We all love to take photographs. It’s a simple way to record a special moment or an amazing view. In fact, they show a snapshot in time. This hasn’t really changed since the invention of photography in the 1830s. 【小题1】

For many years, we have used traditional cameras to take our pictures with. And we’ve had a range of cameras to choose from. But a great change has come with the development of digital (数码的) technology. 【小题2】 It’s enabled us to take a snap and review our pictures immediately. We’ve been able to deal with them in post-production, using software on our computer. And of course, we’ve been able to share them like never before - especially on social media.

Now we have the smartphone. 【小题3】 So does that mean the traditional camera will eventually be taken over? A research from Japan shows the market share is becoming smaller: shipments of digital cameras from companies like Olympus, Canon and Nikon were down 39% year on year.

【小题4】 He points out that while people are swapping their digital cameras for smartphones, camera makers are looking at the more high-end market, the DSLRs and mirrorless cameras.

Certainly, the growth of the smartphone means more and more of us are taking photos and it opens our eyes to the creative possibilities it can provide. 【小题5】 But whatever camera viewfinder (取景器) we end up looking through, it’s important to remember the basics of focusing, good lighting and framing, and getting your subject to say ‘cheese!’

The Center for Humane Technology is made up of people who created many popular apps for big tech companies like Google, Facebook and Twitter. 【小题1】

The center has started a movement called the Truth About Tech. Its aim is to teach students, parents and teachers about the dangers of spending too much time on smart phones and computers.

According to studies on kids, more than 95 percent of primary school children spend time every day using a computer, or smart phone. About 78 percent of teenagers check their phones every hour. 【小题2】 They are afraid that they may miss an important call or message during the night.

【小题3】 Spending too much time online can cause people to put on weight and also influence how they feel. Many people become worried or nervous because they feel they aren't having as much fun as their friends are. 【小题4】 They may also find it harder to make friends in real life.

【小题5】 They say that when big tech companies are designing tech tools for kids, they should think about what they would want for their own children.

Canada’s new Dark Vessel Detection program is using advanced satellite technology to find illegal fishing ships that attempt to steal fish from waters around the world. Illegal fishing is a major contributor to the decrease of fish and their habitat destruction.

It is said that illegal fishing accounts for about 30 percent of fishing activity worldwide. It means that u to 26 million tons of fish are caught at a cost to the global economy of more than $ 23 billion a year. Illegal fishing occurs both on the high seas and within the 200 mile limits of coastal states. It has an especially negative effect on coastal populations in undeveloped areas.

Now, the government’s Fisheries and Oceans Canada, in partnership with the Department of National Defense and MDA (Canada’s space technology maker), has started a new program that has already led to fines on five foreign ships. The $7 million Dark Vessel Detection program uses satellite technology to locate and track ships. Some illegal fishing ships have switched off their location transmitting (传输) equipment, in an attempt to avoid surveillance (监视) and control.

The program offers state-of- the-art satellite data to small island nations and coastal states around the world. The local economies of those places are often influenced by illegal fishing. Finding illegal fishing ships from space will allow these small island nations to focus on their investigations and protect their fish.

“Illegal fishing threatens the health of our fish population and takes resources (资源) away from hard- working, legal fishermen,” said Bernadette Jordan, the Minister of Fisheries, Oceans and the Canadian Coast Guard, “This state -of the art system will help Ecuador and small island nations in the Pacific region deal with illegal fishing. Such illegal activity will do great harm to the Galapagos Islands and the food and economic security of its people,” she added.
