Early excitement about the next generation of the iPhone is building months ahead of an expected autumn debut(问世). Analysts expect Apple to release three iPhones this year, but the one getting the most attention is a rumored super-premium model to celebrate the iPhone's tenth anniversary. And, for that phone, Apple is expected to change the type of screen the iPhone uses.
Here's a quick look at what you need to know about what it means if Apple switches from its current liquid crystal display (LCD) screens to a type of organic light-emitting diode (OLED) screen called AMOLED.
The essential difference between an LCD screen and an AMOLED one is the presence of a backlight. Thanks to that difference, AMOLED screens can be very thin, which means you can make thinner products. They also provide more vivid colors, which is a reason that television makers have been pushing OLED in its various forms for their big screens. AMOLED screens, in particular, boast(夸口) even greater control over each individual pixel （像素）— which means better contrast for the viewer. These screens can also improve battery life. Because there's no backlight, AMOLED screens can be more energy-efficient when the user is viewing darker subjects, allowing the phone to shut off pixels and stop drawing power.
So why hasn't Apple switched to AMOLED yet? After all, Apple competitors such as Samsung and LG already have these screens on their smartphones.
AMOLED screens are not cheap to produce. It's also not that easy to make the complex AMOLED screens, which could explain why most Apple fans expect that only the highest-end phone will have the new screen.
And then there's the cost. The switch to AMOLED has also been cited as a reason that the price of the high-end iPhone may jump above the $1,000 mark. Beauty, even in a mass-produced world, does not come cheap.
Still, the expense may be worth it, especially as people shoot more photos and videos.

NEW DELHI—In India’s space center on the barrier island of Sriharikota, the white-jacketed scientists held their breaths.
The country’s trusty red-and-white satellite launch vehicle had lifted off moments before and blasted into orbit.
The Polar Satellite Launch Vehicle C-37 was about to perform a delicate maneuver(操纵，任务)—carefully sending 104 satellites into the heavens, the highest number ever attempted in one mission. One Indian space analyst on television likened the complicated maneuver to dropping children at different bus stops.
About 10 a.m. Wednesday, the announcement came: All the satellites had been successfully launched. The scientists breathed a collective sigh of relief, and backslapping and applause followed.
“This is a great moment for each and every one of us. Today we have made history,” project manager B. Jayakumar said afterward. The total number of satellites far outstripped(超过) the previous record—37 at the same time sent into space by Russia in 2014.
Wednesday’s launch was another success for the Indian Space Research Organization (ISRO), which is rapidly gaining a reputation globally for its effective yet low-cost missions.
India had already sent up dozens of satellites, including 20 in one launch last year.
In 2014, India became the first Asian nation to send a probe(探测器) into orbit around Mars, a $74 million effort that, as Prime Minister Narendra Modi noted at the time, cost less than what it took to make the Hollywood space movie “Gravity”.
The fierce national pride that resulted after that success sent the Mars probe rocketing onto the face of the country’s new 2,000 rupee($30) currency note (钞票) in November.
“Now India is showing its competitiveness in the $300 billion global space market,” said Rajeswari Pillai Rajagopalan, head of the Nuclear and Space Policy Initiative at the Observer Rearch Foundation in New Delhi.
1.What does the underlined word “likened” mean in the 3rd paragraph?
A. contributed
B. compared
C. preferred
D. tied
2.What does India’s Prime Minister Modi imply according to the 8th paragraph?
A. The 104-satellite maneuver cost less money than the film “Gravity” did.
B. Shooting a film is always more expensive than launching a rocket.
C. The Mars probe rocketing is characteristic of being low in cost.
D. All real explorations are cheaper than virtual ones.
3.The way India adopted to show the significance of the Mars probe rocketing is equal to the way Chinese government use ________ in China.
A. Chairman Mao Zedong’s portrait
B. a picture of the Long-march rocket
C. a picture of the Three-gorges(峡谷) project
D. President Xi Jinping’s portrait
4.It can be inferred that after the success in the 104-satellite launch, India will ________.
A. become No. 1 in the global space market
B. take up a larger market share in the future
C. show its ability among local competitors
D. have an order of $300 billion
After the Earthquake had stopped, when the rescuers reached the ruins of a young woman’s house, they saw her dead body through the cracks. But her pose was somehow strange that she knelt on her knees like a person was worshipping(礼拜); her body was learning forward, and her two hands were supported by an object. The collapsed house had crashed her back and her head.
With so many difficulties, the leader of the rescue team put his hand through a narrow gap on the wall to reach the woman’s body. He was hoping that this woman could be still alive. However, the cold and stiff body told him that she had passed away for sure.
He and the rest of the team left this house and were going to search the next collapsed building. For some reasons, the team leader was driven by a compelling force to go back to the ruined house of the dead woman. Again, he knelt down and used his hand through the narrow cracks to search the little space under the dead body. Suddenly, he screamed with excitement, “A child! There is a child!”
The whole team worked together; carefully they removed the piles of ruined objects around the dead woman. There was a 3-month-old little boy wrapped in a flowery blanket under his mother’s dead body. Obviously, the woman had made a sacrifice for saving her son. When her house was falling, she used her body to make a cover to protect her son. The little boy was still sleeping peacefully when the team leader picked him up.
The medical doctor came quickly to examine the little boy. After he opened the blanket, he saw a cell phone. There was a text message on the screen. It said, “If you can survive, you must remember that I love you.” This cell phone was passed around from one hand to another. Everybody that read the message wept. “If you can survive, you must remember that I love you.” Such is the mother’s love for her child!
