It happened one spring morning. I woke up and went downstairs. My mum asked me if I wanted some orange juice.
“Yes, thanks,” I replied, but my voice had changed! It sounded very deep. I was quite1 and so was the dog! But my mum just smiled and said, “Oh, that's just your voice breaking.”
Breaking? That did not sound good! So at school that day, I asked my biology teacher what was happening.
“Don't worry. It's2 common!” she said. “Sound is made by the mouth as the air is 3 out through the voice box, which is in the neck. As you grow older, the voice box grows larger and thicker. When you are a teenager, there can be a 4.
“But my sister is older than me, and her voice is still the same,” I said, a little 5.
“The change is bigger in boys, so you notice it more. Girls' voices only change a little, so it is hard to tell the6.
Now I like my new voice. But the dog still is not sure!
Cruises are becoming more and more popular, with around 20 million passengers per year now enjoying holidays on board luxury ( 奢侈的 ) ships. More people see a cruise as the perfect way to sit back and do nothing, and enjoy time off work. But what is the effect on the environment of this trend?
Although it usually takes less energy for a vehicle to move through water than over land, cruise ships are often massive, with the biggest ones carrying up to 6,000 passengers. Moving such large vehicles requires huge engines which bum as much as 300,000 litres of fuel a day. One scientist has calculated that cruise ships create as much pollution as 5 million cars going over the same distance. Because they are out at sea, they also burn dirtier fuel that isn't allowed on land. Unfortunately, no government has control over the amount of air pollution out at sea. Cruises also produce huge amounts of rubbish, and cruise ships aren't usually good at recycling. Waste water from showers and toilets is usually poured directly into the sea - as much per day as from a small town. Waste food from restaurants isn't put into the sea, but still causes problems when brought back to the land.
Cruise ships also cause difficulties in the cities where they stop. Popular destinations can get five or six ships per day, with thousands of tourists at a time. Good for restaurants? No. Restaurant owners complain that the visitors look around for a few hours and then return to their ship to eat. What's more, the crowds can put off other tourists, who complain that the streets are too busy.
Some towns have banned (禁止) cruise ships or put a limit on the number that can stop at the same time. People who care about the environment worry that as the cruise industry continues to grow, so will the issues for our planet.

First up is the Briefskate. It's made of wood, so it looks like a normal skateboard, but you can open the top. Inside there's s for books and a mobile or an iPad. In my opinion, it's useful and fun, but Tina and I can't skate, so we can't test it...

It's powerful enough to fa large room with music，so you can have a party wherever you are! And the battery lasts for fifteen hours.

It knows where you are and it can follow you to take some awesome photos. It then comes back down, you catch it and put it back on your arm. Simple! The Nixie isn't a to buy yet, but you can put your name on the list to get one as soon as they're on sale.
How to be a safe and smart SEARCHER
Several keywords will help to find better results. Use more than one keyword when you are doing a search. If you want to find out about seagulls, for example, search for bird seagull and not just 'seagull' – because seagull might also be the name of just about anything else, from a hotel to a documentary film.
Exact references can help you find what you're looking for. If you are looking for an exact phrase or sentence, e.g. seagulls are very clever, type it between quotation marks (“”) and only exact matches will be shown. This is useful when you want to find something you've already seen but lost.
Avoid common words like 'a' or 'the' in a search. These aren't always helpful and are usually unnecessary.
Remove unwanted results by adding a minus symbol (-). For example, seagull-hotel-film would leave out all references to hotels and films.
⑷ . Make sure that you spell every word in the search box correctly. The smallest typing mistakes can bring unwanted results - especially when the mistyped word exists.
Have a filter（过滤程序）. It's a good idea to filter your searches, especially when you are searching for pictures. Ask an adult to help you add a filtering system. There are lots of filtering software options available.
Experiment with different search engines until you find the one that's best for you. Some search engines personalise the results. So check out the option of using a search engine that doesn't do this and you will get different results.
Reliability is very important when you are searching on the Internet. Always ask yourself, “Is this reliable?” Don't make the mistake of believing everything you see. Some websites are unreliable and some information is false. Check your information on other websites before accepting it.
