對于英語的學習,我們要掌握正確的學習方法。下面是學習啦小編為大家收集整理的9年級英語知識點,相信這些文字對你會有所幫助的。
9年級英語知識點(一)
weekend用法
1.weekend指“周末”,在5天工作制的國家,指星期六和星期日;在6天工作制的國家,指星期日,與weekday(周日)相對,為可數(shù)名詞。如:
We must go and have a weekend there. 我們應當?shù)侥抢锒戎苣?/p>
We spend alternate weekends at our country cottage.
我們每隔一周到我們的鄉(xiāng)間住宅過一次周末。
2.表示“在周末”,英語可用 at the weekend或at weekends(用介詞 at 為英國英語,用 on 為美國英語),但習慣上不說 in the weekend 或 in weekends。如:
We usually do our shopping at the weekend. 我們通常利用周末采購物品。
They like to go ballooning on the weekend. 他們周末喜歡乘氣球玩。
Traffic on the roads is heaviest at weekends. 周末的交通最為繁忙。
The library is closed on weekends. 周末圖書館關門。
在美國英語中可省略其前的介詞,即把weekends用作副詞。如:
He works weekends. 他周末工作。
I go yachting most weekends in the summer.
在夏天,我大多數(shù)周末都乘快艇游玩。
若不是表示“在周末”,則可根據(jù)情況與其他介詞搭配。如:
The weather ought to improve after the weekend. 過了周末天氣應當好起來。
Tom is always going away for weekends. 湯姆每個周末總是外出。
Why don’t you and I go away for the weekend? 咱們倆何不到外地去度周末呢?
The weather is stormy and will remain so over the weekend.
今天是暴風雨天氣,整個周末都會是這樣。
Could you oblige me with five pounds until the weekend?
能借我5英鎊嗎,周末還你?
3.當weekend與this, that, last, next, every等搭配時,其前不用介詞at或on。如:
We are expecting guests this weekend. 我們本周末要來客人。
Accidents due to driving at high speed were very common that weekend.
在那個周末因高速駕駛造成的交通事故很多。
Tomorrow’s difficult. I’d rather yon came next weekend.
明天有困難,我希望你下周末來。
Peggy was pretty rude to my family last weekend.
佩吉上個周末對我家人很不禮貌。
We go boating on the lake every weekend. 我們每個周末都到湖上劃船。
9年級英語知識點(二)
Since 用來說明動作起始時間,for用來說明動作延續(xù)時間長度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:并非有for 作為時間狀語的句子都用現(xiàn)在完成時。
I worked here for more than twenty years. (我現(xiàn)在已不在這里工作。)
I have worked here for many years.(現(xiàn)在我仍在這里工作。)
注意:用句型轉換的方法,很容易排除非延續(xù)動詞在有for/since結構的完成時中的誤用。
(1)(對)Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
(2)(錯)Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對,它應改為 Harry got married six years ago. 或 Harry has been married for six years.

副詞的基本用法
副詞在句中主要用作狀語,修飾動詞、形容詞、副詞、介詞短語或句子。
(1)修飾動詞,表示時間、地點、程度、方式、頻度等。一般位于動詞之后,如果動詞有賓語,則要位于賓語之后。頻度副詞常位于助動詞和連系動詞be 之后或實義動詞之前。例如:He arrived only yesterday. 他是昨天才到的。There were clothes lying here and there on the floor. 地板上到處都是衣服。I have been terribly worried about you all day. 我一整天都非常為你擔心。She plays the piano very well. 她鋼琴彈得很好。The boy is always asking his parents for money. 那個男孩老是向他父母要錢。She never goes to the cinema. 她向來不看電影。
(2)修飾形容詞、副詞、介詞短語,一般前置,只有enough例外,需要后置。例如:She seems quite happy. 她看上去相當愉快。You've done rather badly in the test. 你考得夠糟糕的。The wind was right in our faces. 風迎面吹來。This girl is not old enough to go to school. 這個女孩還沒有到上學的年齡。He didn't run fast enough to catch the train. 他跑得不夠快,沒有趕上火車。
(3)用作表語,多為與介詞同形的副詞和表示方位的副詞。例如:Is anybody in? 里面有人嗎?有人在家嗎?Father is away. 父親離家在外。I am downstairs and my brother is upstairs. 我住樓下,我哥哥住樓上。My friend is still abroad. 我的朋友還在國外。
(4)少數(shù)表示地點或時間的副詞還可用作定語,一般位于名詞之后。例如:I hope you'll enjoy your stay here. 希望你在這里過得愉快。I met a friend of mine on my way home. 在我回家的路上,我碰到一位朋友。What did you think of the meeting yesterday? 你覺得昨天的會開得怎樣?
(5)副詞的比較等級用法與形容詞一樣,請參見《初中英語語法專題講座--形容詞》有關內(nèi)容。
