【題目】Our teacher suggested reading books at ________ least ________ hour a day during the winter holiday.

A.the; aB.a; anC./; aD./; an

【答案】D

【解析】

句意：我們老師建議寒假期間每天至少讀書一小時。

考查冠詞。the定冠詞，表特指；a不定冠詞，表泛指，用于輔音音素開頭的詞前；an不定冠詞，表泛指，用于元音音素開頭的詞前；/零冠詞。分析句子可知，第一處構(gòu)成at least短語，翻譯為“至少”，所以用零冠詞；第二處修飾可數(shù)名詞hour，表示一個小時，又因為hour首字母發(fā)元音，所以用an。故選D。

【題目】閱讀短文，根據(jù)所讀內(nèi)容在文章后表格中的空格里填入一個最恰當(dāng)?shù)膯卧~。

Blood donation is a very important activity. It is an easy and direct way to contribute to social work and helps the community. It helps to save lives and helps those who are in need of blood because of the heavy loss of blood during operations or in accidents. You can always be proud of it after making valuable contributions to society.

Blood donation is not a big problem, but you need to keep a few points in mind.

Before donating blood, make sure that the ferrum(鐵) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. After having a balanced diet, you will feel strong and comfortable to donate blood.

For required hemoglobin(血紅蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.

For a good blood flow in your body, drink at least 6-7 glasses of water every day. Don’t take alcohol(酒) a day before and after giving blood. Do not smoke half an hour before giving blood.

When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity, take a deep breath and try to calm yourself. Don’t join in some other activities.

You need to take care of yourself after donating blood. Take a rest for 15 minutes after completion of the donation. It helps you to feel relaxed. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Don’t join in some activities right away, for example, driving.

【題目】 This week, our topic is pollution. What’s the answer to all of our pollution problems? We asked two experts to give their views.

Forest Smith is a member of Green First, an environmental group:

Our future on Earth looks terrible. We’re filling our country with waste. We can’t breathe the air and the sea is polluted too.

I visited some relatives recently in a small village. They grow their own food and cycle everywhere. They are not rich, but they are happy and healthy. We have too many possessions. Most of us have more things that we would ever need. It’s such a waste!

We must close down most of our factories that would reduce rubbish and the air pollution. We must recycle more, give up all cars and improve public transport. Another big problem is that we live in big cities that are crowded with people. It’s time for us to give up our big cities and factories and go back to a simple way of life.

John Green is a scientist at a university:

“Things are not as bad as Forest says. We all have a bright future. We don’t need to give up cars, but we do need to invent better, cleaner cars that do not pollute the environment. Traffic will still be bad, so we need better public transport. We should also recycle more. But some things are getting better. My sister returned last month after living abroad for five years. She said, “Our city looks different from before—it is cleaner and greener now.

Science has made life better in so many ways. A hundred years ago, most people died before the age of fifty because life was so hard. We can’t go back to a world like that.”

【1】What’s Green First?

【2】Why do Forest Smith’s relatives grow their own food?

【3】who thinks we should invent cleaner cars?

【4】Why does Forest Smith suggest closing down most of our factories?

【5】What do both experts think we should do to deal with pollution problems?

【題目】閱讀短文,完成各小題.并將答案用0.5毫米黑色簽字筆填入答題卡相應(yīng)的位置上.

Most new people were born in developing countries. These countries are found in much of Africa,South America and some parts of Asia. In the developed countries of Europe and North America,the population is growing slowly. This is because women in the countries have,on average (平均),only one or two children. In the developing countries, many women have five or more children. In 1950,around one quarter of the world's population lived in the developed countries. By 2050, these countries will be home to only around one tenth of the world's people.

In the developing counties more than one billion people are still living below the poverty(貧困) line. These people do not have enough food to eat and they live in poor houses. Children get little time at school and people suffer(遭受痛苦) from many kinds of diseases.

At the beginning of the 21st century,the world's population was around six billion. The UN(聯(lián)合國)has said that the world's population will continue to grow,reaching 14 billion before it becomes stable(穩(wěn)定的),or even falls.

【1】In what areas(區(qū)域) of the world can developing countries be found?

【2】Why is the population growing slowly in the developed counties of Europe and North America?

【3】In 1950,what percent of the world's population lived in developing countries?

【4】How can we describe the people living below the poverty line?

【5】According to the UN,what will the world's population reach?
