In order to be able to have a smooth conversation with Dr. Rida in English, Zhao Anran made several assumptions in his mind, imagining what the other party would say and how he should answer, and then wrote down the professional terms and phonetic transcription that might be used, and took photos with his mobile phone to save them in case of emergency.

Zhao Anran, who had done enough inner drama, mustered up the courage to walk to Dr. Rida's desk and began the conversation she had been preparing for a long time.

“Excuse me for interrupting， please allow me to introduce myself. I am a Ph.D. student this year. I'm very interested in your research. Would you please show me your solar greenhouse if you have time?” (Sorry to excuse me, but allow me to introduce me, I'm a PhD student this year.) I'm interested in your research direction, can you take me to see your solar greenhouse? Zhao Anran finally made the meaning clear in stumbling and slightly stammering English.

“Sure， of course. Follow me.” (Of course, come with me.) Dr. Rida is clearly pleased that there is interest in his research, and he is happy to present the results so far. She got up and took Zhao Anran to the greenhouse on the experimental platform.

This is a greenhouse of more than 20 square meters, with a herringbone on the top of the greenhouse, the whole greenhouse is covered with plastic film, and several solar modules are installed on one side of the roof of the greenhouse, which is the same as the teaching building of the college.

“This is my experimental greenhouse. The semitransparent photovoltaic modules were installed on the roof of the greenhouse to generate electricity.” (This is my test greenhouse, where translucent photovoltaic modules installed on the roof of the greenhouse are used to generate electricity.) Dr. Rida introduces his research greenhouse.

Zhao Anran quickly searched for the corresponding meaning of those professional terms in his mind, "photovoltaic modules" is a photovoltaic module, but what does "semitransparent" mean? Zhao Anran, who had been immersed in thinking about the meaning of the words, did not respond to Dr. Rida in time.

“Hello? Are you OK?” (Are you okay?) Dr. Rida asked with concern.

Zhao Anran had no choice but to honestly admit the fact that he was not good at speaking, "Sorry, actually, I'm not good at oral English." (Sorry, I'm not good at spoken English.) ）

Rida smiled, slowed down and said, "Well, I'll explain it to you patiently until you understand." (Well, I'll patiently explain it to you until you get it.) ）

“Thank you very much!” (Thank you very much!) Zhao Anran was very happy, studying with Dr. Rida can not only learn professional knowledge, but also practice spoken English, which is really a double thing!

For several days in a row, as long as Zhao Anran saw Dr. Lida go to the greenhouse to do experiments, she followed closely. Dr. Rida planted cucumbers and tomatoes in pots in the greenhouse, and when they needed to be watered and fertilized, she helped to water and fertilize them together. Prior to this, she had never been involved in agriculture. She has always studied engineering, and she can easily learn about machinery, but the study of the combination of agriculture and energy is definitely the first time for her. While helping Dr. Rida take care of the crops, she also asked for knowledge about agriculture and solar energy, and sometimes she couldn't understand Dr. Rida's vocabulary, so she simply took out her mobile phone to look it up, and she was not afraid to let Dr. Rida know that her spoken English was a rookie.

In the office at night, Zhao Anran downloaded a lot of research articles related to solar greenhouses, stumbled on relevant literature from scratch, and classified the articles according to the content of the research. which articles regulate the greenhouse microenvironment; which articles analyze the greenhouse energy balance; which articles are studied in conjunction with crops; Which articles are ...... using computer simulations.

Professor Li gave Zhao Anran two weeks to understand and choose her own research direction, so far, it seems that she has made a choice, she must explain the reasons for choosing the solar greenhouse, and also sort out the research background of the solar greenhouse, she hopes to give Professor Li a good impression, she is indeed a hard-working student.
