阅读随笔

In many cities, summer heat is no longer just a matter of discomfort. It can affect people’s health, raise the demand for electricity and make some neighborhoods far hotter than others. Urban trees are often presented as a simple solution, but their benefits depend on where and how they are planted.

A tree can cool a street in two ways. Its leaves provide shade, reducing the amount of sunlight that reaches roads and buildings. The tree also releases water vapor through a process called transpiration. Together, these effects can lower the temperature around a shaded area. Yet planting trees does not automatically make every neighborhood cooler. Young trees may take years to develop a wide canopy, and trees planted in narrow spaces may not receive enough water or sunlight to grow well.

City planners therefore need to consider more than the total number of trees. A map showing where residents experience the greatest heat can help officials decide where new trees are most urgently needed. Areas with little shade, high concentrations of buildings and large numbers of elderly residents may deserve priority. In addition, local communities can help maintain young trees by reporting damaged branches and watering them during dry periods.

The choice of tree species also matters. Some trees provide broad shade but require more water; others are better suited to dry conditions but grow slowly. A diverse mix of species can make an urban forest less vulnerable to disease. If a single disease affects one type of tree, other varieties may continue to provide shade. This approach may require more planning at the beginning, but it can reduce the risk of losing many trees at once.

Urban trees cannot solve every problem caused by rising temperatures. They need space, care and time, and they work best alongside other measures, such as reflective roofs and well-designed public spaces. Still, when cities plant the right trees in the right places and look after them over time, the result can be more than a cooler street: it can be a healthier and more comfortable place to live.

试题

  1. What is the main idea of the passage?

    • A. Urban trees can replace most other measures for dealing with heat.
    • B. The cooling effects of urban trees depend on careful planning and continued care.
    • C. Cities should plant only trees that can grow quickly.
    • D. The main purpose of planting trees is to reduce electricity use.
  2. According to the passage, how do trees cool a street?

    • A. They block wind and absorb heat from nearby buildings.
    • B. They reduce traffic and encourage people to stay indoors.
    • C. They provide shade and release water vapor.
    • D. They reflect sunlight back into the atmosphere.
  3. Why does the author mention maps showing where residents experience the greatest heat?

    • A. To explain how cities can identify places that need trees most urgently.
    • B. To show that maps are more accurate than residents’ reports.
    • C. To argue that elderly residents should move to cooler neighborhoods.
    • D. To compare the cost of planting trees in different areas.
  4. What is an advantage of planting a diverse mix of tree species?

    • A. Every tree will require the same amount of water.
    • B. The trees will grow faster in narrow spaces.
    • C. The city can avoid caring for young trees.
    • D. A disease affecting one type of tree is less likely to destroy the whole urban forest.

谜底剖析

第1题:B

文章先说明都会高温带来的问题,,随后先容树木降温的两种方法,,再讨论选址、树种和后期维护。。。最后强调,,树木需要合适的所在、照料和时间,,并应与其他步伐配合。。。因此,,文章重点不是说树木能解决所有热问题,,而是指出妄想与维护决议着实际效果,,B归纳综合得最完整。。。

A把树木说成可以替换大大都其他步伐,,与末段“还需要反射屋顶等步伐”相反 ;;C将“树种选择”误读成只种速生树 ;;D只提到可能降低用电需求,,并不是全文主旨。。。

第2题:C

第二段明确写出两种降温方法:树叶遮挡阳光,,为蹊径和修建提供阴影 ;;树木通过蒸腾释放水蒸气。。。C同时归纳综合了这两点。。。A、B、D都加入了随笔没有说明的机制或效果,,尤其文中没有说树木通过反射阳来临温。。。

第3题:A

第三段提出,,都会妄想者不可只统计树木总量,,还要审查住民在哪些地方遭受更强的热。。。热量高、遮阴少、修建麋集且晚年住民较多的区域,,可以优先获得新树。。。地图在这里是资助确定莳植所在的工具,,以是选A。。。随笔没有较量地图和住民报告的准确性,,也没有提出让住民搬家。。。

第4题:D

第四段指出,,多样化莳植可以降低都会树林受到疾病影响的危害:一种树熏染疾病时,,其他树种仍可能继续提供遮阴。。。D准确对应这一因果关系。。。A、B、C均不切合原文,,文章反而提到差别树种对水的需求可能差别、部分树种生长较慢,,并且幼树仍需社区资助维护。。。

随笔参考译文

对许多都会而言,,夏日炎热已不但是令人不惬意的问题。。。它会影响人们的康健,,增添用电需求,,还可能让一些社区比其他地方热得多。。。都会树木常被视为一种简朴的解决步伐,,但树木能带来几多利益,,取决于种在那里、怎样莳植。。。

树木可以通过两种方法降低街道温度。。。树叶形成遮阴,,镌汰照射到蹊径和修建上的阳光 ;;树木还会通过蒸腾作用释放水蒸气。。。这些作用配合降低树荫周围的温度。。。不过,,种树并不料味着每个社区都会自动变凉。。。幼树可能需要多年才华长出宽阔的树冠,,种在狭窄空间里的树也可能因缺少水分或阳光而长势不佳。。。

因此,,都会妄想者需要思量的不但是树木总数。。。标出住民受热最严重区域的地图,,可以资助有关部分判断哪些地方最急需新树。。。遮阴少、修建麋集、晚年住民较多的区域,,可能应当优先莳植。。。外地住民也能协助照料幼树,,例如报告受损树枝,,并在干旱时为树木浇水。。。

树种选择同样主要。。。有些树能提供宽阔树荫,,却需要更多水 ;;另一些树更适合干燥情形,,但生长较慢。。 ;;煜膊畋鹗髦,,可以让都会树林更禁止易受到疾病影响。。。若是一种疾病侵袭某个树种,,其他树种仍可能继续提供遮阴。。。这样的做法前期需要更多妄想,,但能降低大宗树木同时损失的危害。。。

都会树木无法解决气温升高带来的所有问题。。。树木需要空间、照料和时间,,与反射屋顶、设计合理的公共空间等其他步伐配适时效果更好。。。只要都会把合适的树种在合适的地方,,并一连照料,,获得的就不但是一条更凉爽的街道,,也会是更康健、更宜居的生涯情形。。。
