Parents who feel disappointed at their teenagers’ failure to pay attention in class, and inability to sit quietly long enough to finish homework or plan ahead, should take solace. Their children are not being lazy or careless, according to new research.
The research has found that teenagers’ brains continue developing far longer into adulthood than we used to think. Teens may look like young adults but their brain structure is similar to that of much younger children.
“It is not always easy for teens to pay attention in class without letting their minds wander, or to ignore distractions from their younger brothers or sisters when trying to solve a maths problem,” said Dr Iroise Dumon-theil. “But it’s not the fault of teenagers that they can’t pay attention and are easily distracted. It’s to do with the structure of their brains. Teens simply can’t think as well as an adult.”
The research showed that the brain of a teenager works less effectively than that of an adult. “We knew that the front of the brain of teens functioned in a chaotic (混乱的) way but we didn’ t realize it continued until the late 20s or early 30s,” said Dr Sarah-Jayne Blakemore, who led the research.
Chaotic thought patterns are a result of teenagers’ brains containing too much grey matter — the cell bodies and connections which carry messages within the brain. As we age, the amount of grey matter in our brain reduces.
“What our research has shown is that there is simply too much going on in the brains of teens,” said Blakemore. “The result is that their brain energy and resources are wasted and their decision-making process is badly influenced. Adults, on the other hand, have less grey matter. This means that the brain works far more effectively.”The underlined word “solace” in Paragraph 1 may mean _____.
| A． notice | B．medicine | C．comfort | D．action |
When making decisions, _____.
| A．teens’ brains continue to do much needless work |
| B．the grey matter in young children’s front brain becomes active |
| C．people are not likely to be distracted until their late 30s |
| D．adults are more independent than teens |
What is the effect of having too much grey matter?
| A．It makes us always feel disappointed. |
| B．It makes us more intelligent. |
| C．It had a bad effect on the growth of teens. |
| D．It had a bad effect on decision-making. |
What’s the text mainly about?
| A．Teens have different brains from those of children. |
| B．Adults work more effectively than teens. |
| C．Grey matter makes teens unable to pay attention. |
| D．Brain energy is wasted in the brain’s activity. |
For many years，machines have been doing work that people once did，including some dit- ficutt jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings： the restaurant industry.
Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from South Korea and its robot，called DRC-Hubo，won the first place in the competition. The second and third place winners were from the United States. The robots were required to drive a vehicle，climb up steps and do mechanical work. Such activities are easy for humans to perform，but more difficult for machines. Not all of the competitor were successful. The failures showed how difficult it is to design effective walking
machines.
Akihiro Suzuki works at Yaskawa Electric，a company that develops robots. He says robots cannot do everything a human can，but they are able to work without becoming tired. He says robots cannot taste food，change heating levels or seasonings to get the best flavor (风味）.But he says if a food can be easily prepared，a robot can repeat the same movement to reproduce the same meal.
One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery showed its sushi (寿司）maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all over the world now eat sushi，but there are not enough skilled workers to prepare it. He says his machine can help anyone make sushi.
In Paragraph 1，the author tells us .
| A．robots just do difficult jobs |
| B．robots are sometimes dangerous |
| C．robots are widely used in our life |
| D．robots are gradually replacing humans |
Why did some teams fail at the DARPA Robotic Challenge Finals?
| A．Their robots cannot be applied at home. |
| B．Preparing food is really difficult for robots. |
| C．Their robots can just repeat the same movement. |
| D．They failed to design effective walking robots. |
We can infer from the last paragraph that .
| A．Japanese men are lazy |
| B．robots are popular in Japan |
| C．Japan has advanced high technology |
| D．robots usually take the job of making sushi in Japan |

Reading is a great way to improve your English. You'll learn new words, revise previously-taught structures and absorb thousands of useful expressions and phrases... without any effort. By reading, you are receiving valuable language input. And this is how you learn! Remember, language learning is a combination of input + practice. As you're reading, you're taking in language naturally, and you're seeing how it all fits together. This is crucial to your learning.
The great thing about reading is that learning takes place subconsciously. There are no exercises to do, no grammar rules to learn, no tasks to complete... it's all natural. The language flows in through your eyes, and gets recorded in your brain. What could be easier?
The key to effective reading is to read things that you want to read. There are millions of books, magazines and websites out there. You couldn't possibly read them all. So, the important thing is to find things that you like reading. Then, you'll be motivated to read. And then the reading won't be difficult. It'll be easy! And then you'll learn. It's simple.
Remember: read what you want to read. What you like reading. What motivates and inspires you. But where can you start? Well, you could read a book that you've already read in your own language. Simply find a translated version of a book that you have read and enjoyed. This will make processing the content in the target language much easier as you’ll already know what the book is about! You could also read the news. This is great as you can read the news in your own language first, then in English. You'll see that it won't be too difficult as you'll be familiar with the topics and stories. Magazines are also great. Find one that covers a topic you're interested in: business, clothing, guns, horses, houses, housekeeping, stocks and shares, sports, computers, electronics, designing, cooking... you name it, they'll have it. If not, look for information on the internet. There are also websites for every topic under the sun! Why not join a forum? They're a great source of English input as the language is often written in a simple, spoken style. Go to Google Groups, which has discussion groups based on common interests. Just type in the topic that interests you and join the chat.
Finally, how you read is also important. The best thing is to read without using a dictionary. Let the words flow over you. Just skip the parts you don't understand. If you make your reading feel too much like work, it'll stop being fun. Of course, you could make a note of any new words and phrases that you like or see repeated frequently, but try not to break your concentration too much. Also, set yourself mini-objectives. For example, if you're reading a novel, read 20 pages a day. Very soon, you'll have been exposed to thousands of useful phrases and words. Have fun reading! You'll learn so much!The underlined word “crucial” in the first paragraph is closest in meaning to ________.

Dad was lying in the hospital weakly, but his smile was as sure as ever . It was another attack of lung illness. My husband and I stayed with him for the weekend but had to return to our jobs on Monday. Local relatives would help Dad get home from hospital and look after him. But I longed to be able to let him know that we cared about him too, even when we weren't with him.
Then I remembered a family tradition when our children were small. When leaving our grandparents’ home after a visit, each child would write a love note to their grandparents. We hid notes in a box, under a hairbrush or next to the phone or even in the microwave oven. For days, our grandparents would smile as they discovered these reminders of our love.
So as I tidied Dad’s kitchen and made up a bed for him downstairs in the living room, I wrote some notes. Some were practical, "Dad, I put the food in the fridge so it wouldn't spoil". Some expressed my love, “Dad, I hope you will sleep well in your new bed.” Most notes were downstairs where he would stay for several weeks until he recovered strength, but one note I hid upstairs under his pillow, "Dad, if you have found this note, you must be feeling better. We are so glad!"
Just like his medicine strengthened him physically, these "emotional vitamins" would improve his spiritual health. Several weeks later, in one of our regular phone calls, I asked Dad how he was doing. He said, "Pretty good. I just found your note under my pillow upstairs!"
