1 . Cheating in sport is as old as sport itself. The athletes of ancient Greece used potions to strengthen themselves before a contest, and their modern counterparts have everything from anabolic steroids (类固醇) to growth hormones with which to_________their bodies. These days, however, such stimulants are_________, and those athletes must therefore face the challenges of anti-doping (反兴奋剂) agencies.

The agencies have had remarkable success. Testing for anabolic steroids was introduced in the 1970s, and the incidence of cheating seems to have_________dramatically as a result. The tests, however, are not entirely_________. And a study just published in the Journal of Clinical Endocrinology & Metabolism by Jenny Jakobsson Schulze and her colleagues at the Karolinska Institute in Sweden suggests that an individual’s genetic make-up could_________the tests in two different ways. One genotype, may allow athletes who use anabolic steroids to escape detection altogether. Another may actually be convicting (给……定罪) the innocent.

The test employed for testosterone (睾酮素) abuse usually relies on measuring the_________of two chemicals found in the urine (尿液): TG. and EG.. Any ratio above four of the former to the latter is considered_________and leads to more tests. However, the production of TG is controlled by a gene called UGT2B17. This gene comes in two varieties, one of which has a part missing and therefore does not work properly. A person may thus have none, one or two working copies of UGT2B17, since he inherits one copy from each parent. Dr. Schulze_________that different numbers of working copies would produce different test results. She therefore gave healthy male volunteers whose genes had been examined a single 360mg shot of testosterone — the standard dose for legal medical use — and checked their urine to see whether the shot could be_________.

The result was remarkable. Nearly half of the men who carried no functional copies of UGT2B17 would have gone undetected in the standard doping test.____________, 14% of those with two functional copies of the gene were over the detection threshold (门槛) before they had even received an injection. The researchers estimate this would give a ____________rate of 9% in a random population of young men.

Dr. Schulze also says there is substantial____________variation in UGT2B17 genotypes. Two-thirds of Asians have no functional copies of the gene which means they have a naturally____________ratio of TG to EG, compared with under a tenth of Caucasians (白种人) — something the anti-doping bodies may wish to take into account.

In the meantime, Dr. Schulz’s study does seem to offer innocents a way of____________themselves. Athletes who will travel to Paris for the Olympic games may be wise to travel armed not only with courage and the “spirit of Olympianism”, but also with a copy of their____________, just in case.

2 . The public must be able to understand the basics of science to make informed decisions. Perhaps the most dramatic example of the negative consequences of poor communication between scientists and the public is the issue of climate change, where a variety of factors has contributed to widespread mistrust and misunderstanding of scientists and their research. The issue of climate change also illustrates how the public acceptance and understanding of science (or the lack of it) can influence governmental decision-making with regard to regulation, science policy and research funding.

However, the importance of effective communication with a general audience is not limited to hot issues like climate change. It is also critical for issues such as the genetic basis for a particular behavior or the use of animal models because in these areas, the public understanding of science can also influence policy and funding decisions. Furthermore, with continuing scientific advances, more non-scientists will need to be able to analyze complex scientific information to make decisions that directly affect their quality of life.

Science journalism is the main channel for the popularization of scientific information among the public. Much has been written about how the relationship between scientists and the media can shape the efficient communication of scientific advances to the public. Good science journalists are specialists in making complex topics accessible to a general audience, while sticking to scientific accuracy. Unfortunately, pieces of science journalism can also oversimplify and generalize their subject material. As a result, the basic information conveyed is difficult to understand or obviously wrong.

Even though scientists play a part in conveying information to journalists and ultimately the public, too often the blame for ineffective communication is placed on the side of the journalists. I believe that, at least in part, the problem lies in places other than the interaction between scientists and members of the media. It exists because we underestimate how difficult it is for scientists to communicate effectively with a diversity of audiences, and most scientists do not receive formal training in science communication.

1. What does the example of climate change mainly serve to show?

A．Adequate government funding is vital to scientific research.

B．Government regulation helps the public understand science.

C．The public’s scientific knowledge can influence policy making.

D．There is widespread public mistrust and misunderstanding of scientific work.

2. Why is it important for scientists to build a good relationship with the media?

A．It helps scientists to build a better public image.

B．It helps them to effectively popularize scientific information.

C．It enables scientists to better apply their findings to public health.

D．It enables the public to develop a positive attitude toward science.

3. What is the problem with some pieces of science journalism?

A．They give inaccurate or complicated information.

B．They oversimplify people’s health problems.

C．They fail to mention the scientific advances.

D．They lack detailed information about scientific research.

4. According to the writer, what should scientists do to communicate to the public more effectively?

A．Interact more with the media.

B．Give training to science journalists.

C．Improve their communication skills.

D．Arouse the public’s interest in science.

3 . Whether you’re in the final research stages of a major paper, or on a Zoom (a calling app) call for work, a dropped WiFi connection at zero hour is something annoying.     1     One of the most common reasons it happens is that too many devices are connected.

    2     Now, with smartphones, iPads, smart TVs and so much more, it doesn’t take long for WiFi to hop aboard the struggle bus. Actually, even if a connected device isn’t actively sending or receiving data, it will still consume some of the available bandwidth. It means that if you have many devices connected, you can start to see slowdowns or drops in your WiFi connection.     3    

The first and easiest fix is to disconnect unused devices from your WiFi. The easiest way to do this is to simply change your WiFi password, which will kick everyone off. Then, you can allow only certain devices to rejoin.     4     It is workable to stop gaming or downloading a movie.

    5     First, run a speed test to check your current speed. (Google “speed test” to see a list of websites where you can do this.) You may have too many devices connected for the internet speed you’re paying for. If this is the case, contact your internet provider about upgrading to a higher speed. But you may want to try some of our other fixes first before spending the money.

A．What can you do about it?

B．Sometimes that’s all that’s required.

C．Finally, you may need to upgrade your connectivity.

D．People deal with this modern inconvenience all the time,

E．Cutting back on heavy WiFi use temporarily can also help.

F．In general, this is a very good solution to a dropped WiFi connection.

G．Back in the day, the average household had a computer or two to connect.

4 . Types of Maps

Different types of maps have different uses. Tourist maps, for example, have signs to show places of interest in an area. When tourists read these maps, it is easy for them to find where to go and what to see in a place and it is easy for them to go and find their ways to these places.

Road maps show large areas so that people can plan long journeys. Different types of roads are given different numbers. For example, if you want to go to Wood Green, you just follow No. 621 Road and keep looking at the road signs.

Distribution maps use colors or signs to show facts about an area. For example, where different languages are spoken, how many people live in an area, how cold and hot some places are, or whether a place is short of water.

Some maps, such as railway maps, use straight lines to show everything. This is easy for people to read. Trains are fast. People don’t have to think about small places they go past. They just need to know the two ends of their trips.

1. How can you tell different roads on road maps?

A．By using different colors.	B．By finding the numbers.
C．By following No. 621 Road.	D．By looking at the road signs.

2. Which of the following can distribution maps tell us?

A．How to get to Germany.	B．How to plan a long journey.
C．Where a famous museum is.	D．Which place is short of water.

3. Why do railway maps use straight lines?

A．Because railways are straight.

B．Because people like straight lines.

C．Because people can read them easily.

D．Because railways have only two ends.

5 . My grandfather was a rigid perfectionist. Everything had to be orderly, precise and punctual. I was frightened of him until the day he died. Growing up, my mother desperately wanted to please him. She probably thought he might leave if she didn’t.

In fact, I now think the fear of being left alone, abandoned, was a current throughout much of her life. A few years into my father suffering from Alzheimer, my mother’s voice on the phone sounded so upset that I had to tell her, “Just be with yourself for a little while.”

“No, I can’t do that. I don’t want to do that,” she said abruptly, closing the door on the subject. A while after my father died, she told me that she kept the television on all the time because it made her feel less lonely. “It makes the house seem more lived in,” she said. I had given in to my annoyance and either turned the volume down or turned it off. But after she told me that it filled in some of the loneliness, I never reached for the remote again.

We have had a long journey together, she and I. Over a half-century of memories, now that the journey has ended, I have a choice which ones to study which ones to turn over in my hands and dust off.

I choose to look at the ones that ache with a sweet truth not told often enough: there was love between us. It was just hard to find sometimes. I choose to remember her face on that winter day in Manhattan, when I came to her with a broken heart. I choose to remember walking on the shore with her in summers when we rented a beach house; somehow the sea always transformed us. And how she looked on my wedding day when she handed me a bracelet that had belonged to my grandmother. “Something old,” she said.

3. The author writes the story to ________.

A．express regret for her grandfather

B．show her sympathy toward her mother

C．reveal her deep feelings for her mother

D．emphasize her concern about the generation gap

6 . The discovery of the ruined palace in the Mosul Dam reservoir on the banks of the Tigris River inspired an archeological dig that would improve understanding of the Mittani Empire, one of the least-researched empires of the ancient Near East, a team of German researchers said. “The find is one of the most important archeological discoveries in the region in recent decades,” Kurdish archeologist(考古学家) Hasan Qasim said.

The palace would have originally stood just 65 feet from the river on a terrace(梯田). A terrace wall of mud bricks was later added to make the building stable. Ivana Puljiz, an archeologist from the University of Tübingen’s Institute for Ancient Near Eastern Studies, describes the palace, known as Kemune, as a carefully designed building with mud-brick walls up to 2 meters (6.6 feet) thick.

The team also found wall paintings in shades of red and blue, which were probably a common feature of palaces at the time but have rarely been found preserved. “Discovering wall paintings in Kemune is an archeological sensation,” Puljiz said in a press release, “Kemune is only the second site in the region where wall paintings of the Mittani period have been discovered.”

Ten clay tablets covered in cuneiform, an ancient system of writing, were also discovered and have been sent to Germany for translation. “From the texts we hope to gain information on the inner structure of the Mitani Empire, its economic organization, and the relationship of the Mittani capital with the administrative centers in the neighboring regions,” Puljiz added.

Archeologists first became aware of the site in 2010 when water levels in the reservoir were low, but this is the first time they have been able to dig. However, the site was submerged(淹没) shortly after the dig, Puljiz said, adding“It is unclear when it will come out of water again”.

1. The function of the archeological dig is to ________.

A．attract people to travel to the Tigris River

B．help people know the Mittani Empire better

C．show ways of rebuilding the Mosul Dam reservoir

D．provide some clues about research on the Near East

2. Why was the mud-brick terrace wall built later?

A．To make the palace firmly built.	B．To offer tourists a place for rest.
C．To give tourists a good view.	D．To make the building better designed

3. What can we infer from Puljiz’s words in paragraph 3?

A．Kemune is different from any other palace.

B．Wall paintings were an important discovery.

C．Kemune is famous for its special wall paintings

D．Wall paintings were first discovered in the Mittani Empire.

4. What made the dig difficult for archeologists?

A．Translating the cuneiform into English	B．Knowing relationships between regions.
C．Waiting for the water level to drop.	D．Understanding the structure of the empire.

7 . 站在桌旁的是他的妻子。

8 . 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。

Be yourself and always follow your heart. Never let anyone change who you are. This is the lesson I have learned from my childhood experience when I figured out I wasn’t invited to the party, Bridget’s party.

One morning, I got off the bus and saw my friends except me hugging under the tree where we used to stand. The circle seemed tighter as I approached；the white invitation cards being hastily stuffed into backpacks gave it away. I knew as well as the entire universe that Bridget’s party was this weekend. Bridget was the most popular girl in our class. She was thin and beautiful, always wearing fabulous clothes and fine makeup.

Why hadn’t she invited me? My feet were too big? No. Maybe. My face was broken out? Why did she invite every person in my group except me? I tried to think of any interactions I’d had with Bridget recently. A few days earlier, we’d been partners during a sixth period project. I was determined to get the project done and she was absorbed in looking at fashion magazines. She barely spoke to me except to say, “You’re so serious. You know, you should smile more."

Soon, I had overheard all the details about the party. They were going swimming. It was a sleepover. They were renting scary movies and were going to stay up all night. Each time someone mentioned the party, I smiled weakly and nodded, with my stomach in knots.

When having my favorite English class, I found myself just unable to concentrate on the short stories we were supposed to be reading in class. Maybe she didn’t invite me because of my coat. It is pretty ugly compared to some of the other girls’ coats. I should have bought another color. Maybe I should smile more but I just can’t get into smiling at people unless I know them really well. But I just couldn’t pretend to be the person I wasn’t. I felt sick.

注意：

At lunch, my friend Kate who had been invited came over to me, trying to show off.

10 . 阅读下面材料，在空白处填入1个适当的单词或括号内单词的正确形式。

With the International Conference on Food Loss and Waste closed on Saturday in Jinan, Shandong Province, the country has sent a signal to     1     world that China will deal with issues concerning food security by reducing loss and waste in agriculture. With the theme of reducing food loss and food waste and promoting     2     (globe) food security, the three-day event     3     (hold) both online and offline attracted more than 300 participants.

The current world grain production is about 2.8 billion tons a year. Therefore, the loss of only one percentage     4     (be) equal to the loss of 28 million tons of food. This can feed about 70 million people.

In recent years, China     5     (make) great progress in controlling loss and waste in food, with main efforts including upgrading facilities and     6     (equip). In Shandong Province, China’s major grain producer, the Sinograin (中粮集团) grain storage site is equipped with 4,500 high-definition cameras and 280,000 temperature sensors     7     (ensure) that the stock (储备) is in the best condition. Data shows that during China’s 13th Five-Year Plan period (2016-2020) , about 13 million tons of food had been saved     8     (year) after production.

We cannot end hunger     9     we do not deal with the high levels of food loss and waste. Cooperation and innovations (创新) in business models, technologies and digital solutions could all contribute     10     reducing food loss and waste.
