Most children who have suffered from ADHD still have it as teens. During teen years, especially as the hormonal changes of teenagers are going on and the demands of school and extra-curricular activities are increasing, ADHD may get worse.
Because of problems with getting unfocused and poor concentration, many teens with ADHD have problems in school. Grades may fall, especially if the teen is not getting ADHD treatment. It’s not uncommon for teens with ADHD to forget their homework, lose textbooks, and become bored with their daily class work. Teens may become inattentive or extremely attentive, not waiting for their turn before blurting out answers. They may cut in on their teacher and classmates. Teens with ADHD may also befidgetyand find it hard to sit still in class.
Often, teens with ADHD are so busy focusing on other things that they forget about the task at hand. This can be seen especially with homework and athletic skills and in relationships with their schoolmates. This lack of attention to what they’re doing often leads to bad grades on tests and being passed over for sports teams, after-school activities, and learning teams. Kids with ADHD can be targets for bullying, too. But, not all children with ADHD have trouble getting along with others. If your child does, you can take measures to help improve their social skills and relationships.
ADHD affects all parts of a teenager’s life. As a parent you should discover your teen’s troubles as early as possible. The earlier your child’s troubles are discovered, the more successful the following steps can be.

This year researchers expect the world to snap 1.35 trillion photographs, or about 3.7 billion per day. All those pixels (像素) take up a lot of room if they are stored on personal computers or s phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted to protect its data, cloud storage users have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt (加密) images stored on many popular cloud services while allowing authorized users to browse and display their photographs as usual.
Malicious (恶意的) attempts to access or leak cloud-based photographs can expose personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some users' private videos with strangers. Security experts also worry about employees at cloud storage companies on purpose accessing users' images.
So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”
To overcome this problem, they created a tool that preserves blocks of pixels but moves them around to effectively hide the photograph. First, ESP's algorithm (算法) divides a photograph into three separate files, each one containing the image's red, green or blue color1 data. Then the system hides the pixel blocks around among these three files (allowing a block from the red file, for instance, to hide out in the green or blue ones). But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy black-and-white ones to anyone who accesses them without the decryption (解密) key.
8. What's probably the main purpose for people to store images in the cloud?
A. To save storage room.
B. To make photos beautiful.
C. To try a new storage way.
D. To keep their privacy safe.
9. Why might employees in cloud storage companies be distrusted by experts?
A. They sell users' passwords.
B. They have invented new tools.
C. They often let out personal information.
D. They may steal a glance at users' images.
10. What's the advantage of ESP?
A. It can provide clear images.
B. It can decrease the upload time.
C. It can classify images automatically.
D. It can encrypt data on the original platform.
11. What does paragraph 4 mainly talk about?
A. Method of decryption.
B. Image-processing technique.
C. Separate files of images.
D. Data analysisof color1 s.

Alex Wong, a junior atMarkKeppelHigh SchoolinAlhambra,California, is working hard on his application to a top college. His resume shows off his nearly straight A’s in difficult classes, experience at a summer program atStanfordUniversity, Eagle Scout project and time on the soccer team as well as the school choir. But his steady progress stopped unexpectedly this year. Aiming to open access to college-level Advanced Placement (大学预科) courses, his schoolbegan using a computer-based lottery to give out spaces. Alex got shut out of all three of the courses he requested.
The new system caused anger among families whose children failed to get into AP courses, which many consider important to develop advanced skills, improve grade-point averages and allow students to earn college credit, saving them and their families tuition dollars. Students and parents wrote to administrators to complain, circulated a petition (请愿) and launched a Facebook group for trading classes. “I’M DESPERATE! I’LL GIVE YOU FREE FOOD,” one student, Kirk Hum, posted on the 210-member AP Flea Market Facebook group.
AP classes have long been held dear by the most talented and ambitious students.But now they are seen as positive for all students who are willing to push themselves – and schools are increasingly viewing access to them as a basic educational right. But this change has brought challenges.
Miracle Vitangcol, a junior atDowntownMagnetsHigh Schoolwith average grades and test scores, is failing her AP US history class. She said she can’t handle the rapid pace and volume of material she needs to remember. But she said she intends to stick it out because the class is teaching her to manage her time, take good notes and work hard. “I’m struggling to adjust,” she said. “But I keep telling myself: ‘It’s OK. You can do it. Just push yourself’.”
Some critics worry that the open-access movement is pushing too many unprepared students into AP classes, as shown by higher exam failure rates over the last decade. They also fear that open enrollment (录取) policies are encouraging teachers to weaken courses and give out high grades to students who don’t deserve them. “While expanding access is generally a good thing, we need to make sure we’re not watering down the experience for the high achievers,” said Michael Petrilli, executive vice president of the Thomas B. Fordham Institute, a Washington-based educational policy organization.
12. The purpose of the new AP courses system at Alex Wong’s school is to ______.
A. make sure all students get access to the AP courses they desire.
B. ensure that students have a fair chance to get access to AP courses.
C. improve the academic performance of students in AP courses.
D. separate high achievers from average students through the new courses.
13. According to the article, the AP Flea Market Facebook group is a place where ______.
A. students’ parents send their complaints to school administrators.
B. students share tips about saving money for college.
C. students offer items to trade for the AP courses they need.
D. students can find support and guidance on their AP study.
14. Which of the following statements would Michael Petrilli agree with?
A. Opening AP courses to all students is a bad idea.
B. School administrators should maintain high academic standards for AP courses.
C. High schools should stop charging students for taking AP courses.
D. Access to AP courses is necessary for students applying for top American colleges.
15. The author used Miracle Vitangcol’s example to show that ______.
A. students need to remember too much in their AP courses.
B.AP courses pose a big challenge to unprepared students.
C. the secret to success in AP courses is to keep pushing yourself.
D. average students don’t deserve their places in AP courses.
