高一英语语法时态注意事项
◆动词时态应注意的几点
1. 瞬间性动词的一般现在时和现在进行时常用来表示将来的动作。例句：
①The film begins in a minute.
②My uncle is leaving tomorrow morning.
2. 在时间、条件、让步状语从句中,常用一般现在时代替一般将来时。例句：
①Every time I listen to that song, I’ll think of my old friend.
②If you do that, I shall be very pleased.
③They’ll stand by you even if you don’t succeed.
3. 一般过去时和现在完成时的区别：一般过去时和现在完成时都表示过去所发生的动作，但现在完成时强调这一动作与现在的关系，如对现在产生的影响、结果等，所以它不能和表示过去的时间状语连用;一般过去时只表示过去的事实，不表示和现在的关系,因而它可以和表示过去的时间状语连用。如：
—Have you finished your work?
—Yes, I have.
—When did you finish it?
—I finished it last summer.
◆直接引语与间接引语转换时应注意的几个问题：
1. 人称的变化
2. 时态的变化
3. 时间状语的变化
4. 地点状语的变化
例句：
①Xiao Yi said, “I want to go to the park this afternoon.”
→Xiao Yi said (that) he wanted to go to the park that afternoon.
②Bob said, “We’ll have a meeting here tomorrow morning.”
→Bob said (that) they would have a meeting there the next morning.
◆定语从句中关系代词只能用that和不能用that的几种情况：
只能用that的情况
1. 先行词是不定代词。
例句：Please tell me everything that happened to you.
2. 先行词被形容词级、序数词或only, last, same, very等修饰。
例句： ①This is the most interesting movie that I have ever seen.
②This is the only book that I read during the summer holiday.
3. 先行词既包括人又包括物。例句：She talked about the writer and his works that interested her.
不能用that的情况
1. 非限制性定语从句中。
例句：He said he could speak three foreign languages, which is not true.
2. 先行词本身是that。
例句：I have that which you gave me.
3. “介词+ 关系代词”结构。
例句：The person to whom I talked just now is Tom.
◆现在完成进行时与现在完成时进行的比较：
1. 强调动作还未结束时, 多用现在完成进行时;强调动作的结果时, 多用现在完成时。例句：
①I have been painting the paining. (强调“一直在画”这个动作)
②I have painted the painting. (强调“画完了”这个结果)
2. 有些动词不能用在现在完成进行时中，但可用在现在完成时中。如：have, love, see等。例句：
①She has had a cold for a week.
②They have loved each other for three years.
③I have seen this movie.
-ing形式：
1. having done
having done是非谓语动词中-ing形式的完成式,而doing则是其一般式,它们都与句中主语构成逻辑上的主谓关系,只是doing与句中谓语动词同时发生或基本上同时发生;having done则表示动作或状态发生在句中谓语动词之前。
[例句]
①Hearing the news, they got excited. (hear 和get excited这两个动作几乎同时发生)
②Having arrived at the top of mountain, they took a rest. (arrive 发生在take a rest之前)
2. 动词后接动词的-ing形式和不定式有些动词后既可接动词的-ing形式也可接to do形式作宾语，但意义有所不同。
[例如]
① forget / remember / regret doing sth. 表示动作已经发生;
forget / remember / regret to do sth. 则表示该动作未发生。
② mean to do sth. 表示“打算做某事”;
mean doing sth. 表示“意味着做某事”。
③ try to do sth. 表示“设法尽力做某事”;
try doing sth. 表示“试着做某事”。
④ stop to do sth. 表示“停下来接着做另一件事”;
stop doing sth. 表示“停止做某事”。
⑤ go on to do sth. 表示“(做完某事)接着做另一件事”;
go on doing sth. 表示“继续做同一件事”(= go on with sth.)。
⑥ can’t help to do sth. 表示“不能帮助做某事”;
can’t help doing sth. 表示“情不自禁地做某事”。
3. have/has been doing
have / has been doing是现在完成进行时的构成，强调动作的延续过程，动作可能还在进行。而have / has done是现在完成时的构成，强调动作的结果，该动作通常已经结束。
[例句]
①I have written a book. (动作结束)
②I have been writing a book. (可能未写完，侧重最近一直忙于写书)

There are three branches of medicine . One is called “doctor medicine” , or “scientific medicine”. Scientific doctors try to observe sicknesses , look for logical patterns , and then find out how the human body works . From there they figure out what treatments may work . This kind of medicine is believed to date from the 4th century BC. Although nowadays it is successful , in the ancient world this approach probably did not cure many patients .
A second kind of medicine is called “natural cures,” of “folk medicine ,” in which less educated people try to cure sicknesses with various herbs . These folk healers also use observation and logic , but they are not so aware of it . They try things until they find something that seems to work , and then they keeping doing that . Folk medicine flourished long before the development of scientific medicine and was more successful in ancient times than doctor medicine .
The third kind is called “health saps,” or “faith healing.” Sometimes this may be as simple as touching the holy man and being immediately healed . Other times , a magician may make you a magic charm , or say a spell , to cure you . Some religious groups organize special healing shrines for the sick . In these places people rest , get plenty of sleep , eat healthy food , drink water instead of wine , and exercise in various ways . They also talk to the priests and pray to the gods . If you are feeling depressed or you have been working too hard , going to these places may be just the right thing to make you feel better .

(B)
Net library is a library that lends out digital books. It treats a digital book like a paperback copy. It charges libraries per book per copy and gives publishers a cut of the total income.
From the consumer’s point of view, this means that if more than five people want the latest Danielles Steel romance novel, other people who request that book will get a message saying the title is unavailable. It’s a model many publishers seem to have embraced. More than 350 gave the company rights to hand out their digital works, and McGraw Hill Corporation and Houghton Mifflin Corporation have out money in the company. The California public libraries and about 1,800 others across the US are trying out the Net Library services.
Some librarians criticize the New Library model. Stanford University librarian Michael Keller argues that the company is creating an unnatural fear of digital works, which is contrary to the ideas of the Internet.
Keller and some other librarians argue for the e-book vision set forth by Ebrary. Ebrary is starting a service that lets us users read books for free.
But it will charge about 25 cents a page when a person tries to print out the material or a copy and paste it into a different file or tries to download a copy onto a computer.
Christopher Warnock, chief executive of Ebrary, believes most consumers won’t want to buy entire books, only the parts that interest them.
“There’s not really a lot of good in owning an electronic file and having to store it and manage it. It doesn’t make sense,” he said.
5. The word “embraced” in the third paragraph means __________________.
A. tried out something hard B. disliked something badly
C. taken something willingly D. held something tightly
6. From the second paragraph we can see consumers __________________.
A. complain about the limited number of the new books
B. don’t care if they are charged money
C. don’t like other people borrowing books
D. enjoy the service of the Net Library
7. How do publishers get money from the net Library?
A. They get the money from the readers.
B. They get the money by cutting the cost of the books.
C. They get the money from selling their books to the Net Library.
D. They share the money with the net library.
8. What does the last paragraph mean?
A. It’s reasonable to charge the consumers money for copying some pages.
B. There is no need for consumers to have a whole book.
C. Net Library is not a good way for the consumers.
D. Ebrary is not a good library for the consumers.
