Tuan was a farmer in Vietnam. For decades, he had been struggling to rid his family of hunger. However, it always confused him how to expand the output of his crops. This disturbing problem led to his regretting being a farmer. He would rather have chosen another job.

Born in a pigs’ nest, Lina led a poor life in her childhood. She was looked down upon by the children of her generation. But she intended to become a doctor after she came across Lin Qiaozhi by chance, who was delivering medical courses to an audience crowding around her. Before moving off, Lin inspired her to carry on her study. With Lin’s support, Lina entered an institute and studied hard sparing no time for entertainment. Her being outspoken and modest won respect for her. Her excellent arguing skills and observation ability put others into the shade.

After a quiz last autumn, Kuang crossed the continent eastward to Toronto to visit his schoolmate, the distance measuring approximately 5,000 kilometers.

MKII, a planet billions of kilometers away, is the origin of life in many religions. Physicists have proved the theory that its gentle climate and the pull of its gravity are similar to the earth’s. And astronomers have found that oxygen atoms and carbon dioxide, which are fundamental to life, exist in its atmosphere through satellites. Cheered up by this news, biologists, in their turn, began to do some research to remove people’spuzzles—Now that there are some suitable conditions, does life really exist on this globe? Do they multiply by laying eggs or giving birth to babies?

This novel was about an unbelievable but genuine adventure. Its author was a black businessman who was brought up in America. In 1956, he visited Africa, his birthplace. One day, when he was wandering on the pavement near the bay enjoying the sea scenes, he lost his money and passport that he kept in an envelope. So he went to the embassy to seek help, but the ambassador with rude manners didn’t permit his staff to help though he bowed to him. Staring at his impatient face, he understood that it was the fault of his skin colour that accounted for their refection. So he decided to take a chance to sail on a small boat home.

Wang Peng earned his living by running a barbecue restaurant, which served delicious bacon, fried chicken breast and mutton roasted with pepper and garlic. But his food and discount attracted fewer and fewer customers. Finally, he was in debt. Yong Hui’s slimming restaurant served fresh peas, carrots, eggplants, andraw cucumbers with vinegar. As the hostess, she said fibres benefited customers' digestion the most. In order not to let Yong Hui get away with telling lies, Wang Peng spied on Yong Hui despite her glare. But he was surprised that she was losing her customers, too.

The Agricultural Feast takes place after the Independence Day. It is not a worldwide celebration. Only Christians in Mexico look forward to its arrival for its religious origin:

I was very sensitive to music. Just dipping into the music books briefly, I could sing or play well. To be honest, I always dreamt of becoming a famous folk actor. I was so confident that I never decreased my devotion.

Dinosaurs died out because of an unexpected incident. But wildlife today disappears or is in danger just because humans do harm to it. For example, tigers are hunted for fur to make carpets so that they can only live in secure reserves; grassland is destroyed without mercy so that dust storms come into being affecting distant cities.

The goal of early calculating machines was to simplify difficult sums. But with the help of new technology, electronic chips replaced tubes and a revolution of artificial intelligence has arisen. From then on, the appearance of computers totally changed our lives. They can not only download information from the net when connected by the network or mobile phone signals, but also solve different types of logical problems. With operators as their coaches, they can even control rockets to explore the moon and instruct androids with the human race’s characters to mop floors and watch over your naughty niece. Anyhow, computers are so helpful that they do bring happiness.

Swifter, Higher and Stronger stands for the spirit of the Olympics. But fairness is the basis of this motto. Only when you win fairly will you and your homeland deserve the great glory. But nowadays, unlike the ancient honest slave competitors, some hopeless athletes who can’t bear the pain of training cheat when taking part in games.

A wooden vase from the Ming Dynasty at the entrance of the reception hall amazed everyone. The artists designed it in a rare style and selected valuable jewels to decorate it. People thought highly of its fancy colour of honey and the beautiful paintings on it.

Yes, there is a connection between "direct" and "directive," both in terms of their etymology (the study of the origin of words and how their meanings have evolved) and their usage in language. Both words are derived from the Latin word "directus," which means "straight" or "to straighten." From this root, the meaning extends metaphorically to concepts of guidance, control, and management. Let's explore each word to understand their connection and distinctions:

computed区别于methods的两个核心

• computed是属性访问，而methods是函数调用
• computed带有缓存功能，而methods不是

Java RMI(Remote Method Invocation)是一种强大的技术，它允许对象调用运行在另一个 Java 虚拟机（JVM）中的对象的方法。RMI 为创建分布式应用程序提供了一个简单直接的模型，使开发人员能够构建和部署可轻松跨网络（包括互联网）运行的系统。它是 Java SE（标准版）平台的一部分。

The State Pattern is a behavioral design pattern that allows an object to alter(改变) its behavior when its internal(内部) state changes. This pattern is used to encapsulate(封装) varying(变化) behavior for the same routine(例行程序) based on an object's state object. It's essentially(本质上) a way to model state transitions(过渡) in an object-oriented(面向对象) way.

The Iterator Pattern is a design pattern used in software development to provide a way to access the elements of an aggregate object sequentially without exposing its underlying representation. It falls under the category of behavioral patterns, as it is used to manage algorithms, relationships, and responsibilities between objects.
迭代器模式（Iterator Pattern）是软件开发中使用的一种设计模式，它提供了一种在不暴露底层表示的情况下按顺序访问聚合对象元素的方法。它属于行为模式的范畴，因为它用于管理对象之间的算法、关系和责任。

The Template Method Pattern is a behavioral design pattern that defines the program skeleton of an algorithm in a method, deferring some steps to subclasses. It lets one or more steps of the algorithm vary by letting subclasses redefine certain steps of the algorithm without changing the algorithm's structure. This pattern is a fundamental technique in software engineering for reusing code and is particularly useful in situations where the overall structure of an operation is fixed, but the individual steps are flexible and subject to change.
模板方法模式（Template Method Pattern）是一种行为设计模式，它在一个方法中定义了算法的程序骨架，将某些步骤推迟到子类中。它允许子类在不改变算法结构的情况下重新定义算法的某些步骤，从而使算法的一个或多个步骤发生变化。这种模式是软件工程中重用代码的基本技术，尤其适用于操作的整体结构固定，但各个步骤灵活多变的情况。

Simple Factory Example

// Simple Factory
class AnimalFactory {
    public Animal getAnimal(String type) {
        if ("Dog".equalsIgnoreCase(type)) {
            return new Dog();
        } else if ("Cat".equalsIgnoreCase(type)) {
            return new Cat();
        }
        return null;
    }
}

interface Animal {
    void speak();
}

class Dog implements Animal {
    public void speak() {
        System.out.println("Woof");
    }
}

class Cat implements Animal {
    public void speak() {
        System.out.println("Meow");
    }
}

// Client code
public class Main {
    public static void main(String[] args) {
        AnimalFactory factory = new AnimalFactory();
        Animal myDog = factory.getAnimal("Dog");
        myDog.speak(); // Outputs: Woof
    }
}

The Command Pattern is a behavioral design pattern that turns a request into a stand-alone object. This object contains all information about the request. This transformation allows you to parameterize methods with different requests, delay or queue a request's execution, and support undoable operations. It's a part of the larger family of design patterns often utilized in software development for organizing code in a way that is both flexible and scalable.
命令模式是一种行为设计模式，它将请求转化为一个独立的对象。该对象包含请求的所有信息。通过这种转换，您可以为具有不同请求的方法设置参数，延迟或排队执行请求，并支持可撤消(undo)的操作。它是软件开发中常用的大型设计模式系列的一部分，用于以灵活和可扩展的方式组织代码。
