input: Belgrade is the capital and largest city of Serbia. It is located at the confluence of the Sava and Danube rivers, where the Pannonian Plain meets the Balkans. Its name translates to "White city". The urban area of the City of Belgrade has a population of 1.23 million, while over 1,68 million people live within its administrative limits.

One of the most important prehistoric cultures of Europe, the Vinca culture, evolved within the Belgrade area in the 6th millennium BC. In antiquity, Thraco-Dacians inhabited the region, and after 279 BC Celts conquered the city, naming it "Singidun". It was conquered by the Romans during the reign of Augustus, and awarded city rights in the mid-2nd century. It was settled by the Slavs in the 520s, and changed hands several times between the Byzantine Empire, Frankish Empire, Bulgarian Empire and Kingdom of Hungary before it became the capital of Serbian king Stephen Dragutin (12821316). In 1521, Belgrade was conquered by the Ottoman Empire and became the seat of the Sanjak of Smederevo. It frequently passed from Ottoman to Habsburg rule, which saw the destruction of most of the city during the Austro-Ottoman wars. Belgrade was again named the capital of Serbia in 1841. Northern Belgrade remained the southernmost Habsburg post until 1918, when the city was reunited. As a strategic location, the city was battled over in 115 wars and razed 44 times. Belgrade was the capital of Yugoslavia from its creation in 1918. 1. What is the main subject?

input: In a telephone call Monday between Russia's Defense Minister General Sergei Shoigu and the U.S. Secretary of Defence Chuck Hagel, Shoigu described the activity of U.S. and NATO troops near Russia's border as "unprecedented."

According to the official Russian version of the call, his American counterpart assured him the alliance did not have "provocative or expansionist" intentions -- and that Russia should know this.

But it hardly seems to matter how often NATO makes these assurances. The Kremlin will never trust them. Fear of the Western military alliance's steady march east is deep-rooted. It strikes at the very heart of Russia's national sense of security, a relic of Cold War enmity which has seeped down to post-Soviet generations.

Ilya Saraev is a 15-year-old pupil at the First Moscow cadet school in Moscow. He thinks long and hard when I ask him about NATO. "I think NATO might be a friend to Russia but there's one point I don't understand: Why it needs to approach the border with Russia more and more," he says.

Cadet school is an education in patriotism, like something from a bygone era. Besides the regular classes, there are lessons in ballroom dancing. Teenage cadets proudly leading local beauties through the waltz while outside their classmates rehearse the goosestep.

After the takeover of Crimea, U.S. Secretary of State John Kerry accused Russia of behaving in a 19th century fashion in the 21st century. In some ways it's an epithet that seems to ring true here. The children are immaculately mannered and thoughtful. They write to their fellow cadets in Crimea. They say they feel sad there's this tension between brother nations -- Russia and Ukraine. 1.

input: Lucy was a young lady bug. She always felt different from the lady bugs because her colors were reversed! Instead of a red body and black spots she had a black body and red spots! As you can imagine this left Lucy feeling pretty lonely so she spent a lot of time flying around to all the different areas to find other ladybugs like her. She loved to feel the wind in her wings as she flew. She spent so much of her time flying around so she could fly longer and faster than another other lady bug. She also loved flying so much because it gave her a feeling of being free. One day when she was flying around she heard a loud scream for help! She went as fast as she could towards the screams for help. She saw another lady bug with a broken wing lying on the ground. She knew the lady bug as Jessie. "What happened?!" asked Lucy. "I crashed into the tree flying home yesterday and I've been lost ever since. I can't fly because my wing is broken. Do you know the way back home?" asked Jessie "Don't worry Jessie, I know this area like the back of my wing I'll lead you home!" Lucy said happily. "Thank you so much!" Jessie said happily. Lucy led Jessie straight home where he was given medicine to fix his broken wing. She was rewarded a medal and called a hero.
