As a senior high student with     1     (curious), I found myself stepping onto the campus with     2     sense of anticipation. The facilities and the rich tradition of the university made a lasting     3     (impressive) on me. In that moment, I felt like an author who is ready     4     (explore) the vast collection of knowledge that lay before me. What’s more, I thought that     5     (organize) my thoughts and ideas was very much like the precise workings of an engine. Just as an insect     6     (careful) constructs its nest, I aimed to construct a solid foundation of education during my time here.     7     each new course and academic efforts, I added to my     8     (collect) of experiences, expanding my understanding of the world. This campus became a place of growth and self-discovery,     9     I learned to adapt and thrive in different environments.

Susana Vazquez-Torres is a fourth-year graduate student at the University of Washington who wants to someday invent new drugs     1     neglected diseases.

Lately, she     2     (think) a lot about snake bites: Around a hundred thousand people die each year from snake bites, according to the World Health Organization—and yet, she says, “the current therapeutics are not safe and are very expensive.”

Part of the problem is     3     developing new drugs for things like snake bites has been a slow and laborious process. In the past, it might have taken years to come up with a promising compound.

Technology has become an integral part of our lives, and its impact on education cannot     1     (ignore). While some people may be skeptical about the role of technology in education, there is no denying that it has brought about several positive changes.

One of the most significant advantages of technology in education is the ability     2     (personalize) learning. With the help of technology, educators can tailor their teaching methods to the needs and learning styles of individual students. For example, online learning platforms can provide students with personalized learning paths based on their progress and     3     (perform).

Cholera used to be one of the most     1     (fear) diseases in the world, until a British doctor, John Snow, showed     2     it could be overcome. This illness causes severe diarrhoea, dehydration, and even death. In     3     early 19th century, when an outbreak of cholera hit Europe, millions of people died from the disease.

Tuyouyou was chosen as a researcher of a team of scientists     4     the purpose of discovering a new treatment for malaria.

Cold temperatures, biting wind, heavy snow and slippery roads are the common challenges that trouble or even interrupt winter commutes (通勤). However, for students and teachers at a college in Northeast China,     1     have been severely affected by the recent cold wave and snowstorm, their commute has been made easy, warm and safe thanks to the newly     2     (build) skywalks on campus.

In clear contrast to other colleges in Northeast China, students at Harbin Institute of Technology have experienced an     3     (entire) different scene. They comfortably move between classrooms, libraries, cafeterias, dormitories, and the gym in short sleeves (袖子) through the skywalks, all within     4     five-minute walk. Some students have even been spotted     5     (enjoy) ice cream while admiring the snowy scenery along the pathways. Praise and     6     (admire) have poured in for the usefulness of the sky bridges and the thoughtfulness of the college.

The university     7     (launch) the construction of the sky bridges on campus in 2022, aiming to effectively alleviate the impact of extreme weather on campus life     8     increase convenience for both teachers and students. With a total length of 1,330.13 meters, the sky bridges are built in three stages. On Nov 7, the second stage of the walkway system was fully operational and open     9     trial use. Currently, 881.81 meters of skywalks are     10     (access).

This is the year 2070. Today is my    1     (fifty) birthday, but I look like a person of eighty- five. I have serious kidney (肾脏) problems because I don’t have enough water     2     (drink). I’m afraid I don’t have much time left to live. I’m already one of the oldest people in this society.

I remember when I     3     (be) five years old, everything was very different. There were lots of trees in the parks. I could enjoy a shower for half     4     hour. At that time,     5    (woman) all had beautiful hair. Now, we have to shave (剃光) our heads to keep them clean without the use of water.

I remember there were “Saving Water” warnings in many public places, but nobody     6     (pay) attention. We believed water would last forever. Now, all the rivers and lakes are either dry or polluted. Water is much     7     (expensive) than gold and diamonds.

In the past, doctors suggested adults drink eight glasses of water a day. Nowadays, I am allowed half a glass only. Most people are weak and sick.

When my son asks me about my childhood, I tell him about how pleasant it was to fish in the rivers     8     how healthy people were. When he asks, “Why is there no clean water now?” I feel guilty (有罪的). I belong     9     those people who simply turned a blind eye to all the warnings.

I hope the people living in the 2020s     10     (true) understand the importance of saving water.

Regarded     1     “the goddess scientists”, Yan Ning is an admirable biology researcher at Princeton University. She is a rising star in the science world and her resume is     2     (impress). After graduating from Tsinghua University and Princeton, she     3     (invite) to set up her own laboratory at Tsinghua in 2007. At age 30, she became one of China’s     4     (young) female professors.

It was a long road to get     5     she is now. Yan works at least 14 hours a day, but she’s energetic, because research is the most “comfortable” job for her. This     6     (devote) to her work probably helped Yan in her research to identify the structures of proteins in cells’ plasma membranes, which puzzled scientists for half a century.

Apart from     7     (perform) scientific research, Yan enjoys TV dramas and classic novels.     8     (surprise), the novel Journey to the West inspired her to become a structural biologist. As she realizes her own dreams, Yan tries to encourage more women     9     (join) in science. In her eyes, there is no difference between men     10     women in the scientific fields. “Women can work as excellently as men and live the way they choose to,” she said in a public interview.

Speaking of medicine, through new technology, people who have brain     1     other injuries will be able to find new hope. There     2     (be) recently, for example, technology which can help blind people to see using cameras and deaf people to hear using microphones that     3     (connect) to their brains. Future technology will assist people in overcoming all sorts of physical disabilities.

My pen pal, whose name is Mike,     1    (come) to our school to study next month. He comes from America and is eighteen. He is a tall and thin person with yellow hair and blue eyes,     2     makes him look different     3     us.

There are four people in his family. His father is an engineer, his mother is a teacher and his     4    (young) sister is a high school student now.

He has     7     variety of interests,     8    (include) listening to pop music and playing basketball. He often goes to gym     9    (regular). The reason why he will come to China is that he wants to learn Chinese and taste Chinese food. I’m looking forward to his coming and hoping you can make friends with     10    (he).

WeChat, one of the world’s most popular mobile apps and social networks, brought home iF Gold Award for its smart retail innovation, Scan & Go. It is     1     first ever Chinese product to win gold in the iF Service Design category.
