When I was in middle school, I enjoyed reading science books, and they were really difficult to understand them. Whenever a problem beats me, I would turn to my physics teacher for help. Go through materials together page by page, we were tearing the mask of nature off. It was his guidance which encouraged me to study physics serious today. Now we’re in a period when science plays an important role on people’s lives. From construction workers who build laboratories to teachers who pass on knowledges, everyone contributes to science in their own unique ways. All in all, science is everlasting topic for mankind. Faced with it, we must make ourselves well preparing.

Three simple keys to success

Being successful means different things to different people. 1. My point is, the specifics involved in finding success can vary greatly, depending on your goal.

There are three basic components necessary for finding success, regardless of the specifics of your pursuit. And, since the desire for ownership is the driving force behind acquisition, I’ll use the word OWN as my simple three-item method for success.

1.O-Opportunity: one of the most important components in finding success is being able to identify opportunity. It is to success what wind is to sailing. 2. Identifying opportunity is the first step; awareness sets your sails for success while your motivation provides the wind.

2.W-Wisdom: By definition, wisdom is the accurate application of knowledge. 3. It requires clear understanding, great insight and good judgment. Once opportunity is identified, you must use all your inner resources to seize it and make the most of it. 4. Finding success when opportunity presents itself often means reaching out for help in areas where you have weakness.

3.N-Never give up: This might possibly be the most important for success. The key is to first break your goal down into workable parts so you don’t feel pressured, and then to work each part at ease with both enthusiasm and purpose. It takes a lot of time, effort and determination to succeed. 5.

A.Being successful demands doing well.

B.But wisdom involves more than just knowing.

C.You simply can’t have one without the other.

D.Having this attitude keeps you moving in face of trouble and becomes the driving force.

E.Besides, wisdom means knowing your limitations.

F.You’ll finally succeed if you follow these steps.

G.The road to success is being largely determined by what result you want to achieve.

    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.

1.Why do selfies in space need to be digital according to Jennifer Levasseur?

A.Astronauts are fond of studying technology.

B.Astronauts are eager to be famous on the Internet.

C.Astronauts desire to communicate on social platforms.

D.Astronauts want to overcome the fear in space.

2.Why can the Hasselblad camera adjust to the temperature changes in space?

A.It is painted silver.

B.Its matte black gathers light.

C.Its design is special.

D.It can reduce reflection itself.

3.What contributed to the faster development of camera technology in space?

A.The heavy space tasks.

B.A returned space shuttle.

C.A spaceflight crash.

D.The improved film.

4.What can be a suitable title for the text?

A.The Origin of Selfies in Space

B.The Brief History of Selfies in Space

C.The Significance of Selfies in Space

D.The Popularity of Selfies in Space
