九年级英语根据首字母填空困难题查看答案及解析

(C)

Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood-powered or coal-powered stoves.

One way to reduce the number of deaths is through cooking equipment powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the "Sol-4". "It is four square meters of mirrors, six to eight meters in length. It is quite a large cooker. "

The "Sol-4" works by reflecting (反射) light from the sun off large mirrors. The mirrors direct (把……对准) the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.

The cooker is also much "friendlier" than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals （人）would be less likely to have breathing illnesses from harmful smoke.

At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.

Each cooker costs about $2,000, which is a large amount of money for most Africans. To solve that problem. Crosby Menzies has created a non-governmental organization called Solar Cookers for Africa. It plans to raise money through donations to provide poor people with solar cooking equipment.

1.This passage is mainly about _______ .

A. solar cooker B. smoke pollution C. solar power experts D. breathing illnesses

2.The "Sol-4" is mainly used to _______ .

A. shorten the time of cooking

B. reduce the cost of making cookers

C. raise money through donations to help African people

D. reduce the number of deaths caused by harmful smoke

3.Which of the following about the "Sol-4" is TRUE?

A. It is six to eight square meters of mirrors.

B. It can work in any weather condition now.

C. It can also heat the pan by lighting firewood.

D. It is more environment-friendly than other cookers.

4.From the passage, we can infer that _______ .

A. the "Sol-4" will be designed in a smaller size

B. more Africans can use the solar cookers in the future

C. the "Sol-4" is the first product of the South African company

D. the African government will provide poor people with solar cookers

九年级英语单项填空简单题查看答案及解析

American cities are similar to other cities around the world: In every country, cities reflect（反映）the values of the culture. American cities are changing, just as American society is changing.

After World War Ⅱ, the population of most large American cities became smaller; however, the population shifts（转移）to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents（居民）became richer. They had more children so they needed more space. They moved out of their flats in the city to buy their own homes. They bought houses in the suburbs（郊区）.

Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young people are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and what the city offers.

This population shift is bringing problems as well as some advantages. Countless poor people must leave their flats in the city because the owners want to sell the buildings or make flats for sale instead of for rent（租金）. In the 1950s, many poor people did not have enough money to move to the suburbs; now many of these same people do not have enough money to stay in the cities.

Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems. One thing is sure: many dying cities are alive again.

1.The main idea of the passage is _________.

2. Why did American city residents want to live in the suburbs after World War Ⅱ?

3. According to the 4th paragraph, a great many poor people in American cities _________.

4.We can know from the passage that _________.

九年级英语阅读理解中等难度题查看答案及解析

The growth in skyscrapers (摩天大楼) worldwide, most of which have large glass panes, has led to a great need for window washers. Though the job, which earns workers as much as $35 an hour, can be lucrative, accidents are not uncommon. However, the dangerous chore may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (监督) from the safety of the ground.

Much like humans, Ozmo, hanging off the sides of the building, uses its arms and brushes to clean the dirt and grime on the glass panes. A 3-D map of the building programmed into its system allows the robot to skillfully move up and down. Computer vision and touch sensors (传感器) enable it to move out of the way in case of unexpected events, such as the sudden opening of a window. And the robot will self-correct and move around it so as not to break a window.

Unlike other window washers, the robot cleaner does not require soap or Windex to clean the glass. Instead, it uses purified water (纯净水) and a process called reverse osmosis (反渗透) to do the job. It is environmentally friendly.

While it takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers, only making their jobs safer. Human workers will control the robot from below.

Whether Ozmo, which is still undergoing testing, docs as good a job as humans remains to be seen. * Past efforts to use a robot to do this dangerous job have not been successful, because the machines do not have the same eye as humans and often miss the soot (烟垢) collected on window corners.

1.The underlined word “lucrative” in the passant’ probably means “________”

A.安全的 B.危险的 C.赚钱的

2.The second paragraph mainly tells us

A.why Ozmo is much more intelligent than human workers

B.how Ozmo works to clean the glass smartly

C.what makes Ozmo an intelligent window cleaning robot

3.What does Ozmo use to clean the glass?

A.Purified water. B.Soap. C.Grime or soot.

4.To finish the task of cleaning the windows of a 40-story glass building, Ozmo spends ________ hours less than a cleaner.

A.560 B.400 C.1,360

5.Which of the following is TRUE about Ozmo?

A.As an intelligent window cleaning robot. Ozmo is successful.

B.Ozmo does harm to the environment while cleaning the window.

C.Ozmo can make human window washers do their jobs safely.
