myself with a more positive altitude and improved results.

Of course, there should be preparations made to account tor expenses or time. Doing so can only help you accomplish your goals in a better way. However, there is no need to beat ourselves up when something stands in our path. Maybe we cannot see a bee coming our way, but we can always give ourselves the extra lime to catch it.

4.Why did the author mention his experience of removing a bee?

A.To share something unforgettable with us.

B.To lead us to what the author learned from it.

C.To show the unexpected costs it caused.

D.To tell us how easy it is to waste our rime.

5. Why do things often tum out to be different from what we expect?

A.We often don't take lime seriously.

B.We tend not to have enough money.

C.Unexpected things can happen.

D.It is easy to feel challenged.]

6.According to the text, what does the underlined phrase ^beat ourselves up" mean?

A.lo hit or kick ourselves hard, many times

B.to blame ourselves too much

C.to encourage ourselves to work hard

D.to give up ourselves

7.What is the author's purpose of writing this article?

A.To encourage people to make greater efforts.

Due to the outbreak of the novel coronavirus pneumonia （NCP）, people all over the world arc wearing masks to reduce the risk of infection. It's a very simple but incredibly effective method to protect oneself from a variety of harmful things. In fact, masks have been helping mankind for centuries. Let's take a look at some mask-related history.

1st century

In that era, many people in Roman Empire worked underground in mines to support their families. But most of them suffered from and even eventually died of respiratory （呼吸的） illnesses. To address this problem, Pliny the Elder （23-79 AD）, a Roman philosopher and naturalist, recommended the use of animal bladder （膀胱）skins to stop dust from being breathed in. Although primitive, his idea was considered the very first recorded mask invention.

16th century

Early inventions did not stop with Pliny. Many centuries later, Italian artist and inventor Leonardo da Vinci （1452-1519）, proposed using a woven cloth dipped in water over the face to protect against the poisonous chemicals.

19th century

The design of the mask look a big step forward in the 19th century. In 1848, American Lewis Hassley became the first person to patent （注册专利）a protective

mask for miners, which was a milestone in face mask history. Masks at this stage were similar to gas masks. Later, in 1897, Polish-Austrian doctor Johann von Mikulicz-Radccki designed a simple mask composed of one layer of gauze （纱中1）, recommending medical workers to wear it to prevent infection. That was the first recorded use of a surgical mask.

20th century

In 1910. an epidemic broke out in Northeast China. Chinese doctor Wu Liande designed a cheap face mask called "Wu's mask". Made of two layers of surgical gauze, it could be wrapped around the back of the head and tied in a knot. This mask was praised by experts around the world, as it was simple to manufacture （制作）and had a low production cost. Modem exploration

With several outbreaks of infectious diseases and the flu. and the rise of pollution caused by industrial waste, the materials in masks have continued to evolve to better protect its wearer. For example, in 2012 when China suffered from smog, mask models such as N95 and KN90. which can filter out this fine particulate （微粒）mailer, became highly popular. In the future. masks will continue to improve, hopefully so will the habits of humans.

8.According to the text, why were masks invented?

A.To reduce the risk of infection.

B.To protect miners from dust.

C.To indicate patients with respiratory illnesses.

D.To protect workers from harmful chemicals.

9.What was considered a milestone in face mask history?

https://www.wendangku.net/doc/2610859460.html,ing a woven cloth instead of animal skins.

B.Getting a patent on protective masks for miners.

C.The invention of surgical masks in 1897.

https://www.wendangku.net/doc/2610859460.html,ing more than one layer of surgical gauze.

10."Wu's mask" grew popular around the world because.

A.it could be used multiple times

B.it was simple for people to wear

C.it was cheap and easy to manufacture

D.it could better protect people from smog

11.What is the text mainly about?

A.The evolution of masks.

B.The benefits of using masks.

C.A comparison of different masks.

D.The roles masks played at different times.

During the outbreak of novel coronavirus, cities are locked down and borders are closed. Science, on the contrary, is becoming more open. And this "open science”is already making a difference.

Soon after the epidemic started in China, a research team from Fudan University in Shanghai successfully sequenced （测定序列）the DNA of the virus. But they didn't keep the information to themselves. Instead, they placed the sequences on GenBank, an open-access data platform, so researchers around the world could download them for free and start studying the virus.

Due to this openness, pharmaceutical companies across the globe arc now able to work at the same time to develop a vaccine （疫苗）."There may be room for multiple different vaccines for different purposes and different age groups,” Amesh Adalja, a senior scholar at the Johns Hopkins University Center for Health Security in the US, told Al Jazccra. "The bigger menu we have of vaccines, the more resilient （有适应力的）we'll be against coronavirus outbreaks in the future."

Major drug companies around the world arc also sharing their study results. Remdesivir, a drug originally developed by US company Gilead Sciences to treat Ebola, is found to be promising in fighting against the novel coronavinis. Currently, two trials of the drug arc already underway in China, and the results might be available as soon as April, according to The Verge.

This openness in science is going to be even more important in the future. “With climate change, increasing globalization, and population shifts, epidemics will not go away, and might even become more frequent,”Dan Barouch, a Harvard Medical School professor, told Harvard Magazine.

He said, “No one group can do everything. It has to be a coordinated approach. But I do think that the world has a greater sense of readiness this time to develop knowledge, drugs, and therapeutics （疗法）very rapidly.”

Every epidemic is indeed a crisis, but it can also be a learning opportunity. One redeeming （补偿的）factor of the COVID-19 outbreak is that it is helping science adapt for the better.

12.What does the article mainly talk about?

A.Coordinated efforts to fight the epidemic.

B.Something positive we've learned from the epidemic.

C.The significance of openness and sharing of scientific knowledge.

D.What needs to be done to prevent future epidemics.

13.What is the positive effect of the research team from Fudan University placing the genetic sequence of the virus onto GenBank?

A.They alerted the world to the danger of the virus.

B.They helped remove people's fear of the virus.

C.They showed the world how to produce a vaccine.

D.They invited collective efforts worldwide to develop a vaccine.

14.What is the author's purpose of mentioning Remdesivir in the text?

A.To introduce a possible cure for the epidemic.

B.To compare the treatment of Ebola and the novel coronavirus.

C.To prove that many drug companies readily share their discoveries-

E.To show that the novel coronavirus will soon be contained.

14.Which of the following would Dan Barouch probably disagree with?

A.Epidemics will be less frequent thanks to scientific development.

B.The world is becoming better prepared to deal with epidemics.

C.No single group can fight against the epidemics independently.

D.The increase in globalization may worsen future epidemics.

第二节（共5小题；每小原2分，漓分1吩）

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项.选项中有两项为多余选项。

How do you get yourself to take action now? Here arc some powerful suggestions.

Focus intensely on the positive things that your actions will accomplish. _16_ Whether it's something you're seeking to accomplish, or something you're seeking to be rid of. picture exactly how your life will be after the work is done. The more intensely you can imagine it, the better.

_17_ The only real reason you have for avoiding action is because you associate some kind of pain or discomfort with it. Therefore^ it helps to associate something even more painful with not taking action. Instead of focusing on the relatively minor pain of taking action, focus instead on the major pain of not taking action.

_18_ Think of all the reasons you can come up with to not take action, and then destroy all those reasons with a single word --"But." Simply state the excuse, put the word "but" after it, and then finish the sentence- For example, “I’ve never done this before, BUT I can learn." Stick the word "but" in there, and challenge yourself to finish the sentence.

Take the first small step. Don't even concern yourself with committing to the whole project or course of action. Just do something very easy and very small. The point is to find a little momentum（动力）_19_ Then climb aboard the momentum train, and let it help you keep the effort going.

Make it fun. Realize that just about anything can be fun if you'll think of it as fun and enjoyable. Find a way to make something fun, and not only will you want to do it; you'll also be better at it. _20_

A.You always choose what to do,

https://www.wendangku.net/doc/2610859460.html,y all your excuses out on the table and deal with them.

C.In your mind, picture in great detail what your actions will bring you.

D.Whatever you must do to achieve success, find a way to enjoy it.

E.Focus on the negative things that will happen if you don't take action.

F.Getting started with your biggest task or most difficult action may seem too much.

G.Once you take that small action, let yourself fully enjoy how great it feels.

2018年秋高二英语期中试题学生卷

高二英语期中考试题 一、阅读理解（共5大题；每小题2分，共40分） A On a Friday night, a poor young artist stood at the gate of the New York railway station, playing his violin. The music was so great that many people stopped to put some money into the hat of the young man. The next day, the young artist came to the same place, and put his hat on the ground gracefully. Different from the day before, he took out a large piece of paper and laid it under his hat. Then he began to play the violin. It sounded more pleasant than ever. Soon he was surrounded with people who were attracted by the words on that paper. It said, "Last night, a gentleman named George Sang put an important thing into my hat by mistake. Please come to claim（认领）it soon." After about half an hour, a middle-aged man rushed through the crowd to the violinist and said, "Yes, it's you. I knew that you were an honest man and would certainly come here." The young violinist asked calmly, "Are you Mr. George Sang?" The man nodded. The violinist asked, "Did you lose something?" "It's a lottery ticket （彩票）," said the man. The violinist took out a lottery ticket on which George Sang's name was seen. "Is it?" he asked. George nodded and took the lottery ticket and kissed it, then danced with the violinist. The violinist was a student at an arts college and had planned to attend advanced studies in Vienna. Later his classmate asked the violinist, "At that time you needed money to pay the tuition （学费）and you had to play the violin in the railway station every day to make money. Why didn't you keep the lottery ticket for yourself?" The violinist said, "Although I don't have much money, I live happily. But if I lose honesty I won't be happy forever." Through our lives, we can gain a lot and lose so much. But being honest should always be with us. 1.What did the young artist do at the railway station on Friday? A. He walked around the New York railway station. B. He waited for the train to Vienna. C. He came to buy a train ticket to Vienna. D. He played the violin to make some money. 2.Which of the following statements is true according to the words on the paper? A. The hat belonged to George Sang.
