8. He won the game from 1999 till 2005.
也可以说成这个吗:He won the game from 1999 to 2005.

1.trouble 指得是麻烦,
question 是需要“解答”的问题,而problem 是需要“解决”的问题。 Question 是往往是“疑问”,但problem 所指的问题,往往是“老大难的问题”。这两个词在实际使用中,一般不能相互替代。 例如
Please answer the following questions.
请回答以下问题。(这句话常出现在作业和试卷,可不能说please answer the following problem).We have 10 people here, but the van has only 7 seats. This is really a big problem.
我们这里有十个人,但这面包车只有七个座位,这可是个大问题。我用以下这句英语,来概括两者的区别吧:
If there is a question, you need an answer. If there is a problem, you need a solution
2.be important to sb. ...对sb.而言是很重要的,强调对某人很重要的东西
eg.

Money is important to me.

be important for sb.(to do sth.):某人……是很重要的,强调做某事对某人的重要性。
eg.
It is important for you to get there early.
3.fast即可作形容词也可作副词,都用来描述具有物理性质的、量化的“速度、速率”的快慢,如:

Tom runs faster than Peter.

4m/s is faster than 2m/s.

而quickly只用作副词,多用来形容无量化的快慢,如:

Quickly Tom! Come here! (which means: Tom! Come here quickly!)

Do it quickly, or we'll be knocked out!
4.ahead是副词
5.这里 straight 的词性是形容词,用来形容另一个副词 ahead,straight的形容词和副词形式相同,不存在 straightly
6.
other后接单复数均可,other one或other two students.

others只能作代词,意思是“其它的人(物或事等)”,常用来泛指。

the other也是既能作形容词,又能作代词。但它一般用来表示总数为二时的“另外一个”,经常与one搭配。 other也能既作形容词又可作代词,意思是“别的,另外的”。

the others也只能作代词,意思与others相近,但常用来特指。

any other 后接复数名词,表示“一些其他……”;any other后接单数名词时,表示“其他任何一个……”。

another作形容词时,是指在原有的基础上再加一(些),表示“再一(些)”或“另外一个(些)”的意思,在心理上至少有三个。 another还可作代词,意思与作形容词时一样。它前面不能加任何冠词,后面也不能加s

7.till / until在表达方式和意义上的特殊性:until是till的强调形式,但是它们表达的意义是相同的,都表示"直到某时"。不过,当主句是否定句时,它引出的意思是"直到(某时)(某动作)才(发生)" ,这时候常会出现"not until …"的结构,如果将 "not until …"的结构放在句首,那么主句要写成倒装句。例如:
He didn't go to sleep until 12 last night .
他昨晚直到十二点钟才睡觉。
They didn't realize their fault till we pointed it out to them .
直到我们向他们指出了他们的错误,他们才意识到。
Not until we pointed out their fault to them did they realize it .
直到我们向他们指出了他们的错误,他们才意识到。
但是,当主句是肯定句时,它引出的意思是"直到(某时某动作停止了)" 。例如:
The students made much noise till the teacher came into the classroom .
直到老师走进教室学生们才停止了大声喧哗。
The young couple were very happy until they used up all their money .
那对年青夫妇直到花光了所有的钱才沮丧起来。
另外,until 可以放在句首而till则不行。我们可以说:Until they used up all their money, the young couple were very happy .我们却不可以说:Till they used up all their money, the young couple were very happy .

此两个连词意义相同。肯定形式表示的意思是"做某事直至某时",动词必须是延续性的。否定形式表达的意思是"直至某时才做某事"。动词为延续性或非延续性都可 以。 正确使用这两个连词的关键之一就在于判断句中的动词该用肯定式还是否定式。

肯定句:
I slept until midnight. 我一直睡到半夜时醒了。
Wait till I call you. 等着我叫你。
(在肯定句中可用before代替 Let's get in the wheat before the sun sets.)

否定句:
She didn't arrive until 6 o'clock.
她直到6点才到。
Don't get off the bus until it has stopped.
公共汽车停稳后再下车。
I didn't manage to do it until you had explained how. 直到你教我后,我才会做。

1)Until可用于句首,而till通常不用于句首。
Until you told me, I had heard nothing of what happened.
直到你告诉我以前,出了什么事我一点也不知道。
2)Until when 疑问句中,until要放在句首。
---Until when are you staying? 你呆到什么时候?
--- Until next Monday. 呆到下周一。

注意:否定句可用另外两种句式表示。
(1)Not until …在句首,主句用倒装。
Not until the early years of the 19th century did man know what heat is.
直到19 世纪初,人类才知道热能是什么。
Not until I began to work did I realize how much time I had wasted.
直到我开始工作,我才认识到了我已蹉跎了几多岁月。
(2) It is not until… that…
