In my early childhood, I was often surprised when I saw my father making     1     small number of money with difficulty. He was very tired during the day,     2     he still chose to have a part-time job at night. As a child, I was     3     (ability) to understand him.

I can’t forget he played with me when I was 3-4 years old. He taught me how to read. He took care of me all night when I was sick. Whenever I felt down he would cheer me up. He also cared about my lessons. When I was older, my father thought that I should     4     (send) to Beijing for the best education. Whenever I needed money, he never refused.

Two years ago, I got a job at a hospital in Beijing. When I helped my first patient, I got a strong feeling of satisfaction. When I got my first salary (薪水), I spent it all on myself.

I remembered it was an     5     (forget) morning. When I returned home, I heard my father     6     (communicate) with one neighbor. He was    7     (proud) telling him my success in the job. His dream of giving his son a good life came true finally. I was moved by     8     my father said. At that time, I thought I was selfish, I had never thought of doing something for my father.

Fathers are not very good at expressing their     9     (feel). If you carefully go through your childhood memory, you will notice your fathers are always there when you need them.

If today I can complete each task much     10     (succeed), this is because of my father. So I want to say thank you to my father, then what about you? Do you want to say thank you to your father? Please do it immediately tonight.

    1    (lie) under waters across the globe are an estimated three million shipwrecks, all of     2     indicate human attempts over the centuries to explore Earth's furthest corners. While there is little land on our planet left unexplored, the vast sea bed almost     3    (remain) unknown.

Considering our limited knowledge, it's not surprising that exploration of the oceans constantly brings about discoveries in various     4    (science) fields.

First, many archaeological finds are made in shallow waters, including whole cities     5    (bury) underwater. The ruins offer precious information about the past. However, the challenges of pressure, darkness and intense cold at vast depths make     6     difficult to discover more of the past.

Amazing biological discoveries are also being made, like the barreleye living 6,000 meters below the ocean's surface. Such discoveries enable us     7    (have) a better knowledge of the capacity for life even in extreme circumstances.

Additionally, so far more new natural resources such as fire ice     8    (find) in oceans. Besides, the research conducted by China's underwater vessels helps scientists identify areas for deep-sea drilling and better understand how the sea bed was formed.

Humankind is entering a new age of oceanic discovery. Oceans will be as familiar     9     us as the land where we live through all-round international     10    (cooperate).
