  Dogs are wonderful companions, but there're some breeds(品種) more challenging to live with and to train. Some breeds are not the best choices for new trainers or owners.

  However, if you compare the numerous breeds which are more difficult to train,you'll find differences of opinion, probably based on individual experiences with individual dogs. It's im?portant to remember differences in individual dogs. If you're a novice owner or trainer,talk to a good breeder or trainer. You may need to adjust your choice of dog or adjust your training meth?od. Here,re a few other points to consider：

  High-energy dogs can be a training challenge, especially if they don't have sufficient op?portunity to burn off that energy before training sessions.

  Don't assume that a dog is dumb just because they're a challenge to train. If you find the

right method and if you're realistic in setting your training goals, most dogs will be more than willing to learn,although it may take some longer to learn than others. Listing a particular breed as being difficult to train may lead owners to assume that their dog can't be trained or that their dog is somehow less intelligent.

  Some breeds were bred to work independently，and may not be interested in a lot of inter?action with their owners.

  Other breeds are so highly tuned into their particular skill that at times it's very hard for them to focus on anything else.

  Dogs bred to be vocal―guard dogs，dachshunds or hunting hounds―will be more difficult to be taught that barking is unacceptable.

  Finally，any dog breed can be a challenge to train if you are attempting to train for some?thing other than what they were bred to do or that they are physically able to do. Pugs and Bull?dogs probably won't do well with scent(嗅覺(jué)) work―their noses and brains aren't wired that way. Working dogs need jobs to do or you will never train them to stop destroying the house if you leave them for hours at a time. Don't adopt a dog simply because you like the breed;mak?ing sure your dog won't be a challenge to live with and to train is as much about selecting the right breed and the right individual for you,your lifestyle and training abilities. 

(   ) 5. This passage is mainly about .

   A.how to train different dog breeds

   B.some challenging dog breeds to train

   D.different kinds of famous dog breeds

   B.Trainers with different experiences all think it's really challenging.

   C.It's not really so difficult for some trainers with proper methods.

   A.it hates being trained with its owner

   B.it hates staying alone at home

   C.it can work very well without its owner

   D.it is pleased to stay with its owner

(   ) 8. What can we learn about breeding and training dogs from this passage?

   A.Trainers can never let any dog burn off its energy before it's trained.

   B.If it's hard for you to train a dog,the dog is most probably dumb.

   C.it's difficult to train dachshunds to not bark because they like barking nature.

   D.All dogs will probably destroy the house if they have nothing to do.

 Kids have less safety sense. Though it is difficult to stop the children from suffering inju?ries,we can always take measures and learn the first aid available in case of an emergency. Lis?ted below are a few tips on first aid and safety which should be paid attention to.

  Tragedy involving fire is the worst and safety methods taken to prevent these things from happening are the best. Educating children on measures to prevent fire is the first step towards fire prevention. The next step is to operate tire items with care. Children should not be allowed to cook or operate a gas stove alone. Fire drills can help children learn the methods of escape in case of a fire. In case of burns of low intensity(強(qiáng)度) ，run cold water until the pain disappears; however, with serious burns,you must seek medical help immediately. Also make sure that there are enough smoke alarms installed in the house.

  Another major fear involving kids is drowning. The children should never be left unattend?ed while swimming, even if your child is a great swimmer, if a girl has long hair she must make sure that she ties it firmly in the swimming cap before swimming to prevent it getting tangled (纏繞) in the pool. Take measures by making children wear lifesaving jackets and stop them from going to any place like the docks where water is dangerous to swimmers.

  Carbon dioxide is poisonous especially to children. Even a small dose of it can be fatal for them or at least has the power to make a child seriously ill. Place all medicines and other poison?ous substance away from the reach of children.

  Cuts are common among children, but parents can avoid it by making their children wear shoes at home and removing any furniture with sharp edges. Avoiding injuries is as important as learning first aid.

(   ) 1. From the passage we can learn that .

   A.it's hard to pay attention to children's safety

   B.there're no ways to stop children suffering injuries

   C.if we take measures few injuries will happen

   D.children's suffering injuries is easy to happen

(   ) 2. What should we do first of all according to the author?

   A.We should let children know it is dangerous to cook or play with fire.

   B.We should have children know tragedy involving fire is the worst.

   C.We should make children master the measures to prevent fire.

   D.We should teach children how to operate fire items with care. 

(   ) 3. What is the author's opinion about children's doing cooking?

   A.Children should not be allowed to cook.

   B.One must keep watching as his kid is doing cooking.

   C.Children should be told to cook by himself.

   D.Parents should teach their children how to cook.

(   ) 4. Children need to study fire drills in order that they can        .

   A.learn how to deal with burns

   B.learn how smoke alarms work

   C.take effective measures against fire

   D.escape when a fire breaks out
