You will have more success if keep your fingers spread moderately apart when swiping. Speak screen can also be enabled by starting Siri and saying "speak the screen". You can pause, play, back up, and fast forward, as well as change the rate of speech. Speak screen will not work when there is no content. For example, starting Speak Screen while on your Home screen will not work, as Speak Screen does not read your app names. Press the "<" button to return to your device while continuing to have the screen read aloud. When using Safari in iOS 8, you'll see a small button to the left of the address bar that will open the Speak Screen menu. This is more useful than using the swipe method because the swipe method will read all of the hidden HTML tags, possibly making it difficult to understand. Unlike Speak Selection, Speak Screen will automatically turn the pages of your book, allowing you to listen to your books being read to you while you work with other apps.

Q: A clicker is a small plastic box that contains a strip of stiff metal. When pressed, the metal makes a distinctive "click-clack" noise. Clickers can be obtained in most pet stores.  The theory behind clicker training is that the cat will learn to link a sound (click-clack) with a reward (tasty treat). The nice thing about a clicker is that it is a distinct sound which is only associated with a reward. Thus, the cat is much more likely to respond.  Although you can train a cat using just words, it can be more difficult. Because you use words in everyday speech not directed at your cat, the cat probably won't pay a lot of attention to them. Furthermore, if you use a command word such as "shake," the cat will likely hear the word in other contexts and not know when it is expected to respond. Cats can be picky eaters, and a treat that one cat enjoys may be of little interest to another. Training will go faster and more easily if you determine in advance what kinds of treats your cat enjoys most. You may want to try buying a small amount of several different cat treats to try them out and see what your cat likes best. The ideal time for a clicker session is when the cat is relaxed but not asleep, and sitting near you. You can start any time when the cat is paying attention. If your cat has just woken up, it may be groggy. If this is the case, give the cat five minutes or so before you begin training. Once the cat looks alert, press the clicker and give it a treat. Repeat this several times over a period of about five minutes. Cats only  have a short attention span, so don't try to continue your clicker session beyond about five minutes. Later in the day, or the next day, do another clicker session. Continue repeating these sessions regularly until your cat associates the sound of the clicker with a treat.  Each cat learns at a different pace, but most will figure out the link between the clicker and the treat after two or three five-minute sessions. Be consistent, repeating the clicker session once or twice a day, every day, until the cat makes the association.  You will be able to recognize when your cat has discovered the connection, because it will gaze at you expectantly and perhaps lick its lips after your press the clicker.
A: Obtain a clicker. Find a treat your cat enjoys. Pick a training time. Train with the clicker. Repeat the session.

Article: Traditional dizis are made of bamboo, while historically, dizis and other flutes have been made from bone, jade or other stone, or pottery. Be sure to take into account being able to acquire and prepare the materials. Choose a piece of material that is about ¾” to 1” in diameter. Bamboo is the ideal material for a homemade dizi, as it is easy to acquire and easy to manufacture into a dizi. It is also lighter and will likely be easier to play, which is useful if you are a beginning player. Bamboo can come from a regular bamboo plant with any extraneous leaves removed, or you can repurpose another bamboo object, such as an old bamboo fishing rod. There are different strains of bamboo that can be used; purple bamboo is typically used in the northern regions of China, while white bamboo is typically used in southern China. The size of the flute will determine the musical key in which it plays. Flutes are typically available in the following keys (from longest to shortest): F, G, G#, A, A#, B, C, C#, D, D#, E, F and F#. A good length is approximately 18-20” long. Longer flutes may have an additional finger hole (the larger dizi has this), and they play lower octaves. Small flutes with higher octaves are smaller than 16”, while longer flutes are ideally 24-26” long. Choose ringed ends, capped ends, or no ends for the dizi. These will determine how long-lasting your flute is, as well as how susceptible to cracking or molding it may become. The materials for the capped or ringed ends, called ferrules, can be made of brass, bone, plastic or wood.  Ringed ends: Some flutes have a brass ring around the end. This helps the flute (especially those made of bamboo or other wood) from cracking. Moisture can get underneath the ring, however, and cause molding. These can also be installed on a flute that did not previously have a ring in order to stop a crack from getting bigger. Capped ends: These ends are often made from plastic, cow bone or horn. Flutes with capped ends typically make brighter tones. Moisture can get underneath the cap, however, and cause molding. No ends: You do not need to have any rings or caps on the end of your flute. Instead, you can paint the ends to add decoration, or you can leave them bare. However, bamboo flutes especially may be susceptible to cracking more easily than flutes with ringed or capped ends. Find the correct size of plastic or metal ring or cap to fit this diameter at a hardware store. If you are not using any ends, you can also opt to wrap string around the dizi to prevent cracking.
Question: What is a summary of what this article is about?
Select the type of material for the dizi’s body. Choose the size of your flute. Determine the style of ends for the dizi. Carefully measure the outside diameter of your flute body.
