小学生10分钟应用题系列答案Those days life was so hard that I finally wished that I could just be “left alone”.
The thought of going somewhere by myself would give me so much 1 . but then I’d remember when I was alone. Not that 2 _ left me. I was alone by myself in crowded places. It was the 3 that I built around me that would not 4 the outside in or the inside out.
When I was a child, I would play this silly 5 . It was always 6 _ because a place in a corner or under a table would do. My favorite place was simply to pull a blanket over my head. I would lie there and 7 , “Right now no one in the world knows where I am!” That thought was so 8 .
If you knew me well enough this wouldn’t 9 you…I still do it at 60. It drives my dogs crazy, because they find me and start digging at the blanket until they find a way in. All three of them 10 me. That thought is so satisfying, too.
I want you to know that at times we all wish that we could be left _11 . The fact that you can be alone with yourself and enjoy it shows clearly who you are. Imagine for a 12 being locked in a room with someone you 13 . It would be torture. So, if you find peace with being with yourself, that is good.

loveTraffic jam and cities, it seems, go hand in hand. Everyone complains about being stuck in traffic; but, like the weather, no one seems to do anything about it. In particular, traffic engineers, transportation planners, and public officials responsible for transportation systems in large cities are frequently criticized for failing to solve traffic jam. But is traffic jam a sign of failure? Long queues at restaurants or theater box offices are seen as signs of success. Should transportation systems be viewed any differently? I think we should recognize that traffic jam is an unpreventable by-product of successful cities, and view the “traffic problem” in a different light.
Cities exist because they promote social interactions and economic transactions.Traffic jam occurs where there are lots of people but limited spaces. Culturally and economically successful cities have the worst traffic problems, while decaying cities don’t have much traffic. New York and Los Angeles are America’s most crowded cities. But if you want access to major brokerage houses (经纪行), you will find them easier to reach in crowded New York than in any other large cities. And if your firm needs access to post-production film editors or satellite-guidance engineers, you will reach them more quickly through the crowded freeways of LA than through less crowded roads elsewhere.
Despite traffic jam, a larger number and wider variety of social interactions and economic transactions can be made perfect in large, crowded cities than elsewhere. Seen in this sight, traffic jam is an unfortunate consequence of prosperity, not a cause of economic decline and urban decay.
So while we can consider traffic jam as increasing costs on the areas of big cities, the costs of inaccessibility (交通不便) in uncrowded places are almost certainly greater.
There is no doubt that traffic jam brings the terrible economic and environmental damage in places like Bangkok, Jakarta, and Lagos. But mobility is far higher and traffic jam levels are far lower here in the US, even in our most crowded cities. That’s why, for now, we don’t see people and capital streaming out of San Francisco and Chicago, heading for cities like California, and Illinois.

For most students, school is over and summer fun is here. Even kids who are going to summer school don't need to be cooped up indoors during these bright sunny days. Why? Thanks to technology, many kids now have the option of attending "virtual" summer schools online.
These "virtual" classes are not new. Many colleges and universities offer online courses where the students never meet; they correspond with their teachers and classmates on the web. Even some traditional schools add to daily classes with internet-based assignments and feedback.
There are a lot of benefits to online schooling, and that's why public schools have started participating in this non-traditional type of education. Instead of students riding the bus, going to class, eating lunch at school, and going home in the early afternoon, they can now log on（登录）at any time of day or night and learn. This flexible online option requires just as much work and participation as normal summer school. However, the timing is different.
Online summer school is not for all students, just like it isn’t for all adults. The student needs to be an excellent reader in order to obtain as much information as possible from the lectures. In addition, students must understand computers and be self motivated（激发）in order to complete the class successfully.
If the students meet these requirements, then online summer school has many advantages. Written lectures can be read and reread until the student understands them. The students can email each other and the teacher if they need help. Students who participate in online summer school often earn higher grades because the teachers can answer more questions without slowing down the entire class progress. And because of this new technology, summer school students can still go to the beach, travel around the world, and take family vacations!
1.Online schooling has the following advantages and benefits EXCEPT ____.
|
A．Students needn’t have as much work or participation as in traditional schools. |
|
B．Students don’t have to go to school in crowded buses. |
|
C．Students can have more time to understand the lessons. |
|
D．Teachers and students have more time to arrange their own things flexibly. |
2.What does the underlined word “option” probably mean?
|
A．chance of expressing opinion |
B．chance of expressing wishes |
|
C．right of demanding |
D．right of choosing |
3.Online summer school is not suitable for ____.
|
A．adults or children who are too old |
|
B．students who are poor in reading |
|
C．those who don’t master good computer technology |
|
D．students who can’t finish homework on their own |
4.Which of the following people is most supposed to choose online schooling?
|
A．A child in the kindergarten. |
B．A primary school student. |
|
C．A government office clerk. |
D．A child whose parents are working. |
