The following are the results of the tests done by “Family and Home Magazine” on some Pocket Tape-Recorders on the market now.

Pearlcorder S702 $64
This simple model at the bottom of the Olympus range scored the most points for its excellent quality of recording. Background noise hardly affects the sound and recording from a pocket is perfectly possible, but it doesn’t turn off automatically.
Tape length: 30minutes per side. Weight: 240g.
Sony M9   $49.95
Small and very good looking, Sony’s latest offering scored most for its appearance. Sounds clear, but there is slight machine noise. The big control buttons are a great improvement on some of the complicated little controls on other tape-recorders. It doesn’t switch off automatically, but a red light shows if the machine is still running.
Tape length: 60minutes per side. Weight: 195g.
Sony M400  $115
Lots of little control buttons that make a noise are difficult to use. Recording is good but machine noise loses points. Tape counter and automatic switch-off when tape has finished recording or rewinding are useful.
Tape length: 60 minutes per side. Weight: 230g.
Imperial OEM MC7 $ 29.95
Cheap and simple compared with the rest, but recording is good as long as there is no background noise. Use only its own-make of cassette. No light to show it is on; no fast-forward button and the record button makes a loud noise.
Tape length: 30 minutes per side. Weight: 285g.
Philips 585 $80
Handsome and simple to use, but recording is very poor at more than the recommended distance of 5 cm-designed for dictation. No recording light.
Tape length: 15 minutes per side. Weight: 220g.
【小題1】The machine that produces the best recording with the least unwanted noise is _____.

A．Pearlcorder S 702B．Sony M9C．Sony M400D．Imperial OEM MC7
【小題2】If you want a machine which turns off automatically and weighs very little you should choose _____.
A．Pearlcorder S 702B．Sony M9C．Sony M400D．Philips 585
【小題3】Which of the following allows you to record longest but costs you least?
A．Philips 585B．Imperial OEM MC7C．Sony M400D．Sony M9
【小題4】What disadvantage does only the Imperial OEM MC7 have?
A．No light shows when it is on.B．It requires a special cassette.
C．It picks up background noise . D．The record button makes a noise.

科目：高中英語 來源：2012屆河北省赤城一中高三高考預(yù)測英語試卷（帶解析） 題型：閱讀理解

You are busy filling out the application form for a position you really need; let’s assume you once actually completed a couple of years of college work or even that you completed your degree. Isn’t it tempting to lie just a little, to claim on the form that your diploma(畢業(yè)文憑) represents a Harvard degree? Or that you finished an extra couple of years back at State University?
More and more people are turning to an utter deception(欺騙)  like this to land their first job or to move head in their careers. For personnel officers, like most Americans, value degrees from famous schools. A job applicant may have a good education anyway, but he or she assumes that chances of being hired are better with a diploma from a well-known university. Registrars(注冊主任)at most well-known colleges say that they deal with dishonest claims like these at the rate of about one per week.
Personnel officers do check up on degrees listed on application forms. If it turns out that an applicant is lying, most colleges are unwilling to accuse the applicant directly. One lvy League school refers to them as “special cases”, One well-known West Coast school, in perhaps the most delicate phrase of all, says these claims are made by “no such people”.
To avoid complete lies, some job seekers claim that they “attended” or “were associated with” a college or university. After careful checking, a personnel officer may discover that “attending” means being dismissed after one semester. It may be that “being as sociated with” a college means that the job-seeker visited his younger brother for a football weekend. One school that keeps records of false claims says that the practice dates back at least to the turn of  the century—that’s when they began keeping records, anyhow.
If you don’t want to lie or even stretch the truth, there are companies that will sell you a fake diploma. One company, with offices in New York and on the West Coast, will put your name on a diploma from any number of non-existent colleges. The price begins at around twenty dollars for a diploma from “Smoot State University”. The prices increase rapidly for a degree from the “University of Purdue”. As there is no Smoot State and the real school in Indiana is properly called Purdue University, the prices seem rather high for one sheet of paper.
【小題1】The writer mainly wants to tell us that _______.

A．college degrees can now be purchased easily
B．it is very hard for people to find jobs
C．lying about college degrees is becoming a widespread problem
D．employers are no longer interested in applicants’ actual performances
【小題2】The underlined word “utter” in the second paragraph means “______”.
A．thoroughB．carefulC．incompleteD．spoken
【小題3】Once finding applicants with false diplomas, most colleges would _________.
A．keep the records of themB．drive them out of college
C．a(chǎn)void direct conflicts with themD．a(chǎn)ccuse them of such behavior
【小題4】We can learn from the passage that ________.
A．US employers value their job applicants with a degree from top universities
B．University of Purdue and Purdue University are the same school
C．people with fake diplomas can get their first jobs in the US easily
D．people pay the same price for a fake diploma from different universities

科目：高中英語 來源：2013-2014學(xué)年山東省高三10月份第一次質(zhì)檢英語試卷（解析版） 題型：閱讀理解

Life is to be enjoyed. There’s no point in giving up something you enjoy unless you get something back that’s even better. When people eat more healthfully, exercise, quit smoking, and manage stress better, they find that they feel so much better that it reconstructs the reason for making these changes from fear of dying to joy of living. The latest studies show that when you exercise and eat right:

YOUR BRAIN receives more blood flow and oxygen, so you become smarter, think more clearly, have more energy, and need less sleep. Two studies showed that just walking for three hours per week for only three months caused so many new neurons (神經(jīng)細(xì)胞) to grow that it actually increased the size of people’s brains!

YOUR FACE receives more blood flow, so your skin glows more and wrinkles less. You look younger and more attractive. In contrast, an unhealthy diet, chronic emotional stress and smoking reduce blood flow to your face so you age more quickly. Smoking accelerates aging because nicotine causes your arteries (動(dòng)脈) to narrow down, which decreases blood flow to your face and makes it wrinkle earlier. This is why smokers look years older than they really are.

YOUR GENES change. In May, a study was published in the Proceedings of the National Academy of Sciences showing that changing your lifestyle changes your genes.

YOUR TELOMERES (染色體端粒) get longer. Telomeres are the ends of our chromosomes (染色體) that control how long we live. As telomeres become shorter, then cells age more quickly, thus shortening your life.

 Besides, one of the most interesting findings in the study was that the mothers’ awareness of stress was more important than what was really occurring in their lives. The researchers gave the women a questionnaire and asked them to rate on a three-point scale how stressed they felt each day, and how out of control their lives felt to them. The women who were aware that they were under heavy stress had significantly shortened and damaged telomeres compared with those who felt more relaxed. On the contrary, some of the women who felt relaxed despite raising a disabled child had more normal-appearing telomeres.

In other words, if you feel stressed, you are stressed; if you feel fine, you are fine.

1.Which of the following are good for lengthening one’s life, according to the passage?

① eat healthy food  ② drink plenty of water  ③ take exercise  ④ get up early

⑤ go to sleep early  ⑥ release one’s stress

A. ①③⑥                           B. ①②③                           C. ①⑤⑥                           D. ③④⑥

2.The underlined words “your skin glows” in Paragraph 3 are closest in meaning to _________.

A. your skin becomes white as there is plenty of sunshine

B. your skin becomes smooth as there is much blood in it

C. your skin looks pink as you are healthy

D. your skin becomes soft as you exercise enough

3.In the author’s opinion, when you exercise and eat right, you will experience some changes EXCEPT _________.

A. brains becoming cleverer                                 B. faces having fewer wrinkles

C. arteries turning narrower                         D. genes being changed

4.From the last but one paragraph we learn that _________.

A. mothers will have more damaged telomeres if they raise a disabled child

B. mothers don’t know how to handle stress effectively

C. some women were asked to fill out a questionnaire about educating children

D. mothers’ positive attitudes are the key to managing their stress

5.The best title for the passage would be _________.  

A. Eat better, live better                                         B. Feel better, live longer

C. Less stress, fewer diseases                 D. Smoke more, age sooner

Running like the wind, roaring （咆哮） like thunder, tigers have long been feared and respected as a king of the animal world．But last week a report said that there are no more than 30 wild tigers left in south China．

         This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund．

         The South China tiger, also known as the Chinese tiger, is native to southern China．In the 1950's, there were over 4000 tigers found in mountain forests in the country．But due to the destruction of their natural habitat （棲息地） and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species．

         Sixty-six of the big cats can be found in the cages of a dozen zoos around China．But they are nothing like their wild cousins．They have lost their natural skills such as hunting and killing．If they were set free they could not look after themselves．

         "Breeding has damaged the quality of the species", said Pei Enle, deputy director of the Shanghai Zoo．

         To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa．Four of them have already arrived．Progress has been made as two elder tigers have recovered some of their instincts（本能） and can hunt wild animals by themselves at the African base．

         " South Africans are very experienced in reintroducing big animals to the wild．The country has very good natural conditions for the tigers to learn in", said Lu Jun, office director of the National Wildlife Research and Development Center．" We tried in Fujian Province, but it was not successful as there was not a complete eco-chain（生物鏈） and there was a lack of space．"

The tigers should return to China in 2007 when the reservations in Fujian are ready．

1.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?

A．Because it has lost its natural instincts．

B．Because there is not a complete eco-chain．

C．Because there is no space for it．

D．Because uncontrolled hunting has destroyed its natural living conditions．

2.How is the programme of sending several tigers to South Africa getting on?

A．Its effect still remains to be seen．

B．Two tigers can already compete with their wild cousins．

C．Some of the tigers are already on the road to recovering their natural skills．

D．The tigers should be able to recover their instincts completely by 2007．

3.By saying " but they are nothing like their wild cousins", the writer means that ______．

A．they are no longer feared by other wild animals

B．they don't know how to hunt or kill

C．a(chǎn) complete change has resulted in the species because of breeding

D．to reintroduce them into the wild has become an urgent task

4.What is the purpose of sending young tigers to South Africa?

A．To help the tigers recover their ability to live in the wild．

B．To provide them with a better environment．

C．To get the tigers to go on a tour．

D．To find a complete eco-chain for them．

5.Which one is not the reason for South Africa being chosen as the training place?

A．Because the tigers can hunt wild animals by themselves at the African base．

B．Because South Africans are skilled at dealing with the tigers．

C．Because there is a complete eco-chain and enough space there．

D．Because the country has good natural conditions for the tigers to learn in．
