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.

1.According to the passage, when will the iPhone’s tenth anniversary most probably be held?

A. In June.

B. In March.

C. In November.

D. In January.

2.According to most Apple fans, AMOLED screens will only be used on ________ this year.

A. the cheapest iPhones

B. the most massive iPhones

C. the highest iPhones

D. the most expensive iPhones

3.What does the underlined sentence indicate?

A. It is very expensive to become beautiful.

B. Everything has a price.

C. The more you pay, the more beautiful you will become.

D. Practice more, and you will become better.

4.What’s the author’s attitude towards the expected iPhone?

A. Negative.

B. Critical.

C. Positive.

D. Uninterested.

My husband and I are saving thousands of dollars every year by growing our own vegetables in our backyard. We learn something new every year and this website has been made to share tips with other people that would like to grow some of their own food.

It’s true that if you are starting from fresh, it will cost a little bit of money to get started. However, once everything is set up, the cost is very small and the rewards are huge. The size of your family and how many vegetables you eat determine exactly how much money you can save every year. We do a lot of juicing, so we are saving thousands of dollars by growing some carefully selected greens.

There is an amazing sense of accomplishment when you grow your own vegetables. Vegetables out of your vegetable garden don’t get any fresher, tastier or more satisfying. The whole family can get involved in this hobby and kids will learn where food comes from and appreciate nature even more.

Our approach to vegetable gardening is completely different from the normal one. We are doing it in the lazy way with zero digging and fertilizing(施肥). The way we grow our vegetables is to emulate natural ecosystems. No rows of carrots can be found in our garden beds. Rain forests seem to do just fine without human interference(干预) or having plants sown in rows, so we have applied the same principle to our vegetable garden and we care producing more vegetables than ever.

By copying nature we spend little time working in the vegetable garden but get a much better crop than previous years when we followed the rules. What can I say? We’re such rebels.(叛逆者)

1.What does the author think about people growing their own vegetables?

A. It is a rewarding activity. B. It is costly in the beginning.

C. People should devote many efforts. D. People should share their tips.
