Besides giving off gases and dusts into the air, humans produce waste that is poured on the environment. Often, this waste produced by major industries and people is harmful to both nature and human life.
One of the main causes of the large amount of dangerous waste is that people do not realize how large a problem it is. Because it can be simply removed and sent to a landfill（廢渣填埋場(chǎng)）, the problem is often believed to end there. In addition, industries have often shown an unwillingness to find ways to deal with dangerous waste because of the related expenses. Many industries and governments build simple landfills to store waste, and often just pour waste chemicals into nearby bodies of water. Often, chemicals used for industrial production cause dangerous forms of waste. The amount of these chemicals has increased greatly in the past, but it is often difficult and expensive to get rid of these chemicals or to store them in a way safe to human life and the environment.
Every year, major health problems result from dangerous waste. Sadly, it is often only after someone has died or become seriously ill that governments will take measures to reduce levels of harmful waste.
Some governments have realized how serious the dangerous waste problem is and are now trying to settle this problem. They are also trying to limit the amount of waste industries are allowed to produce.
Not only governments but ordinary people as well must work together to solve the problem. They can choose not to buy those products which require the production of dangerous waste, and produce less harmful waste themselves. Many scientists think that waste production can be cut. The waste can be reduced by at least one third using existing technologies and methods.

Who has deprived the children's happiness of learning???

The physical memory dump(電腦死機(jī)) error is a big problem that affects even the most advanced computer systems．Although it's quite a rare error, it's one of the most stopping what you're doing and restarting your computer—making you lose all your unsaved data．This is a big problem, but there is actually a very easy way to fix it．
There are two reasons why the physical memory dump happens．The first is pretty simple and is to do with the "hardware", and if any of these pieces are not fit for your system, it will cause the physical memory dump．So, if you've recently added any hardware to your PC, then take that out and see if it works．
The other reason is your system, the "registry"．The registry is a big database(數(shù)據(jù)庫(kù))that operates in the background of Windows, storing all sorts of settings and information about your PC．The problem with the registry is that since it has so many important files inside, it's constantly got hundreds of files open every time you use your PC．And because there are so many files to open at once, Windows is constantly getting confused, leading it to save many of these files in the wrong way．These files go wrong when saved wrongly, making them difficult for your computer to read．However, if it can't read the files at all, it has no choice but to stop everything it's doing and restart your PC．This is why the physical memory dump error appears so easily—because when a registry file is so wrong that it can't be read, your computer needs to refresh itself immediately．
This latter reason for causing the physical memory dump is actually extremely common and the likelihood is that your PC is suffering from it, if you're seeing this error．Luckily, it's also incredibly easy to fix—you just need to use a software tool called a "registry cleaner" to go through the registry and fix all the problems in there．
72．From the text we can infer that ________．
A．the dump error often happens to your PC
B．the dump canbe dealt with easily
C．only the advanced computers suffers from the error
D．the dump error can cause the data in your PC to be lost
73．The reason that your PC has the dump error is that ___________．
A．the the hardware loses its memory
B．your Windows needs to be upgraded
C．you have saved wrong files in the PC
D．you have stored too many files in the PC．
74．What’s problem with the registry when your PC goes wrong?
A．The register can’t read the files correctly．
B．It must open 100 files every time you use your PC．
C．The register doesn’t agree with the database．
D．The register must save many important files inside．
75．What does a registry cleaner means?
A．A softwar which can help you save time．
B．A software which can remove unnecessary files
C．A software which can repair the machine．
D．a(chǎn) software which makes your PC down．

There are three separate sources of danger in supplying energy by nuclear power(原子能).
First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.
Third, there may occur the danger of a leak(泄漏) or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster(災(zāi)難) is extremely high.
1.Which of the following is FALSE?
A.It is possible that a leak or an explosion occurs at a power station.
B.It is unusual for radioactive materials to be transported across land.
C.The containers are likely to be broken by an earthquake.
D.Nuclear wastes remain dangerous in most cases for many years. 
2.The author thinks that the ways to store nuclear wastes are ________.
A.easy      B.impossible         C.reasonable        D.ineffective 
3.What do we learn from the last paragraph?
A.The power station is a safe place.
B.The dangers of nuclear energy can be prevented.
C.The general public are strongly against the nuclear program.
By itself, none of the three dangers is very likely to cause much worry.
4.What is this passage about?
A.Uses of nuclear power.          B.Dangers from nuclear power.        
C.Public anger at nuclear power.  D.Accidents caused by nuclear power.

At one time, computers were expected largely to remove the need for paper copies of documents（文件）because they could be stored electronically. But for all the texts that are written, stored and sent electronically, a lot of them are still ending up on paper.
It is difficult to measure the quantity of paper used as a result of Internet-connected computers, although just about anyone who works in an office can tell you that when e-mail is introduced, the printers start working overtime. “I feel in my bones this revolution is causing more trees to be cut down,” says Ted Smith of the Earth Village Organisation.
Perhaps the best sign of how computer and Internet use pushes up demand for paper comes from the high-tech industry itself, which sees printing as one of its most promising new markets. Several Internet companies have been set up to help small businesses print quality documents from a computer. Earlier this week Hewlett-Packard Co. announced a plan to develop new technologies that will enable people to print even more so they can get a hard copy of a business document, a medical record or just a one-line e-mail, even if they are nowhere near a computer. As the company sees it, the more use of the Internet the greater demand for printers
Does all this mean environmental concerns （環(huán)境問(wèn)題） have been forgotten? Some activists suggest people have been led to believe that a lot of dangers to the environment have gone away. “I guess people believe that the problem is taken care of, because of recycling （回收利用）,”said Kelly Quirke, director of the Rainforest Action Network in San Francisco. Yet Quirke is hopeful that high-tech may also prove helpful. He says printers that print on both sides are growing in popularity. The action group has also found acceptable paper made from materials other than wood, such as agricultural waste.
72.   The growing demand for paper in recent years is largely due to ___________.
A.    the rapid development of small businesses    B. the opening up of new markets
C.    the printing of high quality copies               D. the increased use of the Internet
73.   Environmentalists believe one possible way of dealing with the paper situation is ______.
A.    to encourage printing more quality documents
B.    to develop new printers using recycled paper
C.    to find new materials for making paper
D.    to plant more fast-growing trees
74.   Hewlett-Packard Co. has decided to develop new technologies because ___________.
A.    people are concerned about the environment
B.    printers in many offices are working overtime
C.    small companies need more hard copies
D.    they see a growing market for printers
75.   What would be the best title for the text?
A. Computers and Printers                                B. E-mail and the Business World
C. Internet Revolution and Environment                D. Modern Technology and New Markets

Dogs wag(搖擺) their tails in different directions depending on whether they are excited and wanting to move forward or threatened and thinking of moving back,a study has found.
Researchers in Italy examined the tail wagging behaviour of 30 dogs,catching their responses to a range of stimuli(刺激物) with video cameras.To conduct the study they chose 15 male dogs and 15 female ones aged between one and six years.The dogs were all family pets whose owners had allowed them to take part in the experiment at Ban University.The dogs were placed in a large wooden box with an opening at the front to allow for them to view various stimuli.They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the dogs were shown their owners—a positive experience—their tails wagged energetically to the right side.When they were shown an unfamiliar human they wagged to the right,but with somewhat less enthusiasm.The appearance of a cat again caused a right-hand side wag,although with less intensity again.The appearance of a large unfamiliar dog,similar to a German shepherd,changed the direction of tail wagging to the left.Reseachers supposed the dog was thinking of moving back.When the dogs were not shown any stimuli they tended to wag their tails to the left,suggesting they preferred company.While the changes in the tail wagging were not easily noticed without the aid of video,it was thought that the findings could help people judge the mood(心情) of dogs.Computer and video systems,for example,could be used by professional dog trainers to determine the mood of dogs that they were required to approach.
小題1:The video cameras were used to catch the dogs’ responses because _______.
A．it was easier to catch the dogs’ response changes in the tail wagging
B．the dogs were put in the wooden boxes and tested one at a time
C．they enabled the dogs’ owners to know about their dogs’ habit
D．the dogs wagged their tails in different directions when they were in different moods
小題2:The underlined word “intensity” in the passage means _______.
A．surpriseB．worry
C．excitementD．interest
小題3:When there are no stimuli,a dog will _______.
A．wag to the leftB．wag to the right
C．not wag at allD．wag to the left and then to the right
小題4:The underlined word “they” refers to _______.
A．the dogsB．the trainers
C．the systemsD．the researchers
小題5:The purpose of doing the experiment is _______.
A．to train dogs for their owners
B．to help people judge the mood of dogs

　　Forests have always been useful and important to man who makes use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from terrible heat. They're also useful in preventing good and rich top soil from being washed away during heavy rains.
　　If there were no trees, heavy rains would wash away the rich top soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but man in the past had no enough knowledge about science of nature, they cut down too many trees in the area where they lived and never planted new ones. By and by the rich top soil was blown and washed away by strong winds and heavy rains. In the end the rich land changed into useless deserts where nothing could grow.
小題1:According to the passage, ______.
A．a(chǎn) long time ago, man didn't know how to make use of wood
B．trees are not as useful as they were in the past
C．trees were more found in the past than they are today

D
The oldest forms of medicine are enjoying a comeback. Modern holistic medicine is an approach that treats the whole patient, not just the disease. It is a way to maintain good health rather than cure illness. The most important influences on today’s holistic medicine are ancient Chinese medicine and Indian Ayurvedic medicine, both of which promoted whole body health.
Holistic medicine usually combines diet, physical exercise and meditation, together with other alternative techniques such as massage(按摩) and acupuncture(針炙). Herbal treatment, a practice of treating illness by using plants, is influenced by the writings of Culpeper as well as Chinese and Ayurvedic medicine. Homeopathy(順勢(shì)療法) is one of the forms of holistic medicine which is widely practiced in Europe and the USA. Homeopathy began in Germany in the early 1800s, when Samuel Hahnemann described how very tiny doses(劑量) of a drug had an effect on his patients. According to Hahnemann, the more the drug was diluted(稀釋), the stronger its effects. The substance selected would produce similar effects to the disease itself if given in large doses. In the UK homeopathy is regarded as a non-traditional but just about acceptable treatment.
Meditation and contemplation have an important role in holistic medicine. They were brought to Europe by Indian teachers who combined Indian Ayurvedic medicine with Western beliefs. Transcendental meditation(超脫靜坐) is one of the best known of these techniques. People repeat words inside their head to reach a state of deep relaxation.
The holistic movement has made many doctors look at the whole patient, not just the disease. Life-style, emotional problems and diet are just some of the factors that can affect a person’s health. Holistic medicine emphasizes good diet, exercise and fresh air, all of which contribute to health. Some clinics now offer holistic medicine along with traditional treatments, so that their patients can choose a combination of treatments that suits them. One problem with holistic medicine is that it is difficult for people to be sure a doctor is reliable. To solve this, many countries want alternative doctors to form professional bodies.
51．Modern holistic medicine centres upon        .
A．curing a disease                                          B．herbal treatment
C．continuous development                          D．keeping patients healthy
52．Which of the following does NOT belong to holistic medicine?
A．massage                                                     B．meditation
C．a(chǎn) balanced diet                                       D．a(chǎn) knee operation
53．The principle of homeopathy is that        .
A．the large doses of medicine that will not be harmful will take better effect
B．the disease will be cured sooner by taking larger doses of medicine
C．a(chǎn) small thinner dose of medicine will be more effective
D．the doses of medicine depend on how serious the illness is
54．Which of the following titles best sums up the passage?
A．Holistic Medicine                                       B．Traditional Medicine Returns
C．History of Medicine                                D．Combination of Treatments Works
55．What can we infer from the passage?
A．Relaxation is the key of holistic treatment.
B．Holistic medicine needs to become more trustworthy.
C．Holistic treatment is more beneficial than traditional treatments.
D．Holistic medicine will become the most welcome treatment soon.
