【題目】—How much______this pair of socks?

—Only six yuan.

A. is B. are C. be D. does

【答案】A

【解析】句意：-這雙襪子多少錢？-只6元錢。is和are都是be動(dòng)詞的形式，is用于主語(yǔ)是單數(shù)的時(shí)候；are用于主語(yǔ)是復(fù)數(shù)的時(shí)候；does是一個(gè)助動(dòng)詞。句中How much詢問(wèn)的是價(jià)格，句型是How much + be+主語(yǔ)，故D不對(duì)。這句話的主語(yǔ)是this pair of socks這雙襪子，socks單獨(dú)做主語(yǔ)的時(shí)候，謂語(yǔ)動(dòng)詞應(yīng)該用復(fù)數(shù)，但當(dāng)有a pair of或者this pair of修飾的時(shí)候，謂語(yǔ)動(dòng)詞應(yīng)用單數(shù)。故應(yīng)選A。

【題目】 Trees are one of the oldest “citizens” of our earth. They keep our air clean, reduce noise pollution, improve water quality and provide food and building materials.

Just like us, trees change a lot as they grow. At 1 to 3 years old, young trees learn how to grow up safely. For example, many trees grow thorns to warn animals not to go near. Most young trees have large, deep green leaves so that they can catch enough sunlight and change it into their food and energy.

When trees are 4 years old, they begin to grow very rapidly and become strong enough to face challenges later in life. At the age of 15, trees become young adults. They grow more slowly and begin to produce flowers and fruit.

It is not until the tree is 20 to 25 years old that it becomes a real adult. The tree reaches its largest size. The adult tree gives us shade, oxygen and natural beauty. It is also a great place for a tree house, or a place for us to read a book, listen to music and so on. If we give the adult tree proper care, it will go on to live healthily for many years.

Gradually, trees begin to grow older and older and even die. At this time, they still have their important place in nature. When a tree becomes hollow or part of it becomes dead, it provides a home for small animals and is a source of food for many other animals.

In many ways, the life of a tree is similar to our own life experience. When we are looking at the life of a tree, we learn that each period of life brings its own form of joy and challenge. Enjoy every minute of the life of the trees and look after the trees!
