When Jennifer brought her baby home from the hospital, her cherished dogs had very different reactions. Her Boxer, Sonya, was immediately gentle and protective. But Tiger, the Pomeranian, was less welcoming. "If any diapers or toys were on the floor, he peed on them," says the Greenbrier, mom. In the eyes of a pet, there's a new star in home who's stealing his spotlight. Even the gentlest animal will probably act up if he doesn't get his usual attention. These simple steps will help your pet adjust and keep your baby safe. Introduce Them with Care Your newborn and per's first encounter can set the tone for their relationship. To make it as smooth as possible, try this trick from Caryn Ruiz:"Before we left the hospital, my husband took blankets home to our dog, Daisy, so she'd know our newborn Devon's smell." When you get home, have your husband carry the baby so you can greet your pet without worrying about her jumping on you. A cat will likely walk away at first, while a dog probably wants to investigate right away. To introduce your baby, get down on your pet's level and let her have a hello sniff. Don't panic and pull your baby away unless your pet is barking or hissing, because it'll send the message that the baby is a threat. Learn the Safety Basics No matter how smoothly the introduction goes, there are certain safety rules you should follow. Never leave your baby alone with the pet. Even the gentlest animal can react unpredictably. Your baby's crying could frighten your cat, or your dog could suddenly become territorial. Consider setting up baby gates to limit your pet's access. To keep your cat from jumping into the bassinet , try putting mosquito netting over the top. Cats hate sticky paws, so keep the crib and changing table off-limits by lining the edges with sticky strips made for furniture. You can also train your dog to sleep in a crate . Question: According to the passage, to keep your baby safe, you should do the following things EXCEPT _ . - introducing your baby to your pet with care - leaving your baby alone with your pet at the first day when they meet - setting up baby gates to limit your baby - keeping your pet away from your baby

Q: Read the following article and select the best answer. Article: The capsized accident which happened in Yangtze River on June 1st, 2015 shocked the whole country.There are so many people related to this accident.Zhang Shunwen, the captain of the vessel , has been probably the person being mostly discussed now. Born in 1963, Zhang has been working on this ship for 35 years and became captain of it in 2007.Until the accident, Zhang was regarded as an effective captain and his experience as a sailor was flawless with numerous awards. Zhang Shunwen said the wind was coming from the South, and the wind then was about three to four grade.He first tried to ride the ship northward on the leeside in an effort to counter it with the vessel's speed.However, the wind suddenly gathered speed and he lost control of the ship."We couldn't fend off the wind even if we made a full left turn." he said. Zhang escaped alive and is under watching by police, although he has not yet been accused of any wrongdoing. Every person has his opinion toward this kind behavior of police. Some of them think of it to be improper because the captain himself is also a victim in this accident, what's more, his wife, who also boarded on this boat, remains missing now. While others are in support of this action, to them, it is the captain who should shoulder the responsibility. For me, I agree with the former. Because the captain has made every effort to deal with the accident. Question: According to the description of Zhang, the situation of the accident then is _ . - Fierce. - Calm. - Not so bad. - secure
A: Fierce.

*Question*
Read the following article and select the best answer. Article: A Train Floating On Air A train that floats on air? It's not magic--it's magnets .And it's close to reality. In Virginia USA the fall of 2002, a train with no wheels traveled on air and carried college students across their campus.In Japan, a whisper-quiet railway engine hovered and raced at 350 miles per hour using magnets and electricity as the power.And in China, a magnet train line linked Shanghai with nearby Pudong Airport. These trains use magnetic levitation technology, "maglev" for short. They use the same rules as the magnets you pick up at home or school: opposite poles of magnets attract each other, and like poles _ each other. How does it work? Powerful magnets on the bottom of the train repel magnets on the track, which is actually just a magnet-filled guiding way. With a magnetic field of sufficient force, the train will go hovering on air, which seemed impossible to us in the past. When an electrical current is sent through the track, the train moves. Turn the current backwards and the train slows down. Maglev doesn't rely on the friction of wheels on track, so it can climb a much steeper hill than a traditional train. And it can travel easily in snow and ice, something that could bring normal trains to a screaming stop. Question: What can we learn from the text? - A magnet-filled guiding way is formed inside a maglev train. - Instead of electricity, magnets are used as the power of a maglev. - Maglev trains can climb hills with the help of magnetwheels. - Electric currents decide the movements of a maglev train.
**Answer**
Electric currents decide the movements of a maglev train.
