I first began experiencing anxiety and depression at age 14 after being bullied(欺凌) at school for years. While at first anxiety and depression would come and go, it eventually became constant part of my life.

I was so set on finding the solution to overcoming it that I tried everything from when I was in college to graduate school：mood-changing medication, special teas, yoga, anything I read about in books, and advice given by doctors. Despite this, I still felt I hadn't even come close to managing the problem.

But one afternoon, I spotted an article in a magazine talking about how dogs were able to help people with anxiety and depression. The next day, I managed to get a dog—corgi(柯基犬).

However, once the "puppy excitement" went away, my anxiety and depression came back as usual. One morning, I woke up with those familiar feelings again. I didn't want to get out of bed. I turned to pull the covers back over my head and give up. That's when I saw my pet—Buddy.

Buddy started jumping all over me, licking(舔) my face, and letting me know that it was time to go outside. It was as if he were saying, "There's no time to be sad! The world is amazing!" And for the first time in my life, on a day when my anxiety and depression were strong, I got out of bed. I put on my winter clothes and went for a walk in the snow with my new friend. I realized at that moment, walking down the street in winter, my life was changing. I was really a new girl.

Sure, I still have days when I feel down or anxious. But with Buddy by my side, I've finally learned how to manage these feelings and emotions.

A year ago, I decided to create a more environmentally friendly kitchen, focusing on reducing the single-use products such as plastic bags and paper towels. I'm not going to sugarcoat my experience. It takes commitment and a willingness to change long-held habits. In creating my kitchen, I tried a lot of different alternative products and some plain old common sense. The result, however, has been worth the effort. I'm recycling more and relying less on single-use products and I'm saving money too.

I'm not kidding when I say that I used to really love plastic storage bags, so this was, perhaps, the biggest challenge for me. Switching to reusable storage bags is a financial investment, but the cost is reasonable considering that I previously spent at least $ 100 annually on single-use plastic bags and wrap. I will check online periodically for recycling updates, where a zero-waste box for kitchen items is offered, from party supplies to mixed-material food containers.

I'm a clean freak (怪人) and used to go through an amount of paper towels on a daily basis, but it's easy enough to take old T-shirts or towels and cut them up to use to wipe down surfaces. I'm also a fan of bamboo paper towels, which have the look and feel of traditional paper towels, yet are made from a highly renewable source and also break down in just 45 days. Better yet, they can be reused up to 100 times. As for kitchen sponges (海绵擦), I keep an eye out for those made with natural and recyclable materials.

When purchasing household items online from companies like Amazon or Jet, I will ask to have them shipped in as few boxes as possible or as small a box as possible if a single item is to be sent. I'll let the company know that they should pay more attention to how it is packaging items for delivery.

1. （1） What is the author's main purpose of creating her kitchen?

   A . To reduce waste and recycle more. B . To save money.  C . To change her long-held habits. D . To make it cleaner and more practical.
3. （2） What does the underlined word "sugarcoat" in paragraph 1 mean?

   A . Get interested B . Make attractive. C . take place. D . Give up.
5. （3） In creating her kitchen, what does the author do?

   A . Chooses to use the recyclable or reusable kitchen items. B . Goes through an amount of paper towels on a daily basis. C . Checks online periodically to buy zero-waste box. D . Begins to recycle more single-use plastic bags.
7. （4） What can we learn about the author from the text?

   A . She prefers to have her purchases packed in small boxes. B . She is used to traditional paper towels. C . She has a good knowledge of financial investment. D . She has strong environmental awareness.

根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

The Internet has opened up a whole new online world for us to meet, chat and go where we've never been before.

But just as in face to face communication, there are some rules of behavior that should be followed when on line. Imagine how you'd feel if you were in the other person's shoes.

For anything you're about to send: ask yourself, "Would I say this to the person's face? ". If the answer is no, rewrite and reread.

If someone in the chat room is rude to you, your instinct (本能) is to fire back in the same manner. But try not to do so. If it was caused by a disagreement with another member, try to fix the situation by politely discussing it. Remember to respect the beliefs and opinions of others in the chat room.

Offer advice when asked by newcomers, as they may not be sure what to do or how to communicate. When someone makes a mistake, whether it's a stupid question or an unnecessarily long answer, be kind about it. If it's a small mistake, you may not need to say anything. Even if you feel strongly about it, think twice before saying anything. Having good manners yourself doesn't give you license to correct everyone else. At the same time, if you find you are wrong, be sure to correct yourself and apologize to those that you have offended.

It is not polite to ask others personal questions such as their age, sex and marital status. Unless you know the person very well, and you are both comfortable with sharing personal information, don't ask such questions.

A. You should either ignore the person, or use your chat software to block their messages.

B. If you do decide to tell someone about a mistake, point it out politely.

C. Repeat the process till you feel sure that you'd feel comfortable saying the words to the person's face.

D. When you send short messages to a person online, you must say something beautiful to hear.

E. Everyone was new to the network once.

F. The basic rule is simple: treat others in the same way you would want to be treated.

G. It's natural that there some people who speak rudely or make mistakes online.

I remember the first day when I saw Sally playing basketball. I watched in wonder as she struggled her way through the crowd of boys on the playground. She seemed so1, but she managed to shoot jump shots just over their heads and into the net. The boys always tried to stop her2nobody could.

I began to notice Sally at other times, basketball in hand, playing3. She practiced dribbling(运球) and4over and over.

One day I asked Sally why she5so much. Without a moment of hesitation she said, "I want to go to college. The only way I can go is to get a 6.
