1 . Four Places Named After Scientists in Antarctica
There are many scientific breakthroughs made by women in Antarctic. Here are four landmarks in Antarctica and the female pioneers they’re named for.
Jones Terrace (梯田)
The ice-free terrace in eastern Antarctica’s Victoria Land bears Jones’ name. In 1969, geochemist Lois M. Jones led the first all-female research team from the U.S. to work in Antarctica. Jones and her team studied chemical weathering in the McMurdo Dry Valleys, an ice-free area of Antarctica. Through chemical analyses of rocks they had collected, Jones and her team discovered many geochemical characteristics of the valley’s ice-covered lakes.
Mount Fiennes
8,202-foot-high Mount Fiennes, located on Antarctica’s largest island — Alexander Island — is named for Ginny Fiennes. She established and maintained 80-foot-tall radio towers in the Antarctic. In 1985, Fiennes became the first female who was invited to join the Antarctic Club, a British supper club open to individuals who have spent extended time in the Antarctic region.
Francis Peak
The 3,727-foot-tall peak on Antarctica’s Adelaide Island is named after Dame Jane Francis, who is the first female director of the British Antarctic Survey, the national polar research institute of the UK. Her collection of fossils on Seymour Island helped conclude in a 2021 paper that Antarctica’s abundant plant fossils indicate the continent once had a much warmer climate than it currently does.
Peden Cliffs
Peden Cliffs near Antarctica’s Marie Byrd Land are proof of the labor of Irene Peden. She was the first American female scientist to both live and work in the Antarctic, where she used radio waves to study ice sheets. Peden and her team determined how very low frequency radio waves spread over long polar distances by measuring pathways in the ice. They also used varying radio wave frequencies to measure the thickness of Antarctica’s ice sheets.

B.She discovered a lot of ice-covered lakes in the Antarctic. |
C.She was the first female American to explore the Antarctic. |
D.She correctly measured the spreading speed of radio waves. |
2 . When you think of the icy Arctic Ocean, do you picture cold blue waters, on which float (漂浮) icebergs home to animals and fish not seen elsewhere on the planet? Think again, or rather add 300 billion pieces of plastic (塑料) to your picture. That's the amount of plastic that scientists believe is floating around the Arctic Ocean. Most of the plastic is in the area to the east of Greenland and north of Scandinavia.
Where did it come from? After all, the lands near the Arctic are not really full of people. It turns out that ocean currents are carrying plastic thrown into the ocean all the way to the Arctic. An ocean current is an unending movement of sea water from one point to another. It is caused by several things including heat from the Sun, wind and movement of the Earth.
Many of these plastic pieces seem to have travelled for years before reaching the Arctic. This was worked out by scientists studying the plastic problem after they observed the condition of the pieces. While much plastic floats on top of the water, a lot also may be on the sea floor.
Plastic has been widely used for 60 years on Earth and our careless throwing of plastic things is slowly turning the once perfectly clean Arctic into a dangerous place. Unlike food waste and plant waste, plastic doesn't break down so easily. In fact the United States Environment Protection Organization reports that “every bit of plastic ever made still exists”.
What's the effect? Seabirds, sea turtles and other ocean creatures could get hurt and die when they accidentally swallow plastic. Plastic waste affects fishing, affecting people who earn money through fishing. Plastics can let out dangerous poisons (毒物) into the water. These may be swallowed by fish, and when these fish are caught and eaten by people or bigger animals, they could get poisoned too!

3 . The District of Columbia is a destination filled with sites of historic and current importance. During a visit, you can learn about the structure of our government and see monuments, museums and much more.
After exploring some of Washington DC's amazing monuments, the next stop should be to plan out a visit to some of the Smithsonian Institution's complex of museums. With over 19 museums and the National Zoological Park, it’s unlikely that you will have the time to explore each of these museums on a single visit. The best way to enjoy the Smithsonian Institution is to plan out which museums you are most interested in visiting. If you are interested in culture, the National Museum of African American History and Culture is a wonderful choice, where you can learn about the richness and diversity of the African American experience.
Washington DC doesn't just have monuments and museums. There are also chances to enjoy the great outdoors.
The arts and entertainment in Washington DC are also an important part of any trip to the city.
A.Washington DC is filled with important monuments. |
B.You will find art galleries, clubs and fantastic restaurants. |
C.The city has many parks and places to walk and enjoy. |
D.These important landmarks are open all day and into the evening. |
E.The District of Columbia is one of the great destinations you can visit. |
F.You can see the Washington Monument, the Lincoln Memorial and many more. G. Another museum that you should visit is the National Museum of the American Indian. |
What can make a museum attractive? By “attractive” I mean being able to do a lot of things. One of the most
Finally, one of my favorite places is the Musical Instruments Museum in Brussels. Visitors
