据专家权威分析，试题“I often _____________books at the weekends, but last weekend..”主要考查你对一般现在时，动词单数第三人称，否定句等考点的理解。关于这些考点的“档案”如下：

一般现在时，动词单数第三人称否定句

考点名称：一般现在时，动词单数第三人称

一般现在时：
表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。可概括为
①经常性或习惯性动作；
②长期存在的特征或状态；
③普遍真理、客观事实等。
构成：
一般现在时用行为动词的原形，但第三人称单数作主语时，动词的词尾要加-S。
a. 表示经常性或习惯性的动作。
例：Li Ming always helps the old man. 李明一直帮助这位老人。
We usually go to school on foot. 我们通常步行上学。
They sometimes go fishing on Sundays. 他们有时周日去钓鱼。
b. 表示永恒不变的事实或真理。
例：A bird flies with wings. 鸟用翅膀飞翔。
c. 用在格言、谚语中。
例：Pride goes before a fall. 骄者必败。
一般现在时具体用法:
1.表示经常的或习惯性的动作，常与表示频率的时间状语连用。
时间状语：
always，usually，every morning/night/evening/day/week/year，often，sometimes，
occasionally，from time to time，twice a week，rarely,seldom，once a month，hardly，ever,never.
e.g： I leave home for school at 7:00 every morning.

2.表示主语具备的性格、能力、特征和状态。
e.g：I don't want so much.
Ann Wang writes good English but does not speak well.
比较：Now I put the sugar in the cup.
I am doing my homework now.

3.表示客观事实和普遍真理。
e.g ：The earth moves around the sun.
Shanghai lives in the east of China.

4.在时间状语从句和条件状语从句中，常用一般现在时代替将来时。

5.表示预先计划或安排好的行为。

6.小说故事用一般现在时代替一般过去时。新闻报道类的内容，为了体现其“新鲜”性，也用一般现在时来表示过去发生的事情。

7.有些表示状态和感觉的动词表示现在发生的具体行为时，只用一般现在时，而不用进行时态。

8.表示现在发生的具体动作或存在的状态

9表示格言或警句中。　e.g Pride goes before a fall.　骄者必败。
注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。
例：Columbus proved that the earth is round..
第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。
再如：Now watch me,I switch on the current and stand back.
第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。

否定转移的形式与用法：
一、动词的否定转移
1.形式上否定主句的谓语，实际上是否定从句的谓语
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”的主语是第一人称，谓语动词为没有任何副词修饰的一般现在时，它们的否定式实际上是对宾语从句的否定。
表示说话者提出一种委婉的看法或主张。如：
I think that he will help us.——I don’t think that he will help us. 我认为它不会帮助我们。
I believe that he is right.——I don’t believe that he is right. 我认为他不对。
I suppose that he likes it.——I don’t suppose that he likes it. 我想他不喜欢它。

2. 形式上否定谓语动词，实际上否定复合宾语
当动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”、“find”的主语是第一人称，谓语动词为没有任何副词修饰的一般现在时，它们前面的否定式实际上是对复合宾语的否定。表示说话者所提出的一种委婉的看法或主张。如：
I think math difficult. — I don’t think math difficult. 我认为数学不难。
I find the story interesting. — I don’t find the story interesting. 我认为这个故事没有趣。
I expect so. —I don’t expect so. 我认为不会。

二、动词“think”、“believe”、“suppose”、“imagine”、“expect”、“feel”在下列情况下，否定不转移：
1.这些动词跟其他另一个动词一起做并列谓语时，否定不转移。如：
I believe and hope he won’t do that. 我相信并且也希望他将不会那样做。
I feel and admit that we are not foolish. 我觉得并且也承认我们并不愚蠢。

2.用于疑问句时，否定不转移。如：
Do you think it is not going to rain? 你认为天不会下雨吗？
Don’t you believe that he has done a good thing? 难道你不相信他做了一件好事？

3.用作插入语时，否定不转移。如：
Li Lei, I think, won’t be angry with you. 我想李蕾不会生你的气。
Tom, I suppose, won’t be against it. 我猜想汤姆不会反对。
Mike, I believe, hasn’t seen the film. 我认为迈克没有看这场电影。

4.动词前有其他副词修饰时，否定不转移。如：
I really don’t think it’s necessary for us to go there now. 我的确不认为我们有必要去那儿。
I feel strongly that he shouldn’t do such a thing. 我强烈地认为他不应该做那样的事。

5.动词为非一般现在时或主语不是第一人称时，否定不转移。

He thinks that he isn’t fit for the job. 他认为他不适合这件工作。

6.当宾语从句中含的否定为“not……at all”、“not a little”、“not a few”、“not enough”、“can’t help”等固定搭配时，否定不转移。如：
I think that he doesn’t know it at all. 我想他对那一点也不知道。
I suppose that it is not enough to remember the words if you want to learn the language well. 我认为如果你想把这门语言学好，那么只记单词是不够的。
I believe that you can’t help singing our national anthem when you win the first place in the Olympic Games. 我相信当你在奥运会上获得第一名时你会情不自禁地唱起国歌来。

7.当宾语从句中含“no”、“nothing”、“nobody”、“nowhere”、“hardly”、“seldom”、“little”、“few”等否定词或半否词时，否定不转移。如：
I believe that nothing can make me give it up. 我想任何事情也不能使我放弃。
