Congrats !

Just got a call from British Countil, saying  the speaking remarking result has been changed from 5.5 to 6 ...

 

Hahah, Great!

 

Just to memorize this moment ^_^

This page is a simplified implementation of the game [tetris](https://www.freetetris.org/) * This page exists on route `/tetro` and contains the header and footer from `1.2.1`. (0.5) * The page will consist of a 10 (wide) by 12 (high) grid/board of cells that fills the main body, except it has a `20px` `margin` on the top, left, and right, and a `100px` margin on the bottom. (3) * Cells are distributed evenly in this space (and therefore will often not be square). Each cell has a transparent background with a `1px` border coloured `#333333` that is `solid`. (2) * The gameplay process is as follows: * A) The game becomes active when the user clicks on the board, then step B happens. (0.5) * B) one of the following shape objects appears in the top left of the screen: `2 x 2 block`, a `2 (high) x 1 (wide) block`, or a `1 x 1 block`, with the top left cell of the block appearing in the top left cell of the board. (3) * C) After the block appears on the screen, every 1 second, the block moves 1 cell vertically further down the screen. (1) * D) During the gameplay, when the board is `active` (i.e. has been clicked on), the left and right arrow keys on the board will move the block one cell to the left or right respectively, if it is able to. (2) * E) If a block cannot move any further down the board (i.e. one of the cells it would have moved to is occupied by another block, or the block is already at the bottom row of the board), the block becomes locked in place in it's position and another block appears on the screen as per (B). (5) * Every time a new block is locked in place, if there are any rows that are filled with cells, all of the cells in that row turn green `rgb(0,255,0)`. (2) * Once five rows have been coloured green, the game stops as the player has won and an `alert` appears saying `Congrats!` that when closed the game restarts. (1) * If, when a block becomes locked in place, it occupies a cell that is higher than one of the first 8 rows, the player loses with an `alert` saying `Failed`. Once closed the game restarts. (1) * A reset button exists below the grid of cells that when clicked, restarts the game (i.e. go to step A, waiting for the board to be active). (1)这个题目怎么写,用Tetro.jsx和App.css
