一、时态的类别
时态从时间上可划分为四大类:现在时、过去时、将来时和过去将来时。从状态上又可分为:一般式、 进行式、完成式和完成进行式。英语的动词合起来,总共有16种时态。 同学们在七年级上学期已经学习了一般现在时、一般将来时和一般过去时。你们是否还记得其动词的变化呢 请你写出work一词的时态变化:

二、基础用法梳理
各种形式:
请以work为例填写其在现在进行时中的各种变化形式:
肯定式 否定式
单数 I　　　　　　　　. You 　　　　　　　　. He 　　　　　　　　. I　　　　　　　　.
You 　　　　　　　　.
He 　　　　　　　　.
复数 We 　　　　　　　　. We 　　　　　　　　.
疑问形式和回答
人称 疑问形式 回答
第一人称 　　　 I　　　　 Yes, 　　　　　　　.
No, 　　　　　　　.
第二人称 　　　 you　　　　 Yes, 　　　　　　　.
No, 　　　　　　　.
第三人称 　　　 he　　　　 Yes, 　　　　　　　.
No, 　　　　　　　.
答案:略
用法与意义:
请阅读下面关于现在进行时的用法,然后整理成思维导图。
1.当我们强调动作此时此刻正在发生,我们可以用现在进行时。比如:
Don’t make any noise! The baby is sleeping.
2.我们还可以用现在进行时表示当前一段时间内的活动或现阶段正在进行的动作。比如:We are learning to play the piano these days.这种用法也可以表示这种情况是暂时的。比如:She is spending the summer in Europe.
3.现在进行时还可用来表示变化、趋势、发展和进展。比如:His handwriting is improving.The village is changing.
4.某些动词的进行时态可表示将来的动作。比如:A few foreigners are coming to visit our school this afternoon.现在进行时表示将来这种用法常指“意图”“安排”或“打算”,这种表述比较生动,给人一种期待感。能这样用的动词有:arrive, come, do, get, go, have, leave, meet, play, return等。
5.使用现在进行时通常不必接时间状语,表示现在时间的now,today有时也与其他时态连用,但下面的时间状语几乎总是与现在进行时连用:
at present, presently, currently, nowadays, these days。当现在进行时与时间状语always, forever连用时,表达经常发生的习惯性动作,尤其是刚刚发生的或暂时性的习惯动作。比如:He is always playing football at weekends.The little boy is forever asking questions.这种用法常用来表示说话人褒义或贬义的情感色彩,如赞许、批评、喜欢、厌恶等。
6.有些动词通常不能用现在进行时。这些词通常是表示“感觉、感情、存在、从属、思维”等的动词。这些动词通常只用于一般式,不用于进行式。如:
(1)表示感觉的动词:see,hear,smell,taste,feel,notice,look,
seem,appear。
(2)表示感情的动词:hate,love,fear,like,want,wish,prefer,
refuse,forgive。
(3)表示存在状况:be,exist,remain,stay,obtain。
(4)表示从属或占有:have, possess,own,contain,belong,consist of,form。
(5)表示思考、理解:understand,know,believe,think,doubt,
forget,remember。
(1)我知道英语时态的类别。
(2)我能够准确回忆一般现在时的各种形式。
(3)我能够准确回忆一般过去时的各种形式。
(4)我能够准确回忆一般将来时的各种形式。
(5)我能够尝试写出现在进行时的各种形式。
(6)我能够将现在进行时的用法梳理成思维导图。

Tips:
从上面的练习中,你发现了现在进行时中动词-ing形式的转变规律了吗 大部分动词都是直接加-ing即可;以不发音字母e结尾的动词,先去掉e再加-ing,如write→writing;以重读、闭音、单辅音字母结尾的动词,双写这个辅音字母再加-ing,如run→running(注意:单音节单词中有两个元音的动词无需双写,如iron→ironing); 以字母ie结尾的动词,先将ie变为y再加-ing,如lie→lying; 以c结尾的动词,变c为ck再加-ing,如picnic→picnicking。

新单词 简要英语释义+中文
Trees Need Not Walk the Earth
by David Rosenthal
Trees need not walk the earth
For beauty or for bread;
Beauty will come to them
Where they stand.
Here among the children of the sap
Is no pride of ancestry:
A birch may wear no less the morning
Than an oak.
Here are no heirlooms
Save those of loveliness,
In which each tree
Is kingly in its heritage of grace.
Here is but beauty’s wisdom
In which all trees are wise.
Trees need not walk the earth
For beauty or for bread;
Beauty will come to them
In the rainbow—
The sunlight—
And the lilac-haunted rain;
And bread will come to them
As beauty came:
In the rainbow—
In the sunlight—
In the rain.

3.外国人怎么挑选和装饰圣诞树 请阅读以下文章并完成填空。
Having a Christmas tree in your home is one of the best parts of Christmas.There are many fun Christmas tree traditions.
Picking out a tree is one of the first things you can do.Families will get together and go to a tree farm to pick out their favourite tree.Every tree is unique(特别的), so it’s fun to discuss this with family members and find the best one.Some tree farms will cut the tree down for you; other farms will let you cut it down yourself.
After you bring the tree home, it’s time to decorate it.You can hang strings of little lights on the tree, as well as bulbs(灯泡) or even small pieces of candy and fruit.Some families even have special decorations that are passed down through many generations.
But there is also some debates about Christmas trees—whether real trees are better than “fake” trees.
Many say fake trees are more convenient—they don’t need to be watered and they can be stored and reused for many years.They are also cheaper than real trees.But people who prefer real trees say that these trees are more environmentally friendly.Fake trees are made out of plastic
(塑料).They can last longer, but if thrown away, they will be bad for the environment.Also, real trees have a pleasant smell.It is nice to walk into your home after a long day at school and smell the scent(气味) of a real pine tree.

(2022 山西临汾三模改编)
Forests are home to many plants and animals.They also matter to humans in different ways.In China, Tree Planting Day arrives on March 12.It was set up to remind people about the importance of forests.
China planted 3.6 million hectares of forest in 2021, according to the National Afforestation Committee(国际造林委员会).That’s more than double the area of Beijing.The committee called on all adults to plant three to five trees a year.During the past 40 years, volunteers planted nearly 79 billion trees across China.China has become the country with the largest increase in forest resources(资源)and the largest area of planted forests.
People are also encouraged to take part in greening projects.Here’s an app that can help.Users get “green energy” points through daily actions, and the project will plant real trees for them.More than 600 million Chinese have used this app to live greener lifestyles and help protect the environment.The project has planted more than 360 million trees in China since 2016.
Besides big projects, China also focuses on(专注于)small actions in cities.The committee says China now has more than 20,000 “pocket parks”—mini parks in cities.It has also built more than 80,000 kilometres of green pathways(道路)
across the country.
In the future, China will take more actions to help our environment so that we can reach the goal of achieving carbon neutrality(碳中和) before 2060 successfully.
1.Please translate the underlined sentence into Chinese.
　 .

2.How many percent of China’s forest coverage were
increased from 2003 to 2021
　 　
3.What small actions has China taken to go green
　 .
　
它(植树节)的设立是为了让人们意识到森林的重要性。/设立它(植树节)的目的是让人们明白森林很重要。

4.What can you do for our country’s greening projects

答案不唯一,联系实际符合问题要求即可,比如不使用一次性筷子、乘坐公共交通工具等。参考答案为I will not use single-use chopsticks./ I’ll choose public transport if possible when travelling.

(2022 山西太原二模改编)
From grass to trees, plants come in all colours, shapes and sizes.There are about 350,000 types of plants in the world.Let’s enter the world of plants and learn more about them.
How do plants make food
Like all living things, plants need food to live.They make food for themselves by photosynthesis(光合作用).This happens in the leaves.To make food, plants need sunlight,
　　 　 and H2O.They use the energy from the sun to turn all of those things into 　　　　 and sugars.
What do we not really know about plants
◆Fighting
Plants fight against each other to live.Only two percent of the sunlight gets to the forest floor.That’s why some plants spread their leaves to fight for sunlight.
◆Helping each other
Plants also help each other and even communicate.In deserts, the roots of Euphrates poplar(胡杨的根) are connected.If a tree finds water, it will share it with others through the roots.
◆Defending
Each kind of plant has its own ways to protect itself.
Some flowers give off a bad smell.Some even have teeth.
Mimosa pudica(含羞草):When you touch it, it folds up its leaves.Scientists believe this helps the plant fight enemies.The sudden movement of its leaves can scare enemies away.
Why are plants important to us
◆Air
Plants can provide us with clean air.They take in CO2 and make O2 humans and animals need.They make 98% of O2 we breathe.
◆Water
Plants help clean water and reduce floods.An evergreen tree can hold more than 15,000 litres of water per year, reducing the risk of flooding.
◆Food
The world’s food supply depends on about 150 plant species(物种).Just 12 plant species provide three-quarters of the world’s food.
A report has showed that 140,000 plants are at risk of disappearing.To protect these plants, five national parks were set up in China. And the first National Botanical Garden opened in Beijing in 2021.They will play an important part in protecting the endangered plants.
1.Please fill in the blanks in Paragraph 2 according to the
picture.
　 　
2.Why do some plants spread their leaves
　 .
　
CO2 / Carbon Dioxide;O2/Oxygen
Because they need to fight for sunlight./ To fight for sunlight.
3.What does the writer want to show by using the example of
mimosa pudica
　 .
.
　
4.How do trees help to reduce the risk of flooding
　 .
　
5.Please translate the underlined sentence into Chinese.
　
The writer wants to show that each kind of plant has its own ways to protect itself./ Each kind of plant has its own ways to protect itself.
By holding water./ They hold water to help reduce the risk of flooding.
为了保护这些植物,中国成立了五个国家公园。
