Do you remember your first day of school? Were you excited or a bit scared? When I started school, I lived in an area of southern Germany. I remember how frightened I was, mostly because I didn’t know what to expect.
My mother and I walked quietly, downhill into the center of town. When we entered the classroom, I noticed all the children were sitting quietly in their seats. Anxiously, I picked a spot next to a friendly–looking girl.
In my nervousness, I had totally forgotten I was to receive a Schultuete (school cone) on the first day of school, but as I looked at my teacher's desk I remembered. Her desk was covered with huge cardboard cones. I knew that my mother had filled my Schultuete with goodies and brought it to my classroom the day before, but I didn't know which one was mine.
That morning, the focus of my attention remained with those cones. All of the fear slowly disappeared. When the teacher asked me to approach the desk, she did not seem threatening at all. When she smilingly handed me my Schultuete, I was the happiest girl.
Proudly, I carried my gift home. The hill did not seem steep at all. Hurriedly, I unwrapped my Schultuete and discovered candies, chocolates, and oranges. This day stayed in my mind as one of the sweetest in my life.
When I was older I asked my mother about her first day of school. She told me she hadn't received a Schultuete from her parents because the custom had not been established all over Germany at that time.
The custom began in the cities in the 1800s and then spread to the towns and villages. By the early 1950s, the tradition of the Schultuete was established all over the country. And it has been passed on even in the present day.
25.How did the author feel at first about her first day of school?
A. Excited
B. Confused
C. Afraid
D. Delighted
26. According to the text, a Schultuete _____.
A. is given to kids as a gift on their first day of school
B. is presented as a reward by a school teacher
C. became popular in the early 19th century
D. is usually filled with school supplies
27. The underlined sentence “The hill did not seem steep at all” implies that ____.
A. the author was in good health
B. the author was very excited then
C. the author enjoyed climbing hills
D. the author missed her mother badly
C
A sea turtle named Herman, an octopus called Octavia, and a seal named Lidia all spent this summer at the Smithsonian’ s National Zoo in Washington, D.C. But unlike the zoo’s other residents, they are not real animals. These creatures are actually huge sculptures and they’re made entirely out of plastic trash from the ocean.
These giant artworks, along with 14 others, are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by artist Angela Haseltine Pozzi, works to raise awareness about the problem of plastic pollution in E arth’s oceans.
More than 315 billion pounds of plastic litter the world’s oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces. It often collects in spots called garbage patches, which spread over large areas of the ocean.
Thousands of marine animals----including whales, sea turtles, and fish----die each year from eating or getting stuck in plastic bags and other items. Plastic pieces can also injure coral and kill sea grass.
Washed Ashore and other organizations are working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38,000 pounds of plastic trash from more than 3000 miles of beaches. They helped Pozzi create more than 60 sculptures of marine creatures that were harmed by plastic pollution.
The artworks on display at the National Zoo include a 20-foot-long coral reef, a 12-foot-long shark, and a 16-foot-long parrot fish. Each one is made from hundreds of pieces of trash like water bottles and sunglasses.
“These sculptures are a powerful reminder of our person al role and global responsibility in preserving biodiversity on land and in the sea,” says Dennis Kelly, director of the National Zoo.
28. Why is Angela exhibiting her sculptured animal?
A. To prove her talent in sculpture.
B. To attract most visitors to the zoo.
C. To care about the plastic pollution in seas.
D. To teach the people the use of plastic.
29.What is stressed in Para. 3 according to the text?
A. Why plastic is difficult to break up.
B. What problems plastic litter causes.
C. Where plastic pieces go at last.
D. How garbage patches are formed.
30.What are Washed Ashore volunteers doing?
A. Collecting pollution trash from the beaches.
B. Turning trash from the ocean into art.
C. Raising 38,000 pounds for plastic pollution.
D. Surveying the data of plastic litter in oceans.
31.Which of the following best describe Dennis Kelly’s attitude to Pozzi’s sculpture?
A. Doubtful
B. Supportive
C. Negative.
D. Indifferent
D
Reading instruction in the classroom is a key concern for all teachers and there are many ways to go about it. However, is our determination to achieve excellence in reading skills in our children killing their love and enjoyment of a good book?
In my work with parents, I am frequently asked the best ways to encourage reluctant readers to be engaged with books. Parents report that their children return home from school with no inclination to pick up a book and read.
Any eager reader will gladly talk about the joy with a good book to read away the hours on a cold, rainy afternoon. Reading a good book is one of life’s greatest pleasures. We need to share these experiences with our children in order to assist them in developing into strong readers. But the use of boring, mass-produced ho me reading texts in children’s early years at school can be seen as the beginning of this negative cycle.
As children progress through their schooling life, there are many other instances of learning reading skills that don’t help reading development. Freq uently, teachers feel the pressure to give their students “ just enough” in terms of reading strategies to be able to achieve the test, which leaves little
time to focus on reading for pleasure.
Kelly Gallagher, a high school teacher, outlines the term” Readicide” in his book. He says it’s: the systematic killing of the love of reading, often worsened by foolish, boring practices found in schools.
Recent research shows that many teachers tend to follow the traditional literacy practices that they have experienced in their own education, which can often have negative intentions for their students.
While teaching children key concepts for analyzing and evaluating texts is important, the manner in which it is done and time that is spent on this can lead to unex pected results. Schools aren’t to blame when it comes to not arresting students’ lack of interest in reading, but they have an important role to play in fostering reading enjoyment.
32.What does the underlined word “inclination” mean?
A. Energy
B. Task
C. Intention
D. Requirement
33.What does the term “Readicide” refer to?
A. To develop reading habits
B. To read for pleasure
C. To learn reading skills
D. To kill a love for books
34.According to the text, teachers at school ______.
A. focus on teaching reading strategies
B. ignore key concepts for analyzing texts
C. are to blame for students’ poor reading
D. fail to follow the traditional reading practices
35.What might be suitable title for the text?
A. Reading books is to experience pleasure
B. Learning to love books is even more important
C. Teaching reading helps reluctant readers
D. Getting pleasure from books makes capable readers

5 Things I Wish I Knew Freshman Year
During my freshman year of college, there were a few things I learned along the way that I wish I had known right from the beginning. 36 . Below is a list of 5 important things any freshman should know, from day one.
1. 37 .
It’s okay to miss your best friend forever from home, or to try to make it work long distance with your high school boyfriend… But don’t be lost in high school (and leave the drama behind). Meet new people, make new friends and most importantly keep an open mind when it comes to your high school relationship. If you feel like you’re crushing on someone else, explore the opportunity!
2. Always use student discounts.
Now that you’re in college, you shouldn’t pay full price for any thing you buy. Sign up for Student Card to enjoy discounts at Forever 21, Urban Outfitters, Lenovo, and many more. When you go to the library, or grab a pizza in town, always ask if the store offers a student discount.
38 .
3. Don’t be spellbound by your Instagram self.
39And you’re hoping your high school friends are watching…, but put away your phone once in a while and enjoy the moment! Also be mindful of what you’re sharing online. Do you really want your future employer, or your 15-year-old cousin to see you shotgun a beer on Instagram?
4. Try not to skip too many 8 am classes.
If you’re going to skip your 8 am class because it is too early, pick a later class. I know what you’re thinking, “I took morning classes in high school and I was fine.” It’s not the same, try to avoid these classes.
5. Get out of your comfort zone!
40 Take risks things, explore your passions, meet new people and smile! Remember, if it’s not going so well at first, you have three years to find something on campus you like and if you are enjoying yourself, be sure to spend your time wisely as four years go by quicker than you could ever expect!!
A. Almost every store does
B. Start off the year doing stuff right
C. Don’t stay stuck in high school
D. You want to share with the world how cool your new life is
E. Lastly, remember, college is only four years long
F. Don’t be afraid to ask for help, as it can make a big difference
G. So instead of going through the process yourself, I think I’d make things a bit e asier

How to Communicate With Our Parents
Hello, everyone, I’d like to share my ideas about the topic of communicating with our parents.
Parents are the people devoted to us most, and that’s why it’s necessary to keep a good relationship with them. Here are my ideas on how to make it easier to communicate with parents.
First, we should respect and trust our parents. Don’t be rude to them even if they have done something wrong. They have experienced more and always try their best to protect us from dangers. Second, if we often share with them our life and experiences, we will know each other better. What’s more, we can often tell our parents how much we love them. If sometimes we don’t agree with our parents’ decisions, we should try to put ourselves into their shoes and we will soon understand them. Please do remember they really hope that we will become the best in the future.
Thank you for listening.
