[河北石家庄二中2021高二月考]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 sugar-coat my experience. It takes commitment and willingness to change long-held habits. In creating my kitchen，I tried a lot of different alternative products and some 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 can break down in just 45days.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 to pack items for delivery.

Tips for Teaching Students With an Emotional Disturbance
Emotional disturbances refer to a variety of disorders and conditions, such as anxiety disorders, conduct disorders, mood disorders, and eating disorders. Teaching in a classroom with one or more students with an emotional disturbance can feel stressful. However, there are strategies that teachers can employ to help reduce their frustration and increase their students' success.
Know Your Students
Not all students with an emotional disturbance will demonstrate the same behaviour. Understanding your student's specific disorder and how it affects him will better enable you to provide proper support. 1
Communicate With Parents
2 Parents can help you understand the specifics of how your student is affected by his emotional disturbance. Frequent communication with parents will also help you stay aware of what's going on at home that could be affecting your student in the classroom.
3
While clear and concise classroom rules benefit all students, they are especially useful for students with an emotional disturbance. State the classroom rules in a positive manner. Review the rules periodically and keep them posted in the classroom where students will be sure to see them every day.
Maintain a Routine
Besides classroom rules, posting a classroom schedule will help maintain structure and organisation in the classroom. 4 But knowing what's coming and when it is coming will help them move from one activity to another without incident. Knowing the classroom schedule helps students prepare and will reduce instance of confusion among your students.
5 This will help reduce your frustration, and students with an emotional disturbance will be given more opportunities to succeed.
A. Create Clear Classroom Rules
B. Get Along Well With Your Students
C. It's important to stick to the schedule.
D. Nobody knows your student better than his parents.
E. Some students with an emotional disturbance may struggle with change.
F. Following these tips will help you create meaningful relationships with your students.
G. Knowing your students personally will also help you to create a more effective educational environment.

[湖南湖湘教育三新探索协作体2021高二联考]阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
It was a Monday and Khan，a pet dog，had joined the family the previous Friday. He had already decided that two-year-old Charlotte was his No.1 girl. The dog had seldom left her side since arriving at his new home.
Khan was next to Charlotte when Catherine took her into the garden for some fresh air. “I was just in the house doing boring mother things and Charlotte wanted to go outside and run around，"she says. “We were just walking around the garden looking at flowers and all that good stuff. Khan was with her."
Charlotte was soon tired of playing in the garden and then went to play the padlock on the gate. “She was beating the padlock and it was banging on the gate，"Catherine recalls. She thought Khan，who was naturally right next to Charlotte，might be disturbed by the loud noise，but he seemed undisturbed by it. That was until，entirely without warning，he became very upset indeed.
“Khan suddenly started making this noise from the depths of his chest，this growl，"she says. “His whole chest puffed up，his hair stood up，and he lowered his head. He continued to make this growl."
As Catherine watched，Khan seemed to double in size. "He kept trying to push her. I was right next to Charlotte-no more than a metre away and I thought，‘He's going to hurt her'. His chest was bigger than he was long，” she says.
Time seemed to slow down as Catherine rushed desperately to save her daughter. But Khan got to Charlotte first. He grabbed her by the back of her clothes and threw her over his shoulder into the garden. “I turned and looked and she was just sitting there in a pile of grass." Still not certain whether Khan's strange behaviour was some sort of attack on her child，Catherine raced to pick up Charlotte，who was completely unharmed，and take her inside for safety. Just as she turned to run into the house，Catherine saw a big brown snake bite Khan right in the chest and slid away quickly.
