21、What is the purpose of lightning? The new study published at the end of April in Science found that lightning may play a bigger role in global climate change than was previously known by the scientific community.
Many are familiar with the potentially deadly dangers posed by lightning, which is blamed for an average of 43 deaths in the United States each year, based on data from 1989 to 2018. Although the odds of being struck are quite low-1 in 1, 222, 000 in a given year and 1 in 15, 300 in a lifetime many in the weather community have long urged people to take proper precautions to stay safe in storms. However, the researchers recently uncovered a surprising and beneficial impact of lightning.
The study, which included contributions from nine atmospheric researchers across a dozen universities, was based on an airborne research flight conducted by a NASA DC-8 storm-chasing plane in 2012. Researchers initially thought there was a problem with the equipment on the plane, which was being used to measure the hydroxyl radicals (羟基自由基) in the atmosphere until they realized increases they observed corresponded with lightning flashes, ABC News reported.
Hydroxyl radicals, described as a “chemical scavenger (清洗剂) ” by Science Direct, are important chemical compounds found in the atmosphere due to the reactive nature with other organic molecules (分子). Researchers previously understood that lightning could help to clean the atmosphere, but there was no evidence that it could generate compounds like these radicals. “No one has seen that much in the atmosphere from natural processes, ever,” Brune said. As a result, the study estimates that somewhere between 2% and 16% of the oxidizing (氧化), or cleaning that happens naturally in the Earth’s atmosphere, is done by lightning.
Why is this significant? The oxidation process helps to reduce chemicals like carbon monoxide and methane in the atmosphere. These chemicals, known for being greenhouse gases, have been proven to contribute to rising temperatures associated with climate change. Researchers say that more studies will need to be conducted to verify the degree to which lightning contributes to the fight against global climate change.
【1】What do the statistics in Para 2 tell us about lightning?
A．It threatens human lives.
B．It can only harm people.
C．It is a strange phenomenon.
D．It happens quite frequently.
【2】What led to the new discovery in the text?
A．The equipment failure on the storm-chasing plane.
B．The increase of Hydroxyl radicals during lightning.
C．The lightning flashes observed by the research team.
D．The airborne research conducted by NASA scientists.
【3】How does Brune feel about the finding?
A．Doubtful.
B．Amazed.
C．Frustrated.
D．Ambiguous.
【4】What is the main idea of the text?
A．Hydroxyl radicals clean the atmosphere.
B．Oxidizing is a natural result of lightning.
C．Lightning may help address climate change.
D．Greenhouse gases contribute to rising temperature.
22、Food picked up just a few seconds after being dropped is less likely to contain bacteria than if it is left for longer periods of time, according to the findings of research carried out at Aston University's School of Life and Health Sciences. The findings suggest there may be some scientific basis to the '5 second rule' --- the belief about it being fine to eat food that has only had contact with the floor for five seconds or less. Although people have long followed the 5 second rule, until now it was unclear whether it actually helped.
The study, undertaken by final year Biology students and led by Anthony Hilton, Professor of Microbiology at Aston University, monitored the transfer of the common bacteria from a variety of indoor floor types such as carpet, cement floor to toast, pasta, biscuit and a sticky sweet when contact was made from 3 to 30 seconds. The results showed that: Time is a significant factor in the transfer of bacteria from a floor surface to a piece of food; and the type of flooring the food has been dropped on has an effect, with bacteria least likely to transfer from carpeted surfaces and most likely to transfer from cement flooring surfaces to moist foods making contact for more than 5 seconds. Professor Hilton said: "Consuming food dropped on the floor still carries an infection risk as it very much depends on which bacteria are present on the floor at the time.”
The Aston team also carried out a survey of the number of people who employ the five-second rule. The survey showed that: 87% of people surveyed said they would eat food dropped on the floor, or already have done so. 55% of those that would, or have, eaten food dropped in the floor are women. 81% of the women who would eat food from the floor would follow the 5 second rule. Professor Hilton added: "Our study showed surprisingly that a large majority of people are happy to consume dropped food, with women the most likely to do so. But they are also more likely to follow the 5 second rule, which our research has shown to be much more than an old wives tail."
【1】 Eating food dropped on the floor still carries an infection risk because it relies on________ at that time.
A. the type of bacteria B. the carpet
C. the cement floor D. the surface of table
【2】The passage is developed probably by __________.
A. time B. space C. contrast D. example
【3】How did Professor Hilton feel after analyzing how many people chose to eat dropped food?
A. Satisfied B. Astonished
C. Puzzled D. Upset
【4】What is the main idea of this passage?
A. The food which is dropped on the floor can be eaten safely.
B. The bacteria have no negative effect on the safety of food.
C. A research on the safety of food dropped on the floor is undertaken.
D. People surveyed in the research are willing to accept the idea.
23、In the past, if a person wanted to see the national treasures of a country, one had to go there in person．Therefore, very few people were able to enjoy some of history’s most important and interesting artifacts (手工艺品)．This has changed with an increase in the number of traveling museum exhibitions．
King Tutankhamen Artifacts
A traveling exhibition of artifacts from the tomb of King Tutankhamen, popularly known as “King Tut”, toured the United States from November 1976 to April 1979．The 55 objects were shown in six cities and were seen by around eight million museum-goers．The second touring exhibit was started in 2007, this s antime with 130 artifactd stops in London and three different American cities．However some objects, like the king’s golden face mask, are too valuable or too delicate to be transported long distances, so “replicas” (exact copies of something) are on show．
Japanese Color Woodblock Prints
The Art Museum at University of Virginia, in Charlottesville, Virginia, has an extraordinary collection of Japanese color woodblock prints (木刻版画)．These prints document the period from about 1850 to 1900, a time when Japan was opening itself to Western influences．Before this point, Japan was a closed society that had little communication with the world outside of its borders．These works of art beautifully show the feeling of change and the trend toward modernization．The museum has put together a traveling exhibition of 60 of these prints, which can be borrowed and exhibited worldwide for periods of eight weeks or more．
Face-to-face with “Lucy”
One of the world’s most famous archaeological (考古学的) finds in history are the 3．2 million-year-old bones of a 106-centimeter-tall female found in the Ethiopian desert in 1974．Lucy, a name given to her by the discovery team, is a “hominid”, or a creature that scientists believe is the earliest ancestor of modern human beings．Rarely is an artifact this valuable allowed to travel widely, but Lucy has been taken to several museums in the U．S．while a detailed replica remains at the Ethiopian Natural History Museum．
【1】What do we learn about King Tutankhamen’s artifacts?
A． The artifacts were shown in London first．
B． The artifacts were on show in the United States once．
C． The second touring exhibit showed more artifacts than the first one．
D． The king’s golden face mask was also shown in the traveling exhibitions．
【2】What do the Japanese woodblock prints show about the society from 1850 to 1900?
A． Japan had little communication with other countries．
B． The whole country refused changes in the society．
C． Japan was opening itself up to Western ideas．
D． Japan achieved modernization．
【3】Who is Lucy according to the passage?
A． An archaeologist．
B． The ancestor of modern human beings．
C． A 106-centimeter-tall female who died in 1974．
D． The first woman who visited the Ethiopian desert．

25、Bringing Mosquitoes Under Control
Every year, hundreds of thousands of people die of mosquito-borne diseases like malaria and dengue fever. Drug treatments are ________, and, despite decades of effort, vaccines have, for many of these diseases, proven to be difficult to develop.
It is better, then, to stop these infections happening in the first place by ________ doing away with the mosquitoes that carry the diseases. CRISPR-Cas9, a new and powerful genetic-engineering process, could help to do just that.
Craig Montell, of the University of California, and his colleagues have used CRISPR to ________ an existing control method called the sterile insect technique (SIT), which involves releasing lots of sterilized (绝育的) males into the wild. Females that mate with these males produce no young. ________ releases can reduce populations dramatically. SIT has been used in North America to eliminate screwworm flies, an agricultural pest.
SIT has been tried on mosquitoes, too, but with less ________. One reason seems to be the side-effects of the procedure. To sterilize them, males are exposed to poisonous chemicals. This works, but it damages them in other ways, too. The result can be sickly individuals that ________ to compete in the mating game with wild mosquitoes.
Montell and his colleagues hoped that CRISPR might offer a(n) ________. Their first step was to look for genes which affect fertility (可繁殖性) in mosquitoes. They began their hunt in fruit flies and ended up focusing on a gene that, when ________, made male fruit flies sterile. The gene was present in a similar form in their target mosquito species, Aedes aegypti, which passes on, among other illnesses, yellow fever, dengue and the Zika virus. Disabling the ________ gene in male Aedes likewise left them infertile. ________, the genetic changes involved did not appear to affect the engineered mosquitoes in any other way. On every measure of ________, they performed as well as wild mosquitoes.
________ the details are not fully understood, once female mosquitoes have mated a few times, they become unwilling to do so again. Mating with an infertile male is, therefore, not only fruitless in itself, but should also leave a female less interested in ________ males.
There is more work to be done before field trials, but having established the ________, Montell is excited to see where the work might lead. That the engineered males leave no young means that there are fewer worries surrounding any ________ consequences which might arise from the release of millions of genetically edited creatures into the environment. And that the target gene is found in both fruit flies and Aedes suggests it is likely to exist in other disease-carrying mosquitoes, too.

26、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。
As 17-year-old Torriell Norwood drove through St. Peters-burg, Florida last February with her friends to pay a visit to the great park as scheduled. Norwood shared her first aid courses and her dream of becoming a doctor and other girls shared their precious experiences about the natural adventures with each other. The laughter and chatter from the four teenage girls inside her car quickly gave way to screams. As they approached an intersection, another car T-boned them, sending their black car sailing into the yard of a nearby home, coming to a stop only when it crashed into a tree. All of them were in panic instantly, totally at a loss!
As smoke waved from the car, a bystander shouted, “It’s about to blow up! Get out!” The impact had caved in Norwood’s driver’s side door, jamming it shut. The bystander seized the front door handle of the car, summoned all his strength to pull it open but failed. Shaken, but otherwise OK, Norwood crawled out through the window. She had a cut on the right side of her face. Originally her lovely face became very pale. Along with two of her friends, who’d also managed to free themselves, she ran for her life.
But halfway down the street, she realized that her best friend, Azarria Simmons, was not with them. Norwood ran back to the wreck and found Simmons slumped in the back seat. “She was not moving,” Norwood shouted with her heart tightened. She threw open the back door and pulled her friend out, avoiding the broken glass as best she could. She dragged Simmons a few feet to safety and laid her on the ground. She checked her pulse. Nothing! She put her head against Simmons’s chest. No sign of life!
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。
If the accident had happened a few weeks earlier, she might not have known what to do.
____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________
