A．improveB．to improveC．improvingD．improved

分析 聯(lián)合國(guó)幫助保護(hù)人權(quán)并發(fā)揮改善國(guó)際法的作用．

解答 答案：B
句中and連接并列謂語(yǔ)helps和works；improve表示work的目的，在句中作目的狀語(yǔ)．故選B．

點(diǎn)評(píng) 動(dòng)詞不定式是非謂語(yǔ)動(dòng)詞是一種，表示未發(fā)生的動(dòng)作，用法較多．常用來(lái)作定語(yǔ)，主語(yǔ)，賓語(yǔ)，補(bǔ)語(yǔ)，狀語(yǔ)等．本題中用來(lái)作目的狀語(yǔ)，相當(dāng)于in order to為了．

1．All plants need water to grow．Watering plants seems like a simple task but it actually requires many considerations．For example，plants growing in areas with low rainfall or areas （33）exposed（expose） to dry wind require more water．On the other hand，plants which have a good adaptation to dry conditions or have the ability to store water in their cells require（34）less frequent（frequent） watering．The watering of plants should not be viewed as a minor process in gardening （35）as/for/because/since this task plays an extremely important role in ensuring healthy plant growth．
Let's first take a closer look at plants growing in gardens．Since watering is a critical gardening task，（36）an accessible water supply is vital．A garden tap with a hose of sufficient length to reach the furthest part of the garden （37）is preferred（prefer）．This tends to make watering much easier and ensures adequate water is provided for the plants．Most inexperienced gardeners water little （38）butvery frequently．This is undesirable as it encourages shallow root growth．In addition，watering in full sun causes leaves to lose water quickly from the surface of the soil．Therefore，some experts recommend（39）installing（install） an automatic watering system．
As for plants growing in pots or containers，they tend to lose water rapidly．One way to reduce such a risk is （40）to grow（group） the plants close together to keep moisture．Try to move them to a shady place if you are away from home for a few days．Otherwise，you will return home to see your plants dead．
