On April 23.2019，a series of events to celebrate
the （1） anniversary of the Chinese People's Liberation Army（PLA）Nay（中国人民海军）was held in Qingdao．
Destroyers（驱逐舰） sailed in the sea， submarines（潜艇） slid under the surface and fighter jets flew across the sky． It wasn't a scene from a war movie， indeed， it was a real grand naval parade．
As a large country （2） more than 18，000 kilometers of coastline， China needs a strong navy． This was a hard lesson（3） by history． According to Xinhua， from the 1850s until 1949．foreign forces used the sea to make about 470 invasions of China． Therefore， the PLA Navy has become a key line of the nation's defense．
As President Xi Jinping said， the oceans are of great significance as they sustain life and connect the world． "The blue planet that humans inhabit is not divided into islands by the oceans．（4） is connected by the oceans to form a community with a shared future， where people of all countries share weal and woe，"said Xi during his （5） at the event．

In 30 years from now，what will we eat？ Will the food still be the same as it is now？
The United Nations says that there will be over 9 billion people in the world by 2050． Our food needs will grow by 70%． What we eat now may not be enough for humans in the future． That is to say， we 'll have to turn to something else． But what else can we eat？ Here are a few possible choices．
Veggie（Vegetable）meat
A new kind of hamburger is now popular in the US． It looks the same as any other hamburger．，and so is the taste． But it's actually a "beef" burger made out of plants． The company behind the burger，Impossible Foods， uses peas and potatoes to make the"beef"． They take coloring， protein（蛋白质） and fats from these plants and mix them together．
Making meat out of plants uses less water and land than raising animals for meat．It also creates fewer greenhouse gases， Some food companies are making chicken，pork and other meat out of plants， too﹣ follow the same steps as making the " beef"．
Insects
Insects make up little space and don't make much waste． They also have more protein than beef，chicken and pork．This makes insects another possible food of the future．
It's common for people in some places to eat whole insects， But most people probably won 't want to see the insects they eat． So in the future． people will first turn insects used for food into powder（粉末）． Then they can use the powder to make other foods like chips， protein bars， biscuits and so on．
Algae
The BBC says algae farming could become the world's biggest farming industry in the future． They point out that algae is cheap and grows very quickly． Also， it's very nutritious（有营养的）． It has much more protein and oil than many other plants．
Besides eating algae as a dish on its own． people may also use algae oil and algae butter in the future， Some algae has a strong taste． The UK scientists are trying to use algae to take the place of salt．
| Reason Traditional food may not（1） of people in the future because of the rising population． |
Result predictions； Humans will have enough food． Future food is good for both （2）

bad British consider fun hope pleasure power they total understand we win
Is it true that we British people have a different sense of humor from people in other countries？ Let's have a look at what we laugh at in（1） ．
To us British people，（2） and important people often cause laughter． It's not just politicians（政客） who make us laugh， but anyone whose job is to tell other people what to do and who takes（3） too seriously．
We laugh at the power， but also， pitifully， at anyone who is treated （4） ， We know they cannot win，but if they do win sometimes，it's even（5） ．Our clowns（小丑）are often silly people doing silly things，while in America，they are often clever people doing clever things﹣and （6） at last．
The fact that we laugh when other people might feel （7） is one of the strangest things to learn about British humor． We do have a strong sense of irony （反讽）． After some terrible experience，we might say， "Not very（8） ． " And we might say in the middle of a typhoon，" It's a bit windy today．" Or"There is a tiny problem，"when something has gone（9） wrong． We don't like to express strong feelings， but just "keep calm and carry on"．
Another thing that can make it difficult （10） British humor is that we don't always laugh or even smile when we say something funny． We often keep a straight face or use an unsmiling expression when we're making a joke．
Do you think the British sense of humor is special？

Peter：I think so．What's more，to become（6） ，people should still exercise more．Doing sports daily will make people（7） in good condition．
Dave：These days，people have so much（8） ，because they're quite busy studying and working．Many people go to bed very late，even when they have to go to school or to work early the next morning．
Peter：That's true．They may find nothing（9） in their bodies and feel least uncomfortable at first．But if such（10） lasts long，people will finally get sick．
Dave：Doing sports is a good way to get relaxed． It will do good to people's health．
