I was determined to learn swimming at the age of ten. At the K. P. L. B．was a pool offering the
opportunity. The K. P. L B．pool was quiet. I was afraid of going in all alone, so I sat on the side of the pool to wait for others. Then came a big boy. He yelled, “Hi, Skinny! How’d you like to be ducked?” With that he picked me up and threw me into the deep end. I landed in a sitting position, and swallowed water. ____17____ I gathered all my strength when I landed and made what I thought was a great spring upwards.

It can be painful when you feel like your parents are treating your siblings (兄弟姐妹) better than you. If you feel really sad about this, the following steps can help you improve the situation. ____21____
Since we’re all unique, nobody relates to any two people in exactly the same way. Sometimes a parent might appear to favor you in some situations and favor a sibling in others. No parent can be perfect, but they should do their best to be fair. It’s normal for parents to treat each child little differently, because each kid might benefit from a slightly different approach.
Try telling your parents how you feel.
Your goal is to communicate your feelings directly without being rude.____22____For example, saying “I feel ignored ”is better than saying “you’re ignoring me.” You can also say,“I feel left out lately. Sometimes I feel like you're so busy taking care of the baby that you don’t have enough time for me.”
Ask for what you'd like to happen.
____23____This lets them know how they can try to fix the problem. Present an idea that could help. You can say,“Could you please try to show up to more of my games so that I'll feel so happy knowing you’re there to cheer me on.”
Step away if things get heated.
Maybe you or your parents will get angry. It’s hard to have a useful conversation if one or both people are too angry to think straight. If you see this happening, take a break. Do some deep breathing and step away.____24____
Remember that your parents have to make the decision to change.
Sometimes talking about your feelings is enough for them to change their
behavior.____25____This typically isn’t your fault (错误). The way they react to an honest conversation says how good they are at parenting, not how good you are at being their child. You can’t change other people. You can only control your own behavior.

B．Use “I” language instead of “you” language.
C．Keep in mind that every relationship is different.

Sharks take up the top position on the food chain in the ocean. As sharks die off, the population of the animals that sharks consume will increase. This, in turn, means that the number of the creatures those animals eat will drop. ____27____ Fish that eat algae (藻类) are also included. This can cause algae to spread so much that it damages coral reefs.
____28____ The ocean not only produces more oxygen than all the rainforests on Earth combined, but also removes half of the man-made greenhouse gas from the atmosphere. Once sharks die off, the global ecosystem will be upset, affecting all creatures including human beings. Don’t use shark products
First, vitamin energy drinks and leather goods can be made from shark parts. ____29____ In addition, shark meat is sold around the world, sometimes under misleading names such as rock salmon or whitefish.

Online scams (诈骗) are targeted at people from all walks of life. ____31____, and no one can stay safe without learning how to avoid them. Here are some of the tips to keep you safe from online scams.
1. Accept that online scams exist
Every time you start dealing with an unknown person or a contact online, you must consider it a possibility that you're dealing with a scammer. ____32____. Nothing in this world comes free, and everything has a price. So, if one fine morning you receive an email message about winning a million-dollar prize, chances are very high that it's an ugly trap.
2.Choose passwords carefully
You must choose difficult passwords while updating them from time to time. ____33____. And always avoid using the same password for different accounts.
3. Don't click what you don't know
A classic style followed by scammers is to send you Trojan horses in emails or messages.
____34____. In addition, you can use a Virtual Private Network that blocks access to bad pages and pop-ups.
4.____35____
If you ever have doubts in your mind about the intentions of an unknown person, you should first carry out an in-depth search online based on the basic information they share. If you ever receive a request for money from a friend, always call them up to check first.

In recent years, science fictions are becoming increasingly popular. Science fiction writers using their magical imagination create imaginary worlds that attract a great number of readers especially teenagers. But how can they make it so believable? ____36____
The way things work in your imaginary worlds will be based on actual science. So you must be familiar with the scientific laws related to your creation. If you’re writing about humans living on a planet with zero gravity, then you need to know the effects of zero gravity on the human body. ____37____ Only in this way can you gain the readers’ trust.
Then the rules in your creation can be different from our daily life, so you have to figure out the exact rules of your imaginary worlds. ____38____ For example, if humans in your creation are able to breathe underwater in Chapter 1, your characters can’t drown(溺水)in a swimming pool or river in Chapter 3.
____39____ You should decide the following issues: the history of the world, the geography, what possibilities it offers, how everything works in this new reality, as well as how all of these factors affect the way your characters think, feel, and react. You d on’t have to tell your readers all the rules in the first chapter. But you have to let readers know enough to understand what’s going on.
When you are writing, remember to make it feel real. You are creating a new real world for the readers. ____40____ Th ey are able to see, hear, feel, smell, and even taste what it’s like in the new world. Whether your novel is about a world without disease or an undiscovered planet, help
your readers feel like they’ re actually there.

B．You are inviting them to visit the new world.
C．You have to get rich imagination to create science fictions.
D．Make sure what you are writing is not against basic science.
E．Characters in the imaginary worlds always have super power.
F．Here you will find the answer if you are longing to create one.
G．Your preparation work also involves planning everything in great detail.
You just came back from lunch so you know you can’t be hungry. Yet, you are reaching for a bag of chips or a bar of chocolate as you prepare to work on a project which has been causing you stress and anxiety. ____41____
Most of us tend to overeat when we’re feeling stressed or under a lot of pressure. When under long periods of stress, our bodies produce cortisol, a hormone (荷尔蒙) that causes hunger.
____42____ In addition, the hormone causes our bodies to react favorably when we consume (消耗) foods that are high in fat or sugar, or both. These foods, known as comfort foods, do control stress in the short term, which explains why many of us desire for them.
Stress eating may be a conscious (有意识的) or unconscious decision, but it does pose (引起) several problems.
Physical health concerns of stress eating
Consuming an unnecessary number of unhealthy foods that are high in fat and sugar will contribute to weight gain. ____43____ What’s worse, it can lead to various chronic health illnesses such as high blood pressure.
Emotional concerns of seeking comfort foods
____44____ However, it does not actually solve your problems. Instead of looking for practical solutions to a stressful situation, your attention is focused on getting quick relief with food. These short-term relief measures may actually translate into a long-term emotional burden and affect your mental health.
Mental health concerns of anxiety eating
Eating to deal with stress and anxiety can easily become an unhealthy habit and may even lead to eating disorders. If left unchecked, stress eating may progress to binge-eating disorder.
____45____ However, it is neither a healthy nor a permanent solution to deal with a stressful situation. There are still many other methods of helping you fight stress and anxiety without sacrificing (牺牲) your physical and mental well-being.
A．That’s stress eating.
B．This poses a risk of being overweight.
C．This affec ts a person’s food preferences.
D．Stress eating can provide relief in times of stress.
E．Stress eating can provide emotional and mental comfort.
F．Seeking comfort in food may give you short-term stress relief.
G．It doesn’t work for the benefit of your body shapes in the long term, though.
Sometimes we just can’t avoid a discussion turning into an argument. If you do start arguing with someone.it is important to keep things under control and there are ways to do this.
The most important thing: don’t raise your voice. That will just make the other person lose their temper too.____46____ Say “I’m sorry” and continue to talk calmly and quietly, and then your partner will be more ready to think about what you are saying.
____47____ Try to keep to the topic you are talking about. Just concentrate on solving the one problem you are having. For example, if you’re arguing about the housework, don’t start talking about mobile phone bills as well.
And my final tip is that, if necessary, you can call “Time out”, like i n a sports match. If an argument is getting out of control, you can say to the other person, “listen, I’d rather talk about this tomorrow when we’ve both calmed down”. You can then continue the discussion the next day when perhaps both of you are feeling less tense and angry.____48____ Also, you may find the problem much easier to solve when you’ve both had a good night’s sleep.
I want to say one last important thing. ____49____ This is not true. Conflict normal part of life, and dealing with it is an impor tant part of any relationship. If you don’t learn to argue properly, then when a real problem comes along, you won’t be prepared to face it together. Think of the smaller arguments as training. Learn how to argue cleanly and fairly. ____50____
A．It is also very important to stick to the point.
B．Some people think that arguing is always bad.
C．You may believe that arguing is impossible to avoid.
D．The second thing is that you should find a good topic.
E．It will help your relationship become stronger and last longer.
F．You are more likely to reach an agreement when you are both calm.
G．If you find yourself doing this, stop for a moment and take a deep breath.

知，本段是描述鲨鱼制品，B项“鲨鱼油也被用于许多流行的美容产品中”符合语境，故选B 项。

牝30、根据上文“Fishermen cut the shark’s fins off and then throw the shark back into the water, still alive.(渔民割下鲨鱼的鱼鳍，然后把还活着的鲨鱼扔回水中)”可知，被割掉鱼鳍的鲨鱼被扔回海里，结合下文“Sharks breathe by swimming, so a shark that can’t swim will die.(鲨鱼通过游泳呼吸，所以不会游泳的鲨鱼会死亡)”可知，没有鱼鳍的鲨鱼不会游泳，所以几天就会死亡，C项“然后鲨鱼慢慢死去，有时会持续几天”符合语境，故选C项。
