7．People often have the impression that Chinese characters are extremely difficult to learn．In fact，if you were to try to learn how to write Chinese characters，you would find that they are not nearly as difficult as you may have imagined．And they certainly qualify as forming one of the most attractive，beautiful，logical（合乎逻辑的），and scientifically constructed（构造）writing systems in the world．Each stroke（笔画）has its own special significance．If you are familiar with the rules of Chinese characters，you will find it very easy to remember even the most complicated looking character，and never miss a stroke．
The earliest known examples of Chinese written characters in their developed form are carved into tortoise shells and ox bones．The majority of these characters are pictographs．Archaeologists of various countries have learned that most early writing systems went through a pictographic stage，as did the Egyptian hieroglyphics．Most writing systems，however，eventually developed a phonetic（表示语音的）alphabet to represent the sounds of spoken language rather than visual images observed in the physical world．
One notable feature of Chinese characters is the"radical．""Radical"in English means"root"．For example，the characters yu"language，"shuo"talk，"i"discuss，""opinion，"and lun"discuss"all share the yen radical，which means"language，"and gives the reader a clue to the meaning of the character as a whole．The characters hsiu"rotten，"shan"cedar，""t'ao"peach，"and lin"forest，"all contain the mu"wood"or"tree"radical，indicating one of their shared key characteristics．If you know the radical of a character，you can usually get a general idea of the meaning of the character it is a part of．Although there is a theoretical total of almost 50，000written Chinese characters，only about 5，000of these are frequently used； and the total number of radicals is only 214．So learning to read and write Chinese is not nearly so formidable a task as it may at first seem．
33．According to the author，Chinese characters areB．
A．extremely difficult to learn
B．scientifically constructed
C．difficult to remember
D．as difficult as you may have imagined
34．Which of the following statements is TRUE according to the passage？A
A．There are rules in forming the Chinese characters．
B．Some strokes are more important than others．
C．All the Chinese characters are pictographs．
D．Some writing systems eventually developed a phonetic alphabet．
35．The passage is mainly aboutC．
A．pictographs
B．the strokes of the Chinese characters
C．the Chinese writing system
D．the radical of the Chinese characters．

4．Knuckle-popping（指关节砰砰响）
Do you slurp（咕噜）soup？Do you pop bubble gum？If you do，your habits won't help you win friends-but they're fun．But how about knuckle-popping？Not you does this hobby give people around you the"willies（[俚]神经紧张），"but cracking knuckles can lead to monster knuckles（异乎寻常的响声），and maybe-to arthritis （关节炎）．
At least，most people think knuckle-popping is bad．Well，there's no doubt that the people who have to listen to knuckles being snapped（啪地一声折断）can't stand the sound．But how bad is it for the knuckle-popper？
A doctor has looked into this indoor sport．He says it's not harmful．Dr．Robert L．Swezey found that his son was cracking his knuckles．And the kid's grandmother thought it was terrible．So Dr．Swezey went to a home for the aged．He studied the knuckles of old people there．Only one out of fifteen old people who said they cracked their knuckles all their lives had something wrong with their finger joints．Also，five out of twelve women who never cracked their knuckles had trouble with their joints．So if you want to go on popping your knuckles，Dr．Swezey says if OK，even if his son's grandma still doesn't like it．
28．People who hear others cracking their knucklesA．
A．are bothered．
B．don't notice the sound
C．start to crack their own knuckles．
D．feel it's as had as slurping soup．
29．When Dr．Swezey went to the old-age-home，what did he find out about old people who had cracked their knuckles？C
A．Only one old people had something wrong with their finger joins．
B．Only old women had cracked their knuckles．
C．About 6.7percent of the old people had something wrong with their finger joints．
D．The old people were all well．
30．Which of the following is right？D
A．Slurping soup and popping bubble gum are food habits．
B．Cracking knuckles will lead to arthritis．
C．No one likes cracking his knuckles．
D．Some women who didn't crack their knuckles had something wrong with their finger joints．
31．If you pop your knuckles，Dr．Swezey thinks you might as wellA．
A．go on doing it．
B．stop at once．
C．avoid people who do it．
D．not do it around your friends．

11．I could tell from your expressionthat you were lying．

Computers have beaten human world champions at chess and, earlier this year, the board game Go. So far, though, they have struggled at the card table. So we challenged one AI to a game.

Why is poker(扑克)so difficult? Chess and Go are “information complete” games where all players can see all the relevant information. In poker, other players’ cards are hidden, making it an “information incomplete” game. Players have to guess opponents’ hands from their actions----tricky for computers. Poker has become a new benchmark for AI research. Solving poker could lead to many breakthroughs, from cyber security to driverless cars.

Scientists believe it is only a matter of time before AI once again vanquishes humans, hence our human-machine match comes up in a game of Texas Hold’s Em Limit Poker. The AI was developed by Johannes Heinrich, researcher studying machine learning at UCL. It combines two techniques: neural(神经的)networks and reinforcement learning(强化学习).

Neural networks, to some degree, copy the structure of human brains: their processors are highly interconnected and work at the same time to solve problems. They are good at spotting patterns in huge amounts of data. Reinforcement learning is when a machine, given a task, carries it out, learning from mistakes it makes. In this case, it means playing poker against itself billions of times to get better.

Mr Heinrich told Sky News: “Today we are presenting a new procedure that has learned in a different way, more similar to how humans learn. In particular, it is able to learn abstract patterns, represented by its neural network, which allow it to deal with new and unseen situations.”

After two hours of quite defensive play, from the computer at least, we called it a draw.

1.Why can’t the computer beat humans at the poker game?

A. Because humans are cleverer than the computer

B. Because humans practice playing the poker game every day

C. Because the computer can’t know the other players’ cards completely

D. Because the computer can’t learn the regular rules of the poker game

2.What does the underlined word “vanquishes” in Paragraph 3 mean?

A. Leaves B. Defeats C. Cheats D. Serves

3.What do we know about the reinforcement learning of AI?

A. It solves problems correctly every time

B. It is the same as the learning of humans

C. It learns from the mistakes appearing in a task

D. It is more developed than the studying ways of humans

4.What can be inferred from the text?

A. The new procedure of AI has some features of humans

B. Computers are stronger than humans in every aspect

C. Humans will beat computers at playing poker forever

D. Scientists feel unhappy about the result of the poker game

With the development of people’s living condition, more and more people possess their own cars. Some of us think it is good to own a car. For instance, it’s convenient, fast and comfortable means of transportation. Moreover, it shows that people are becoming richer and the country is much more stronger. It also made relative businesses and industries develop faster.

However, others have different opinions, thinking that cars give up waste gasses and pollute the environment around. Too much cars will have some bad effects, such as more accidents and crowdedness. Besides, lack parking lots is another big problem.

As far as I’m concerned, we ought to think careful before buying cars. As if we have cars, we may use it less.
