Photographic self-portraits have existed for as long as cameras have been in human hands. But what about selfies in space? On Twitter last year, NASA astronaut Edwin Aldrin, who famously became the second man to walk on the moon in July 1969, laid claim to a spaceflight first: taking the first selfie in space during the Gemini XII mission in 1966.
“For me, it needs to be digital to be selfie,” argues Jennifer Levasseur, a director at the Smithsonian National Air and Space Museum. According to Levasseur, the concept of a selfie is directly linked to internet culture. “The thing that makes a selfie is sharing it,” she says.
Still, astronauts have been carrying cameras aboard space vehicles since the 1960s. In 1966, Aldrin used a Hasselblad camera designed specifically for space. Hasselblad also painted the first camera in space a matte(磨砂) black to reduce reflections in the orbiter window. But cameras used in space need to survive extreme conditions, like temperature swings from -149° to 248°F, so Hasselblad painted later model silver.
Astronauts visiting the moon then had to take out the film and leave their camera bodies behind when they returned to Earth, because early space missions were limited by a weight limit on the returned trip. Then a big change in space camera technology came after the space shuttle Columbia broke apart on its return to Earth in 2003, Levasseur notes. “Fear that they’d never be able to bring film back from space and lose all that hard work accelerated the push for digital,” she says.
Today, astronauts also have access to internet and social platforms in space and can post true space selfies made using digital cameras. Similarly, space robots are participating in selfie culture, capturing remote pictures of themselves in space or on other planets and sending them back to Earth.

The age of technology is a great and convenient thing, but it does have effects on us in many different ways.
It causes long-term memory loss. Thanks to Baidu, we don't really have to remember much of anything. Questions are answered at the drop of a hat because Baidu is all-knowing! Is that a good thing, though? People aren't digging through their brains anymore to find answers. Here's the good news: we can still exercise our long-term memory by simply thinking before we Baidu. If we don't want to go down that road, we can search Baidu for some memory games to play. Turn Baidu into an asset instead of an enemy.
It makes us lack patience. Baidu gives us what we want. Everything is instant. In fact, if we have to wait for even a handful of minutes for anything, we start losing our minds. This idea of instant satisfaction carries through to many other aspects of our lives, too, like when we go out to eat, drive in traffic, or even deal with workplace accidents. Instead of using Baidu to lessen our anger, try searching for some mindful meditations (沉思).Focus on our breath and realize everything doesn't have to move at lightening speed. We can actually listen to some peaceful spa or meditation music on our Pandora, too!
It wastes our time. Be honest, how much time are we spending on Baidu every day? Whether we're doing research for our own personal needs, buying clothing, or writing a research paper, we all spend a ton of time on the trusty Internet. Are we always being efficient with this time? For the sake of our precious time, if we haven't used Baidu Drive, we should. Keep spreadsheets, text docs, PDFs, slideshows, and even recordings exactly where we can easily find them. Keep a running list of websites we know we'll revisit.
Overall, things are different these days. Yes, there are noticeable negative side effects because of the Baidu invasion, but we don't have to fall into that trap. Stay sharp and don't let ourselves become imprisoned doing the Baidu god's bidding.
1.Which of the following can best replace the underlined part “at the drop of a hat”?
A.at one point B.in no time C.in a way D.at a loss

B.We can't get everything with Baidu.

3.What is the author's advice on saving time online?
A.Using Baidu Drive.
B.Keeping papers correctly.
C.Being efficient with work.
D.Emptying websites records timely.
4.What does the text mainly tell us?

C.The technology and influence of the Internet.
D.The disadvantages and risks of the Internet.
Cala didn’t like us. Any of us. We didn’t do anything to offend her and she didn’t know us but that didn’t matter; she still didn’t like us.
As new teachers in the Emirati school, we Westerners greeted her every day. She ignored us. She came into our rooms and bypassed us as she shook hands with all the non-Westerners. Whenever we saw her, she avoided eye contact with us. Eventually, we stopped trying to befriend her.
I wouldn’t say her nationality but her friends had been fired from the school. We had been employed in their places and that was enough for her to have nothing to do with us.
Well after 16 months in the school we had a secret friend gifting. To my surprise, I drew her name from the glass jar and that meant she was my secret friend. My role was to buy her a gift and say something about her when we publicly acknowledged who our secret friend was.
I decided to gift her a coloured bangle(手镯). I added a postcard and wrote “Love and Blessings, Rose Marie.
Then came the day. We all gathered in the meeting room. When you gave your gift, you said a few kind words about your secret friend and passed the gift to her. What could I say? Everyone knew she didn’t like the Westerners. She taught music in the school so I said “My secret friend is someone who brings music to our ears every day.” She came forward with a huge warm smile. She hugged me and kissed me on both cheeks and accepted my gift.
Since then, she smiles often. We hug and shake hands when we meet. I have seen her wear my gift several times and I am so pleased.

On account of the government shutdown, many of the city’s best attractions, such as the national museums, are closed. It may affect your social plans. That’s especially true if you have out-of-town visitors coming to the District. Don’t worry! For every closed museum, we’ve offered up a suitable substitute that is privately run, thus not subject to the shutdown. Here’s where you can go instead.
Anacostia Community Museum and the National Museum of African American History and Culture
Alternatives: Banneker-Douglass Museum or Alexandria Black History Museum
The National Museum of African American History and Culture is one of the hottest draws on the National Mall, with free tickets taken weeks in advance. Its sister museum, the Anacostia Community (社区) Museum, takes a community-focused look at African American history. So does the Banneker- Douglass Museum in Annapolis, which traces (追溯) the African American experience in Maryland, and the Alexandria Black History Museum, where exhibitions honor local activists and explore the influence of slavery in the area. And unlike the African American Museum, neither requires you to plan ahead.
Hirschhorn Museum and Sculpture Garden
Alternative: Glenstone
Wandering through the galleries at Glenstone, you’ll come across some of the biggest names in 20th century art — Jackson Pollock, Jean-Michel Basquiat and Robert Rauschenberg. Glenstone sits on a 230-acre estate (土地) that doubles as an outdoor sculpture garden. Free tickets for Glenstone are often reserved weeks in advance, but 72 free tickets are available every day for anyone who takes a Montgomery County Ride-On Bus from Rockville Metro Station to the museum.
National Museum of African Art
Alternative: The African Art Museum of Maryland
Masks, musical instruments and jewelry can be found in Fulton, where the African Art Museum of Maryland houses a collection of traditional and contemporary African artworks and objects. And the best part, for visitors on a budget? Admission is free.
1.Where can visitors go to explore the history of African Americans during the shutdown?
A.National Museum of African Art.

How have you been? I miss everyone. Fortunate, my new classmates are friendly to me. Because it's farther south, all plants here are difference. It doesn't even snow in winter. I suppose I won't need that blue coat any longer. Last night, I asked your mom if you could visit me and stayed for this whole weekend. I said she could show you around this place and we could go swimming in the lake. Your mom said it was fine, what was surprising. She thought it would be wonderful experience for you. I was such excited that I forgot to express my thank to her. Remember to bring your swim suit purchasing in the supermarket before you have come.
