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规则呢 请你写出work一词的时态变化:

二、基础用法梳理

You 　　　　　　　　.
He 　　　　　　　　.
复数 We 　　　　　　　　. We 　　　　　　　　.

特殊疑问句形式和回答
人称 疑问形式 回答
第一人称 What 　　　　 I 　　　　 I 　　　　.
第二人称 What 　　　　 you 　　　　 You 　　　　.
第三人称 What 　　　　 he 　　　　 He 　　　　.
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.和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 the weekends.和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于现在进行时。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。
答案:略
(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形式的变化规律了吗 大部分动词都是直接加-ing即可;以不发音的字母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须双写,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.

The baobab tree(猴面包树),often called the “upside-down” tree,is one of nature’s most interesting creations.Growing mainly in Africa and Australia,this strange-looking tree has a super thick trunk that can store up to 120,000 liters of water—enough to fill 600 baths!If you stand under its bare branches during dry seasons,it really looks like someone planted giant roots pointing at the sky.Local children sometimes joke that the tree was thrown to Earth by ancient gods and grew upside-down.
What makes baobabs special First,they have strong ability to survive.When other trees lose leaves in dry months,baobabs use their stored water like a built-in water bottle.Their gray bark(树皮) acts like armor—if animals destroy it,the tree can grow new bark quickly.Some baobabs live over 1,500 years,becoming natural water stations for elephants and monkeys during dry seasons.
Baobabs help nature in many ways.At night,their big white flowers open under moonlight and get pollinated(授粉) by bats.The fruit called “monkey bread” looks like brown coconuts and has six times more vitamin(维生素) C than oranges!People use every part of the tree:leaves go into soups,bark becomes fishing nets and baskets,
while fruit powder(粉末) makes healthy drinks tasting like lemon candy.Even the empty seed pods are used as musical instruments!
Sadly,these amazing trees face new problems.Climate change brings changeable rains—sometimes no rain for years,sometimes heavy floods.Young baobabs struggle to grow in these conditions because their soft trunks can’t store water well yet.Some of the oldest trees,over 800 years old,suddenly died.Scientists are studying how to protect these natural wonders.

　　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.
