26、The Nobel Prize is considered one of the most recognizable and admirable awards possible, honoring people of the world for their outstanding achievements in different fields.
Alfred Nobel was born in 1833 to a family of engineers in Stockholm, Sweden. In 1850, he met Ascanio Sobrero, the inventor of nitroglycerin (硝酸甘油)in Paris. Interested in its unpredictable nature of exploding under pressure or heat, Nobel started to find a way to control it and make a usable explosive(炸药). After years of efforts, in 1867, at the age of 34, Nobel invented dynamite(炸药), which is much easier and safer to control than nitroglycerin.
During his lifetime, Nobel invented and patented various explosives. He built up his wealth from his 355 inventions, from which dynamite was the most important.
When Alfred's brother Ludwig died in 1888, a French newspaper mistakenly published Alfred's obituary(讣告). Reading his own obituary, Nobel was disappointed to find out his public image. The newspaper strongly blamed(责备) Nobel for inventing dynamite, giving him the nickname of “the merchant of death” and saying “Dr. Alfred Nobel, who became rich by finding ways to kill more people faster than ever before, died yesterday.”
To Alfred, this obituary was a warning. He spent his lifetime alone inventing things and was deeply concerned with how he would be remembered. This unfortunate event inspired him to make changes in his will, so as to improve his public image, and to be remembered for a good cause. In 1895, one year before his death, Nobel made the last will, saying clearly that his wealth would be used to create a series of prizes for those who have made great contributions to mankind in physics, chemistry, physiology or medicine, literature, and peace. To widespread astonishment, Dr. Alfred Nobel gave away 94% of his total wealth to found the five Nobel Prizes.
【1】What led to Nobel's invention of dynamite according to paragraph 2?
A.The strong desire to make money.
B.The valuable help from his family.
C.His lifetime dream of achieving success.
D.His great curiosity and devotion to science.
【2】What was Alfred Nobel's attitude towards the newspaper's obituary?
A.Upset.
B.Satisfied.
C.Optimistic.
D.Supportive.
【3】Why did Nobel give away most of his wealth to set up the Nobel Foundation?
A.To leave a good name to the public.
B.To prove the importance of his inventions.
C.To publish his findings of scientific research.
D.To be remembered as “the merchant of death".
【4】Which of the following was a surprise when Nobel founded the prizes?
A.He set so many awards.
B.He gathered so much wealth.
C.He donated nearly all his property.

27、In April this year.China successfully launched(发射)the Tiangong space station. It is expected to be ready next year in 2022. However. a long queue of experiments from around the world are already in place for flight. CMSA (China Manned Space Agency) has approved a plan of more than 1.000-such experiments. several of which have already been launched. The research topics range from studying dark matter to cancer research and studying disease-producing matter.
Before Tiangong was launched. the ISS (International Space Station) was the only space laboratory in place. The addition of Tiangong has been welcomed by several scientists and researchers from across the world.
Julie Robinson. chief scientist for human exploration and operations at NASA Headquarters. said."Increased scientific access to space is of scientific benefit globally. no matter who builds and operates platforms."
The views of Agnieszka Pollo. a scientist at the National Centre for Nuclear Research in Warsaw. were similar."We need more space stations. because one space station is definitely not enough."
Since its launch in 1998. the ISS provided equipment to conduct over 3.000 experiments to scientists from different countries. However. China was not allowed to conduct any such experiment due to a US rule which forbids NASA from cooperating(合作) with China.
On the other hand. Tiangong is welcoming experiments from all countries. including the US. Reportedly. CMSA selected nine experiments to be carried out on Tiangong in June 2019. These nine experiments were in addition to a thousand other experiments that China has approved to go up to the space station. These will include 23 organizations from 17 nations.
【1】What can we say about the research topics approved by CMSA?
A.Fewer but better.
B.Not carefully selected.
C.Various but disordered.
D.Various and useful.
【2】Why did the author mention Julie Robinson and Agnieszka Pollo?

B.To explain why Tiangong is welcome.
C.To compare Tiangong with the ISS.
D.To show how special Tiangong is.
【3】What can we know about the Tiangong space station?
A.It is a sharp contrast to the ISS.
B.It refuses any cooperation with US.
C.It is controlled by the United Nations.
D.It will welcome experiments from all countries.
【4】In which section of a newspaper may this text appear?
A.Education.
B.Science.
C.Health.
D.Culture.
28、Scientists have created a scent(气味)-delivery system that releases a pleasant fragrance when you sweat. Apply it to your skin, and the more you sweat, the better you’ll smell. That’s because the perfume only gets released upon contact with moisture(湿气).
Chemists from Harvard University combined two compounds(化合物) to create their new system. One chemical is alcohol-based. This is the nice-smelling perfume. The other chemical is an ionic liquid(离子性液体), which is a type of salt that is liquid at room temperature. Ionic liquids are made of ions---molecules that have lost or gained one or more electrons. If the molecule loses electrons, it will have a positive charge. If it gains electrons, it gets a negative charge. Ionic liquids contain the same number of positive and negative ions, which makes them neutral(中性的), with no overall electric charge. In general, ionic liquids have no smell.
When the perfume and ionic liquid are mixed together, a chemical reaction occurs. This bonds the molecules to each other. The reaction also temporarily inactivates(使不活跃) the perfume’s molecules. So when applied to the skin, the new perfume has no scent in the beginning. But adding water or sweat breaks the bond between the molecules. That releases the scent into the air.
“The rate of the release of the fragrance depends on how much you sweat, in other words, how much water is available,” explains chemist Nimal Gunaratne from Harvard University, who led the research. “Sweat is like the command to let the fragrance go.”
Christian Quellet is a chemist who has worked in the perfume industry for a long time. He is now an independent consultant based in Switzerland. “Gunaratne’s perfume opens the door to new developments and applications of fragrance controlled-release systems,” he says. Controlled-release systems allow small quantities of some compounds that they hold to enter the environment slowly.
The system also traps some chemicals in sweat that are responsible for the bad sweat smell. These compounds are called thiols (硫醇). Just as water does, thiols break apart the bond that ties the perfume to the ionic liquid. When this happens, the thiols attach to the ionic liquid and their bad scent is inactivated as the perfume had been. This means the water in sweat and its thiols are both able to release the fragrance from the newly developed perfume.
【1】Which of the following makes the scent delivery system special?
A. When it releases scent can be well controlled.
B. No perfume is required in the system.
C. The scent can last for a long time.
D. Sweat can help release the scent.
【2】The scent is released into the air when ________.
A. the perfume comes into contact with the skin
B. the perfume and ionic liquid contact each other
C. the perfume’s molecules are inactivated by water
D. sweat activates the molecules of the perfume in the mixture
【3】What Nimal Gunaratne says in Paragraph 4 suggests that with this scent-delivery system _____.
A. the more you sweat, the better you will smell
B. the perfume can’t always cover the bad smell.
C. how much water is available doesn’t matter much
D. how you smell depends on how much perfume you use
【4】What is Christian Quellet’s attitude towards Gunaratne’s new perfume?
A. Indifferent. B. Favorable. C. Doubtful. D. Critical.

31、根据课文内容及所给英文首字母提示,写出完整的单词。
During the Middle Ages, the p【1】 of Western art was to teach people about Christianity. T【2】, artists were not interested in painting r【3】 scenes. Their works were often p【4】 and two-dimensional, and the main c【5】 were often made much larger than everyone else to show their importance. This began to change in the 13th century with Giotto di Bondone (1267-1337). While his paintings still had r【6】 themes, they showed real people in a real environment. In p【7】, his paintings are set a【8】 f【9】 other paintings by their realistic human faces and deep emotional i【10】.
32、阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
On my first day in college, I was filled with worry and anxiety. I have heard that college is quite different from high school. Before school started, I became concerned about taking courses for credits, which would determine whether I could graduate on time. I also worried about getting along with my classmates and the rules and regulations of the school.
I was not used to changing from high school to college, which is why I was a little scared when I went into the building. I saw so many students that I did not know. I was surprised that we have class all day and there are around 150 students in one lecture class. I went to my first class really early so that I could get a seat close to the teacher to record the class and meet my classmates. Fortunately, there were some students that I knew from high school. Therefore, the class was not so scaring any more and everything seemed to be better than before.
Now is another thing. I did not realize that college students can wear whatever they want and it doesn’t matter with the uniform. But except for one, which is about your ID. You have to wear it when you are in college. If you don’t, you won’t be allowed to have the class, so it is totally different from high school. Related to this, the college contains only two sections for one morning, each lasting two hours. We have fifteen minutes for having the break time. That day, on my way to the next class, I tried to make new friends with the other students. After the morning class, I had lunch with my classmates. Most of my classmates are from the other provinces, which gives us a lot to talk about.
注意:1. 续写词数应为150左右;
2. 请按如下格式在答题卡的相应位置作答。
After lunch, we went to the library to look for some documents.
