Going to the zoo is very popular. Every year over 134 million visitors go to zoos to enjoy watching and learning about the animals. Zoos are the only places that most people will ever meet an elephant, a tiger or other animals that are in danger. {#blank#}1{#/blank#}. They help us to enjoy different kinds of animals as well as make us think more about nature(自然).

   Zoos are also important to animals. In order to make more space(空间), food, and other things for ourselves, we leave less and less room for animals. {#blank#}2{#/blank#}. If there were no zoos, more animals in the world would have gone extinct(濒临灭绝). {#blank#}3{#/blank#}. Some people think that animals should not be kept by people for any reason(原因). If they become extinct, then that's the way it should be. {#blank#}4{#/blank#}. We should do everything we can to protect them(保护它们).
{#blank#}5{#/blank#} What's the best title of this passage?

    A crow(乌鸦) is about twenty inches (英寸) long and black all over. Crows are dirty birds because they live on bad food. Crows eat a lot of waste food. In this way they are more useful to us than any birds. They clean up the dirty things in our streets. Crows are always hungry. They look for food all day, and in the evening you can see them in large numbers flying back to their nests(巢) in the trees. They sleep there at night.

    Crows are much noisier than other birds. Very often a large number of crows will get together on one house and talk. Sometimes they talk together, and sometimes they do it by turns(轮流) like human beings(人类). It is easy to tell(判断) from crow's sound if they are pleased or angry. Perhaps crows talk a lot because they are friendly birds. A pair of crows will live together all their lives, and if one of them dies, the other one becomes very sad and quiet for the rest of its life and some time later it dies too.

Let's Enjoy a Movie!

I've never imagined the movie is so interesting. There are 64 kinds of animals in it. After watching the movie，I learned more about animals. I would recommend this movie to those animal lovers.

I have seen many cartoons of this kind，but the plots（情节） are very funny and I love the sweet voice in it. My brother and I just couldn't help laughing from the beginning to the end.

—David

This movie is so well made. I went to see it with my 5﹣year﹣old son last Sunday afternoon. I love the beautiful music while my son loves the rabbit police officer，Judy very much.

Our lives would not be the same without bees. Bees help plants grow. Many of these plants provide us with food. What would happen if there were no bees? Some fruits and vegetables that we enjoy could not grow. Bees are wonderful creatures*.

But now the number of bees is getting lower and lower. Scientists worry that bees may die off. How can we solve it? One answer is to make our gardens friendly to bees.

Making our gardens bee- friendly can increase the number of bees. Planting a bee garden is a great idea. These gardens provide bees with nectar*. A successful bee garden would have flowers from spring to fall. The garden would have all kinds of plants that are closely grouped together.

Many people believe that all bees live in hives. In fact, some bees dig into the ground. There they build nests and lay eggs. People lay wood pieces or other things on the ground. Bees can not dig nests when these materials cover the ground. Here is another good way to help bees. When you are working outside, leave loose dirt* in flower beds and gardens.

Some bees' nests are in old pieces of wood while others' in holes, in buildings or in trees. Gardens can provide spaces like these for bees. Trees or walls that stop wind are a good idea. And cool areas also can help bees get away from the hot sun. Bee gardens also provide bees with water. Bees need water just like people do

Making a garden friendly for bees is far from a useless task. The results are worth* the efforts*.  A bee- friendly garden is beautiful and colorful. Most importantly, it helps to keep bees healthy and happy.

 When you look into the mirror, you may wonder whether it is possible for us to have a twin self who can do lots of challenging things for us, like the difficult project to be finished ahead. Now with the invention of digital twins, it seems possible.

A digital twin is a copy of things like the products or persons in the online forms. Like humans,    a digital twin can also develop itself as long as they are fed with enough data(数据).

 In 1970, when Apollo 13 was carrying out its task in space, something went wrong with the spaceship, leaving astronauts stranded(困住)200,000 miles from Earth, NASA engineers used spacecraft data to recreate the conditions of the broken part of the spacecraft. This method allowed them to develop solutions that finally brought the astronauts safely home. This event is widely thought as the birth of digital twins. Since then, this technology has been used in many fields, including business, medicine, and more recently, human modelling.

 One of the most fantastic uses of digital twins is in health care. Professor Declan O' Regan, an    AI expert, shows the new method can help doctors treat certain illness easily and quickly, and it can even help doctors to find ways to stop some kind of illness before it is too late.

 Another successful example is to use the digital twin to change the sports science to some degree. Compared with the past when the coaches needed to set up a program to help train the sportspersons, they now use the data to build the digital twin to help the athletes to improve their skills and avoid accidents in sports.

 Not everything about the digital twin is good. It is clear that the new technology will influence us a lot, but what direction it will take in the future remains to be seen. There are some doubts over it, as it will result in problems related to ethical(道德的) consideration.
