题目内容

A scientific report has found that snow and ice on Africa’s highest mountain Kilimanjaro ______rapidly and could vanish within 20 years.

A．has been melted	B．will melt
C．is melting	D．was being melted

解析试题分析：句意：一份科学报告表明：非洲最高的山脉乞力马扎罗山上的积雪和冰层正在快速融化，并可能在未来20年内彻底消失。表示现在正在进行的动作，故用现在进行时。
考点：时态考查题
点评：这种用法往往表示发生在过去，说话时没完成，仍在继续进行的动作或状态。做题时可以从上下文推断应选用的时态。主句用了现在完成时，从句中不会用过去进行时，从句中后半句中用了将来时，那么前半句就应该比将来时早一步，即“现在”，选项中A是现在完成时，C是现在进行时，根据主语和动词的关系可以排除A。

Teaching a child to read at a young age gives him a valuable start in life. Reading is the basic part of education and a child’s reading ability will influence his school success greatly. Learning difficulties, many of which begin from poor reading skills, can damage a school child’s confidence and affect his future achievement. Young children are programmed to learn and they can learn better with encouragement. Ten to twenty minutes of reading a day still leaves plenty of time for play.

Many parents are concerned that learning to read is too challenging a task for a pre-school child, but they should also remember that most children learn to speak by the time they are 3. Learning a language is probably the single most challenging task any individual can undertake, yet children do it without formal instruction, achieving the fluency much better than adult language students.

There is a window of opportunity in terms of IQ development, which is most open during a child’s early years. A scientific study, carried out by Dr. Peter Huttenlocher at the University of Chicago, showed that the number of connectors, called synapses（神经元突触）, between the nerve endings in a newborn baby’s brain is similar to the number in the average adult brain. These synapses increase rapidly during early childhood. By 12-24 months a child’s brain has about 50% more synapses than the average adult brain. After that the synapses which are not in use begin to atrophy（衰退）. For most people, from age 16, the number remains steady. It begins to drop again as we move into our golden years. Doing intellectual activities at a young age, such as learning to read, can stimulate（刺激）and preserve these connectors in the brain resulting in a long-term beneficial（有益的）effect on IQ development.

Another notable study is probably the Milwaukee project. This study took a group of babies, all of whose mothers had low IQs, and gave them special training for seven hours a day, five days a week, until they started first grade. By the age of 6 these children had an average IQ 30 points higher than their contemporaries. The overwhelming conclusion is that the early intellectual stimulation can have a positive, long-term effect on a child’s brain development.

From birth you should talk to and explain things to your baby. Reading to him can be a wonderful way of spending quality time with your child. The enjoyment of books and being familiar with the idea of print will pave the way for（为……铺平道路）learning to read later.

If your child is a fast learner you can help him realize his potential by introducing him to the joy of the printed word at an early age. This will lay the foundations（基础）for both a high achieving school career and a lifelong love of reading. If your child shows early signs of reading difficulties, your efforts may help him get rid of such problems before he goes to school.

It can be difficult to teach your own child because emotional（引起情绪激动的）issues arise easily. Online programs for learning to read English are excellent options. They allow children to repeat new materials as many times as they need to, without wearing out the parents’ patience.

Test-taking tips

Do you sweat, check your pencil, and feel butterflies in your stomach as your teacher hands out the test paper? A lot of people feel anxious when it is time to take a test. Here are some tips for taking tests:

1 .Your memory recall will be much better if you have had enough rest. In a scientific study, people who got enough sleep before taking a math test did better than those who stayed up all night studying.

Read the test through first. Once you have the test paper in front of you, read over the entire test, checking out how long it is and all the parts that you are expected to complete. 2 .If something seems unclear before you start, do not panic: ask the teacher.

Focus on addressing each question individually. 3 . Instead, answer the best way you can or skip over the question and come back to it after you have answered other questions.

Relax. 4 .Of course you can not get up and move around in the middle of a test, but you can wiggle (扭动) your fingers and toes, take four or five deep breaths. As we all know, It can be easy to forget things we know well. During a test, if you forget something and start to get tense, it suddenly becomes much more difficult to remember.

Finished already? Although most teachers will let you hand your test paper in early, it is usually a good idea to spend any extra time checking over your work. 5 .On the other hand, if you have 5 minutes until the bell rings and you are still writing, wind up whatever you are working on without panic.

A. Be sure you have studied properly.

B. Get enough sleep the night before the test.

C. This will allow you to decide how much time you have for each section.

D. As you take the test, if you do not know an answer, do not worry about it.

E. As the teacher hands out the test paper, be sure you know what is expected of you.

F. You can also add details that you may not have thought you’d have time for.

G. If you are so nervous that you blank out, you might need a mini-break.

Paracutin was born in Mexico in February, 1943. At the end of one week Paracutin was 500 feet high, and it is now over 9, 000 feet high. Today Paracutin is asleep.

What is Paracutin? It was the first volcano(火山) in the world which was seen from its birth right up to the present day. On February 20, 1943, a peasant and his wife set out to work in their corn fields from the Mexican village of Paracutin. They were surprised to find the earth warm under their feet. Suddenly they heard noises deep in the earth and a small hole appeared in their field. In the afternoon there was a sudden loud noise and stones were thrown high in the air. The peasants ran from the field and turned to watch. They saw the birth of a volcano.

Large quantities of stone and lava(岩浆) broke out and a little hill began to form. By evening this hill was 100 feet high and hot ashes(灰烬) were falling on the village. At night the strong light of the hot lava lit up the countryside. The trees near the village were killed and the villagers had to leave their houses. When the village was destroyed, its name was given to the volcano. The news quickly reached Mexico City, far to the east. Many people came to watch the scene. The volcano grew and grew for ten years and hundreds of square miles of forest were destroyed. Then Paracutin went to sleep.
