Travel Guide to Hangzhou，a Paradise on Earth
Hangzhou is now in the spotlight as the main host of the 19th Asian Games．The capital city of East China's Zhejiang Province，is one of the seven ancient capitals of China．Here are some highlights of the city you can't miss．
West Lake
West Lake is definitely a place people can never miss when visiting Hangzhou．It is situated in the center of the city，with convenient public transport access．The Hangzhou government also offers free public bikes for tourists to travel around the lake．The parks around the lake are all free to visit．
Six Harmonies Pagoda
Standing on Yuelun Hill，on the north bank of the tidal Qiantang River，the Six Harmonies Pagoda is another masterpiece built during the Wuyue Kingdom—this one designed to conquer flooding from the Qiantang River．The name Six Harmonies was given to characterize its purpose of restoring the balance between the heavens and earth，as well as north，south，east，and west．It was erected in the hope of combating the “evil” river's tidal action．Today，the 13-storey pagoda commands a spectacular view of the Qiantang River．
The Xixi Wetland Park
Xixi，located less than five kilometers from West Lake in the west of Hangzhou，is China's first national wetland park．Environmental degradation is threatening wetland worldwide，and more than half of the country's inter-tidal wetland has also vanished，which makes the 226 plant species，50 kinds of fish and aquatic animals as well as 126 kinds of birds in Xixi even more valuable．Its native vegetation consists of subtropical mountainous swamp and evergreen and deciduous，broad-leafed forest．
Leifeng Pagoda
On the south of West Lake，Leifeng Pagoda is considered the top scenic structure around West Lake due to its stunning silhouette in the glow of evening．For almost a thousand years the pagoda withstood fires and wars，but finally fell down in 1924．

The Jones-Baldwin family wasn't always so big．When Keia Jones married her husband Richardo Baldwin in 2010，she had just one child: a 2-year-old daughter，Zariyah from a previous relationship．Little did they know，though，that their family would eventually add not one，not two，but three more children to the Jones-Baldwin family，thanks to the gift of adoption．
First came 11-year-old Karleigh，in 2014．She and Zariyah became close friends at school，but due to some financial difficulties，Keia says Karleigh's mother fell on hard times and was unable to properly care for her．In 2017，the couple adopted a lovely 3-year-old named Ayden．That same year，their fourth child came into their lives unexpectedly．
“Unlike our three other black kids，the baby，named Princeton，is white，” Keia recalls．Princeton was born seriously ill and stayed in hospital several weeks after his birth．“They needed someone to do skin-to-skin with him，” says Keia，“and chose me for the task，and I was more than willing to take on the job．”
The experience of being black parents raising a white son has certainly caused them some trouble．There are always lots of suspicious stares and unfavorable comments wherever they go．Someone even called the police and said the baby was stolen by the couple．Once the family were enjoying themselves on the beach in Florida when the police were called in．It was not until Keia showed the police their ID cards that they were convinced that the baby was indeed their adopted son．
When asked why they would make so much effort to adopt the kids，Keia smiled．“It's all love，” she said．“Both my husband and I love kids．We just can't stand seeing kids suffering．Thank goodness，the lovely kids，who are from different cultures and of different ages，are all growing up healthily and happily under the same roof．Over the years，they have brought us so much joy! Our hearts are so full and so grateful．”

C．Six． D．Seven．
5．Why was Karleigh adopted

6．What is some people's attitude to the couple raising Princeton

C．Optimistic． D．Doubtful．
7．What can we learn from the last paragraph

C．The kids adopted were from the same family．

C
The public nowadays has a misunderstanding of forest fires，believing that fires should be kept out of every type of forest．Many of us can recall Smoky the Bear's famous warning: “Remember，only YOU can prevent forest fires．”However，that's not always the case．Under the right conditions，and when conducted safely，fire can create many environmental benefits as well as help prevent larger，uncontrollable wildfires．
After a forest fire，many wildlife species will move into recently burned areas to feed on these newly available foods．Some reptiles and amphibians such as the pine snake prefer forests frequently burned by fire．As Herbert Stoddard put it，“One of the most harmful things modern man has done to birds has been his attempt to exclude fire from fire-type pine forests．Within a few years most forests choke up with bushes，lose their prairie-like vegetation (草原般植被) and can no longer support birds dependent on periodic burning for their food supply and proper cover．”
If you are asked to picture the forest floor，what do you see Pine needles，cones，leaves，branches might come to mind—all sources of fuel．If these fuel sources build up without any type of removal，the ‘fuel load’ can lead to fires catastrophic to forests and people alike．In contrast，prescribed fire can be used by forest professionals every couple of years to keep forest fuels at an appropriate and manageable level．They can also minimize the spread of pest insects and disease and remove unwanted tree and plant species．Plus，they can create and maintain important wildlife habitats rich in grasses and promote the growth of trees，wildflowers and other various plants．
Many organizations and agencies work to promote fire on the landscape when and where appropriate．Smoky Bear even has an updated warning: “Only You Can Prevent Wildfires，” as the Forest Service has over the last few decades developed policies and procedures to include prescribed fire as a management tool，as well as continuing their work to prevent and fight wildfires．
8．Why did the author mention Smoky the Bear's warning
A．To introduce the topic of the passage．
B．To clarify a misunderstood concept．
C．To show the significance of fire prevention．
D．To raise people's awareness of forest protection．
9．What can benefit birds according to Herbert Stoddard
A．Forest bushes．　　 B．Fuel sources．
C．Pine forests． D．Periodic burning．
10．What is the purpose of prescribed fire
A．To put out wildfires．
B．To keep the forest balance．
C．To remove tree and plant species．
D．To keep the fuel rich in the forest．
11．What might be the best title for the passage
A．One Match Can Start a Forest Fire
B．Where There Is Smoke There Is a Fire
C．Not All Forest Fires Are Created Equal
D．Why Not Keep the Forest Fire Burning
D
High school students perform better on tests if they are in a classroom with a view of a green space，instead of a windowless room or a room with a view of built-up space，according to a research from the University of Illinois Department of Landscape Architecture．
“It is the first to show a relationship between studying with a green view and students' performance，”said William Sullivan，the head of the research team．It's a significant finding that if you have a green view outside your window，you'll do better on tests． Sullivan hopes the results of their research will lead to policy changes．Changes in school design，for example, “it would be a much better thing than any of the things we spend money on in secondary education today，”Sullivan said．
The research included 94 students at five central Illinois high schools． Students were randomly assigned to one of three kinds of classrooms—windowless，with a window looking out onto built-up space，or with a window looking out onto green space．Each kind of classroom had a similar size and layout．The students took part in one-on-one experiments in which they did 30 minutes of activities that included a proofreading exercise，a speech and a math exercise．Following the activities, the students were given an attention test which asked them to repeat a series of numbers．
The findings: Students did better on both study activities and the attention test if they were in a classroom with a green view，Sullivan said．
The researchers suggest their findings can help planners and policymakers improve students' well-being and learning．For example, planners can choose sites for new schools that already have trees and other vegetation，or they can plant many trees on the site; architects can design classroom，dining room and hallway windows so they look onto green spaces．
12．What did the study find out about high school students
A．They like to have green plants in their classrooms．
B．They will get better grades when studying in different classrooms．
C．Changes in school design will influence their attitudes towards teachers．
D．A green view through a classroom window can improve their performance．
13．What does the underlined word“significant” in paragraph 2 mean
A．Traditional． B．Important．
C．Necessary． D．Early．
14．What is paragraph 3 mainly about
A．How the study was carried out．
B．Why the study was different．
C．The purpose of the study．
D．The result of the study．
15．What do the researchers think of the study
A．It has drawn public attention to education．
B．It can play a guiding role in school planning．
C．It has encouraged students to get close to nature．
D．It needs more support from high school teachers．

My name is Tom．Before I was born，the doctors examined my mom and found there was something wrong with my face，and actually it was worse．With my “weird” face，I struggled in school，realizing kids were scared to touch me，often avoiding me．Fortunately，I had my friend Jack and teacher Mr． Green supporting me always．However，one thing happened to me which almost destroyed me．
For me，Halloween was the best holiday in the world．I got to dress up in a costume．I got to wear a mask．I got to go around like every other kid with a mask and nobody thought I looked weird．On the morning of Halloween this year，I rushed to my room and started to put on the Spiderman costume I had mentioned to Jack，but all of a sudden，I didn't feel like wearing it．So，at the last minute，I changed into the Ironman costume from last year．Then，my dad sent me to school．
Walking through the halls that morning on my way to the lockers was，I have to say，absolutely awesome．Everything was different now．I was different．Where I usually walked with my head down，trying to avoid being seen，today I walked with my head up，looking around．I was starting to think this was going to go down as one of the most awesome days in the history of my life，but then I got to the classroom．Several classmates were talking and I knew who they were for their voices，even in costumes，those who were popular guys but mean to me at school．Then I noticed another voice，so familiar，from my best friend，Jack．He said，“I've thought about this a lot and I really think．．．if I looked like Tom，seriously，I think that I'd kill myself．”
After hearing his words，I walked out of the classroom without anyone knowing I had been there．My face felt like it was on fire while I walked down the stairs to a quiet place with no one there．I was sweating under my costume．And I started crying．
注意：1．续写词数应为 150左右；

[参考范文]　
Just when I felt utterly defeated，I felt a gentle touch on my shoulder．I turned to see Mr． Green standing there．I took off my mask and just cried for I didn't know how long．All the pretense of toughness crumbled．Only after I stopped crying did Mr． Green，his voice filled with concern，ask，“What's going on，Tom？” I opened up to him about Jack's perception of me and the pain those words inflicted．Mr． Green responded with reassurance，speaking in a gentle tone，“Tom，sometimes people say hurtful things they don't really mean．I'll have a chat with Jack and sort things out．”
Shortly after Mr．Green talked to Jack，I noticed Jack rushing to me with guilt in his eyes．“Tom，I was mean and stupid．I should never have said that stuff in front of the Ironman．I didn't mean the stuff I said，”he admitted regretfully．He went on to explain that he had momentarily wanted to fit in with those popular kids，even though he hadn't truly meant to become like them．In that moment，the internal struggle Jack faced and reasons behind him uttering those hurtful words became clear to me．I accepted his sincere apologies and we hugged each other，with a warm current flowing between us．Halloween，the holiday I cherished so much，took on a new meaning for me that year，symbolizing the strength of friendship and the power of healing．

28．C　[根据上文“because she couldn't dare to ask doubts in class or ask for”可知，女孩的朋友在课堂上不敢提问，也不敢向他人寻求帮助(help)。故选C项。]
29．D　[根据上文“She told me that her friend was severely socially anxious”可知，女孩的朋友社交焦虑程度很严重，不敢在课堂上提问。由此可推知，她会把课堂上遇到的问题写下来(write down)，然后这个女孩再帮她去问。故选D项。]
30．C　[根据下文“With her help”可知，此处指女孩替她的朋友问问题。本空是对上文多次出现的“ask”的同义词复现。故选C项。]

【语篇解读】　本文是一篇说明文。文章追溯了饺子的历史，虽然到底是谁发明了饺子仍然是个谜，但一些学者怀疑，它们最早是在1 700多年前由生活在中国西部和中亚的民族传播到古代世界各地的。
36．who　[考查主语从句。根据空后的“But some scholars suspect... more than 1，700 years ago．”可知，一些学者怀疑它们最早是在1 700多年前由生活在中国西部和中亚的民族传播到古代世界各地的。由此可知，此处指的是到底是谁发明了饺子仍然是个谜，空处引导主语从句，且在从句中作主语，表示“谁”，故填who。]
37．traditional　[考查形容词。根据空处所在的位置可知，空处所填词在句中作定语，修饰meat filling。由此可知，空处应填形容词traditional。]
38．harder　[考查形容词比较级。根据空后的than可知，此处应用形容词比较级，故填harder。]
39．between　[考查介词。根据空前的“The relationship”以及空后的“Chinese dumplings and those in other areas”可知，该空应填between，表示“中国饺子和其他地区的饺子之间的关系很难追溯”。且the relationship between... and...为固定搭配。]
40．have made　[考查动词的时态。此处指食物历史学家已经根据可用的线索做出了最好的猜测；根据语境可知，做出猜测发生在过去，但对现在造成了影响，所以用现在完成时，故填have made。]
41．eventually　[考查副词。句中established为动词，应用副词来修饰，故填eventually。]
42．introducing　[考查非谓语动词。分析句子结构可知，该空在句中作非谓语，且introduce与主语the Mongol Empire构成了逻辑上的主谓关系，故填introducing。]
43．varieties　[考查名词复数。分析句子结构可知，空处在句中作主语；根据空后的were可知，该空应用所给词的复数形式，故填varieties。]
44．to have been used　[考查非谓语动词。“主语＋is＋及物动词的过去分词＋动词不定式”是一个固定句型，相当于It is＋及物动词的过去分词＋that从句；由于The term与use之间是逻辑上的动宾关系，且use这一动作已经完成，故填to have been used。]
45．where　[考查定语从句。分析句子结构可知，空处引导非限制性定语从句，先行词为Japan，关系词在从句中作地点状语，故填关系副词where。]
