If you want to become a fluent English speaker you should take some advice: There are four skills in learning English. They are reading, listening, speaking, and writing. The most important thing you must remember is that if you want to improve your speaking and writing skills you should first master the skills of reading and listening. Read as much as you can. But your reading must be active. It means that you must think about the meaning of the sentence, the meanings of the unfamiliar words, etc. There is no need for you to pay much attention to grammars or try to understand all the unfamiliar words you _ , but the fact that you see them for the first time and recognize them whenever you see them, for example in other passages or books, is enough. It would be better to prepare yourself a notebook so you can write down the important words or sentences in it. As for listening, there are two choices: besides reading, you can listen every day for about 30 minutes. You can only pay attention to your reading and become skillful at your reading, then you can catch up on your listening. Since you have lots of inputs in your mind, you can easily guess what the speaker is going to say. This never means that you should not practice listening. For listening you can listen to cartoons or some movies that are specially made for children. Their languages are easy. Or if you are good at listening you can listen to VOA or BBC programs every day. Again the thing to remember is being active in listening and preferably taking some notes. If you follow these pieces of advice, your speaking and writing will improve automatically, and you can be sure that with a little effort they will become perfect.

According to the author, which should you improve first among the four skills?

Ex Input:
Selenocysteine, a selenium-containing analog of cysteine, is found in the prokaryotic and eukaryotic kingdoms in active sites of enzymes involved in oxidation-reduction reactions. Its biosynthesis and cotranslational insertion into selenoproteins is performed by an outstanding mechanism, implying the participation of several gene products. The tRNA(Sec) is one of these. In eukaryotes, its transcription mode by RNA polymerase III differs from that of classical tRNA genes, both at the level of the promoter elements and transcription factors involved. In addition, enhanced transcription is afforded by a newly characterized zinc finger activator. Not only transcription of the gene, but also the tRNA(Sec) itself is atypical since its 2D and 3D structures exhibit features which set it apart from classical tRNAs. Decoding of eukaryotic selenocysteine UGA codons requires a stem-loop structure in the 3'UTR of mRNAs, the selenocysteine insertion sequence (SECIS) element. Structure probing and sequence comparisons led us to propose a 2D structure model for the SECIS element, containing a novel RNA motif composed of four consecutive non-Watson-Crick base-pairs. A 3D model, rationalizing the accessibility data, was elaborated by computer modeling. It yields indicative or suggestive evidence for the role that could play some conserved residues and/or structural features in SECIS function. These might act as signals for interaction with SBP, the SECIS binding protein that we have characterized.

"Legend tells of a legendary warrior whose kung fu skills were the stuff of legend..." A mysterious panda donning a flowing cape and sedge hat walks through the Chinese landscape. Reputed to be a grand master of kung fu, he enters a tavern where he is immediately attacked by the local ruffians. However, they are no match for his skill and even the legendary kung fu masters, the Furious Five, bow down to the panda's skill, requesting to hang out with him and fight alongside him as......Po the giant panda (Jack Black) wakes up from his dream in his room. His goose father, Mr. Ping (James Hong) calls to him from the noodle restaurant below to help serve tables. Po admires his Furious Five action figures before going downstairs. An extreme fan of Kung Fu, Po dreams of one day becoming a master worthy of fighting alongside the Five but his girth and clumsiness makes this dream simply a dream and his kung fu talents reside only within his knowledge of moves and artifacts. He is hesitant to express his desires to his dad who is more interested in running his restaurant and advertising his famous 'secret ingredient soup'.Master Shifu (Dustin Hoffman), a red panda who resides at the Jade Palace temple, practices kung fu in the courtyard with his students, the Furious Five; Tigress (Angelina Jolie), Crane (David Cross), Monkey (Jackie Chan), Viper (Lucy Liu), and Mantis (Seth Rogen), before he is summoned to see tortoise Grand Master Oogway (Randall Duk Kim). Fearing something is wrong, Shifu rushes to find him meditating in the grand hall. Oogway doesn't deny bad news but calmly tells Shifu he's predicted that the snow leopard warrior Tai Lung (Ian McShane) will escape prison and return to the Valley of Peace to wreak destruction once again. Intent on never letting this happen, Shifu sends his goose messenger, Zeng (Dan Fogler), to fly to Chor-Gom Prison to ensure that security is increased. Oogway then proclaims that it is time to choose the Dragon Warrior; a master of great skill who will be granted the secrets of the universe by reading the Dragon Scroll, kept delicately out of reach on the temple ceiling. Assuming that one of the Furious Five will be chosen, Shifu prepares a competition to determine which one will qualify.Flyers for the competition are spread throughout town and the villagers flock to the temple. Excited to have the opportunity to see his idols in person, Po follows with his noodle cart in tow but struggles on the long staircase to the temple. He is the last to arrive at the gates and finds that they've shut him out. In a desperate bid to see the competition before it's over, Po fashions fireworks to his cart and blasts himself high into the air, only to come crashing down in the arena just as Oogway is preparing to choose out of the Five. Po opens his eyes to see Oogway's finger pointed right at him and is shocked, along with everyone else, when he is proclaimed to be the Dragon Warrior. Oogway's decision is final, despite Shifu's protests, and Po is carried (unsuccessfully) into the temple leaving Tigress greatly disappointed since it seemed Oogway would have chosen her if Po hadn't arrived.Inside the temple, Po examines, with awe, the many weaponry and valuable artifacts before Shifu approaches him and berates him for his obvious lack of skill. He deflates Po's excitement by grabbing his finger in what Po recognizes as the Wuxi Finger Hold, reputed to be extremely powerful. Shifu promises that Po will regret ever being chosen before taking him to the Fives training room where Po is promptly put to the test. Nervous, but excited to try some kung fu moves, Po accepts the challenge but is hurtled, flung, and beaten down to a now-existing Level 0.On the way to the dormitories, Po overhears the Five poke fun at his incompetence. He has an awkward conversation with Crane, opening up to his own doubts of being the Dragon Warrior. Tigress assures his doubts, calling him a disgrace to kung fu and tells
